^^ very true what gglmao said, to be honest I like a combo of led and t5 which is a hybrid, best of both worlds, great colour with the pop that led brings.
Having said that I would probally do a custom system as the prebuilt ones are abit expensive.

You have to do more research to find your answer. If you run mh it could heat up your tank faster especially on those warmer days, unless you keep the AC on all the time or have a basement.

I have to say trying all 3 I like the t5 the most for colour.
Used t5 fixtures are cheap and when ordering bulbs online very inexpensive. I run 3 t5 fixtures ATM 2 8 bulb 4', and 1 4 bulb 3'.
Lights per year runs me about $440 but I change my bulbs every 16months so not that bad.
