Light measurement for product development and qualification

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 helps lighting manufacturers successfully validate their products from every aspect in one location.

Elite’s Photometry Laboratory is fully equipped with state-of-the-art measurement equipment to ensure accurate, repeatable results and efficient operation. Our lab offers broad measurement capabilities to meet SAE, FAA, 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. For general LED lighting applications, we can also perform IES LM-79 measurements using our Type A goniophotometer to simulate Type C geometry. We can also design and build custom mounting fixtures to support lamps, LED sources, and complete lighting systems while under test.

Light Measurements to Meet Your Needs

  • Photometry – Luminous Flux (lumens), Intensity (candela), Luminance (candela/square meter), Flash Energy (candela-seconds)
  • Colorimetry – Chromaticity Coordinates, Correlated Color Temperature (CCT), Color Rendering Index (CRI)
  • Spectral – Flux (Watts/nm), Intensity (Watts/sr-nm), Peak & Dominant Wavelengths
  • Electrical – Efficacy (lumens/watt), Voltage, Current, Power, Power Factor, etc.

Advanced Equipment for Trusted Results

  • Type A goniophotometer with 64 ft test distance (simulates Type C for accurate LM-79 measurements).
  • 2-meter integrating sphere with 4pi and 2pi geometries.
  • High-precision spectroradiometers with NIST-traceable calibrations.
  • Integrated power supply and analyzer with software control.
  • Custom mounting fixtures for every application.
