Well I can tell you that if you do plan on making your own flashlight, start small. I would make it P60 compatible, and have it powered by a single 18650 li-ion cell.
A P60 is an extremely popular "drop-in" format. I suggest using a R5 LED in the P60 format
Thanks for the info and the links. A few questions:
-Why would I need to be skilled at lathing, because I'm not?
-What else do I need besides a host + drop-in + battery + possibly o-rings?
Let me ask a few more specific questions:
1) If I have a Surefire 6P and put a 3-mode drop-in in it, how does switching modes work.
2) Are the tailcaps from Solarforce lights, like the L2P, useable on a Surefire 6P?
3) Will someone share some general knowledge surrounding mode switching on a light like the 6P, when using a custom drop-in?
Ps Any other helpful information on this general topic would be welcome.
If you have a Surefire 6P you would press the momentary switch to change modes and twist the tail cap to keep it on a particular mode or just twist and untwist until you get the proper mode.
I would rather have a clone with a clicky switch with a multi-mode drop-in.
P60 drop-ins are available for XR-E R2, XP-G R5, as well as for P7, MC-E, SST-50 and SST-90 I guess.
I wouldn't want any more than the XP-G R5 in a P60 drop-in.
I second this. If you want more power get a bigger light! I've never heard of a sst-90 p60. If it did exist no flashlight that is P60 compatible would be able to hold enough batteries to keep up with the massive amperage the SST-90 draws.
Plus there are heatsinking issues involved with running hot LEDs in a P60 drop-in.
A Surefire 6P would handle it a bit better because it has the "cup" that holds the drop-in, whereas the non-Surefire hosts have a wider opening with a fair amount of air between the drop-in and the head.
