A poor man’s Kessil overhead planted aquarium light system.

Kessil a division of DiCon the parent company, aquarium can lights have been around for some time now and it is unmistakable that they have further the popularity of the aquatic planted aquarium interest. They have now through obsolescent, single handedly crush the Metal Halide lights of days of yore that we hobbyists use. With their cool operation, high light output to electrical power consumption with LED cluster magnification system and adjustable light output they have achieved a highwater mark for what other lighting systems now must achieve. They are very compact into a small can size light fixture and allow easy access (because they sit above the tanks water surface by several inches) for tank maintenance without the burden of removing light strips that sit on top of the aquarium. That was one thing I always disliked about strip lights, once removed, now you can’t see in the aquarium to do water changes.

The reviewers rave about Kessil lights to the point that the reviewer must now try and justify the very expensive cost to the number of LED’s in the unit to dollar amount. This cost however does make this lighting system a little difficult for most hobbyist to afford. The cheapest I have found the two Kessil light models for is $239.oo for the Tuna Sun A160WE and $399.oo USD for the bigger A360WE respectably. Add on a Kessil A series gooseneck mount and that adds another $39.oo USD to the price for each lamp can. If you’re like me and live in a state that makes sure you pay your fair amount of state taxes on internet purchases add 10% more on all orders out of state from internet purchases and you are looking at a whopping $305.80 for the Tuna Sun, the cheaper of the two can lamps.

The one caveat about the Kessil is; it’s hard to justify such a cost of a Tuna Sun for a 20-gal aquarium or better yet, a four-foot aquarium will need two of these lights and now $611.60 USD is out-the-door just to light up a 55-gal aquarium… are you kidding me? No matter how you do the math or try and justify the cost to the number of LED lights, this definitely does not give the impression to be a great deal. But, apparently to some hobbyist this price point, though expensive, is still better than the strip lights that are presently out there. Plus, the Kessil lights gives that shimmer affect at the bottom of the tank that so many hobbyists love to see, just like the Metal Halides do.

Okay, what does all this have to do with the poor man’s Kessil lighting system in my introduction. After some research and experimenting with different lighting systems I found an LED light bulb that has 24 HO LED’s in a small perimeter of 1 ¼” ID that you can add to any light fixture. The lights bulbs are from GE and are called Bright Stik BC Globe in Day Light @ (6500 k) 100w, 1500 lumens of light output as is. You can buy a pair of these light bulbs for $15.95 USD at most retail outlets stores. The only modification that needs to be done to the light bulb, is the removal of the diffuser end cap. It’s because of this end cap the Bright stik is only rated at 1500 lumens. This can either be pulled off or cut off at about ¼” from the base of the light. I just cut the end of the diffuser cap because it was easer that forcibly trying to pry it off. Once the cap is off then the 25-LED’s will be expose and will be in four clusters of six LED’s set evenly inside the circumference of the light bulb.

Just like the Kessil lights that are also very bright because of the cluster of LED’s in such a small circumference; one cannot look directly into one of these Bright Stik lights without some eye impairment, so caution must be taken. The smaller Tuna Sun has 24 LED’s and the larger A360WE has 45 LED’s per light can. So, if you wish to add more light to your aquarium when using a Bright Stik, in other words more LED’s (two will equal 48 LED’s), then add two Bright Stik’s instead of just one to even out the light over the tank; this is what I use on my 27” long aquarium. Each Bright Stik has its own light pendent from Zoo Med (mini size) hanging about 6”-8” from water’s surface. Example: A 24x24x24” 60-gal cubed aquarium would need two Bright Stik’s in a Zoo Med combo deep dome lamp fixture mini.
At Big Apple Pet Supplies in Florida, you can buy a Zoo Med combo for $24.99 USD and I have even fond such for as little as 20.95 per combo on Amazon Plus. The pendent light arms mounts can be bought for as little as $16.95 USD, this is the kind that will stick onto the back of your tank. So instead of paying $305 dollars for a Tuna Sun with Gooseneck mounting arm you can get 200-watts of LED HO lighting for as little as $54.oo USD, that is a cost savings of $251.oo USD. You will still end up with that beautiful tank shimmer that makes the Kessil lights so desirable, too. At the cost for one Tuna Sun and mount you can buy 5 of these combo lighting systems as stated above and have over 1000-watts of lighting system over your aquarium. Imagine placing three of these light combos on top of a 70-gal aquarium, that would give you 8.5-watts per gallon of water @ 600-watts, more than enough light to grow any plant available to the hobbyist all for $162.oo USD. My 400-watt Metal Halide not only would cost more to run in electricity cost than the LED Bright Stik’s(16-watt) but would also create a considerable amount of heat in the tank and outside of the tank, too. Virtually no heat is expended from the bottom of the Zoo Med pendants when the Bright Stik lights have been on for over 10-hours.

I will end this by saying that if the Kessil pendent can lights are your preference then by all means buy what you like and disregard what you have read here. However, if you are like other hobbyist and your wherewithal are in short supply or you can spend your money on better things than on aquarium lights, them by all means check into these Bright Stik’s. I will also make a note here: As an Ichthyologist, I have seen more fish than the average hobbyists will see in their lifetime and these lights bring out the natural colors of fish and plants that closely mimics that of a natural environment at high noon in any aquatic habitat that I have seen. Their color temperature is spot on without the over exaggeration of colors or pigmentation that so many lights give our inhabitance.

LED Grow Lights
In this document we will endeavour to give an overview of terminology in relationship to growing plants
under LED lights, we will do some comparisons between different products and show the range of
products that we offer.
The nature of light
The energy produced by the sun reaches the earth as electromagnetic radiation. Light and other forms of
electromagnetic radiation are considered to have both a wave nature and a particle nature. Particles or
packets of light (its particle nature) are known as photons(the smallest divisible unit) light depends on the
number of photons absorbed per unit time. Each photon carries a fixed amount of energy which
determines the amount that the photon vibrates. The distance moved by a photon during one of its
vibrations is referred to as its wavelength and is measured in nanometres. Electromagnetic radiation spans
a broad range of wavelengths. At the one end of the spectrum of electromagnetic radiation there are
gamma rays which have a wavelength of 10 nm and at the other end, radio waves which have a
wavelength of 1012nm. A very small part of this spectrum can be seen by the human eye i.e. between the
wavelengths 380 and 750 nm. This part of the electromagnetic spectrum is called visible light. Almost all
life depends ultimately on this part of the spectrum for its energy. Humans perceive the different
wavelengths of visible light as different colours. Within the spectrum the longer the wavelength of the
radiation, the slower the vibration of the photons and the less energy each photon contains. Thus photons
of ultraviolet light, at the blue end of the visible spectrum, have shorter wavelengths and contain more
energy than red light and infrared radiation. Sunlight contains 4% ultraviolet radiation, 52% infrared
radiation and 44% visible light. Why is only visible light used by plants?
Light and photosynthesis
Chlorophyll does not absorb all the wavelengths of visible light equally. Chlorophyll a, the most
important light-absorbing pigment in plants, does not absorb light in the green part of the spectrum. Light
in this range of wavelengths is reflected. This is the reason why chlorophyll is green and also why plants
(which contain a lot of chlorophyll) are also green. Note in the graph below that the absorption of light by
chlorophyll a is at a maximum at two points on the graph 430 and 662 nm. The rate of photosynthesis at
the different wavelengths of visible light also show two peaks which roughly correspond to the absorption
peaks of chlorophyll a. Plants do not depend only on chlorophyll a in their light harvesting machinery but
also have other pigments (accessory pigments) which absorb light of different wavelengths.
One of the first questions we are asked is “how bright are the LED lights that you sell?” and what is
their measure in lumens.
Firstly you need to remember that Lux meters (lumens) are designed to measure brightness in relationship
to the human eye, i.e. designed for use mainly with cameras etc, so it is described as a subjective measure,
which is not really of great concern to a plant, there are other meters that measure the actual photons as
they reach the plant and their relevance to the photosynthetic reaction, but this gets all very complicated,
for instance even though blue light registers far less in brightness on a Lux metre when it comes to
photons absorbed by the plant blue actually has more energy then the red spectrum. These type of
measurements are therefore much more accurate when comparing the energy required from light by
plants, however they are still not accurate because they still give value to the wavelengths of light that the
plant may not be using. Unfortunately everybody needs to use the same units for these comparisons to be
of any use, at the moment most people use Lux meters which still have some value as long as you are
comparing similar things, ie two LED lights with the same ratio of blue to red LEDs or if you are
comparing two HIDs, but not really relevant if you are trying to compare a red and blue LED lamp with
an HID.
Also we must remember that we are only talking about the new high power LEDs that run at 1 W or
greater not the smaller LEDs that flooded the market over the last year or so, which will be fine for
growing seedlings but do not really have enough power ie intensity, for a plant to go into flower and fruit
stages successfully.
Probably the best and most expensive LED light on the market at the moment is an American device
called the Procyon see a grow test between a 400 watt high pressure sodium bulb HPS and a Procyon 100
at
http://www.homegrownlights.com/testing.html
At this site http://www.greenpinelane.com/hgl_procyon_test.aspx you will see where tomatoes have been
grown to flower and fruit using this device, they have also done Lux measurements (scroll to the bottom
of the page) over a 3' x 2' or 0.9 m x 0.6 m, roughly half a square metre, you see that the intensity
decreases towards the edges but if you take the highest measurement in the centre at say 18 inches above
the test meter, the highest reading is 7820. Below we have done some similar measurements using our 7
W (1B6R) with 30° lenses LED light and at 18 inches the greatest measurement is 11470 and the 7 W
(6B1R) 30° lenses LED light and at 18 inches the greatest measurement is 4420, the lights on the Procyon
use a ratio 2Red to 1Blue so combining our lights gives a reading of 9120. The Procyon users 56 LEDs
without lenses, they run their LEDs at just under 2Watts giving slightly higher brightness than the ones
that we use, that are run at 1W, however the LEDs that we use will last slightly longer (because they are
not running as hot), and as can be seen by the brightness tests below, by using lenses you can achieve the
greater brightness levels and, this is even more so when you add extra lights together as you do not get
the drop off at the edges e.g. in the Procyon at the edge of the 2 foot square rectangle the measurements
are down to around 2000.
You will see below where the 3x7W (6R1B) LED lights have been placed in a row you see that it covers
the same length as the Procyon without the diminished brightness at either end, being focused it does not
cover quite as much width, but we would suggest using 3x12W (8R4B) LED lights, which would give
you a similar spread, and higher intensities over a more uniform area, and the same ratio of red to blue
LEDs ie 2:1.
The other advantage of using these smaller lights is that not only do they work out cheaper as we have
demonstrated, using lenses gives you higher intensities, but you also have the flexibility of changing the
lenses to suit your particular application, you can even remove the lenses for widespread closer
applications.

What are they and why should we care?
First off, full spectrum is not a purely scientific term, but more of a generalized descriptor of the properties of a light source. Essentially it means that the grow light puts out significant radiation in all bands of the visible light spectrum. Perhaps a more accurate phrase for what we are trying to emulate would be balanced full spectrum, with the average human eye responding to wavelengths from about 390 to 700 nm.

Visible Spectrum

Plants have evolved for millions of years to best adapt to drawing the most energy possible from solar radiation to convert CO2 and H2O into sugar for growth (photosynthesis). Because of this, the absolute best light source known for horticulture is the sun; and for growing marijuana indoors, it will be a grow light that best mimics the intensity and spectrum of the sun.


Cosy Farmer is focus on the indoor gardening、plantpactory and LED plant grow lights, LED aquarium light, aquarium light,UV curing lights, medical and other special LED lighting LED research and development, production, sales, service diversification of an integrated high-tech enterprises.

Thanks very much for the interest in our technology. Our priority as a company is the advancement of this industry and service to our customers. If you have any questions or comments regarding our products please feel free to contact us at anytime.
Traditional full spectrum technology

Traditional LED Grow Lighting manufacturers attempt to recreate a full spectrum output by using 11, 15 or more individual colors or bands.
The final range of output generally falls between 380 and 780nm.

To achieve various output colors manufacturers employ “color mixing” which blends two or more colors to create a third.
While results are indeed achieved through color mixing, the process is inherently inefficient, as proper levels of light crucial for optimal plant development are simply not attained.
We found this issue to be one of the largest drawbacks to current LED technology so we set out to fix the problem.
Pro Grow LED® full Spectrum technology

Our latest advancement allows for a greater spectrum range than currently offered by traditional, single color LED manufacturers. This expanded range falls between 350 and 850nm.
And we only use one chip to primarily accomplish this task.
Hydroponics Hut LLC has been able to incorporate true full spectrum output into a single, extremely powerful chip. Pro Grow LED® units can now accomplish with a single chip what takes other manufacturers 11 or 15 individual colors or more to reproduce.
This increased spectral range allows for performance that actually exceeds the growth rate of the sun itself in an indoor environment.

LED Grow Lights are becoming ubiquitous in the market when looking at options for growing plants without natural light or without enough natural light. If you go back even a couple years people never considered LED for growing plants either in their home or in a commercial grow environment.

LEDs started with a humble beginning in handheld games, indicator lights, holiday lighting, as well as many other common uses. While LEDs we useful for lighting the way for the human eye, the original LEDs were not nearly powerful enough to grow plants. With the creation of high power LEDs in specific colors, LEDs have now become a viable source of light for growing plants… Read More



How Do LED Grow Lights Work?

It is a good idea understand the most fundamental question when looking to buy an LED grow light; what is an LED? LEDs create light through a phenomenon called electroluminescence, where electricity passing through a silicon semiconductor junction results in the creation of photons. Unlike every other grow lighting technology, LEDs do not require heat and/or mercury to create light for use in an LED grow light or other applications such as headlights for your car.



A Brief History of LEDs

Electroluminescence was first discovered in 1907, but the first LED wasn’t created until 1927, although no practical use was found for it. It wasn’t until 1962 that the first visible light LEDs were created, glowing red. In the 70’s other colors of LEDs were discovered… Read More



How Different Color LEDs are Made

The electroluminescence phenomenon used in LEDs can create different colors using different semiconductor materials and slight impurities (called “doping agents”). For LED grow lights, the important colors are created with:

Color Wavelength (nm) Semiconductor material
Infrared λ > 760 Gallium arsenide (GaAs)
Aluminium gallium arsenide (AlGaAs)
Red 610 < λ < 760 Aluminium gallium arsenide (AlGaAs)

Gallium(III) phosphide (GaP)
Orange 590 < λ < 610 Gallium arsenide phosphide (GaAsP)
Aluminium gallium indium phosphide (AlGaInP)
Gallium(III) phosphide (GaP)
Yellow 570 < λ < 590 Gallium arsenide phosphide (GaAsP)
Aluminium gallium indium phosphide (AlGaInP)
Gallium(III) phosphide (GaP)
Green 500 < λ < 570 Traditional green:

Pure green:
Indium gallium nitride (InGaN) / Gallium(III) nitride (GaN)
Blue 450 < λ < 500 Zinc selenide (ZnSe)
Indium gallium nitride (InGaN)
Silicon carbide (SiC) as substrate
Silicon (Si) as substrate—under development
Violet 400 < λ < 450 Indium gallium nitride (InGaN)
Purple Multiple types Dual blue/red LEDs,
blue with red phosphor,
or white with purple plastic
Ultraviolet λ < 400 Diamond (235 nm)
Boron nitride (215 nm)
Aluminium nitride (AlN) (210 nm)
Aluminium gallium nitride (AlGaN)
Aluminium gallium indium nitride (AlGaInN)—down to 210 nm
Pink Multiple types Blue with one or two phosphor layers:
yellow with red, orange or pink phosphor added afterwards,
or white phosphors with pink pigment or dye over top.
White Broad spectrum Blue/UV diode with yellow phosphor

“White”, “Full Spectrum” or “Broad Spectrum” LEDs

There are many different names for the same thing: a blue (or very rarely UV) LED diode covered with a yellow phosphor will create what the human eye perceives to be white light. The invention of practical high-intensity blue LEDs earned a Nobel Prize in 2014 because coating them with a yellow phosphor allowed LEDs to replace all other lighting technologies for humans while significantly increasing lifespan and efficiency.

White LEDs work by covering a high-intensity blue LED and placing a phosphor “cap” on top, usually yellow. When a high-energy blue photon generated by a blue LED strikes one of the phosphor molecules, some of its energy is converted into heat and the rest is re-emitted as a different, lower-energy (redder) color of light. Some blue photons sneak through the phosphor layer, but most are converted to a yellow or red color. This allows highly-efficient blue LEDs to recreate most of the colors that our eyes can see at a significant energy savings compared to incandescent, fluorescent / induction, high pressure sodium and metal halide lights….

“Full Spectrum” LEDs vs. 3-Band, 5-Band, 8-Band or 13-Band LEDs

There are trade-offs between the so-called “full spectrum” phosphor-coated blue LEDs and utilizing multiple different colors or “bands” in LED grow lights.

“White” or “broad-spectrum” LEDs can provide for plants’ minimal needs for growth, and if they are based on UV LEDs (which almost none are) they can even provide all the colors of light plants need to grow ideally. However, they do not produce all of these colors in the ideal ratio for plants. Most “full spectrum” LEDs produce predominantly yellow light, which is absorbed by plants but is not directly usable. The yellow light heats up leaves more than is necessary for ideal plant growth in indoor gardens, requiring additional cooling to keep the plants from overheating… Read More



Why Only Red and Blue LED Grow Lights Don’t Work Well

Plants will grow with only red and blue light, but they will not achieve their full potential without at least some other colors of light.



Understanding the Ideal Spectrum for LED Grow Lights

While plants don’t use each color equally, they do prefer broad-spectrum light. From the lowest-wavelength (highest-energy) to the highest-wavelength (lowest-energy) these colors are:

Ultraviolet (UV) light causes many plants to develop thicker cell walls, pigments, vitamins and other substances in a process called photomorphogenesis. In plants that naturally develop red pigmentation in their leaves such as red-leaf lettuce, UV light is responsible for the pigment production; without it the plants will remain green. In Cannabis, UV light is responsible for increased THC, CBD and terpene production…. Read More



Heat: Thermal Management of LED Grow Lights

Like every lighting technology, LEDs degrade over time and put out less light- they just do it a lot slower than other types of lights, as long as the LEDs are properly cooled. Excess heat causes LEDs to lose brightness and fail faster than if they are properly cooled.

For LED light bulbs used in houses, the small total wattage of the LEDs means that a simple, small “heat sink” can be used to get rid of the excess heat. When you put enough LEDs together to make a high-power grow light, more elaborate cooling is required to keep the LEDs running at peak efficiency for as long as possible. LED grow lights with inadequate cooling designs will dim quickly, even though the LEDs they are made from may be rated for a very long life, because this rating requires them to be properly cooled… Read More



Why Should You Consider Buying LED Grow Lights?

The benefits of using LED grow lights in your indoor grow are numerous and will be covered in detail below where we compare LED grow lights to the other older traditional lighting options. For now we can focus on the benefits of LEDs on their own.

Compact Design

Traditional HID lighting required large cumbersome reflectors along with fans and ducting to run properly. LED grow lights will allow you to simplify your indoor garden. The smaller size to watt ratio of LED grow lights can save a lot of valuable space in your grow, freeing up more space for plants and proper ventilation. The additional space you gain from not having as much cooling and equipment needs allows you to have a better space to work in where you can take better care of your plants thanks to better visibility and access.

Safe and Cool Running Temperatures

The management of the environment in your grow is key to success. High temperatures will cause heat stress at the very least and can cause the entire loss of a crop. To keep your environment at the proper temperature you need to use air conditioning with thermostatic controls. Traditional HID lighting adds huge amounts of heat to the environment since they run over 500 degrees. LED grow lights are only warm to the touch and do not put as much heat into the grow environment. This adds safety to your garden and saves money as well.

Power Efficiency

LED grow lights are much more efficient at producing the light that makes plants grow than traditional HID lighting or other technologies. HID lighting can produce a lot of light but it takes a lot of energy to create this light. Using the more efficient LED lighting will save you in power bills over the long run.

Bulb Lifespan

Replacing bulbs every 6 or 9 months is a thing of the past with LED grow lights. High quality LEDs can last 4 to 5 years without any maintenance or bulb changes. This saves money and time in your grow.



What Does the Wattage on your LED Grow Light Mean

Many LED grow light companies overstate the wattage their lights actually run at, instead using the theoretical limit of the LEDs in the light. If this much energy were run through the light it would likely cause permanent damage to the light and shorten the lifetime of the LEDs. Some other manufacturers will misleadingly name their LED grow lights with the wattage they claim it will replace, such as a 1000 watt HPS.

When buying LED grow lights you should always make sure the company is claiming the actual wattage the grow light will use in your garden. You are essentially paying mostly for wattage when you buy LED grow lights so if you are misled in the wattage you are not getting what you are paying for.



Light Cycles in Your Garden

Every garden has a light cycle. Depending on what stage your plants are in (flowering or vegetative) you will need to set up your lighting to turn on and off at the proper intervals. You need to understand how this works if you are going to succeed and get a solid harvest out of your garden.

In nature, outdoors, plants follow the seasons and while water and temperatures can play into this, the length of day also sends signals to the plant. As the summer turns into fall and fall turns into winter the days get shorter and the nights get longer. In your indoor garden you control the seasons by using a timer with your light to control the day and night length.

Some plants decide when to flower based on the length of the day / night cycle. Plants such as lettuce flower when the nights get short; plants like cucumbers will flower when they are large enough regardless of the length of the day or night.

Cannabis-Specific Light Cycle

Cannabis plants flower when the days get short and the night gets long. Cannabis determines this cycle based on the amount of dark time it receives every day… Read More



Vegetative Growth

Once a plant has left the seedling stage or the cloning stage, if coming from a clone instead of a seed, it will remain in the vegetative state until you are ready to flower the plant. During this stage you need to provide your plant with a longer time period of light from your LED grow light but the light can be less intense than during flower. Due to this lower requirement of power you can use less watts per square foot and save money on both the cost of the LED grow light as well as the savings from the more efficient LEDs.

During the vegetative period we recommend 16 or 18 hours of light per day. How long you remain in vegetative state before going into flower will depend on many things such as how large you want them to be at the end of flower, the particular genetics you are working with, and your style of growing (sea of green, screen of green, etc.). Other external forces can affect the duration of veg can be items such as a relatively short ceiling which can require you to keep plants smaller… Read More



Flowering Your Plants

To switch the light cycle on your LED grow lights to the 12/12 of light/dark for flower is often referred to as “flipping” the plants into flower. Once you make this change to 12 hours of darkness you need to be careful to ensure the dark period is uninterrupted with no light getting to the plants. If your plants are exposed to light during the dark period they will become stressed and your yields will be affected, or you will have none at all.

Once you flip into flower the plants will generally grow rapidly for a period of time dependent on the strain you are growing. This is called “stretching” and it will happen until the plant diverts all energy to growing flowers. The spectrum in well-designed LED grow lights will minimize this stretching by creating a hormonal response using specific wavelengths (colors) in specific ratios.

Part of moving to flower is increasing their feeding through nutrients and also changing the nutrients to be specific to the flowering cycle. Select a reputable nutrient company and follow their instructions before branching out and mixing and matching different nutrients. Some say that LED grow lights cause the plants to use less nutrients but this is not based in any science. In fact the nutrient needs can go up with LED grow lights if the temperatures are correct and the light is the proper power for the size of garden… Read More



Why use LEDs in your indoor garden?

While other lights such as HPS have been used for over 30 years in indoor gardens, they were created specifically for lighting with the human eye in mind. It was only later people realized they could be used for growing plants as well as lighting a ballpark or parking lot. LED grow lights can be tuned specifically for plants by selecting specific nanometers (colors) that are much more efficient for growing plants and waste less energy. Of course LEDs are inherently more efficient than other lighting technologies so they are particularly well adapted for use in grow lights.

If you care about the planet as well LEDs are a superior choice. All HID bulbs must contain toxic heavy metals such as mercury to work. Every time a bulb is replaced more heavy metals need to be disposed of.

When looking to buy grow lights the obvious choice has become LEDs thanks to the advances in technology and the proof offered for better yields with higher quality.



Automating your LED Grow Lights

LED grow lights are easier to turn on and off than traditional HID lighting since they do not require a cool-down period after turning them off. However, you should still automate the process of turning the lights on and off using a timer. A quality timer is recommended since the less expensive models may have a problem handling the power requirements of larger LED grow lights.





Why is it so Important find the Best LED Grow Lights?

There are many advantages of use LED grow lights in your grow instead of traditional HPS or other lighting. These advantages include but are not limited to lower power use per fixture, reduced cooling needs, increased quality, increased output per watt, fewer maintenance needs, etc. But once you come to the final conclusion that LED grow lights are the best way to go, why is it so important to buy the best LED grow lights, how do you know what the best lights are, and how do you find these lights?

In the past with indoor grow lights it was less important to completely understand the purchase you were making. A HPS bulb from one manufacturer was very similar to a HPS bulb from another manufacturer. Yes, there were some quality and longevity differences but since the core technology of how HPS works did not allow for too much variance between products. Today you often hear people say LEDs don’t work because they or someone they know tried some LEDs and they didn’t work as advertised. The problem with this conclusion is that they tried one brand of LEDs and failed. While there are LED grow light products being sold that do not work, there are ones that do. Trying one brand and concluding all LED grow lights do not work is just not an accurate assessment of the technology.

Avoiding this problem of buying LED grow lights brand that doesn’t perform is key to saving time and money. To avoid this you need to understand what makes LED grow lights so revolutionary for growing indoors and you need to ensure your selection has all of these advantages in place… Read More



Best Priced LED Grow Lights for Quality

If you compare LED grow light prices before buying them you will need to find a way to compare one brand of LED-grow-lights to another brand of LED grow lights. Older technologies such as High Pressure Sodium (HPS) have bulbs that are very similar in quality with only minor variations in longevity and spectral output due to the limitations of the technology. With LEDs the range of grow lights goes from lights that won’t even keep a plant alive to lights that will outperform any grow light in the world.

By dividing the cost of a light by the actual wattage of the light you can determine the cost per watt. You can use this cost per watt number to compare one LED grow light to another with equal quality and features. Just looking at cost will likely give you a light that will break quickly or won’t grow plants well, so it is critical to consider the lights’ features, warranty and build quality as well.



Build Quality in LED Grow Lights

Commercial grade, heavy duty equipment is required if you want your grow lights to last in the demanding environment of an indoor garden. Build quality includes things like a heavy-duty metal housing, use of quality components throughout the construction, and a full spectrum including UV and IR light. Low-end components can result in inferior quantity and quality yields, short lifespan for the light, as well as unsafe operating conditions. The main consideration when looking at build quality when buying LED grow lights is heat or thermal management for the LEDs. If heat is not removed from the LEDs properly, it will build up and cause the LEDs to degrade prematurely or even fail completely. The best way to remove heat quickly and effectively is to use active cooling with moving air. This is attained through the use of cooling fans and allows much more power to be run in a much smaller package safely and effectively.







Which are the most Advanced Grow Lights for Flowering Cannabis?

There has been talk for many years about whether or not LED grow lights work for flowering Cannabis. Not only do LED grow lights work for flowering Cannabis, but the most advanced LED grow lights are available to the home gardener or the commercial grower. These LED grow lights are not only more efficient at creating high quality yields, but also doing so while providing significant savings on air conditioning and cooling costs as well.



Comparison of Grow Light Technologies

There are many different technologies for creating light, some of which can work for growing plants indoors. There are a lot of choices- here’s a basic summary table:

LED Grow Lights vs. Fluorescent (T5)

fluorescent grow lightsFluorescent lights work by passing electricity between two electrodes in a glass tube filled with a low-pressure mixture of gasses including xenon and mercury. When electricity excites a mercury atom, it gives off a photon of ultraviolet (UV) light, which is not visible to humans. To convert this UV light into visible light, the inside of the glass tube is covered with chemicals called phosphors. When a UV photon hits one of these phosphor molecules, some of its energy is converted into heat and the rest is re-emitted as a different color of light. Carefully selecting and mixing the phosphor chemicals creates several different colors of light, which the human eye perceives as white. Varying the proportions of the phosphors can create redder, “warm white” light, or bluer, “cool white” light… Read More
