Deep-Red & Far-Red

Deep-red and far-red LEDs are recommended if you are conducting a natural species behaviour study. Many deep-sea creatures are unable to see in the red spectrum and using a red LED allows researchers to view biota in their natural behavior. Read more tips to pick the best deep-sea lights.

Deep-Blue

The deep-blue LED was designed for underwater biofluorescence and leak detection. Fluorescent chemicals absorb energy from light and then emit a different colour of light. Bio-fluorescence is the absorption and reemission of light from living organisms. Read more in our Guide to Subsea Lighting.
