Great post Nick and I was just kidding about missing the original link ....... couldn't resist. Thanks for the links Boomer. Very interesting reading. According to the manufacturer this unit is a no-brainer for about 11 years (if I read correctly). All things considered for eleven years (MH replacement bulbs, ballasts, timers, dimmers, daylight simulation units, chillers, electricity bills, ..) it's really not a bad deal. There must be some substance to this product because given its healthy price tag it's already sold out for 4-6 weeks. Very interesting indeed.
