Nice lamp…
I’d like to learn more but I don’t see anything more in the link that you provided.

It’s charged by USB and powered by 18650, right?
What is the charging current?
What is the output?
Are cells meant to be replaceable? If yes, thumb screws would be better as they would allow replacing them in the field.
Does it double as a powerbank? :wink:

It charges from 16.4-16.8v 6A. About 50% by ~20 minutes (4x18650 3.4A), I can add charging resistor
5v 4A to USB, to LEDs goes ~37v (it can be double lower voltage)
You can find any M4 6-16mm screws what you like. I have this ones and they are made of stainless steel
See photos, it is lamp and power bank, that was idea of v.1.1
