I’ve got a Z1 with the SFT40 and the plain 8 Amp Convoy driver- so I was very interested. Did you compare the output drop off over a couple of minutes? I know my Z1 doesn’t seem to drop much on the highest setting.
It was raining so I didn’t stay outside too long.
But the Z1 got noticeably warmer faster than the TD01C.
I used fully charged Molicel P42A in both lights.
I know it’s not exactly in the OP but I’m ultimately waiting on the Sofirn SF26 to have a regulated driver because I really prefer the USB cover design for the Sofirn. The beam shots are really nice and the comparison further convinces me that my Cometa/SFT40 is sufficient for now. Thank you!
One thing I should mention.
It’s hard to tell in the beam shots but the TD01C beam seems to have much better color rendering vs the Z1.
I don’t know for sure what’s causing it but I suspect it’s the difference between the TIR and Aspheric Lens.
In the beam shots the Z1 looks cooler but there’s more to it than that.
I haven’t heard anything about the Sofirn model. No one really mentions it (as much as I have read) but there’s been, almost, a requirement of forum members of that on the Wurkkos model. I’m just wishing.
Instead of wishing you should message Barry or sofirn directly.
The TD01C buck driver came about as a result of a lot of people collectively pestering and requesting of it from Wurkkos’s rep Terry.
Having said that - I don’t have much hope in Sofirn any longer. They are far less responsive to community feedback than they used to be. There’s more luck in Wurkkos. Perhaps you can ask @Wurkkos_Terry if they could adopt the TS26 usb-port in some of the Wurkkos models.
This makes perfect sense as an aspheric collects only emission to the front of an LED, not emission to the side. The beam would thus be much more blue-dominated and miss out on reds and greens, resulting in higher CCT and lower CRI despite more magenta tint.
Unrelated, but this is essentially the reason why I personally dislike the idea of high CRI mules.
