BEGA Hybrid Optics ®

BEGA Hybrid Optics ® offers complete lighting control thanks to optimum refraction and reflection. Precisely calculated reflectors with a surface made of pure aluminium and lenses made of ultra-clear silicone or glass capture nearly every beam of light from the

LED modules. The interplay between lens and reflector technologies achieves maximum application efficiency.
