Hey I am seriously considering this 24' hybrid, but I've got a problem with the dimensions. My tank (IM Mini 38) is 24' long, 19' wide (and since it's AIO tank, the display tank is only 15' wide, with the rest 4' being back chambers). I know the light fixture is 20' wide. So how do I fit it if I want to use it? I am afraid there will be a lot of light bleeding out either from the front or too much light thrown into the back chamber section. Can I just skip installing the 2 T5 bulbs in the back and only use the 2 T5s in the front plus the LED? Also it doesn't really sounds like an ideal solution ...
The 24" fixture comes with standard 18" wide end plates. The actual T5 bulbs are in-set 1-3/4 from the front and rear of the fixture profiles, so with 18" plates the actual lighting area would be 14.5" wide. With the optional smaller 16" plates, the T5 lighting area would be 12.5" wide. There are currently no 20" wide spacing plates, only 16, 18 (default) and 24".
