Acebeam H18 Right Angle Headlamp with Red Light
The Acebeam H18 is a dual-source right angle headlamp that pairs four white LEDs with a dedicated red light. The white output reaches 4,000 lumens (6500K cool white) or 2,700 lumens (5000K Nichia 519A high-CRI neutral white) through an optical lens for a smooth, non-PWM wide flood, while the 630nm red light preserves your night vision for camping, hunting, and astronomy.
It runs on an included 21700 6400mAh battery rated for 25A discharge and charges through a USB-C port protected by a rugged metal cover — the battery itself also has a USB-C port. Snap the Acebeam H18 out of its quick-detach bracket and it becomes a 180° adjustable right angle flashlight.
