Its a 4 bulb 30 fixture with two actinic and two 10k bulbs. Only three weeks old. Has built in timers and mounting legs. Asking $65 or trade for a slimmer or corals
The fixture is 30 long and 8 wide. The bulbs dont start until about 2 1/2 inches in on each side though and the legs are adjustable so this could work on a 24 tank if you did t mind the fixture itself stick out 2-3 on each side of the tank. Let me know what you think.
