HQI bulbs

[StirCrazy]

the new iwasaki was rated at 173 so suposing 50 to 70% increase for a reflector that takes it to
259 to 294, the 150 HQI was 246, but if we realy want to compare in the same colour temp (10000K)the best that they got was 90.06 with the 400 watt MH bulbs. so when you add the 50 to 70% to that you get 135.09 to 153.15, so you can see that the 150 HQI blows a 400watt MH of the same colour out of the water using only just over 1/3rd the power.
