I finally got my paws on a PAR meter, so I figured I'd take some measurements of what PAR my new lights are putting out over my frag tank. My frag tank is 12" deep, but I couldn't exactly get the sensor down on the bottom. So I took the PAR measurements at 0", 6" and 10" (0" being right under the water level). My lights have 72 white LEDs and 108 blue LEDs. The LEDs are 3-watters, but they are pushing 1-1/2 watts apiece. The reason for the lower wattage is to control the temperature so it doesn't overheat and the lights will last the full 50,000 hours.
