I’ve been using the Fenix HM50R for backpacking. I like that you can adjust it up or down unlike some others where they have a top and bottom to the lamp. I can take it off the band and use it as a flashlight and it can also be clipped on my gear. Rechargeable, multiple brightness settings, and red light.
Wicked light ScanPro. Gives you an adjustable beam and brightness, red, green or white light option and runs on 2, 18650 batteries. Designed for hunting but very versatile.
