The German-made Radium 20000K metal halide bulb offers excellent coloration and good intensity. It is crisp-white with a strong blue tint.
It brings out the fluorescent pigments in corals nicely. Fluorescent supplementation is usually not necessary, but can be used for added intensity and to simulate dawn and dusk.

Radiums are the only way to go
Title says it all. I love Radium bulbs and Ill never buy anything else. These bulbs will make your coral glow!! I notice way better color with Radium bulbs compared to any other bulbs. Their a little pricey but your coral will thank you for it.
