Lumens measure the total amount of visible light emitted by a source. A headlamp with a higher lumen rating will produce a brighter light. For instance, a headlamp with 350 lumens can illuminate a wide area, making it ideal for activities like camping, hiking, or working in low-light conditions. When choosing a headlamp, consider how much brightness you need for your specific activities.

The strobe mode on a headlamp produces a flashing light, which can be used for signaling or attracting attention in emergency situations. This feature is particularly useful in outdoor activities where visibility may be low, as it helps others see you from a distance. If you’re hiking or camping in remote areas, having a strobe mode can enhance your safety by making you more visible to others.

Yes, most headlamps with Li-ion batteries are designed to operate in a range of temperatures. However, extreme cold can affect battery performance and runtime. It’s advisable to keep the headlamp and battery warm when not in use, especially in very cold conditions, to ensure optimal performance. Always check the manufacturer's specifications for temperature limits to ensure safe usage.
