I have two reflector sets with two sockets each. Both were running 250 watt bulbs per socket but could go 150-400 depending on the ballast. 4’x2’ roughly. I ran lumilite LEDs on the long edges but they could have t5’s if you wanted to get creative. Pictured is the one I had the LEDs on. No ballasts, no bulbs, and you’ll need to wire the plugs depending on your ballast choice. I had these over a standard 120 gallon with the bulbs about 12” off the water with 14k bulbs and they were awesome. I upgraded fixtures this weekend so these are ready to go. Second set not pictured but it’s similar. They might be old lumibrite reflectors.
