FYI That
HQI reflector housing is much smaller than the reflector I got with the 175W SE bulbs I just got from hellolights. Maybe not lengthwise but the open reflector might be almost twice as wide. But the light is awesome and it is better reflector
IMO because it has the dip in the middle (forget what thats called) and multiple angles to really reflect all the light into the tank. I also got the cheap magnetic
ballast and it is heavy but not in a housing so not all that big. I was planning to mount it on the rear of my canopy. But if I like the lights I think I may upgrade to electronic at some point. The magnetic hums a little but definitely not too loudly.
