Choosing and Using LEDs

We sell LEDs in two sizes, three lens types and five colours.
The standard LEDs that you see in most projects are either 5mm or 3mm in diameter.
The lens (bulb) will be either clear or diffused.

Clear LEDs all look the same when off, but output a colour when powered (Red, Green, Blue, Yellow or White).

A Diffused LED most commonly means one that has the same colour lens when on or off, but are also available with all the lenses the same foggy white appearance when off, but coloured when on.
