These power LED stars offer an extremely high light output in an energy efficient way. The power LED comes mounted on to special PCB star that acts to draw heat away from the LED, therefore extending it operational life. This makes them perfect for many lighting applications, a datasheet can be viewed detailing a few applications. Forward Voltage: 3.5V - 4.0V Angle: 110deg Luminous Intensity: 67000mCd Colour Temp: 6000K - 7000K
