Actinic Aquarium Lighting
Blue light travels further in water than other wavelengths. Actinic lighting fixtures, ideal for saltwater tanks, produce only the blue end of the spectrum, which is perfect for deep water fishes and invertebrates, and fishes that don't like bright light (such as cichlids). Actinic lighting fixtures promote coral growth and proper photosynthesis in symbiotic algae that corals need to thrive.
Actinic fixtures either use 50/50 bulbs, which produce 50% actinic light and 50% white daylight, or a combination of actinic blue bulbs and daylight bulbs for more intensity in deep tanks. Actinic fixtures come in all intensities - fluorescent, compact fluorescent, and metal halide. We also have fixtures that include lunar LEDs, or you can add a lunar light for a complete day/night cycle.
