Not luxury, but I keep a small AAA flashlight with me nearly all the time.
Easier to handle and faster to use than a phone light. Also doesn't use phone battery. I clip it on my hat if I need both hands like taking out the trash.
I have an Olight i3T but I would try out the i3T 2. More lumens and better battery efficency.
Few dollars over OP's request, but an Olight Oclip is straight awesome for a multipurpose light. Simple UI, super lightweight, long lasting, quick charging (USB-C), magnetic or clip-on, extra LED for red light.
I clip mine to the cross piece on my hiking pack to illuminate the trail. I've also used the red blinky light so my wife can be certain where I am, nobody think I'm a deer and shoots at me, and so 4-wheelers can spot me.
