Suggestion: make the tripod thread on the tail the larger 3/8” size and supply a chromed brass adaptor to reduce it to the 1/4” size.
This is what e.g. Astrolux did on the MF01, and is a great solution to any concern of wearing/stripping plain Al alloy threads. The 3/8 threading is much stronger, and most of the time the brass 1/4” adapter will be used, and easily replaced in the unlikely scenario of it wearing.
No decent camera has threading straight into bare metal (or plastic), they all use a bushing of suitable metal, for good reason.
The threading does need to be deep enough to take a standard length tripod screw. For example, the thread on the Q8 head is far too shallow. I can’t attach it to any of my tripods without it bottoming out, or using a washer to make up the difference, meanwhile hanging on by just a few threads. On the Q8 the flat area surrounding the tripod thread is also far too small, no way to use a standard tripod because the sticky-out bits (technical term) of the curved head get in the way.
Don’t forget provisioning some way to hang this up, even a bail handle that could be clipped onto the head with just two small holes. Also necessary for walking about with it. Every decent lantern I have has such a handle.
My use for lanterns is base-camp, night beach fishing and boat fishing. Which needs a handle to carry it while walking, complete water-proofness, corrosion resistance (no not typical Chinese “HA3”, edit: and the threads protected inside the preferably double o-rings, not outside, see good dive-torches for how to do this), and a stable base suitable for any surface. And immense ruggedness.
Second duty would be domestic power-cuts.
Standby drain should be zero. This is where mechanical switches deliver. With E-switch there is always a slight concern.
Integral charging, powerbank facility etc. is low on my priority list. Efficiency i.e. run-time CRI and colour temperature (warm) is high.
