A Sofirn C8F as a Hexad Mule

This is a quite old Sofirn C8F. It is from the first batch made. It does have the odd wear or handling mark or two. A while back I stripped it and baked it to a brown toast color.

When led4power was clearing out stock last November/December I bought a number of things. There was a very good price on assorted mcpcb’s with SST-20 emitters; 4000K and 95 CRI. I bought one mcpcb with 6 SST20’s, meant for use with a ledil Anna optic. I made a mule.

Several 1/8” thick laser cut aluminum rounds were used to form a spacer. A center hole was drilled in each and a bolt inserted. The drill press was used to spin the assembly and a bastard file used to shave the diameter down to make the spacer fit inside the head.

Holes were drilled and tapped in the head to allow securing the discs. Additional holes were drilled and tapped to secure the mcpcb in place.

A 17mm FET driver was used with Narsil firmware. (Yes, it is old firmware, but very simple and easy for anyone to use. No bells and whistles, tricks or hidden functions.) It ramps up and down, has instant ML and turbo access, plus battery check and e-lockout. I cut a slot in the switch location to allow insertion and removal of the switch without the need to solder/desolder the leads.

It works

What is a light without some wood? It couldn’t be one of mine without… I added a wood disc I made from my leftovers box.

No beamshots as it hasn’t been dark since I finished it.

High output level, not turbo. Sorta bright. Lots of heat too. Maximum flood. Smile I should measure the amps at tailcap. The shadow is from the chair No other lights on in the room except for the amber glass shade table lamp in left side. It is not very bright

It just wooden be the same.
Very nice mule, good heatsinking for the size of the host, those LED boards are great and Narsil is my favourite UI. And you might have inspired me to swap the driver in my C8F.

Edit – and i haven’t commented on the workmanship because i have no place to judge it, that’s the first time i’ve heard of a bastard file.

I also used a smooth file to finish the surface more… smoothly. Smile

That’s the most fun part of teaching a bunch of Boy Scouts how sharpen an ax, you get to say “mill bastard.”
