Measurement of actual efficacy of compact fluorescent lamps (CFLs)
Highlights Energy used by lighting contributes a large share of energy use in the building sector. Compact fluorescent lamps have higher energy efficiency and longer life expectancy. Measurement of actual efficacy of compact fluorescent lamps had been conducted. Energy information provided by lighting manufacturers is reasonably conservative.
Abstract The use of compact fluorescent lamps (CFLs) in domestic residences has increased rapidly due to their higher energy efficiency and longer life expectancy when compared with traditional incandescent light bulbs. Through measurement of illuminance, actual power and apparent power, the actual efficacy and associated power factor of CFLs are studied in this paper. It is found that for an individual CFL, although its power consumption and lighting output (i.e. luminous flux) may be higher or lower than the stated values provided by the lighting manufacturers, the actual efficacy would most likely be equal to or better than the efficacy calculated from the given rated power and lumen from the manufacturers. The typical power factor for CFLs was 0.63.
