All photometric data in this document was prepared using standard production fixtures, and the Prometric™ CCD measurement system.
Fixtures were adjusted for blending (cosine) distribution, and were tested with a calibrated lamp at its rated voltage. All data were normalized to nominal lamp lumens.
To determine illumination in footcandles or lux at any throw distance, divide candlepower by distance squared.
* (distance from origin) = (throw distance) x (throw distance multiplier)
