For illumination with any lamp, multiply the candlepower of a beam spread by the
multiplying factor (mf) shown for that lamp.
To determine illumination in footcandles or lux at any throw distance, divide
candlepower by distance squared.
For Field diameter at any distance, multiply distance by .63
For Beam diameter at any distance, multiply distance by .45
Metric Conversions:
For Meters multiply feet by .3048
For Lux multiply footcandles by 10.76

All photometric data in this document was prepared using standard production
fixtures, and the Prometric CCD measurement system. Fixtures were adjusted for
cosine distribution, and were tested with a calibrated HPL 750/115V 21,900 lumens
lamp at its rated voltage. All data were normalized to nominal lamp lumens.
