Add in that slim little percentage of Tellurium to the Copper and once it again it machines like brass. Well worth it if you ask me…
On another note, but some machining still involved… I managed to trade my son a newer light for his Jacob A60 then coaxed 227.5Kcd from the old pencil beam thrower.
Good job on the A60 Dale. I still take its stock 55 kcd (with XR-E led) as my reference point for throwers that I make, to feel good about how much flashlights have improved
What led does it have now?
I machined the emitter shelf to accept a 20mm Noctigon with a White Flat. Using an FET+1 A6 style (that I built) and limiting power through cell choice, currently running a Panasonic PF that gives 6.01A at 4.19V freshly charged. Yeah yeah, I know, I have an LED4Power LD-A4 on the way that I will set to a little lower current to optimize the emitter so improper cell choice won’t kill it should I forget (and I will!).
When the LD-A4 arrives I plan to make a copper “retaining ring” that will hold the smaller 17mm driver, just replace the very thick aluminum retaining ring with one made from copper that has a shelf for the driver then solder the driver in after installing. (or if I take a notion I’ll make a retaining ring to fit within the retaining ring to hold the driver. Depends on the variables…
I modified the CRX Rotary with a 3K carbon fibre jacket and swapped the XP-L HD 3D emitter for an XP-L HI 3A 5000K as I found the XP-L HD 3D tint to be a little too green on the lower modes so now it's a much nicer creamy white to my eyes.

Modding the UF-C1 (P60) and the Revtronic PT20, to both I added the light cap. The PT20 has already been modified by replacing the reflector with a 120° TIR; I use it only in the house and so is very handy
My friend sent me a Lumintop Tool AA/14500 Ver. 2.0 that arrived yesterday. It had an XP-L HD in it but that didn’t last long, I pulled the pill out, filed off the raised outer edges and filed down a 16mm Noctigon to fit squarely on top of the aluminum pill, then placed a White Flat on the Noctigon. Left the driver alone so it can run AA or 14500 either one. The White Flat makes 538 lumens on a Red Efest 14500 not fully charged and the hot spot is more concentrated with less spill. Works for me!
Convoy S11 with XHP50.2 80 CRI 4000K and 6V 4.8A boost driver. Modes: 0.1A, 0.4A, 2.3A, 5A. On max mode it takes almost 10A from the battery, however that is too much for the switch and the driver warns about low voltage.
Interesting. That cell should be capable without running into issue. The only cell I know for sure that is better, same class, is the Golisi in gold. Changing class to a 21700 the 30T or 40T may still outperform the Golisi but it’s marginal even there. The Golisi is markedly better than the LiitoKala black…. still, perhaps a good cleaning of all contacts with De-Oxit Gold would help?
Spring bypasses will help. If it has an Omten switch, even a mini, you don’t have to worry about the switch, they can run up to around 30A before having any real issues.
