When I get a little bored, I’ll take a cheapo “crappy” flashlight that I bought years ago and mod it into something pretty darn good.
Here’s one that I made in the past. Top is the AA, 1 mode, low CRI, and bluish tinted LED. Bottom is the modified 14500, 12 mode, high CRI, rosy tinted dedomed 519A LED.
What’s cool to me is that you cannot buy this version of the flashlight anywhere. And it didn’t cost that much since I reused parts from other flashlights that I modified.
