Time zones are an endless source of frustration, this one doesn’t sound too bad though:

Going forward, all timestamps in the API are switching from timestamps without time zone (2023-09-27T12:29:59.113132) to ISO8601 timestamps (e.g. 2023-10-29T15:10:51.557399+01:00 or Z suffix). In order to be compatible with both 0.18 and 0.19, parse the timestamp as ISO8601 and add a Z suffix if it fails (for older versions).

The reflector of the flashlight is built so light coming from a very small source (like the filament of an incandescent bulb) is directed forward in a focused beam.

I agree, but I also think that using a modern LED with a single source of forward-facing light is fine. However the emitter would need to be properly positioned in the light.

Here’s a very similar host (from one of the best low-cost flashlight makers) showing a properly aligned LED and reflector:

I found a few references to this exact model on candlepowerforums.com which I believe has more folks who own(ed) incandescent lights. Not that has been such a long time, but LED technology advanced very quickly. Not sure if that will help your search.

There’s also a few people over on !flashlight@lemmy.world !

@Spicy3d@lemmy.world check out this diffuser!

Cool project and post! There’s also !flashlight@lemmy.world if you’d like to cross post.

gets hot enough to burn you if you leave it on for too long

That Fenix looks like a reliable light and is designed with temperature regulation but the limit might be pretty high and of course it is being used in an enclosure.
