thats an ledil angelina 13838, same as the ones for clu048,cxb3590, and vero29
if its hard mounted you see is a tight fit but easy mod, you jsut need to releive the reflector where the solder joints are and drill holes for mounting. that same reflector can also be mated to a cxb ideal adapter or vero 29 adapter but it create a "step" like a cylindrical well that the chip sits down in if that makes sense. of the latter 2 options the vero is better but its A LOT of dremeling. the holder gets dremeled out to the diameter of the LES and then the whole holder gets planed on the bottom. advantage being removable reflector. i dont think im making any more of those until i see if i can do it with the cnc mill
