Description
From the sellerACTINIC (BLUE LUX – CORAL) T5 HIGH OUTPUT BULBS. Actinic radiation, typically centered around 420 nm (ranging from 400–500 nm), is critical for reef aquariums as it promotes coral growth, enhances fluorescence, and simulates the blue light that penetrates deep into ocean waters.
