LSI is the only firm that not only operates an independent testing laboratory, but also manufactures testing equipment. LSI uses it’s own test equipment and has installed it in production areas and research laboratories around the world. Here are the products we manufacture.

NightMeter Light Trespass System

  • Measures luminaire intensity in candelas from an observation point.
  • Measures eye illuminance from a single luminaire or a selected group of luminaires.
  • Includes a digital rangefinder for distance measurements.
  • Designed to be portable.

High-Speed Mirror Goniophotometer

  • Provides unlimited capabilities in the photometry of lamps and luminaires.
  • Works extremely fast – typical indoor test takes less than 5 minutes.
  • Provides accurate results regardless of the lamp or luminaire beign tested.
  • Handles fluorescent, HID, LED and incandescent sources of any form of light distribution.
  • Can be used for research, development, product performance documentation and/or quality assurance.
  • Produces test reports in both IES and CIE formats.
  • The only way to test without affecting the output of position-sensitive lamps.

Automotive Goniometer

  • Uses WinGoni software including LampBook - a comprehensive international specification library containing hundreds of test specifications.
  • The operator simply selects the appropriate specification -- U.S. (FMVSS-108 or SAE), Japan (JIS), Europe (EEC) or U.N. (ECE). The selected file drives the goniometer, collects data and produces the desired report -- all automatically.
  • LampBook is updated annually to keep your laboratory up-to-date.

Integrating Spheres

  • Constructed according to technical specifications of IESNA, SAE and CIE.
  • Spheres available in 1, 2 and 3 meter diameters - the largest accommodates lamps up to 1.5 meters.
  • Test data produced by WinSphere® is compatible with standard computer spreadsheet software to allow further analysis and reporting and includes database capabilities.

AutoVidi Screen Photometer System

  • Alternative to traditional goniometer measurement systems.
  • CCD scientific digital video camera integrated in system to capture calibrated photometric readings.
  • Typical camera incorporates roughly 400,000 measurement points in a single frame.
  • Each pixel is calibrated traceable to NIST, providing outstanding resolution for high accuracy photometry.
  • Testing is performed almost instantaneously.

Lamp Life Test Stations

  • Tests all types of lamps for longevity under IESNA protocol.
  • Computer controlled – software monitors lamp and determines failure point.
  • Tests various lamp types simultaneously.

Lamp Base Torque Tester

  • Tests the strength of the base’s adhesion to the lamp.
  • Available for any size lamp.

Retro-Reflection Test System

  • Production-line quality control test system for 100% quality inspection at the point of manufacture.
  • Completely automated with Windows-based software and contains its own light source and photo detector.

Lamp Photometric System

  • Designed for photometric evaluation of lamps at close distances.
  • Compact and fully automated.
  • Operates similarly to our large mirror goniophotometers, collecting intensity data at all horizontal and vertical angles.
  • Available with a CCD video camera attachment to allow production of luminance maps of actual arc streams and filaments. This provides complete evaluation of a lamp's photometric characteristics.

Computerized Electrical Test Station

  • For quality control applications.
  • For production line performance verification of HID luminaires.
  • Tests a wide range of electrical parameters and automatically checks them against specifications.
  • Fast – just a few seconds per test · Can be used on high-speed production lines.
