Besides Viridian, is there anyone (halfway decent) who makes a light for a handgun rail powered by a single CR123?

Streamlight and Surefire make “double barreled” units, Streamlight has some single CR2 lights, and Viridian has some CR2 and some CR123 lights. I standardize all my lights onto CR123 cells, but I’d prefer a single cell unit for weight and space savings.

Thanks!
