Radion G6 increases output from an impressive 110.5 degrees in the G5 to a staggering 126.3 degrees.
This improvement was achievable through a change to the primary optic on the LEDs which then integrates with the geometry in the existing HEI (Hemispherically Edge Illuminating) secondary optic (lens).
Hemispherical Edge Illumination
Radion is a winner in the cost vs. output equation. The HEI2 optical system delivers 126.3 degrees of output. The result, incredibly even PAR over almost 4ft of coverage area making it the highest average output Radion and perhaps the most efficient aquarium light ever made.
