Lamp life
More than 50% of lamp population have light output > 50% of initial lumen
output after the specified lamp life time
Rise Time
Rise time to 80% of the stabilized luminous output is < 90 sec without forced convection. Extensive cooling of the
bulb during lamp run-up phase has to be avoided since it may extend rise time significantly.
Hot Restrike
If the unit has been off for more than 60 sec. The lamp must restrike. (Ignition voltage 16 kV +/- 4 kV)
No forced cooling is required following lamp switch-off.
