I want to replace it with 3 x 16 watt LED flood light with 6500 Kelvin each. Is that good enough for tank?
Going by Rapidled's calculator for plants tanks you will need tanks footprint divided by 25 i.e 48x18/25= 34.56 Led. ( Their calculation is based on Cree Led ). For Led's like edison, exiled I guess you will require twice that number.

Nothing, but I assume this should hold good till 18".
