Job Information Type:
To convert lighting data for a lower wattage incandescent lamp of the same type,
multiply the footcandle (or candlepower) values by the ratio of the lumens of the
two lamps. The coefficients of utilization remain the same.
Use quick calculator chart to determine the spacing of 100 Watt BR30 FL units for
a desired level of illumination. Conversion Factor: 75W A19, F.C. x 0.85. 1 Lt 13W
Quad Tube, F.C. x 0.6.
Spacing Ratio = 0.9
