Description
LED Light rings are small pre-built PCBs with a number of LEDs installed onboard. This high-density LED ring is made of a thin aluminum PCB, and tolerates heat better than traditional PCBs. The thin profile also makes it perfect for accent lighting, back lighting, and other uses. On the board are two rings of LEDs with a warm white inner ring and standard white on the outer perimeter. This is done to allow for selectable color temperature, and with adjustable control, can be used to vary the color temperature between the two extremes. Common 5V power is applied to the Red wire, while Black and White are connected to ground (or your low side switching MOSFET).
