How to choose high-power High Quality Led Flashlight?
look at the light bulb
1. Look at the number of heads, the number of heads should be moderate. Household use generally does not exceed 12 heads, and it is better to use 2 to 3 batteries. If it is larger, it will be a bit wasteful. For other special needs, you can determine it yourself according to your needs. Of course, high-power High Power LED flashlights generally cannot reach the number of 12.
2. Look at the brightness. A good LED flashlight has high brightness and slow decay speed.
3. Look at the light bulb. It is difficult for the naked eye to distinguish whether it is good or bad when it is off. You can see the consistency of the light bulb when it is on.
4. Look at the aperture, the aperture of a good LED flashlight is a uniform circle, and the light spots of a poor LED flashlight are divided into yellow and blue and unevenly distributed.

When purchasing, you should pay attention not to have astigmatism.
Two internal structure
1. Look at the welding, the welding should be firm. Each diode is connected to the circuit board by soldering. If there is a bad soldering connection, it may cause the bead to not light up or affect the overall use.
2. Look at the battery, there are two kinds of ordinary batteries and lithium batteries. Although lithium batteries are rechargeable batteries, their lifespan is short, about 2 years, and the lifespan of LEDs is about 10 years. You can choose according to the actual situation.
Three external structures
1. Look at waterproof. A good LED flashlight has waterproof function and good shock resistance, that is, it is resistant to falling. Because it is an electronic product, there is a circuit board in the front of the flashlight, and once water enters, it is easy to short circuit and cause damage.
2. Look at the appearance, you can choose the aluminum alloy shell, which is beautiful and generous.
3. Look at the shape, and according to the specific use occasion and purpose, you can choose a flashlight with a moderate size.
