Possibilities for polycarbonate reflected in Lumenova™ lamps

Spotlight on innovative commercial lighting design

Commercial and hospitality spaces want to appear warm and inviting to consumers. A light and bright atmosphere helps to convey this, but excessive lighting can increase energy bills.

Lumenova™ reflector lamps
Reflective white Makrolon® RW6267X polycarbonate from Covestro helps Lumenova™ achieve high lumen output for its LED reflector lamps.


Lumenova™, a CRS Electronics Company, set out to design a replacement solution for previously used, inefficient incandescent lamps. Lumenova’s™ goal was to develop an energy and cost efficient product to help commercial and hospitality customers create bright spaces for stores, lobbies and offices.


For the Lumenova™ R20, BR40 and BR30 reflector lamps’ optical mixing chamber (the area between the internal LED and outer lens) Lumenova™ desired a material that offered long-term reliability, widespread availability and high-performance properties to produce the highest efficiency and lumen output.


Because of its availability and high reflectivity, Lumenova™ decided to replace the original material chosen for the LED reflector lamps with Makrolon® RW6267X polycarbonate. This grade can be injection molded, which imparts greater functionality without the secondary operations associated with a metal part.
