lo0king to add mroe lighting to my tank! 75gal
currently loking at T5s,

I can get a 2x54 bulb retrofit where each bulb has its own reflector.

OR

a 4x54 bulb fixture where its all under 1 relector.

Which one would be better? Does each light having its own reflector compare at all to a 4 bulb fixture?

Also, anyone got the lead on a place to pick up a retrofit for cheap? Tanks in advance.
