How to buy your first Rechargeable Headlamp when you are new to the outdoors
In outdoor activities, the light source is indispensable, especially in outdoor sports such as mountaineering, hiking, and cross-country. The light source is the glasses in the dark, which is very important. In order to liberate hands during outdoor exercise in the dark, without affecting the flexibility of exercise, there is also a "headlight". Today we will mainly talk about how to choose your first Rechargeable Headlamp.
Rechargeable Headlamp, as the name implies, is a light source that can be worn on the head or hat to free your hands and illuminate. Headlights are currently often used in trail running competitions. Whether short distances of 30-50 kilometers or long distance races of about 50 to 100, they will be classified as mandatory equipment to carry. For ultra-long races greater than 100 kilometers, you need to bring at least two headlights and spare batteries. Almost every contestant has had the experience of walking at night, and the importance of Rechargeable Headlamp is self-evident.
In the call-up posts of outdoor activities, Rechargeable Headlamp is often listed as a must-have equipment. The road conditions in the mountainous areas are complex, and the plan is often not completed within the set time. Especially in winter, the days are short and the nights are long. It is also crucial to carry a headlight with you. It is also essential in camping activities. You can use it for packing, cooking, and going to the bathroom in the middle of the night. In some extreme sports, the role of headlights is more obvious, such as high altitude, long-distance climbing and caverns.
So how should you choose your first headlight? Let's start with the brightness.
Rechargeable Headlamp must first be "bright", and different activities have different requirements for brightness. Sometimes you can't blindly think that the brighter the better, because artificial light is more or less harmful to the eyes. It is enough to reach the right brightness. The unit for measuring brightness is "lumens." The higher the lumens, the brighter the brightness.
The battery life of the Rechargeable Headlamp is mainly related to the power capacity of the headlamp. The usual power supplies are divided into two types: replaceable and non-replaceable, and there are also dual power supplies. The non-replaceable power supply is generally the lithium battery Rechargeable Headlamp, because the battery shape and structure are compact, so the volume is relatively small and the weight is light.
In addition, Rechargeable Headlamp should use constant current circuit as much as possible, so that the brightness can be kept unchanged within a certain period of time. The cost of the linear constant current circuit is relatively low, and the brightness of the headlight will be unstable, and the brightness will gradually decrease with the extension of time.
The range of Rechargeable Headlamp is commonly known as how far it can be illuminated, that is, the intensity of light, and its unit is cd. 200 candelas have a range of approximately 28 meters, 1000 candelas can have a range of 63 meters, and 4000 candelas can have a range of 126 meters. 200 to 1,000 candela is sufficient for ordinary outdoor activities, while long-distance hiking and cross-country races require 1,000 to 3,000 candela. For cycling, products of 4,000 candela can be considered. For activities such as high-altitude mountaineering and caving, 3,000 to 10,000 candela products can be considered.
