I just went to LED and I just did some reading on a 'KILL-A-WATT'.


LED: 2x60W

Start up Wattage: 46W each so a total of 92W
Running Wattage: 45W each so a total of 90W

Metal Halide: 2x250W (Im not sure if these are the electronic or magnetic ballasts.)

Start up Wattage: 165-175 each so a total of ~350W
Running Wattage: 280-281 each so a total of ~560W


Is it possible for the drivers to be outputting more light (suppose to be running 3Wx20 = 60watts of light) than how much electricty it is using (45w of electricity)..???

Either way... my tank looks happy and my electric bill and A/C (more electric) will love me a little more next month.
