What is Unified Glare Rating?
BACK TO FAQS
Unified Glare Rating, also known as UGR, is used to measure how much glare is emitted from luminaires (an electric light unit). It is used in the workplace to determine whether glares will cause discomfort to individuals exposed to the luminaire, particularly in settings where staff work on computer monitors. Failing to consider the UGR of lights can impact the well-being of your workforce, causing vision fatigue or nausea, for example.
