light difusing and reflecting

Light Diffusing & Reflecting Materials

Luminaires are designed to assist with light control. Well designed light control may reduce glare, improve aesthetics, increase visual comfort, and allow for precise light distribution. Light Diffusing material and Light Reflecting materials are used to soften the look of high powered LED’s without reducing the efficiency.



Electromagnetic interference (EMI)/radio-frequency interference (RFI) is a disturbance that affects an electrical circuit that may interrupt, degrade, obstruct, or limit the effectiveness of the circuit. Devices that emit EMI/RFI require shielding to reduce the impact of the interference on other devices.
