Main technical indicators of LED light emitting diode:
1. Color temperature range 6000-6700K
2. Power 1W (single LED lamp)
3. Rated work current ≤ 300 mA
4. Current stability ≤ ± 2 mA (within 24 hours)
5. Brightness is between 70-90lm (left and right strictly symmetrical)

Electronic Protection：
1. High voltage protection
When the power supply voltage is ≥15.5V, the control part is automatically separated, and the LED lamp is directly powered by the external power supply to protect the control module from damage.
2. Low voltage protection
When the power supply voltage ≤ 9V, the LED lights are automatically turned off, and the system is protected.
3. Loss of frequency protection
When the control is frequency anomaly, the LED lights are automatically turned off to protect the control module and the LED lights.
4. Misconnection protection
When the three cables of the LED lamp, namely VBB (black power supply) VSS (ground Brown) VC (light reduction control Gray), are randomly misconnected without any damage to the circuit, and the wrong light is not on, the light will be on when the pair is connected, and it can be controlled by light reduction, which is very convenient to install.
