About The Lab

The LIA Laboratory has a 30-year history in lighting product testing. In 2016, we opened our state-of-the-art, 12,500 sq ft facility, thanks to the support of LIA Members and The LIA Council.

We are dedicated to pioneering technological advancements. By continually investing in the latest equipment and rigorous staff training, we ensure exceptional service quality.
