This is a high-quality 1 Watt SMD LED. These LED's consume very low power and emit much intense bright light. There is a built-in heat sink at the bottom. This Led is suitable for PWM and it is fully dimmable. The LED Bead is the fundamental element of a high-power LED module. The Bead is designed to be mounted to a heat-conducting surface to draw away excess heat from the LED. See our complete assortment of LED Bead aluminium base plate, heat sink, and accessories.
They are extremely bright, many times more than a 5mm LED, and generally produce a wide angle of light disbursement which can be narrowed through the use of an external lense.
