Troubleshooting Common Problems with HID Bulbs

by DoItYourself Staff

HID (High Intensity Discharge) bulbs are gaining popularity due to their lower power consumption compared to ordinary tungsten and tungsten-halogen bulbs. These tips should help if you are encountering any problems with your HID lighting.

First, determine that you are using the proper lamp and ballast for the fixture that is installed. An incompatible ballast and lamp can result in anything from abnormal light operation to complete lighting failure. Once this has been established, follow this guide to assist in troubleshooting any problems.

If HID Lamp Will not Light

Blown fuse. Check fuse on fixture and/or fuse box to determine if it is blown. Test, and if necessary, replace defective fuse or reset breaker.
Defective lamp. Inspect lamp for any defects or broken components, or install a working light. Replace defective lamp.
Photocell failure. Turn lamp off and place black electrical tape over photocell sensor. Turn on lamp and if light does not turn on, bypass photocell sensor to determine if it is the problem. Replace if defective.
Defective socket. Remove lamp and inspect socket contacts for corrosion or damage. Replace if defective.
Damaged wiring. Inspect wiring and test to determine that all wiring leading to the lamp is in good condition.
