Oh ok so it doesnt block the "dawn" bulbs and you hang it on after daylights go out. Thats always the trouble with T5 fixtures and moonlights/LED. Its tricky where to place them. Plan on doing anything permanent? Like mounting it how the reefbrites are with brackets?
yea, it's impossible to mount them under there permanently without them blocking out some light and heating up the metal strip.
if i were to do permanent moonlights, i'll mount them on the front bezel of the tank and them prop the 2 ends up so it'll be hitting my corals at an angle, which i might do when i have time. the light spread from that looks a lot better than hanging em.
the leds makes it look good but im sure its nicer in person. nice build btw. that does kinda suck you have to mount it on and off. but im sure you will find a way lol
