In life, whether it is a sudden power outage or an emergency caused by natural disasters, emergency lights play a vital role. They can not only guide us in the dark, but also help us quickly find escape routes or tools and items needed to deal with emergencies.

However, not all emergency lights are up to this task. In order to ensure the purchase of quality and practical products, we need to pay attention to several core indicators. First of all, the choice of material is very important-high-quality shell material can effectively protect the internal components from impact or corrosion; secondly, the type of light source is also one of the important factors to determine the lighting effect, LED because of its high efficiency, energy saving and long service life become the mainstream option.

In addition to quality, the design form also largely determines whether the emergency light can meet our specific needs. For example, portable emergency lights are small and light in size and easy to carry for travel, camping and other activities. The wall-mounted type is more suitable for fixed installation on the wall of the household or in the office as part of the standby power system to start the working mode at any time. Therefore, it is very important to clarify your main application scenarios before purchasing.

Battery life is another important consideration. A good emergency light should have enough power reserves to support long-term continuous operation without quickly running out of power and causing inconvenience or even danger. Generally speaking, Ni-MH rechargeable batteries are more durable and environmentally friendly than ordinary dry batteries, and they are also easier to maintain and manage. Of course, regular inspection and replacement of aging damaged parts can not be ignored if you want to extend the life of the entire equipment.

With the progress of science and technology, more and more intelligent elements are beginning to be integrated into traditional emergency lamps, giving them more possibilities. For example, the automatic induction switch will light up immediately when detecting that the ambient light intensity is lower than the set value, thus eliminating the trouble of manual operation and improving the convenience and response speed. There are also some high-end models equipped with USB interfaces that can be directly used to temporarily charge small electronic devices such as mobile phones and tablets to solve the urgent need.

Last but not least is the question of price. All kinds of emergency lights on the market from tens of yuan to thousands of yuan are dazzling and difficult to choose. In fact, as long as the budget is reasonably allocated according to its own actual situation, it can select products with extremely high cost performance to meet the needs of daily life without wasting money and over-investing unnecessary additional functions.
