Calculation Data Total Lamp Lumen / Circuit Power
Initial lumens are based on 100-hour measurements. Efficacy is calculated by dividing the 100-hour lumen output by the rated lamp power. Control gear losses are not taken into
account. E.g. 13w TC-D 900 ÷ 13 = 69 lm/w. For reflector lamps efficacy PAR lamps, use the equivalent rated non-reflector variant e.g. PAR 38 100w use A 60 (GLS) 100w, PAR 30
75w use QT32 75w and CDM-R 35w use CMI/CDM-TC 35w. Circuit power is shown for both magnetic (Cu/fe) and electronic ballasts (HF) where applicable - circuit watts for
magnetic ballasts are shown in brackets. Data sources; CELMA, GE, Osram, Philips and Sylvania.
