The Proten LED Reef Blue is a 36 W actinic-blue LED striplight in an aluminum housing, sized for 48-inch aquariums. It is built to add the blue spectrum that reef keepers use for coral fluorescence and dusk/dawn viewing, not as a full-spectrum growth light on its own. Compared with multi-channel reef fixtures, it is a single-purpose strip with no dimming or program control, so it suits simple setups and supplementing an existing white light. Reef keepers generally treat blue actinic strips as a mood and fluorescence tool rather than a primary light source.
