1.Linear constant current IC control, photoelectric integration design with stable performance, high reliability and long lifespan.

2.Over-voltage & over-current protection.

With optimized constant power IC design, when input voltage varies between AC 220 and 240V, the IC maintains constant power output within ±5% fluctuation range to protect the module from over-voltage and over-current.

3.Over-temperature protection design.

When the PCB rises up to a very high temperature after running for some time, the patented technology IC will automatically reduce the output current to control the temperature rising of the PCB.

4.High color rendering index. Ra of the module is > 80 with EMC standard SMT LED.

5.No EMI.

The module meets qualification standards of certification such as CE-EMC, CE-LVD, SAA, RoHS, PSE and UL.

6.No concern in ultraviolet ray or electromagnetic radiation.

7.Custom design and Manufacturing.

Customized service is available for custom PCB shape and size design, custom color temperature, custom LEDs and so on.
