Difference between revisions of "P60"

Surefire created an assembly called P60 that goes inside some of its flashlights. It is a 6-volt incandescent bulb and reflector assembly (for instance, the Surefire 6P, M2, and G2 flashlights all use the P60 assembly). They also make a LED version called a P60L and 9-volt versions called P90 and P90L that are the same size. This became an industry standard and now many companies offer '''P60 drop-ins''' (the bulb and reflector assembly regardless of bulb type or voltage) and '''P60 hosts''' (flashlight bodies that accept the drop-ins). Some companies avoid the Surefire naming system by calling P60 a D26 (the bezel diameter is 26.5 mm) or won't even mention P60 at all. No soldering is required: you just unscrew the head of the light, drop the assembly into the host, put the head back one, and you are ready to go.  

Make sure you match up voltage requirements. For instance if you get a 3.7-4.2V drop-in, don't operate it using two CR123A batteries which would be 6V. LED drop-ins include the reflector, LED, and [[driver]] and are available as single mode or multi-mode, though the drivers could be swapped out separately to change that (requires soldering). The [http://www.candlepowerforums.com/vb/forumdisplay.php?f=45 LED forum] of CPF has a sticky listing P60 drop-ins with a link to a list of P60 hosts. The advantage of the P60 system is that once you find a host you like, you can upgrade to a newer LED by just buying a new drop-in which will come with a reflector and driver designed for that particular LED.
