Default New lighting tests. Interesting resutls. as per usual.

Hi,

Hmm...the spectral results are up and I guess the SE lamps have quite a bit of energy in the greeen/yellow bands. So, the useful reefPAR is actually not dramatically different from the 150W DE bulbs and the other SE bulbs. Anyway...looks cool.

FYI...I don't think a MH is a point source at 3.5". This is because the MH ARC is about 1 to 3". So, your point source extrapolated numbers while be pestimestic (i.e. lower than actual). For a more accurate calculation, you would need some calculus and an integral.
