Abstract

By controlling the lamp wall temperature of fluorescent lamps with a Peltier device, the optical efficiency of luminaires can be measured directly. Measurements of the fixture efficiency for a luminaire can vary by over 8% depending upon the lamp-ballast system used in the measurement. The authors suggest that optical efficiency may besan improved metric for evaluating fixture designs.
