Human vs Plant light response FAQ - Frequenty Asked Questions What is PAR light? It may come as a surprise to learn that plants don't actually "see" the same light we do. The photosynthesis reaction that makes plants grow reacts to only certain light wavelengths (colors). This is exactly what PAR light is (Photosynthetically Active Radiation). This means that if you buy a traditional white light, you will be giving your plants lots of extra light that it can't even use! And guess what? That's a huge waste of energy!

So why LEDs? LEDs (Light Emitting Diodes) emit only certain wavelengths of light and have a fantastic lifespan (around 50,000 hours), making them the perfect solution to efficient plant growth. The reason why LED growing is not commonplace is because it has been difficult to find LED lights powerful enough to to sustain good growth. Technology has rapidly advanced in this field, allowing us to offer record breaking high-output LED lights that will skyrocket your plant's growth while consuming 75% less power!

Why don't you list the LUX or Lumens on your lights? We could, but it would be a meaningless measurement.

Lumens are a measurement of how much light energy a light source emits. The problem is that this measurement is based around the wavelengths of the human eye, and NOT the PAR wavelengths. Using Lumens is great for measuring light used in flashlights or office buildings, but completely worthless when it comes to grow lights.

LUX is simply a measurement of how much light reaches a surface (Lumens/m^2), but again this measurement is based upon lumens which is totally irrelevant for our purposes. Legitimate PAR measurements are as follows: PAR watts per square meter, PPF PAR, and YPF PAR. These are, unfortunatly, very hard to measure correctly. Very few (if any) vendors will provide you with these numbers because they simply do not have a way of calculating them.

Any vendor that tries to sell their lights based on LUX or Lumens is just trying to trick you!

I have heard LED grow lights produces poor results, true? Nothing could be further from the truth! Bad LED Grow Lights Unfortunately 99% of the LED grow lights on the markets are simply scams and many people have taken this to mean that LEDs just don't grow plants very well. The truth is NASA is using LED Grow Lights in space right now with great success!

This technology works, the problem is that it isn't as simple as throwing a bunch of red and blue LEDs on a board and calling it a grow light. The LEDs must be extremely high output, have the correct wavelengths at the correct ratio, and must be powered and cooled effectively. Lights like the one pictured on the left are a total gimmick and will certainly perform poorly (if at all). Real LED grow lights will not look like this because of the power requirements and heat output that come from LEDs suitable for growing.

The LightBlaze 400 is by far more advanced than any other LED grow light on the market. We use the same high output LEDs that are used in street lights and power them with a built in power supply and cooling system.

So the quick answer is: Most LED grow lights on the market will simply
not work
, but when done properly LED growing is the most effective way to grow plants in the modern world!

Where is the reflector? With LED technology no reflector is needed! This is because LEDs are already directional lights. Traditional light bulbs will produce light in a full 360 sphere requiring some sort of reflector to direct the light. Reflectors are never 100% perfect and will always result in some light being lost to heat/absorption. This is yet another way where LED technology beats conventional lights in efficiency.

Do I need to use a fan? Compared to HID (High Intensity Discharge) lights, LED lights produce very little heat. This means you can safely forgo energy-consuming fans and other exotic cooling solutions. You may wish to use a small fan to simulate a breeze for plant strength, but no extra fan is required for cooling. This means even more savings on the power bill, and another reason to make the switch to LED grow lights

How high do I hang the LightBlaze 400? We recommend position the light 12-24 inches from your plants.
