Folomov builds rechargeable high-output LED flashlights, and the B5M shows the formula at its best: 2,500 lumens from a CREE XHP50.2 LED and a 26650 battery in a light that still fits the palm of your hand. A single side switch runs four brightness levels plus SOS, beacon, and strobe, a switch-lock guard keeps it from firing in a pocket, and the beam reaches 327 meters when you need distance. The built-in Micro USB port charges the included battery, and it works in reverse: the B5M doubles as a power bank for a phone in the field. The battery, charging cable, and pouch all come in the box. The rest of our flashlights, including the full Olight lineup, cover every rechargeable EDC, tactical, and weapon-mounted configuration Folomov doesn't.
