hmmm LD50 looks to complete with Olight's Baton series, while the LD41 looks like a cross between the TK35, and the larger head of the PD series. Don't like the fat boot on it though. Aesthetically, the PA40 of Jetbeam would be a better choice. It's like a LD40 clone with a carbon fibre reinforced body and probably the same XML led like the LD41. (best guess due to similar output levels)
