Discharge lamps operate under high pressure. As the lamp ages, the glass envelope becomes more fragile. To reduce
the risk of the lamp exploding, which may cause damage to the fixture, do not exceed the rated average life by more
than 25 percent. The procedure for installing the lamp is described on page 5. After installing the lamp, reset the lamp
usage counters as described under "Readouts" on page 11.
