LEDs are available in a variety of sizes and shapes including the 3mm LED. We carry a wide assortment of the most common models of 3mm, 5mm, 8mm and 10mm models.
The size refers to the outside diameter of the LED. 3mm LEDs are the smallest and used in tight-fitting applications, while 8mm and 10mm models are used where you want to get out as much light as possible.
Super bright 3mm LEDs are extremely bright good for use in your projects, illuminations, head lamps, spotlights, car lighting, models.
3mm LEDs can be used anywhere where you need low power, high intensity reliable lighting or indication. They go easily into a breadboard and will add that extra zing to your project.
