Press Release Summary:

January 13, 2009 - Available in 400 and 1,000 lumen models, Forward Flux Lamp Standards can be used to calibrate integrating sphere spectrometers for total forward spectral radiant flux responsivity from 350-1,050 nm. Each lamp standard is seasoned for 1% of rated life, and then screened for stability and repeatable performance, before transferring lumen directly from NIST lumen reference. Standards include calibration certificate and calibration data on CD-ROM.

Original Press Release

Industry First Forward Flux Lamp Standards for Light Measurement System Calibration

Press release date: December 17, 2008

The most accurate NIST-traceable calibration available

North Sutton, New Hampshire (December 17, 2008) - Manufacturers of LEDs, light fixtures and displays can now calibrate their spectral or luminous flux measurement systems quickly and accurately with Forward Flux Lamp Standards from Labsphere. This entirely new technology, available only from Labsphere, provides an exceptional artifact for maintaining and verifying 2Π integrating sphere spectrometer calibration with a highly reliable standard calibrated directly to the National Institute of Standards and Technology (NIST) lumen.

Available in 400 and 1000 lumen models, Forward Flux Lamp Standards can be used to calibrate integrating sphere spectrometers for total forward spectral radiant flux responsivity from 350 nm to 1050 nm. The lamp standards are designed to meet the recommended practices of the Engineering Society of North America (IESNA) LM-79 for 2Π measurements of solid state lighting.

Each lamp standard is carefully seasoned, screened, and calibrated. All lamp standards are first seasoned for 1% of their rated life, and then screened for stability and repeatable performance, before transferring the lumen directly from a NIST lumen reference. The result is an accurate and reliable system calibration with a lamp standard distribution similar to the light sources being tested.

Lamp standards include a calibration certificate and calibration data on CD-ROM. Labsphere is an ISO 9001: 2000 Certified company.
