A good flashlight is brightness you can use, runtime that matches the job, and a size you will actually carry. Ignore the 50,000-lumen ads.
What actually matters
- Lumens — output. About 200–500 is plenty for around the house. 1,000+ is easier outdoors. Turbo numbers often step down fast.
- Candela / throw — how far the beam is useful. A flood lantern can have high lumens and still not reach down a trail.
- Battery — AA/AAA and D-cells are easy to find. USB-C 18650/21700 is the 2026 default and usually cheaper per hour.
- Size — pocket, glove box, or “this lives in the garage.” Buy the one you will have on you.
- Durability — aluminum, a real switch, IPX rating that matches rain vs. a sink dunk vs. a dive.
- UI — one button you can use in the dark beats a clever touch panel you have to relearn.
