1. Voltage: LED uses a low-voltage power supply, the power supply voltage is between 6-24V, depending on the product, so it is a safer power supply than using a high-voltage power supply, especially suitable for public places.

2. Efficiency: LED consumes 80% less energy than incandescent lamps with the same light efficiency.

3. Applicability: The LED is very small, each unit LED small piece is 3-5mm square, so it can be prepared into various shapes of devices, and suitable for volatile environments.

4. Stability: LED can be used for 100,000 hours, and the light decay is 50% of the initial.

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

6. Drive: LED can be driven by low-voltage direct current, with the advantages of small load and weak interference, and low requirements for the use of the environment.

7. High color rendering: LED color rendering is high, will not cause harm to people's eyes.
