Introduction
The Spectra Candela III Traffic Signal Light Tester measures luminous intensity and light output degradation of Red, Yellow and Green LED signal modules in order to meet mandated minimum safety standards.
Spectra Candela III Traffic Signal Light Tester Model 2000 is a versatile, precision, portable multiple channel Photometer/Radiometer. Its’ specifically Custom Configuration allows unit for measuring luminous intensity, illuminance, luminance, irradiance, radiance, radiant energy, and many other special parameters. Specifically configured calibrated channels can also be used to measure luminous intensity [Candlepower in candelas (Cd)] of Red, Yellow, and green LED traffic signal modules and Photometric brightness Red, Yellow and Green Arrows (foot-lamberts/cd/m2). Calibration and indication of the proper readout unit is accomplished automatically when the switches are set and the proper accessories/attachments are installed.
The TSL tester can measure luminous intensity of LED signal modules and photometric brightness of LED signal arrows. The measuring capability and sensitivity range of the instrument is given in Instrument Specifications.

The transportation industry demands a portable, calibrated light meter (photometer) for field measurement of light output degradation of Light Emitting Diode (LED) traffic signal light emission.
There are number of inherent problems with LEDs. One critical issue is degradation. Instead of burning out catastrophically, like the incandescent lamps they replace, LED lamp light output continuously degrades (dims) as a function of time and temperature. Rarely does an LED lamp exhibit complete burnout. As an example, the subtle, continuous decrease in light output of a red stoplight eventually results in impaired visibility, leading to a potential traffic safety hazard.
Responding to industry requests, the Company introduced a Traffic Signal Light (TSL) field tester and currently has more than 300 systems in the field, including several units approved and purchased by California Department of Transportation (Caltrans) and other municipalities and states.
