Modded a Sipik HK21 for a fellow CPFer.
Dis-assembly of light in post #20 here.
Stock light:
Parts supplied:
Removed head with strap wrenches.
Glue was pretty easy to break through.
Threads were cleaned up to removal residual adhesive.
Head unscrewed.
Retaining ring unscrewed.
Pill slides out with some tapping.
Noted there was no thermal paste under emitter.
"Pressed fit" stock 5-mode driver easily pops out with screwdriver.
Driver wired.
Negative contact was a challenge since the double-PCB driver protruded a little from the pill. I soldered a negative wire and bent it for contact. I tried soldering it to the aluminum pill, but of course the soldered would not stick L. I also added a solder blob to the driver + contact.
Emitter mounted with thermal paste and wired.
Retaining ring screwed back on.
Custom insulator ring. Serves to prevent short circuit against aluminum reflector and gives it optimal position for perfect focus.
The XPG requires the head to be slightly unscrewed for focusing, so a small gap was left between the head and switch assembly.
Solder blob added to battery + contact point on switch PCB. This allows use of flat top cells.
Current draw at low, medium and high settings.
1 foot beam shot against white wall at low, medium, and high settings. My camera has no manual exposure settings, so it tries to adjust automatically.
Completed light with some O-rings for a unique look.
Hope the member likes it!
Thanks for looking.
Comments welcome.
