My Solarforce L2 was shipped with a crenellated (tactical, strike) bezel ring, which I didn't like right out the packaging. It's aggressive on hands, pockets and furniture, it makes the flashlight 7-8 mm longer than absolutely necessary - in other words it's awkward and clumsy.



So out came the Dremel tool with coarse sanding drum, and later a sheet of 100 grit sandpaper. Crenellations and ring were sanded away right down to the ledge! The remaining threaded ring was then inserted backwards (sanded face down). This is how my L2 looks now:





There is a chance that this mod allowed for a few lumens higher output, beam spill seems a bit wider and there is an aesthetic improvement (IMHO). Ring is still removable and replaceable without a tool...
