cause scaling on the bulb?
The tank should have some kind of guard at least to prevent jumping fish. This could simply be a plastic light diffuser for drop ceilings (AKA egg crate). And the lamps separately may/will need some sort of UV lens. The topic is debatable regarding it’s impact on coral pigmentation. But the closer you are to the water, the more you will need that lens for several reasons… not the least of which is the hot bulb shattering if cool water should be splashed upon it.
