Been a long time sence we had a lighting fact thread

Hi,

Okay,

200-250 uE/(m^2*s) @ 12" - 6" air and 6" water

The numbers are really for information purposes since some reefers were interested in the numbers. The numbers vary because of my actinics -- they are mounted at the centre of the canopy and surrounded by two 6500K T8s. Since my PAR meter has less sensitivity with blue light, the PAR numbers have a double peak as I sweep my sensor from the front of the tank to the back of the tank.

Honestly, I didn't think my lamps would compare to a 2x 430W HQI. Keep in mind that although the lamps produce 1/3 of the Stircrazy's measured output, the lamps burn less than 1/3 of 860W. On the other hand, I am sure the specturm is much better on the HQI -- especially the blue bands.
