surefire z2 combat with old KL3 head.......help

I have an old style z2 with kl3 head and tail clicky.

it is SOOOOOOOO dim compared to anything these days.

are there any mods I can do on this light or does it belong in a museum?

I don’t know about KL3 head but I’ve done this trick to KL4 head.

I opened the bezel and remove the component then insert P60 drop-in from the front.

Thank you, I might end up giving that a try. I will take pics of my attempt.

Yes, you are going to want to remove the old optic abd LED and replace with with a new Led and 27mm reflector. Is it the old finned KL3 or a newer one? I’ve modded 3-4 of the old finned ones, years ago. It is one of my favorite heads.

newer one I believe. no fins. https://static.bhphoto.com/images/images500x500/Surefire_KL3_HA_WH_KL3_LED_Conversion_Head_1233061782000_471432.jpg!
