• Faceted reflector with dichroic coating

• 95% of visible light transmitted through the optical
train

• 90% of infrared radiation (heat) passes through the
reflector

• Reflector and lenses secured with anti-vibration
shock mounts

• Low gate and beam temperature, shutters will not
warp or distort

Warning: Use of lamps other than HPL will void CE safety approval and

product warranty. Source Four Zoom is rated for 750W maximum.

Note: For illumination with any lamp, multiply the candlepower of a beam
spread by the Multiplying Factor (MF) shown for that lamp.

All photometric data in this document was prepared using standard production luminaires, and the Prometric™ measurement system. Luminaires were
adjusted for a flat field and were tested with calibrated HPL 750/230V 19,400 and HPL 750/240V 19,400 lumen lamps at their rated voltage. All data
normalised to nominal lamp lumens.

To determine illumination in footcandles or lux at any throw distance, divide candlepower by distance squared.
