Re: Surefire Lens
Welcome to CPF, shahzh.
The question of whether a LED drop-in will be OK for the G2 is raised quite frequently.
Surefire do not recommend it, and they make a different head for their LED version of the G2.
The answer is probably best summarized as "If it is a high-output drop-in, don't do it." The problem would be heat build-up, as the Nitrolon construction of the G2 will not conduct heat away very well.
I'm going to move this thread to the LED section, adjust the thread title and close it, as the list of potential drop-ins is almost endless. Details of many of them can be found in
this thread.
