Undercabinet Fluorescent Light Ballast

Single-tube fixture with 18" tube quit working. Replaced bulb, no joy. Pulled fixture and checked voltage. Voltage OK.

Could ballast be bad? The fixture is less than 2 years old, and I thought ballasts were supposed to last 40k hours. A new ballast costs $20 and up. So does a new fixture. I'm not a fan of fluorescent, so I'm considering putting in a 3-lamp halogen fixture in its place. Will the wavelength clash with the remaining undercabinet fluorescents?

How do you troubleshoot/check out a ballast? I thought about replacing with a known working ballast from a sister fixture. Is there an easier check without disassembling a good fixture?

In general, if you put in a new lamp and it doesn't work, and the ballast is getting power and neutral, the ballast is no good. There really isn't a good way to test one.

A replacement fixture is usually about the same price as a ballast when you are dealing with undercounter lights.
