Another is a direct constant

 Another is a direct constant current power supply, LED series or parallel operation. Its advantage  LED Downlights is low cost, but the flexibility is poor, but also to resolve an LED fault, does not affect the other LED running problem. These two forms coexist for some time. Multi-channel constant current output power supply would be better, in terms of cost and performance. Perhaps the future direction of the mainstream. LED Strip Lights

5. Surge protection LED anti-surge capacity is relatively poor, especially anti-reverse voltage capability. Is also very important to strengthen the protection in this regard. Some LED lights are installed in the outdoors, such as LED street lights. Due to the the grid load Kai rejection and lightning induction from the grid system will invade various surge some surge can cause damage to the LED. Therefore, LED driving power supply to have inhibitory surge intrusion, and the ability to protect the LED without being damaged. GU10 LED Lamp
