If you want to build one the same way as i do - here is a list. Of course you can use different ways and components, i am just sharing the ones i have experience with.
You are going to need:
- 1w or 3w power LED
- 18650 power elements or similar (for example flat 4,2v battery packs)
- LM2596 step-down module or similar
- TP4056 safety module with USB charging function
- battery case if needed
- heat conductive glue
- big enough radiator for a LED (ones i use are about an 1" wide and deep)
- optionally some focusing lens
- optionally some wire connector plug and socket (i use 2,1/5,5 ones, makes it comfortable to disconnect the front part of assembly for maintenance)
- some switch (water resistant or with a rubber external "sock")
- some wires
- hot glue
- rubber sheet
I will probably film a video of myself making it, or maybe take a series of photos, we will see.
