Osram Xenon Xstage Lamp

Troubleshooting Osram Xenon Lamps >450W lamps to include XBO® and Xstage types

When paying top dollar for Osram Xenon Bulbs like the Osram XBO and Osram Xstage lamps, the expectation is a high performance lamp.  The following are some common problems with osram xenon bulbs to why xenon lamps are not performing as expected

Symptom Fault Remedy
Connector base
discolored
Connector base overheated
above 230°C due to:
- Faulty electrical connection
- Improper lamp cooling
- Improper lamp current
- Optical system out of
alignment
Check electrical
connections:
- Tighten or replace
- Check operating current
- Check cooling system
(forced or convection)
- Check optical adjustment
Blackening or clouding
of quartz bulb
Operational air infiltration
due to:
- Crack in graded seal
typically caused by
overheated connector
base (maximum
temperature of 230°C
exceeded).
Ensure proper operational
current. Check
electrical connections:
- Tighten or replace
- Check cooling system
- Check optical adjustment
- Check operation current
Severe cathode
electrode damage,
grey/brown deposits
on quartz envelope
Reversed polarity due to:
- Electrical connection
incorrectly applied to
lamp
- Incorrect wiring
Check polarity, correct
connections if necessary.
- Vertical lamp operation
only with anode
electrode (+ connection)
up
Abnormal anode
electrode deterioration,
blackening of lamp
Arc instability due to:
- Lamp operated outside
current control range
- Lamp operated with
poor quality operational
current
- Improper magnetic
stabilization
- Improper forced cooling
Check correct current
setting
- Check magnetic
stabilization
- Ensure proper quality
current
- Ensure forced cooling
as required by OSRAM
Deposits on anode
face
Rectifier/power supply
defect:
- Inrush current limit
exceeded
- High current ripple
Check
- Rectifier/power supply
- Inrush current
- Current ripple
