Important: Disconnect power before servicing or attempting to troubleshoot any fluorescent lighting fixture!
Often a fixture becomes inoperative due to causes not attributable to the ballast. It is therefore important to examine all fixture components before removing the ballast for replacement. We recommend the following general procedures for both magnetic and electronic ballast.
- Replace or check all lamps to ensure satisfactory operation.
- As lamps are removed, examine all sockets to ensure they are not damaged or broken and are making proper and positive contact with the lamps.
- Examine all electrical connections within the fixture, including at the lamp sockets, to ensure conformance with the wiring diagram on the ballast.
Cold temperatures usually cause lamplight swirling or spiraling, when the light appears to swirl or spiral inside the tube. In this case, shield the lamps from the cold draft, from air-conditioning or other sources by using a plastic jacket available from distributors. Make sure the plastic jacket (tube guard) is rated for the lamp/ballast combination. It is not advisable to use tube guards with instant start T8 ballasts as high heat from the lamp ends at end of lamp life may cause the tube guards to melt if the lamps are not changed immediately.
This problem may also be caused by low input voltage or lamp and ballast incompatibility. Check the input voltage, which should be the ballast rated voltage +/-7.5% or change the lamp to a known good lamp. If the condition still exists, change the ballast.
