Russ... the bezel and tail cap are interchangeable between my 6P and L2M... the L2M is a "clicky" tail cap ..., which might be easier to switch between modes if a multi mode module is chosen..the L2M is slightly longer than the 6P... the low voltage XP-G module will also work with a single 123 with the single cell configuration of the L2M, which might have use as a weapon's light... I have a second extension tube (adds one 123) on another Solar Force light that allows 3 x 123 as the M3 head's XM-L2 module can handle 9v... with that extension tube on the L2M, 2 x AA Eneloops work, but rattle around a little

single cell configuration compared to a Streamlight Pro Tac 1L



if you want to light up the alleyway, the 3 x 123 with a M3 (XM-L2) head is a flame thrower
