automotive HID lights vs. cfl's
Actually using a computer power supply. you only need a 10 amp one to run two lights. the power supply only draws an extra 10 watts for a total of 80 watts!! i measured the current draw so this is real time power consumption. I'm not sure if this is patentable. To get one cost big$$. I want to build these in a turn key package with reflectors, bulbs, ballast, power supply and even adding a few large cfl's for veg stage and of course cooling fans.

I just got my quantum light meter back from repair. This meter measures PAR light. It doesn't tell you what color spectrum whether it is blue or red but it tells you par light reading. With this meter, i measured the par output of these and found why they are working so well. My readings are at the top of the canopy and it is at a peak of 1800 uMol/s and average of 500uMol/S even down low!! the cfl's had a more even reading all over at 300 and much less as you move down. These readings are what you expect from a 1000 watt HPS! all be it a smaller area. The most amazing thing is that the readings from the HID are 18 inches away from the bulb wereas the reading from the cfl's were done at about 8 inches and faded rapidly as you moved further away so the reflector is doing an awsome job not only at ligt distribution but also heat is not an issue at this distance. Remember my cfl set up is 355 watts the hid's are 80!!
