In Aquarium Corals book (page 334) from Eric H. Borneman, he mention:

"It is rarely totally dark on coral reefs, and the light produced by a full moon in a clear tropical water is substantial enough for divers to see fairly clearly...The installation of a low-wattage blue or blue-white incandescent or actinic type bulbs may be a natural and aesthetically pleasant addition to lighting system. It is also likely to be quite beneficial to the health of corals, if only in normalizing diurnal patterns...."
