so I'm following a demolition job at work and I run across this... they actually had 2 but i only got one. took it apart and made the canopy for the lights for my 400 gallon build. I'll be doing all T5. this fixture as you see it had no ballasts but ( 8 ) 400 watt high pressure sodium bulbs.... 3200 watts! and the area was only about 10 square feet!!! I can't imagine what NASA used that for. I think that would light a reef tank pretty well. mogul bases about to be listed in for sale section
