PHOTOMETRICS
Photometric data below is measured with an HPL 750W/115V 300 hr lamp. To convert data when using any other HPL lamp, use the lumen or
candela multiplying factors (Lm MF or Cd MF) for that specific lamp. These multiplying factors are listed in the Lamps table in this datasheet. For
lumen data, multiply by the Lm MF. For candela or footcandle data, multiply by the Cd MF.
