1. The light source adopts imported high-brightness LED, which is energy-saving and efficient. The effective irradiation distance of type A can reach more than 250 meters, and the strong light and weak light can be freely converted.

2. Fully sealed design, waterproof up to 1 meter. The battery adopts high-capacity environmentally friendly lithium battery with long life and low self-discharge rate.

3. The shell is deeply anti-slip treatment, light and beautiful; in addition to hand-held, you can also use the tail lanyard to carry it by hand or a long rope on the shoulder.

4. The charging, discharging and constant current are controlled by chip intelligently, with multiple protections, which are safe and efficient.

How to choose LED flashlight

1. The number of heads is moderate. Generally, no more than 12 batteries should be used for household use. It is better to use 2 to 3 batteries. If it is too large, it will be a waste. For other special needs, you can determine it according to your needs.

2. Welding should be firm. Each diode is connected to the circuit board by soldering. If there is a bad solder connection, it may cause the electric beads not to light up or affect the overall use.

3. The condenser surface of the electric bead should be as concentrated as possible. Unlike ordinary torches, this kind of flashlight can adjust the focal length, so you should be careful not to have astigmatism when purchasing.

4. The contact of the power switch should be obvious. This kind of flashlight mostly uses a rotary switch, which is turned on when tightened, and turned off when loosened again. If the contact is not obvious, it is easy to cause the phenomenon of on and off.

5, pay attention to waterproof. Since it is an electronic product, there is a circuit board on the front of the flashlight, which is prone to short-circuit and damage once water enters.
