Whether you're out for an early-morning jog or hitting the trail after work, the best headlamps for running help you safely exercise in the evenings and other low-light situations. That said, not all head-mounted flashlights are made for movement. Some are better-suited for fix-it projects and tactical uses, so you'll need to take a close look at product specs before buying a headlamp to wear on the go.
The first factor you'll want to consider is the brightness of your headlamp. Brightness is often measured in lumens, which describe the amount of visible light emitted from a source such as a lamp or flashlight. Opt for a light with at least 200 lumensto ensure a bright, far-reaching beam that will keep you visible and illuminate obstructions in your path long before you reach them. While most headlights advertise their brightest setting, some have dimming functions that allow you to customize the brightness to your needs.
Since you'll be on the move, a lightweight headlamp is ideal. Aim for a weight somewhere between 2 and 4 ounces, as this will minimize pressure on your head and prevent bounce while you run.
Finally, consider the overall design and power source. Headlamps intended for use while running typically feature a single, adjustable band made from a stretchy material. This ensures a secure fit without causing discomfort or chafing. In terms of the power source, most will utilize batteries, either replaceable or rechargeable. Rechargeable lights are usually more expensive up front, but they'll save you money in the long run. No matter your preference, one of the four best running headlamps is sure to meet your needs:
