I have a later model SF L1 that supposedly has a TIR optic. It looks like a regular reflector in there to me? I remember the older E1L and E2L lights had a weird bubbly lens in the front, was that the TIR? Also what does the TIR do that a regular reflector doesn't (I have read tighter beam, but how?). I will gladly read a thread on this but I searched and couldn't find one. Thanks.
