T5 or led is better

[happyguy1682]

I wan to use on a 4,2,2 tank.... Which light should i buy ??

Anyone can upadte me more.... Which 1 is more effective

LED is more cost effective in the long run due to savings in electricity cost, longer lasting and lower heat dissipation, but it has a higher startup cost.

Both are equally effective in getting the right lighting for your corals when used at the correct illuminance.

bcos i c the led light is blue n white cost me 145@ 4ft... n i'm planning to get 2 of them is it to powerful ??

It depends on the illuminance provided by the light, different brands/models have different specifications, the number of diodes and power difference of diodes. It's hard to tell just by the cost
