1. Look at the number of heads, the number of heads should be moderate. Households usually do not exceed 12 heads. The batteries used are preferably 2 to 3 cells. If they are bigger, they will be a little wasteful. You can decide on your own for other special needs. Of course, high-power Hight Power LED flashlights usually cannot reach the number of 12.

2. Look at the welding, the welding must be firm. Each diode is connected to the circuit board by soldering. If there is a weak solder connection, it may cause the bulb to not shine or affect the overall application.

3. Looking at the battery, there are two types: general battery and lithium battery. Although lithium battery is a rechargeable battery, its life is low, about 2 years, and the life of LED is about 10 years. You can choose according to the actual situation.

4. Look at the brightness. A good LED flashlight has high brightness and slow decay speed.

5. Looking at the light bulb, it is difficult to distinguish the quality of the light bulb with the naked eye when the light bulb is calm, and the consistency of the light bulb can be seen when it is lit.

6. Look at the waterproof, a good LED flashlight has a waterproof function, good shock resistance, that is, it is resistant to falling. Because it is classified as an electronic product, there is a circuit board in the front of the flashlight. Once water enters, it is easy to short-circuit and cause damage.

7. Look at the aperture. The aperture of a good LED flashlight is a uniform circle, and the light spot of a poor LED flashlight is unevenly distributed in yellow and blue. Try to gather a little on the condensing surface of the electric beads. This kind of flashlight is not able to adjust the focal length like ordinary flashlights, so be careful not to have astigmatism when purchasing.

8. Looking at the appearance, you can choose an aluminum alloy shell, which is beautiful and generous.

9. Look at the appearance, according to the detailed application occasion and purpose, you can choose the corresponding flashlight of moderate size.
