I don't endorse any of the commercial LED light systems that are out right now. Some are actually very good products, I just feel the price point is set way too high right now on this new technology, so I decided to build my own to see how much cheaper I could do it myself. I am not going to duplicate my notes here because they are extensive, but if you do a google search for my name along with DIY LED project, I am sure you will find me. You will find in my notes some extensive comparisons between lifetime cost and efficiency of LEDs compared to all the other popular light systems out there, information that I was not able to find on the web and was forced to compile on my own. I am still in the process of building these lights, so the notes are not complete, but it will give you a better idea what you are dealing with.

Two lights or one is really dependent on many things... not enough information to answer that question for you. One of the questions that I am trying to answer myself is just how much LED light is necessary to equal a 400w or 600w or even 1000w conventional setup. LED light changes how a garden reacts appreciably, not needing as much water as conventional systems, among other things. I am also convinced that the chromatically pure light is much more powerful as far as the plants are concerned, and I think that decent gardens can be grown under this pure light with far less wattage than is currently believed to be possible if the light is exactly what the plants need and it is served up very close to the plants to reduce the effects of the inverse square law regarding the distance from the light. Much more experimentation is needed in this arena and I hope that my work helps to get more people to move to LED technology, and as more and more of us build these lights ourselves, the prices of the commercial lights will have to come down. Currently I can build a light for about 1/3 the cost of a comparable commercial LED array, the markups on this technology are so great.
