News, Lighting Essentials

Coral fluorescence results from proteins in the coral animal that absorb shorter-wavelength light and emit longer-wavelength colors, distinct from the coral’s symbiotic algae.

GHL’s Mitras LX8 fixture offers twelve adjustable channels spanning near-UV to Hyperred, enabling tailored lighting to both highlight fluorescence and support coral growth.
