These small 1.8mm LEDs give a great light and uses only a small amount of power to do so.
They are available in a range of colours, brightness, wavelengths, viewing angles and lens styles. The small size of these LEDs do not restrict where they can be used. deal for through panel applications where a small but reliable light source is needed.
In model railways they can be used to illuminate buildings, or can even be made into locomotive or rolling tail or head lights.
A light emitting diode (LED) is a basic semiconductor device that converts electrical energy into light.
