I purchased one of these to use on my stock Solarforce L2 host, which comes standard with an incredibly pointy, scalloped, bezel ring. While you can unscew the bezel ring, you then have nothing that securly holds the lens in place.
This stainless steel bezel ring is a perfect replacement. Works well. Gives my Solarforce bezel a clean, good-looking appearance. Not to mention the strength of having an s.s. bezel ring in case you drop your light on a hard surface.
