Help with T5 lighting

[Magede]

I currently have a T8 blue light (dono whats the specs) and I'm thinking of adding a T5 light for my tank. Went down to the LFS today and they said T5 is somewhat different from T8. Just wondering where can I get the connecting pins for T5 lighting and whether I should just add 1 more T8 instead.

Currently running a FOWLR tank of about 4ft x 2ft x 2ft. Hope some experts out thr can advice

actually if you're doing a FOWLR, lights is only for aesthetic purposes only.

the fishes don't need the lights and a simple source of illumination is required.

yes, if u r going into corals, T5 is good to have. but still it depends on what kind of corals u planning to keep
