Frequently Asked Questions

Q: What does an ignitor do?
A: An ignitor provides the starting pulse that lights a discharge lamp in a fixture. Without it working, the lamp may not strike.

Q: Does it work with both HPS and MH lamps?
A: It is listed as a replacement ignitor for High Pressure Sodium and Metal Halide setups. Check your ballast and fixture specifications before installing.

Q: How many come in an order?
A: Each order is for one ignitor. Add more to your cart if you want spares.

Q: How big is it?
A: It measures 1.5 in long, 2 in wide and 3 in high. That small size makes it easy to keep on hand.

Q: Is this the same as a ballast?
A: No. A ballast regulates power to the lamp, while the ignitor provides the starting pulse. Replacing the ignitor does not replace the ballast.
