Frequently Asked Questions
Do I really need more than 300 lumens for night hiking?
You rarely need maximum brightness unless you are moving fast on technical terrain. Most of your time will be spent at 20 to 50 lumens inside camp. Keep the extra power for short bursts when you need to spot a distant landmark.
Is it worth paying more for a waterproof rating?
If you hike in unpredictable climates, an IPX4 rating is a necessary insurance policy. It protects your electronics from rain and sweat without adding significant bulk. Paying a bit more for quality seals prevents a dead light in the middle of a storm.
How long should a single charge last?
Most ultralight models provide 10 to 20 hours of light on a medium setting. If you are out for a week, you should carry a small power bank to top off your battery. Always check the manufacturer's runtime chart before heading out.
Are rechargeable batteries better than alkaline?
Rechargeable units save you money and reduce the weight of carrying spare packs. They provide a consistent light output throughout the battery life. Alkaline batteries often dim slowly, leaving you in the dark as they drain.
Will the strap lose its elasticity over time?
Elastic bands inevitably stretch with heavy use and exposure to sweat. You can extend the life of your strap by hand washing it in cold water after a long trip. If the band loses its tension, most companies sell replacements for a low price.
