illumia® Plus2 elevated temperature spectroradiometers include a choice of a 1.65 m or 2 m insulated integrating sphere with temperature-controlled feedback loop, application-specific modules, accredited reference lamps and Integral® Software.

Measure with Confidence
When a solid-state light engine is used in a luminaire or fixture, the thermal environment near the LEDs are altered by both the design and the application environment. By measuring the performance characteristics of a luminaire or fixture at various temperatures, one can model the expected light output by measuring the operating temperature. Labsphere’s illumiaPlus2 elevated temperature integrating sphere spectroradiometers enable you to characterize the thermal behavior of your luminaire or fixture simply and confidently across a temperature range of 15C to 80C.

Automated Thermal, Optical, and Electrical Characterization
Integral® software allows users to measure the optical and thermal characteristics of various luminaire or fixtures quickly, accurately, and simultaneously. Each illumiaPlus2 elevated temperature integrating sphere spectroradiometer includes a fully integrated Cincinnati Sub-Zero ZPRCS-1816-6-SC/AC Z Plus Remote Conditioner for temperature control and monitoring. Increase confidence in your fixtures and luminaires while increasing testing efficiency with built-in IES LM-79 -19 and S025 stabilization routines, compliance with IES LM-79 -19, IES LM-78, LM-82 and equivalent measurements, and real- time LIVT sweeping.
Specifications
If you need top of the line performance in lamp and luminaire temperature characterization, there’s an illumiaPlus2 elevated temperature integrating sphere spectroradiometer for you.
