You can diffuse the bright LED to get a soft, beautiful light using a variety of filters created from semi-transparent material, including tissue paper, thin fabrics, colored plastic, LEGOs or cotton balls.The bright LED features a half watt super bright LED that responds to incoming voltages. The more voltage it receives, the brighter it gets. The littleBits library features a variety of LED bits to bring your circuits to life, including the bright LED Bit.
