the 150w ufo's draw about 45-50w at the wall
LED for the most part is a lie
what I mean by that is that they will claim
500w of power
what they are really saying is
the 150w led MAY be equivilant to 500w of incadescent
and all leds are not made the same as is the case with hps for the most part
with hps you can pretty much throw in any 600 and know what to expect
with LED it is a differ story
the LED's that I run are true 75w a piece actual 3500k spectrum
a total of 300w of actual draw = 150 par watts which is pretty equivalent to a 600w
Gavita
I am outputting 48,000 lumens with 300w
it has been measured at 950ppfd in a 2x4 space @18" above canopy
I pulled of 300g off my last run with 300w of light
with those blurple type single diode leds you have to get like 4" to the plant because of the reverse square law principle
sorry rambling
but yeah 50w per ufo
