1. Voltage: our LED beads use low-voltage power supply, the power supply voltage is between 2-4V, depending on the product, so it is driven by a higher voltage power supply; Safer power supply, especially for public places;

2. Current: the working current is 0-15mA, and the brightness becomes brighter with the increase of current

3. Efficiency: Energy consumption is 80% less than that of incandescent lamps with the same light efficiency.

4. Applicability: very small, each unit LED small piece is 3-5mm square, so can be prepared into a variety of LED lamp bead shape device, and suitable for variable environment.

5. Response time: the response time of its incandescent lamp is millisecond, and the response time of our LED lamp is nanosecond.

6. Environmental pollution: no harmful metal mercury.

7 color: change the current can change color, light emitting diode easily through chemical modification method, adjust the material band structure and band gap, to achieve red, yellow, green, blue and orange multi-color light. For example, when the current is low, the LED is red, as the current increases, it can turn orange, yellow, and finally green.
