Summary Of Precautions For Using Outdoor Headlights

1. Headlights or flashlights are very important equipment, but the batteries must be removed when not in use to avoid corrosion.
2. A few headlights are waterproof or even water-resistant. If you think waterproofing is very important, buy such waterproof bulbs, but it is best to be rainproof, because the weather in the wild is not something you can control.
3. The headlamp holder needs to have a comfortable cushion, and some are like pens hanging next to the ear.
4. The switch of the lamp holder must be durable. Do not turn it on automatically when placed in a backpack to waste electricity or cause some problems. The switch design of the lamp holder is best to be a groove. If you think there will be problems during the journey, it is best to use a patch to stick it tightly, remove the bulb or remove the battery.
5. The bulb is not durable for a long time. It is best to carry a spare bulb. For example, halogen krypton argon and other bulbs will generate heat and be brighter than vacuum tube bulbs. Although the use will be high ampere and shorten the battery life, most bulbs will mark the ampere at the bottom, and the general battery life is 4 amperes/hour, which is equivalent to 8 hours for a 0.5 ampere bulb.
6. If you are hiking at night, it is best to use a headlamp with a bulb as the main light source, because its effective lighting distance is at least 10 meters (2 No. 5 batteries), and it also has 6~7 hours of normal brightness, and most of them are rainproof. Bring two spare batteries and you don't have to worry about it all night (don't forget to bring a spare flashlight to use when changing batteries).
7. A method to test LED: Generally, three batteries are installed. First install two batteries, and short-circuit the third one with a key for even and long-lasting (compared to headlamps without boost circuits), and the lighting time is relatively long (branded [AA] batteries are about 30 hours), which is ideal as a camping lamp (that is, for use in a tent); the disadvantage of headlamps with boost circuits is that this type of headlamp has poor waterproof performance (most of them are not waterproof).
