Cree Services provide a comprehensive suite of Thermal, Electrical, Mechanical, Photometric and Optical tests (TEMPO) for LED luminaires.

TEMPO delivers the accumulated advantage of Cree's LED system knowledge and include important tests that are not available elsewhere, such as binning and color point evaluation, chemical compatibility and TM-21 lifetime projection.

TEMPO measurements are performed at Cree Technology Centers worldwide on equipment with calibrations that are traceable to NIST. Cree Durham Technology Center (NVLAP lab code 500070-0) is accredited by The National Voluntary Laboratory Accreditation Program (NVLAP) to satisfy the requirements of ISO/IEC 17025:2005, IES LM-79-08 and LM 58-94.

TEMPO  

TEMPO 24 provides the most comprehensive LED luminaire testing available, including LM-79 photometric tests as well as other important tests that go beyond LM-79 to ensure total system quality. Not offered anywhere else, these rigorous tests include binning and color point evaluation, electrolytic capacitor assessment, chemical compatibility, TM-21 lifetime projection, dimmer compatibility and Lighting Facts assessment. This also includes a one hour consultation with a Cree Application Engineer.

TEMPO SPOT provides you with three quick turn-around service options to validate the design of your prototype.

Option A: Photometric test on a two-meter integrating sphere using the 4π geometry method that provides measurements of luminous flux, radiant flux, spectral power distribution, CCT, CRI, color coordinates (CIE 1931 and CIE 1976) and luminaire efficacy (lm/W).

Option B: Photometric test on a type-C goniophotometer that provides measurements of total luminous flux, luminous intensity distribution, maximum candela, maximum candela angle, and luminaire efficacy (lm/W). Measured data is presented in IES, EULUMDAT or CIBSE file formats.

Thermal: Quick validation of solder and junction point temperatures. Spot thermal provides solder point temperature, thermal imaging of your luminaire at steady state as well as an extrapolation of the junction temperature.
