Where I can I get a 48in 4bulb t8 light fixture?

The oddysea would be ok if your planning some sort of hood/canopy where you can mount it say 6" above the tank, the reflectors are cheap so its not as efficient as a higher end fixture, the coralife one would be fine I think the fixture I have is the same thing just aqueon branded instead works ok but again the reflector is cheap its over my 29g and everything grows fine.
 
Yeah should be fine, I use the 30" version most of my plants are medium light, with one or two high lights, strictly chemical fert's no co2 and everythings doing ok.
 
I'm thinking either would work because even though the first is HO, it has an actinic bulb so it's not as bright as a dual fixture with two daylight bulbs.

Do you like the blue tint that an actinic bulb brings?
 
coralife should be fine.
it's t5no, so not much more than t8.
