The Radion XR15 G6 Blue is EcoTech Marine's compact full-spectrum reef LED, tuned toward blue and actinic output with 395nm diodes for strong fluorescence. Its HEI2 optics widen output to about 126 degrees, up from 110.5 on the G5, and spread usable PAR across roughly four feet. It is fully programmable over wireless control with moonlight and weather simulation, and it accepts an optional diffuser and a wide range of mounts. Reef keepers pick it for color pop and app control; rivals like the AI Prime and Kessil A360X are smaller or simpler but offer less even spread and fewer spectral options.

Reef keepers rate the XR15 G6 Blue highly for color rendition, fluorescence and even spread, and many note the wider G6 optics cover more of the tank than the G5. Complaints center on the blue-forward spectrum and the cost of adding diffusers and mounts.
