Cheap 18650 light for 20mm PCB/Driver experiments

I’m interested in building my own headlamp for trail running but I need to do some trials with various LED/driver configs first. I was thinking of just using a single 18650 flashlight host that will take 20mm LED pcb/driver drop-ins for quick and easy testing. I don’t want a reflector on the end, it needs to be the installed bare optic exposed.

Just need to grab a few cheapies (the guts will be thrown), are there any obvious recommendations? Will need to be shipped to Australia.

SK98. Takes 20mm drivers, you can unscrew the front bezel and pop out the lens. Probably can slap in a flat piece of glass in the right diameter to protect the nekkid LED from water, dust, etc., too.
