It may be fluorescent, but it runs from a single coin cell, which I can see through the case. I have had it for over a year. It came from an Eastern Mountain Sports store and was almost $20 at the time, but much cheaper now, I think. My Kelvin & Hughes has what looks like an ordinary small flashlight bulb, so I haven't worried about this. An LED mounted in a bulb base would be a good thing.
