Steady state operation

Steady state operation

LTI’s xenon lamps are considered low voltage, high current DC light sources. As an example, a 1000-watt lamp operates at 20VDC at 50 amps. The typical manufacturing tolerance on the lamp voltage is ±2 volts. During the life of the lamp, the voltage will rise as the cathode tip erodes slightly, which causes the arc gap to increase. Over the life of a lamp, the voltage can increase by 2 volts from its initial steady state operating voltage.

LTI’s xenon short arc lamps are considered constant current lamps. This means the operating current is set for the lamp, and the voltage is established by the specific parameter of the lamp including arc gap, xenon pressure, operating temperature, etc. The operating current range for each of LTI’s xenon lamps is specified by model, however in general the current should not be run at less than 85% of the nominal or more than 110% of nominal.
