Who is ITL Boulder?

Independent Testing Laboratories, Inc., founded in 1955, was one of the first independent light testing laboratories in the country. We provide lighting manufacturers, specifiers, designers, architects, the government and others an accurate, efficient and unbiased source of evaluation for virtually every type of lighting.

As of August 6, 2021, ITL closed the testing services portion of our business to concentrate on our lighting test equipment business.

ITL’s main focus has always been on testing. This has given us the opportunity to learn a lot about our clients and what they need. We have used that information to create lighting test equipment (goniophotometers and integrating sphere test systems) that are simply unmatched.
