Sooooo Cree as in the LED manufacturer? Cree will make LED's look like hobby lights? :confused0059:
i meant hobby lights as in grow lights...as opposed to street lights. a 600w hps gives 150 lumens/watt although mostly in the yellow/orange range. cree's new cool white led put out 150-160 lumens/watt with a lot of blue (50% more than MH!). they're $25 a piece atm - so figure $3000 for 357 led - and that should drop to $12/led in 18 months (or less). i believe in 2-3 years we'll see 2-3 gram/watt efficiency - a 357 will be equal to a 1000w hps - at $700 per light. if the 357 is worth getting if it's equal to a 600 hps.
bigkuz grew out sensi star under a custom led from china...he even specifies the led ratios. i'd be super impressed if you got that quality AND the quantity (1.7 g/w).
