Benefits

UL is a market leader in the lighting industry. We have 30 years of experience testing indoor, outdoor, aviation, automotive and solid-state lighting (SSL) products. Our team of experts works with the U.S. Department of Energy, Natural Resources Canada and other energy efficiency institutions around the world.

We provide independent product performance testing needed to demonstrate compliance with international standards using data from an independent, objective source. And UL offers fast turnarounds, completing most photometric tests within 10 business days.

UL’s compliance reports adhere to the standard formats required by IESNA and the International Commission on Illumination (CIE). Our reports can also be customized to meet customer specifications. Photometric characteristics are provided in easily compared file formats for demonstrating the commercial viability of lighting products.

As a leading producer of photometric equipment, including goniophotometers, lamp life test stations and screen photometric systems, many of UL’s photometric testing services utilize equipment that we design and manufacture, giving our customers access to the most sophisticated photometric testing innovations.

Members of our team are pioneers in the LED testing industry, and active members of standards development organizations, enabling us to provide our customers with much more than raw testing data. We help lighting manufacturers leverage their UL testing to understand customer performance expectations, clarify competing product claims and better understand international testing requirements.
