View Full Version : how long does an ignitor usually last

I have an Advance ignitor for 250w MH bulbs and one appears to have went on me. I have two others and am wondering if I should prepare to replace them as well. They are about 5 years old.

They are rated for 10,000 to 50,000 continuous/working operating hours.

The ignitor is only used (in operation) to fire/ignite the lamp and the ignitor generally only operates for less than a minute.

The ignitor on that ballast will also continue operating if the lamp fails to light or no lamp is operating. If the lamp is not replaced for a while the ignitor will fail quickly. This is a common problem with commercial lighting. Manufacturers offer timed ignitors. If the lamp fails to light within 15 to 20 minutes the ignitor turns off.

Generally the ignitor lasts a long time. I’ve seen in some applications the ignitors have lasted 15+ years with every day use. It could be your ignitor failed for unknown reasons. The life rating is also done by temperature. Cooler the ignitor is the longer it will last.
