Measuring Light & Color On Your Schedule

military aircraft takeoff lightingToday’s lighting systems do more than just illuminate our surroundings. They include Light Emitting Diodes (LEDs), complex digital controls, and power electronics to increase energy efficiency and customize output performance. For many applications, lighting systems must endure constant exposure to harmful environmental and electromagnetic conditions without compromising photometric performance.

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

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 all-new photometric testing lab is fully equipped with state-of-the-art measurement equipment to ensure accurate, repeatable results and efficient operation. Our lab offers broad measurement capabilities and ISO 17025 accreditation to meet FMVSS, SAE, FAA, ICAO, IES and other common industry specifications as well as customer-defined requirements. 

In addition to steady light sources, we can accomodate 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, luminaires, 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.
