if they flame you it is from lack of knowledge or talking to somebody who used inferior product and saying LED's don't work.

some folks have built there own panels such as Weezard..he has great photo album...Dreaded Hermie...Khyberkitsune has great scientific knowledge of how they work...and obviously look at mine

but i am saving approx $200/month in energy by cutting out the AC and 2 1000w HPS and 1 600w MH then i also have no bulbs to replace for ten years and with bulb replacement cost and energy i will save approx(on todays rates) $29,000 over a 10 year span so i am basically getting a new truck for growing with LED's:jointsmile:
