Evaluation of Lighting Parameters at the Workplace with the use Replacements for Incandescent Lamps

Abstract

The article evaluates the possibility of using halogen lamps, compact fluorescent lamps and LED lamps as direct substitutes of traditional 100 W incandescent lamps for selected residential lighting applications. A single halogen lamp, six compact fluorescent lamps and six LED light sources were examined. A traditional light bulb was also examined for comparison. All lamps operated in three luminaires. The basic evaluation criterion was the illuminance, uniformity and glare limitation in the place of work. It was found that not all light sources can be considered substitutes of traditional light bulbs. In the case of a luminaire made from a translucent material and one luminaire with a reflector, not all lamps allowed to obtain at least the same lighting parameters in the place where visual work was performed, as when a traditional light bulb was used.
