EcoTech Radion XR15 G6 Blue vs AquaIllumination Prime 16HD
The Radion XR15 G6 Blue is the stronger light: about 100 W, 10 color channels, deeper UV diodes and a proven track record on coral color and growth. The AI Prime 16HD is the smaller, lighter fixture at roughly 55 W, and it is the sensible pick for nano and small tanks where one unit covers the footprint. Both use app control with no separate controller, but the Radion gives more headroom and more tuning for demanding SPS tanks. Owners of both report long service life; the Radion's larger heatsink and fan make it the more robust build.
- Choose the Radion XR15 G6 Blue if you keep a deeper or SPS-heavy tank, want maximum output and UV reach, and already use or plan to use Radion mounting.
- Choose the AI Prime 16HD if you have a nano or small tank, want a slim light with a long cord, and need full programmability without extra hardware.
