You have options with the Coast XP9R Rechargeable LED Flashlight: brightness levels from 67 lumens all the way up to 1000, a focused spot beam or a broad flood, and USB-C recharging or disposable batteries. The three brightness levels cover a wide range of needs, from household use to professional public safety or industrial activity. Changing beam size is easily accomplished with one hand, just slide the light head forward for the Bulls-Eye spot beam or back for the Ultra View flood beam. Twist the head to the left to lock the beam into place. The Coast Zithion-X rechargeable Li-ion battery has its own USB-C charging port. If recharging isn't an option, you can power the light with two CR123A batteries.
