Does any LFS in the VA,DC, or MD carry it. I think I make the jump, for what I use in electricity for 3 - 400w MH, 2 140w VHO's and 1/2 HP chiller, and the lack of heat so less evaporation, sound good to me, but yes the price is high, but it will be years before they come down. I know when the first LED tails came out for commercial vehicles, they where $120 for a 4 inch tail light in 1998(100,000 hrs) and amost 10 years later there are cheap one the last 2 to 5 years, but the the good one are still $69 to $90 each. I just don't see the price going down in the next 5 years and with replacing bulbs and electric bills, I think it would pay for it self over time. Thats just my opinion.
