We are an independent, third-party testing laboratory specializing in spectroradiometric and photometric testing, including measurements of Solid State Lighting (SSL) fixtures and single and array LED devices.
Our light measurement services include, but are not limited to light output (a.k.a. total flux, lumen output, power, intensity, brightness, etc.), color characteristics (correlated color temperature, color rendering index, CIE chromaticity coordinates), illuminance, irradiance (including PAR irradiance), and others.

Industries served:
· Lighting manufacturers - solid-state lighting, luminaires, floodlights
· Automotive lighting - headlamps, gauges
· Highway safety - traffic control devices, LED signs
· LED manufacturers, research and development
· Academic research
· Architectural and interior design
At LightTest Labs, we never use photometric filters. All measurements are spectral, which is especially critical for “peaky” light sources, such as LEDs/SSL or fluorescent bulbs.
