BERTHA – Unique street lighting with large COBs

LEDiL introduces new BERTHA reflector family, a result of LEDiL’s collaboration with Bridgelux. It’s truly unique and patented free form reflector design provides good efficiency and control of light.
BERTHA comes in three versions optimized for street lighting with IESNA Type II short, Type III medium and Type IV medium type beam patterns. The reflectors are made from special heat resistant polymer and metallized using SiO2 process to take into account large amounts of heat produced by the high power COBs it’s intended to be used with.
BERTHA reflectors are designed for Bridgelux RS family of COBs putting out over 10 000 lumens. For many regulatory street classes this means that adequate lighting can be achieved using only one COB array.
