Conversion Factor: 75W PAR30 FL; White, C.U. x 1.1 65W BR30
FL; Black, C.U. x .75; White, C.U. x 1.0.
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.
