tldr; Budget thrower with SFT40 or LHP73B. Incredible value for distance. Heats up fast but pocketable.

“The closest thing is the acebeam e75, which I recommend instead because it is a really nice light! I love mine. It comes with the 519a led which is high cri, neutral white, and has a nice looking beam. It's also got usb c charging. You can also take out the magnet if you need to”
