Turning the Lamp Off
Turn the Xenon lamp off by holding the Xenon ON/OFF switch down for one full second. The Status
LED blinks for about 30 seconds while the lamp cools down.
Warming Up the Lamp
The HPX-2000 requires 25-30 minutes of operation to reach a state of thermal equilibrium. During this
warm-up period, the intensity of the output power can vary substantially.
If applications require extreme intensity stability, the lamp should be warmed up for an additional 30-45
minutes. Once warmed up for this amount of time, the lamp will reach specified drift values.
