Clean fixture.

 

 

 

 

 

 

Wrong Lamp?

Check data on lightswhich appear different in color. Replace

 

with correct color lamp.

 

 

 

Over Voltage from Power

Check voltage at ballast. Check for current or voltage surges.

Improper Ballast?

Lamp operated on ballast designed for higher wattage lamp.

 

Check ballast nameplate against lamp data.

 

 

 

 

Check for outer bulb cracks. If air enters outer bulb, arc tube

 

 

may continue to burn for 100 hours before failure. Check for

 

 

bulb cracks where glass meets the base due to tightening

 

Lamp Damaged?

Lamp too firmly in socket or scoring of glass where socket

inadvertently touches the lamp bulb. Look for broken arc tube

 

or loose metal parts. Replace lamp. (Bulb leads will cause

 

 

 

 

oxidation of metal parts.)

 

 

 

 

 

Ballast nameplate data should agree with lamp line voltage

 

Improper Ballast?

and lamp use. If improper ballast is used, the lamp life will be

 

 

shortened. A mismatch may also cause the ballast to fail.
