1. Looking at the battery, there are two kinds of ordinary battery and lithium battery. Although the lithium battery is a rechargeable battery, the life is low, about 2 years, and the life of the LED is about 10 years. You can choose according to the actual situation.
2. Look at the light bulb. When the light bulb is extinguished, it is difficult to distinguish it from the naked eye. You can see the consistency of the light bulb when it is lit.
3. Looking at the aperture, the aperture of a good LED flashlight is a uniform circle, and the poor LED flashlight spot is divided into yellow and blue unevenly distributed.
4. Look at the brightness. A good LED flashlight has high brightness and slow decay.
5. Looking at waterproof, a good LED flashlight has waterproof function and good shock resistance, that is, it is resistant to falling.
Look at the appearance, this is better than I can see, I won't say more. I chose the aluminum alloy shell, which is beautiful and elegant.
