The Belgian lamp manufacturer VLUX uses translucent white colored Makrolon® 2207 from Covestro for the lamp covers in the Futurix series. The warm white material produces a pleasant room atmosphere with no glare.

LED luminaires from Belgian manufacturer VLUX have to be able to take a lot of punishment. The Futurix models were developed for use in damp and dusty environments such as parking garages and factory halls. They are also tough enough for outdoor use, able to withstand long exposure to wind and weather.

VLUX manufactures the energy-efficient luminaires from the high-performance polycarbonate Makrolon® from Covestro, formerly Bayer MaterialScience. The company has developed various grades of polycarbonate for lighting engineering applications.

The high-performance material is also used in the Futurix series of LED lamps. The Futurix models satisfy the requirements of the IP65 (IP stands for International Protection) safety classification and feature outstanding weather resistance thanks to the robust polycarbonate.

Tailored materials
VLUX uses translucent white colored Makrolon® 2207 for the lamp covers in the Futurix series. Covestro specially developed this diffuse grade of polycarbonate to meet the requirements for transmission and half-peak beam angle (HPA) while giving proper consideration to the required wall thickness and complex shape of the lamp cover. This is a warm white material that produces a pleasant room atmosphere with no glare.

Further advantages of Makrolon® 2207 are the material’s inherent flame retardance and high impact toughness. The thermoplastic material’s low shrinkage and low tendency to warp contribute to the dimensional stability and tightness of the luminaire construction. The polycarbonate thus protects the LED luminaires against the ingress of dust and low pressure jets of water from all directions.
