Appendix B: Power and light output of HW-CFLs
NLPIP tested five self-ballasted high-wattage compact fluorescent lamps (HW-CFL) ranging from 55 W - 200 W with no luminaire enclosure. Total light output of each sample was measured in an integrating sphere. Each HW-CFL was measured base-up at approximately 77°F (25°C). While performing sphere testing, NLPIP collected data about power and color characteristics (see What are the color properties of HW-CFLs?). NLPIP also collected data about relative light output (see Short-term thermal effects section in How is performance affected by ambient temperature?).
