Measuring Light & Color On Your Schedule

Today’s lighting systems do more than just illuminate our surroundings. Light Emitting Diodes (LEDs), complex digital controls, and power electronics increase energy efficiency and customize output performance. Lighting systems must also endure constant exposure to harmful environmental and electromagnetic conditions without compromising photometric performance.

Elite’s powerful combination of EMCEnvironmentaland Photometric Testing services help lighting manufacturers successfully validate their products from every aspect with comprehensive testing to measure the magnitude, color, quality, and spatial distribution of light emitted from LED lamps and luminaires.

As a U.S. Federal Aviation Administration (FAA) Third-Party Certification Body for all product types covered by the FAA Airport Lighting Equipment Certification Program (ALECP), we can test and list your products quickly.

Elite is an approved laboratory for the DesignLights Consortium (DLC) product qualification program, providing IES LM-79 luminous flux and color measurements.

 

Complete Light Output and Color Evaluation

From aviation to automotive light testing, Elite’s photometric testing lab is fully equipped with state-of-the-art measurement equipment to make sure you get accurate and repeatable results on your schedule. Our lab offers broad measurement capabilities and ISO 17025 accreditation to meet FMVSS, SAE, FAA, ICAO, IES, MIL-STD and other common industry specifications as well as customer-defined requirements. 

In addition to steady light sources, we can accommodate flashing sources to measure Peak and Effective Intensity, Flash Energy, and Optical Power.

We can also design and build custom mounting fixtures to support lamps, luminaries, LED sources, and complete lighting systems while under test.

Light Measurements to Meet Your Needs

 

  • Photometry – Luminous Flux (lumens), Intensity (candela), Illuminance (lux, foot-candles), Luminance (candela/square meter, foot-lambert), Flash Energy (candela-seconds), Optical Power (candela-seconds/minute)
  • Radiometry - Radiant Flux (Watts), Intensity (Watts/sr), Irradiance (Watts/square meter), Radiance (Watts/square meter-sr), NVIS Radiance (NRa, NRb)
  • Colorimetry – CIE Chromaticity Coordinates, Correlated Color Temperature (CCT), Color Rendering Index (CRI), IES TM-30-15
  • Spectral – Flux (Watts/nm), Intensity (Watts/sr-nm), Irradiance/Radiance (Watts/square meter/nm), Peak & Dominant Wavelengths
  • Electrical – Efficacy (lumens/watt), Voltage, Current, Power, Power Factor, etc.

ISO 17025 Accredited for Automotive, Aviation, and LED Lighting
