These are double ended. How would I tell if they have UV covers? Is it something the light fixture has built into it? I bought new bulbs last August. That might have been when I started having issues come to think of it.

I only run my lights for 4 hours a day and all the corals are at the bottom of the tank. Hammer and frogspawn are partially covered.
