Present day fluorescent lighting efficacies have been improved by phosphor technology that emits light in the red,blue and green portions of the visible spectrum. These new phosphors can withstand higher power loading and exhibit less depreciation over time compared to standard colour halophospates. This would indicate that the thermal characteristics of the lamp and luminaire system are favourable. 1 High frequency electronic ballast for 1 to 4 T8 lamps. This ballast is an instant start design, used in this system with 2 F032 T8 high efficiency lamps.
Fluorescent lamps become more efficient when supplied with high frequency power.
F032 T8 high efficiency lamps are primarily rapid start designs, requiring cathode heating for electron emission purposes. The tested system had two F032 T8 lamps installed. High efficiency low loss magnetic ballast fitted with 2 high lumen 40-watt T10 high efficiency lamps. This high efficiency ballast is modified to enhance lamp performance and includes an energy saving core to reduce ballast energy losses. The summarized results for the performance of all 7 systems are presented in Table 1.
