General Lighting
Photometrics


Photometrics is the term applied to the scientific measurement of luminesence at specific points around a target area, like a tenis court or parking lot. The goal is to make the luminesence as even as possible at the brightness desired, with a minimum of light spillage into adjacent areas outside the target zone.

Bieber Lighting uses precise tools to measure the luminesence of its various fixtures amd lamps. Below is a sampling of those results from some of our customers.



Horizontal Axis = Coefficient of Utilization
Vertical Axis = Distance Across Street / Mounting Height
