Picture :

Features:

1.High brightness : Adopt SMD5630 with each LED 22-23lm, drive current is 60mA, while the

SMD5630 Max driver current is 150mA. only 40% of Max current.which is better for longer lifetime and lumen loss.
The other suppliers usually use Epistar SMD3528 with each led 6.5~7lm, drive current 18mA

for working,while the Max drive current for Epistar SMD3528 is 20mA. 

2. Chip Size

Chip size for SMD5630 is 20*44mils=880mils.
Chips size for Epistar SMD3528 is 8*10mils=80mils.

3.Aluminum PCB board

High heat conductor of aluminum PCB, much easier for heat output 

4.Less decay

Small current for leds light source and best aluminum PCB, 5000hours in temperature testing no decay.

5000hours in 50degrees temperature testing, less than 2% decay. 

5.Soft-start protection devices, easy avoid impact to transient current on led
