LED flashlight is composed of multiple diodes, and the color temperature is very high.

The visual experience is very bright, which is his characteristic. What's more, he is very energy-saving, and a 5th battery can last for more than ten hours. The other is the magnesium-aluminum alloy metal shell, which is compact, windproof, rainproof and corrosion-proof, and is suitable for outdoor use. But the biggest shortcoming of this product is that the irradiation distance is very small, generally twenty meters. When you are far away, you can't see clearly. The above is the shortcomings of this flashlight itself. The following are some small factories that have followed the production due to the large profits. The continuous decline in prices has caused the aluminum alloy material of the flashlight to decline and the weight is insufficient. bright. In fact, the diode of LED flashlight is not the highest in the entire cost. It is a magnesium alloy shell. The main thing is weight and craftsmanship. The big factories produce more regular products, with more weight, and the craftsmanship is very particular. And some small factories have rough craftsmanship. There are LEDs to control the current, otherwise it will burn out. Therefore, the choice of LED must pay attention to the above points. [5] In addition, the difference between LED multi-lamp and single lamp 1W, single lamp 1W is a new light source, very popular products abroad. This LED is mainly a lamp with high power design.

There is also a condenser. If the quality is good, it can illuminate more than 100 meters away. But the price is higher. The drive circuit is done well. The appearance is also very beautiful. And the metal oxide film used as a decorative surface. Wearable and durable. The choice of this product must depend on the process and workmanship and the size of the factory. Otherwise, the quality cannot be guaranteed. But the price is high.
