T5 bulbs

[RayAnthony]

Hello again! I have what I think is a 30 inch t5 with 4 bulbs. What color spectrum bulbs would be recommended for a 40 gallon breeder reef? I don't think I want any sps corals jtlyk. I tried to take a picture of the 2 bulbs that aren't burnt out. I don't know what spectrum they are but they look blueish purple in the middle. I have no idea how many hours are on them
