no that wouldn't be enough light even with your t5's i don't think it would be enough for most corals....you might look at reefkoi's evolution leds even then you are looking at about probably $600 ...and of course there are also "better" options for leds out there....but you need to plan on buying some lights for corals because if your saying you have 1 -48" and 2-36" bulbs thats not enough either....there are some other options for used t5 and halide lights in the for sale section here you might look into but you have to factor in the cost of replacing bulbs and electricity usage ....in the long run leds are the least expensive option
