Reflector Considerations
Glare control and Lamp cut-off is important to consider when choosing how to illuminate an area. Our reflectors offer low aperture brightness at high angles to minimize discomfort glare.

Cut-off
Lamp cut-off is defined by the angle at which the lamp becomes visible. Our reflectors are designed to balance good lamp cut-off while maximizing lumen output creating high fixture efficiency.

The downlight in this example has a poor lamp cut-off angle and inferior reflector design, causing uncomfortable glare.
