메모: the internal constant current circuit is provided. It only needs 3-5v power supply at the wire end to work. A 3.7V lithium battery can be used for power supply during the test

Product design features:
1. Good heat dissipation structure design, the best combination of copper and aluminum, smaller volume, better heat dissipation, meet long-term working conditions;
2. The built-in 3-5v constant current drive circuit is adopted, and the power can be constant when 3-5v is input. The integrated design of light source and circuit is realized;
3. With the external focusing design, the rotating head seat can realize the light spot size of different distances and meet the requirements of different working distances;
4. The wires are made of high quality silicone wire on the market. You don't need to worry about the wire damage when welding with electric iron.
