The Science Behind Coral Fluorescence: Understanding the “Wide-Band-Blue”

Corals glow because fluorescent proteins re-emit absorbed light at longer wavelengths, while chromoproteins add color by reflection. GHL’s “Wide-Band-Blue” spectrum (390–510 nm) excites the cyan and green proteins behind most of the fluorescence; additional channels reach toward violet and red for the rest of the palette — adjustable across the Mitras LX luminaires.
