Flashlights with Brightness Memory

Cheaper torches often reset to their brightest, or dimmest, mode every time you switch them on, forcing you to click through every setting again to get back to the one you actually wanted. Brightness memory fixes that: the torch turns back on at whichever mode you last used.

It's a small feature, but a genuinely convenient one, especially if you tend to run a torch on a specific low setting most of the time.
