Hemispherical Edge Illumination
Generation 4 includes the most sophisticated lens design available. HEI lenses deliver the light uniformity and color mixing of halide T5 combo without sacrificing the power and efficiency of the LEDs.
How impressive is the new HEI lens design? Just compare the previous generations of Radion lenses, which utilized the best optical technologies of the time. Observing the respective PAR distribution of the reflector and TIR lenses, it is immediately apparent that HEI Optics offer a significant improvement from the perspective of providing usable coverage.
QUIET ACTIVE COOLING
The G4 heat sink has been designed from the ground up to maximize surface area and allow for superior heat dispersion. Multiple channels provide unrestricted airflow. This effective heat management greatly reduces the need for active cooling, which decreases fan and airflow noise.
