The diode of an LED flashlight is not the highest in the entire cost. But the outer shell is made of magnesium aluminum alloy. The most important thing is the quantity and process. The products produced by large factories are more formal, with sufficient quantities and exquisite craftsmanship. And some small factories have very rough craftsmanship. LED also needs to control the current, otherwise it will easily burn out. So the selection of LED must pay attention to the above points.

LED, as an efficient lighting device, has continuously entered our lives. With the emergence of LED diode flashlights in previous years and the emergence of single lamp high-power 1W and 3W now, it continuously enriches everyone's choice of flashlights. Especially the emergence of metal flashlights made of aviation aluminum alloy has captivated many buyers. Of course, the price has dropped from the sky high. It is already very suitable for many, many buyers. The LED flashlight has dropped to over ten yuan per unit. The high-power single lamp is a new product with a relatively high price.
