What Are The Precautions For Choosing A Headlamp?

1. Light brightness
The higher the brightness, the better, and the larger the irradiation range, the better. However, for the irradiation distance, more than 100 meters is enough. If it is too far, the eyes cannot see clearly (except for special purposes).
2. Headlamp weight
The weight of a single battery is not very obvious, but if you wear more than 2 lithium batteries for a long time, your head will feel heavy and uncomfortable. Try to choose a single battery or an additional battery pack.
3. The duration of the headlamp
Buyers who often buy headlamps know very well that they hope the duration is as long as possible, so that they don't need to charge frequently and don't run out of power at critical moments; but the duration of the headlamp is limited, but it is enough to last for 8-10 hours, because the longer the duration, the worse the brightness and the capacity of the battery should be increased accordingly, and the sense of pressure will increase accordingly.
4. Charging time
If the capacity of the headlamp battery is increased but the output current of the charger is not increased, the charging time will be doubled, so when choosing a high-capacity battery, a high-current charger should be selected.
5. Waterproof performance of headlights
Ordinary ones are generally rainproof. If you really dive, most of them will break, so you should learn more when purchasing and buy according to your needs.
6. Elastic band of headlights
For users who wear it on their heads every day, no matter how durable the material is, it will loosen, so you can buy more when purchasing.
7. Close-range problem of headlights
Headlights are OK for long distances, but they can't handle close distances. The light spot is very messy and uneven and has black holes. As for this problem, there is no other way to solve it except for adjustable focus headlights and additional PC covers. Think about your requirements when purchasing.
8. Life of headlights
Some headlights break within 2 months or half a year after they are bought home. A good headlight has a warranty of 1 or 2 years.
