Danger! Hot lamps!
The lamps heat up strongly during operation. Allow for sufficient cooling down before you replace a lamp.
Danger! Eye injury from exposure to optical radiation!
Do not look into a burning lamp! Its radiation may damage your eyes.
Soiling of lamps!
Do not touch the glass body of a new lamp. Use particular care to protect the beam outlet window (of quartz glass) of the deuterium lamp!
If there was finger contact with a glass body, use a piece of clean non-shedding cloth and pure alcohol to wipe any finger marks off. Contamination will deteriorate the lamp’s performance features.
