Actinics light bulbs are a type of fluorescent or power compact light. The color of this light is very blue. Actinics are most useful to the chlorophyll in marine life, and they are the color of the sea below 10 meters. A little more costly than regular bulbs, but well worth the expense. Actinic bulbs are used in conjunction with daylight or "white" color bulbs to produce the proper color spectrum. Actinic bulbs show off the colors of the corals and fish in the tank by causing them to "glow" under the actinic light.
