This product uses XPG and COB LEDs, which are energy-efficient, highly effective, and long-lasting. The dual-switch control system supports multiple lighting modes: Mode 1 allows switching between high, medium, low brightness, and strobe modes via continuous clicks; Mode 2 offers high white light, medium white light, red light, and red-green flashing modes. The pen-shaped design makes it easy to carry, and the strong magnetic clip securely attaches to metal surfaces.
