1. Use less power

2. Produce less heat

3. No noisy, power robbing ballasts

4. Extremely low maintenance (100,000 hr life)

5. Produce only the light your plants need.

Save 75% on power over HID lighting, plus reduce or eliminate power consumption by cooling systems. Plants can use nearly all of the light emitted from LED lamps. This is not the case with HID lights, which produce a lot of light in the infrared spectrum, and high pressure sodium bulbs that emit mostly yellow light due to the sodium emission spectrum.

For those of you who have purchased LED lights before and been less than satisfied with your plant growth, we apologize. NOT ALL LEDS ARE CREATED EQUAL! There are a lot of slick salesmen out there who would try to sell a bucket of water to a drowning man. We are constantly trying to unravel the damage they have done to our industry. Here is a quick overview of LED lighting technology, and comparison to other lighting schemes.

First, let’s discuss what a lumen is, and what it isn’t. Lumens are a very common way to describe how bright a light source is. You might see it listed on the back of a fluorescent light package, or a home theater projector brightness specification. Lumens are good at telling us how bright something looks to a human. Humans can see a very narrow range of the light spectrum. Some colors appear brighter than others. It’s the reason why a yellow sign looks brighter than a blue sign. If we graph the different wavelengths (colors) of light, and compare them to how bright they appear, we get a graph called the luminous efficacy graph:


Basically all it says is yellow and green light appears really bright compared to red and violet light. Lumens are based on this chart. If you want to get technical,

Luminous flux in lumens = Radiant power (watts) x 683 lumens/watt x luminous efficacy

Now the real question that should be in your mind is “What’s good for my plant(s)?” Here is a graph showing what chlorophyll uses to produce energy in your plants:

The photosynthetic rate is what determines the energy available to a plant. Obviously higher is better. Compare this graph to the sensitivity of the human eye. It’s just about reversed! Green, in the ~550nm area is very very bright to us, but very very worthless to a plant. If you put a green mylar filter over your plant lights, you might as well throw your plants in a dark room because they will wither and die. The reason plants appear green is because they reflect green light!

This is exactly why using lumens to measure the brightness of a light “doesn’t work” with plants. A plant would much rather have 10 lumens of red light than 100 lumens of green or yellow light.

 LED grow lights are revolutionizing the indoor growing arena! They consume less power by delivering ONLY the light your plants need, and produce much less heat. They are also mountable in any direction – you could line a cabinet with them if you so choose.

At LEDSOPTIC Grown Lights, we are striving to provide you with the BEST grow lights. If you have any questions about any of our lights, don't hesitate to contact us.
