Independent Testing Laboratories

What Independent Testing Laboratories does

Independent Testing Laboratories (ITL Boulder) is a US-based provider of photometric testing equipment and laboratory services serving the lighting industry. Founded in 1955 and headquartered in the Boulder, Colorado area, the company designs and builds precision light measurement instrumentation — most notably Type C (mirror) and Type A goniophotometers used to characterize the spatial light distribution of luminaires and lamps — alongside photometers, spectroradiometers, integrating spheres, camera-based and far-field photometry systems, vibration test machines, and specialized Adaptive Driving Beam (ADB) automotive lighting data acquisition systems. Its portfolio also includes custom equipment builds and proprietary control/software for instrument operation.

The company generates revenue through two primary channels: B2B sales of new equipment and aftermarket support/upgrade services for an installed base of legacy UL/LSI goniophotometer models (AP-G6440, AP-G6420, AP-6220), plus contracted laboratory testing services performed at its Boulder facility. Pricing is quote-based and not publicly disclosed; sales are conducted via direct enterprise engagement through the corporate website. The customer base comprises lighting manufacturers requiring photometric certification and compliance testing and independent testing laboratories that purchase measurement equipment.

Since May 2023, ITL has operated as a subsidiary of Sapphire Technical Solutions (STS), which acquired the company to consolidate its photometric equipment and laboratory capabilities. Under STS ownership the product lineup has broadened to include camera-based and far-field photometry, Type A goniophotometers, and ADB automotive test data acquisition, indicating a deliberate expansion of addressable surface beyond traditional luminaire testing. Geographic reach is limited to North America (USA), and the company maintains a small workforce (11-50 employees), making it a focused specialist rather than a diversified instrument vendor.

Core offering

Independent Testing Laboratories designs, manufactures, sells, and services photometric and light measurement equipment — most notably Type C mirror goniophotometers and Type A goniophotometers — along with photometers, spectroradiometers, integrating spheres, vibration test machines, and proprietary control software. The company also operates a photometric testing laboratory that performs contract measurement services for lighting manufacturers and supports or upgrades legacy UL and LSI goniophotometers in the field.

Product overview

Sapphire Technical Solutions (STS) offers a comprehensive portfolio of photometric testing and measurement equipment, acquired alongside Independent Testing Laboratories (ITL Boulder) in May 2023. The product line centers on goniophotometers (Type A and Type C/mirror configurations) as core measurement instruments for characterizing light distribution patterns. Complementary products include photometers, spectroradiometers, integrating spheres, camera-based and far-field photometry systems, light sources, and vibration test machines. The portfolio also encompasses software solutions for test data acquisition and analysis, custom equipment fabrication, and dedicated services for Adaptive Driving Beam (ADB) automotive lighting testing. Additionally, STS provides support and upgrade services for UL/LSI goniophotometer models (AP-G6440, AP-G6420, AP-6220). Laboratory testing services are offered through the ITL Boulder facility acquired in 2023.
