I’m interested in getting a “fancy” flashlight as a “toy” to show off
something unreasonable, like an all-copper light with an ~1800–2200K LED.
I would prefer: (but not strictly)
thrower (as good as possible in a small package
Single emitter
TIR optic
18650 or 21700 battery
USB-C charging
Most importantly, I want an over-engineered, fancy, “community” flashlight driver with a preferably open-hardware, high-efficiency DC-DC driver. (Absolutely no direct FET driver)!
So preferably a boost driver.
Maybe something like an Emisar D1K with an NTG50 in 1800K neutral tint and the Lume X1 driver.
(but is the Lume X1 truly open hardware? is there a schematic?)
The goal is less “practical edc tool” and more “flashlight as functional art”
premium materials, beautiful tint, excellent engineering, and enthusiast appeal.
waht options and ideas you have? i’m ok with modding a existing light.
if there is fitting a driver i can actually buy, but at the moment i’m not interested in building an one of led driver for scratch.

I didn’t explicitly say it, but “mule” is not what I want in terms of beam pattern. I want something more of a thrower with high intensity
basically as throwy as possible for its diameter while still being somewhat efficient. It also shouldn’t be much bigger than a C8, preferably even smaller.
That’s why I mentioned a single-emitter TIR. The multi-emitter 3-LED and 4-LED TIR optics are all too floody for my taste.
Also, is the Lume1 truly open source? I can’t find the schematic, and the buck-boost version seems to have a “FET turbo” mode.
i like it! but it’s only only available in ordinary aluminum.
For fully aluminum the price is a bit high. i would be ok with this. but i like copper… or brass
While loneoceans TPS61288 based Lume driver seams to be excellent i still wonder if it is open hardware and if there are schematics available?
You will have to look into custom market to find what you’re looking for.
If I was building it, it would be Convoy M21H shape/size in copper with that driver you just picked and NTG35/FFL351A led in 1800/2200K with 35mm 3° TIR optic
Hm it has the Open Hardware Logo!
BOM and Gerber is online but for some reason no schematics?!
And only for the Fet driver version?
And both don’t have usbc charging while the Fireflite X1S Pharos seams to have usb charging and claims to uses the lume driver.
Maybe it uses multiple completely separated boards?
maybe @loneoceans can explain waht driver is soled/made under what license and if there are schematics.
