I have two tanks both 75 gal 48' tanks, both coral. t5 light burned out. i have a awesome light still working but needs bulbs. so im wanting to go to a led tank but do not want to spend over 400.00 on led. so my question is what led light would would fit my value and requirement for my corals. or do i need to buy a t5 light to replace the burned out, and replace bulbs it the other on, it a currant usa 2x 250mh 4 t5. thanks for any suggestions
