Excepted yield per Watt and number of lights
Excepted yield per Watt and number of lights
The number of lights you need depends upon how much yield you would like from your grow area. We advertise that our lights achieve 1 gram per Watt (1gm/W) of dried product, so about 250 grams per SK450. Our more experienced users regularly yield 1.2 – 1.5 grams per Watt using the correct combination of grow methods and supplements. However, this is something we avoid advertising due to liability issues, as there are so many variables to growing indoors that we have no control over.
As mentioned near the top of this section, we advertise that any reasonably competent grower will be able to yield 1 gram of dried product (such as ghost peppers) per watt of power consumption (25W=25gm; 250W=250gm). However, we have many satisfied customers that regularly yield 1.2-1.5gm/W, and more, using the correct combination of grow methods (see below) and supplements. These figures meet or exceed all other grow lighting efficiencies.
How should I mount my Super Grow LED Lights?
This is a matter of preference. Some people choose to mount their LED grow lights with hooks, chains, string, etc. A popular solution is to use “yo-yo’s” made from rope or wire that will support the weight of the SGLEDs. As our LED grow lights weighs in at about 5 pounds (2.26 kg), several may be hung from a pair of yo-yo’s. The SK450 weighs approximately 20 pounds and we regularly hang two of these per set of yo-yo’s.
To hang an array of four or more units, some of our customers choose to build a very inexpensive frame from locally available PVC pipe, which can be found at your local home supply, DIY or plumbing store. They then hang the frame from the ceiling, and then hang the lights with bolts attached to holes drilled through the PVC. Most customers drill many holes in their frames so that they may move the SGLEDs around as the need arises. This is inexpensive and works very well.
How many lumens do your lights put out?
The quick answer is about 14,000 for the SK450. However, this measure is highly misleading, as with ANY LED grow light. Somehow, much of the grow light industry incorrectly advertises luminous intensity as the determining factor for effectiveness of grow lights, including High Intensity Discharge (HID) lighting like Metal Halide and High Pressure Sodium lamps. This couldn’t be further from the truth. For instance, blue LEDs, which are also the base frequency for most white LEDs, are not measured in lumens due to the high frequency and subsequently greater power. They are measured in radiometric power (in Watts) and converting this power to luminous intensity is subjective.
A simple analogy that should illustrate the uselessness of comparing lumens to effectiveness: Tape 100 X 300-lumen flashlights together and use them the same way you would any grow light. Even though they put out 30,000 lumens, they won’t grow a plant!
So, how do you rate your LED grow lights?
We prefer to deal in scientific fact and we have been doing so for over 10 years. Going back to basic biology, plants have photoreceptors in their chloroplasts that receive and react to photons in specific frequencies. The chloroplasts then create food (energy) that is utilized by the plant for every function and growth, from seed-to-flower. The amount of food a plant can produce is dependent upon much, much more than just light, i.e., water availability, pH levels, CO2 and oxygen levels, nutrients, temperature, drainage, photoperiod, latitude, etc., but the photons (light) kick everything off.
Plants need light all the way across the spectrum, to include the chlorophyll absorption peaks, as well as the many “antenna” photoreceptors that assist the chlorophyll processes. Too often, manufacturers totally ignore these important frequencies, as well as other plant lighting requirements, such as that which serves the beta-Carotenes, luteins, and lycopenes.
Plants can use virtually ALL of the visible spectrum to aid them in development – to waste anything would be foolish.
There is more detail below, in the FAQ section “Are your LED grow lights “broad” or “full” spectrum?”.
What can I grow with the Super Grow LED?
Anything! Due to our full spectrum spread and efficient photon delivery, growing with our lights is highly effective for every plant we have come across. This includes roses, orchids, vegetables, herbs, spices – anything! We have also shown great effectiveness dishing up photons to algae and marine life, such as fish and shrimp.
Is there any special way I need to grow my plants?
Absolutely! And this is recognized as true for any lighting that you use to grow indoors.
Most successful LED growers use the Sea-of-Green (SOG), or Screen-of-Green (SCROG) growing methods. This concentrates all of the fruiting sites to the tops of the plants and the branches below this “canopy” are usually pruned away. As LEDs do not have the sheer (and mostly wasted) power of more traditional lighting technologies such as Metal Halide (MH) and High Pressure Sodium (HPS), they subsequently lack penetration through this canopy to the underlying leaves.
Assuming you are already familiar with growing your crop of choice, the rest of the formula you would normally use remains the same, with one exception – if you live in a very cold climate, you must insure your crop has enough heat to survive – LEDs do not provide the excess heat of High Intensity Discharge (HID) lighting.
Can I combine the SGLEDs with traditional lighting?
Some of our most successful customers combine more traditional lighting, such as MH and HPS lamps, with our LEDs.
By far the most successful grow we have witnessed is a hybrid system in 5’x5’ tents. This grower uses 400W HPS in the center of the tents and has four lights spaced around the HPS in one tent, and six of our lights around the 400W in another. By comparison, a 1000W HPS is run in another tent, using the same plant genetics and nutrients in all tents.
His hybrid setups outperform his 1000W setup
This represents a 50% power savings in energy and cooling costs, while maintaining crop yield

Are your LED grow lights “broad” or “full”spectrum?
Our lights are truly full spectrum, meaning, we provide photons in absolutely every frequency across the visible spectrum.
Some manufacturers and vendors use broad and full interchangeably, but beware – they are not the same.
While providing light in 5 – 11 different frequencies may be considered broad, there are a lot of holes between these frequencies.
You will see many claims that only a few frequencies corresponding to the Chlorophyll A and B absorption peaks are all that are necessary to grow plants. NOT TRUE. In over 10 years of grow light development, we have proven in our labs that plants thrive in full spectrum grow lighting. It is scientifically well-documented that most plants can use the entire spectrum for photosynthesis. Some rationalize their position by stating that we observe that plants are green because they don’t absorb ANY light in the green range. Again, NOT TRUE. The reason we see many plants as green is that plants do not absorb AS MUCH light in this frequency range, and that the difference between a plant’s ability to absorb (for example) red light and green light is as little as 3%-5%. The result – more green light is reflected than red, and we observe this reflected light (as green).
Whose LEDs do you use?
We use 45mil (not the cheap 39mil) chip and die sets from a very well-known and reputable manufacturer. We have these chips mounted in our own configuration for thermal and spectral performance. Our primary full spectrum LED is our own formula, built for us from our exacting specifications, based upon 10 years of functional and operational testing. We are able to do this based upon over a decade of relationship building with LED manufacturers, the LED design industry and LED luminaire manufacturers.
More about our LEDs
Our ties to the LED and manufacturing industries enable us to purchase select parts that others have no access to. Manufacturing an LED is not yet an exact science and white LEDs are rarely exactly alike in frequency (color) and intensity, even those that come off of the same production line at the same time. The result is that LED providers “bin” their LEDs, meaning they test them and place them in virtual bins based upon their output color (frequency) and by power tolerance. For someone to draw from a specific bin to insure consistent performance from light to light is prohibitively expensive, yet that is exactly what we do. Our LEDs are on frequency every time.
The standard LED purchased by many of our competitors may deviate from the frequency required by plants (in the case shown in the graphic, for Chlorophyll A blue absorption). While their LED provides some output in this frequency range, it may not be very much. Our LED provides significantly more power in the ranges that count, allowing us to provide more growing power using less light. The red shaded area represents the amount of light delivered in the correct frequency range by our competition, while the green shaded area represents our fulfilment of the plant’s lighting requirements.
Think about this when you see our competitors increase their power by 200-300%, but their coverage area remains the same. Many cite “penetration” as their reason for jacking up the power (and the cost), but there are gardening techniques to increase yield with less power. There is also significant scientific evidence that over-driving a specific frequency may interrupt a plant’s normal respiration cycles.
How does your light compare to other LED grow lights?
What is your stance on PAR?
We agree that measurement of PAR (Photosynthetically Active Radiation) using a quantum meter is a better method of testing light output for growing plants than using a standard light meter, but it is not the best method. The BEST method is to try the product and determine that it actually works.
Lighting requirements vary rom plant to plant and at different stages of development. Current methods of determining PAR values are hindered by the technology itself. Quantum meters measure photon delivery in a range of frequencies, as shown in the graphic below, but they do not discriminate between frequencies, nor do they tell you if your plants are getting the lighting they need to thrive.
Furthermore, most quantum meters used in gardening only measure light from 400nm (blue) to less than 700nm (red). Quantum meter manufacturers weight the values of certain frequency ranges to accommodate the human eye. As such, these meters are far less sensitive to light produced at the blue end of the spectrum and give greater value to those frequencies in the yellow, green and red spectrum. So, PAR is not as telling as some would have you think. As in our previous example above, strap a bunch of high-powered flashlights together and the measured PAR value may be astronomical, but you would not grow plants with it, making the claim useless.
Hybrid = HPS + LED Comparison
We contacted a few of our customers that we knew to be die hard High Pressure Sodium (HPS) lighting fans, yet chose to try our lights because of potential electricity and air conditioning cost savings and increased yield-per-Watt. All of these customers chose to build a “hybrid” lighting system, using smaller-than-normal HPS lamps and our LED grow lights to improve their results. Collectively, they found that the hybrid setup saved them money, beefed up the plants in their fringe areas, and provided much needed additional lighting spectrum to the plants not normally present with HPS lamps. Further, a very important by-product of using a combination of HPS and LED grow lights is that the HPS lamps provide just enough heat to the plants that would otherwise be missing in an LED-only grow operation.
