Notes: 
1. The led lighting board need connect to suitable driver for it, It can not direct to Mains voltage AC 110V AC220V AC 277V or DC12V 24V 36V 48V 60V alone.
Driver requirement: input Voltage: DC 21V Current 600mA
2. LED PCB board lighting source Aluminum plate base board must be added with a heatsink or cooling fan. Most Aluminum and coper housing body is a good heatsink.
3. Ensure that the wire and LED welding temperature is below 85 °C Celsius
