Cooling

Cooling

Xenon lamps must be adequately cooled during operation. This is best achieved by forcing air through the lamp’s end fittings and along the lamp envelope at a rate of 15-25 feet per second. The air stream should be as cylindrical as possible along the lamp axis so as not to put additional stress on the quartz glass. Once the lamp is turned off, continue the cooling process for several additional minutes. During operation, lamp seal temperatures must be kept below 225 degrees C.

Excessive cooling can occur, which leads to arc instability. If the lamp voltage decreases by more than 1 volt when compared to the lamp voltage with no cooling, this indicates that too much cooling is being applied to the lamp.
