Yes, the "L" models use a CR123 battery (or 2).
I second the vote for the 3C model. It's the brightest AND longest running. I keep one in both cars. With 3 LEDs it fine for map reading at night. You can easily change a tire with 6, and if you need a really bright light, the incandescent is (I think) around 50 Lumens (if they claim more, it's not true!)
