Hum, generally the pill is where the MCPCB with the emitter(s) sit and on the inferior part you will fit the driver!
Take a look at this thread by kiriba-ru! Low-cost copper pills, spacers, optics, drop-ins (Updated 23/10/2022))
He machines pills and spacers so maybe you can take a look at those!
They are normally made of brass or copper, sometimes alluminium! Ti pills…I don’t know! Maybe DB Custom made some as he also loves Titanium!
With a triple board with XPG2 or XPL emitters, with a Carclo 10511 TIR optic, with a H17F driver, with a Samsug 30Q or Vapcel 1100 battery, you will surely put lumens out of your flashlight!
BTW, Steel Flame is a “brand” of flashlights or pocket clips? Couldn’t find the flashlights :zipper_mouth_face:
