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)
- 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.
