D)
When installing a new lamp, do not touch the glass envelope of the lamp with
bare fingers. Oil and grease residue burn into the quartz housing and lower the life
expectancy. Remove the foam or plastic safety cover of the lamp only after placing
it in the socket or touch lamp only with a lint-free cloth. If the glass housing is dirty,
it may be cleaned off with a soft cloth and pure alcohol.
Make sure that the lamp is seated all the way down in the socket and the knurled
fixing screw on the rear side of socket is closed.
Follow precautions as described in 3F.
After the door has been closed, the black latches must engage audibly.
Average lifetime of the 800 W metal halogen lamp is about 700 hours. This
refers to a cycle of three hours on and one hour off.
Frequent on/off switching, dimming or use in boost “ “ position shortens
lamp life.
The probability of an explosion of the lamp is very low. However, if the
average lifetime is exceeded by more than 25%, the risk of a lamp explosion
noticeably increases.
