Need some big indicators? We are big fans of these huge 10mm diffused green LEDs. They are fairly bright so they can be seen in daytime, and from any angle. They go easily into a breadboard and will add that extra zing to your project.
Pack of 25 diffused green LEDs
565 nm wavelength
2.2-2.5V Forward Voltage, at 20mA current
1000 mcd typical brightness (green LEDs will appear brighter to us than other colors)
