has anybody had any issues with these bulbs burning corals not sure but is the uv supposed to be filterd out in the fixture glass im killin stuff?

Yeah but I don't think it was the bulbs just bad placement.
I melted a kenya putting it up high and bleached some sps's by not acclimating them slowly to the light.
I think I'm finally getting the acclimating routine down now.
Though LPS's seems to be fine no matter where I put them which Is strange to me.

If it's a double-ended bulb, which it should be, then yes, you need a UV glass shield between the water and the bulb.

I was under the impression that he was using the glass in the fixture and still killing corals.
