The words ‘focused light’ indicate a spotlight beam and the words ‘wide beam’ or ‘floodlight’ indicate a more diffuse light. Check out the type of light a headlamp offers under our ‘Product Details’ tab for the lamp. A floodlight type beam will provide a more diffuse light to help you see peripherally. A focused or spotlight beam will produce a crisper, more concentrated light that allows you to see farther ahead. In addition to light output, light pattern and distance are worth considering. Many headlamps will list the burn time for the various light settings, but if only one burn time is listed, you can assume it’s for the lowest light setting. Although your headlamp won’t be producing an optimal amount of light when the batteries are low, it’ll likely be enough light for you to see your way out of an emergency situation. If you make sure to slot in a fresh set of batteries before heading out, you should be fine with either light type for at least 8-10 hours.Īnother measurement of light duration is known as ‘burn time.’ This will tell you how many hours a headlamp can produce usable light at a minimum of two meters. These headlamps with ‘regulated light output’ offer the advantage of consistent lighting, but beware: the light will cut out abruptly when your batteries run out of juice. But some headlamps are designed to provide steady light that only dims slightly over the duration of the battery life. The light output for most headlamps will gradually decrease as battery life decreases. A headlamp that maxes out at 40 or 50 lumens can offer plenty of light for a night run on city streets, while tackling trails in the deep woods could require a lamp that can produce 100+ lumens for adequate visibility. Lumens measure the brightness of a light at its source, not the amount of energy it uses. While you may be more familiar with watts (a measurement of energy usage that appears on your bulbs at home), headlamp light is measured in lumens. And if your runs have you spending many hours in the dark, you want a light that will stay bright throughout. Of course, a headlamp must have enough light for your activity and environment. Read on to learn key features, and check the end of the post for some top picks. If you’re planning to keep your runs going strong even though you have fewer daylight hours to work with, you’ll need some illumination, and a headlamp can be a great option.
