Additional comment about Costs, here in the Philly area Eclectic cost are about $0.17 a KWH, a 250w MH would be about $0.51 a day for a 12 hour day. So given that LEDs are at worst 10x more efficient that would be $0.051 a day. Which is $186.15 for 365 days vs $18.62 or a savings of $167.53 plus the LED’s should be good for at least 3-4 Years. So low TCO and less environmental Impact, I say they would be MUCH cheaper over a 3-4 year life. Just for tracking purposes what is a 250W MH setup worth? How much are the bulbs and how often do you change them?
I think we need to work up a TCO model for people to understand the advantages of LEDs not to say the low impact nature of LEDs.
TCO=Total Cost of Ownership
