2.12 LAMP HOUSING

The lamp housing consists of the light source valve and connector for the power supply
unit.
* The life expectancy of the light source valve is 4000 hours. When operating time
exceeds 4000 hours, the lamp indicator on the control panel blinks automatically. If
you encounter this condition, replace the light source valve as soon as possible.
* The safety switch on the lamp outer housing, beside the lamp housing, detects
overheating. If the temperature exceeds the safety zone because of abnormal lamp
conditions, this switch shuts down the power.
