What does LED stand for?

The acronym LED stands for 'Light Emitting Diode'.  Nowadays it is more commonly used to describe a lamp that contains multiple LED chips and is a very energy saving light bulb.  So if someone told you that their house was now full of LEDs, they don't just have a few LED chips, they have a house full of LED light bulbs that are rated at A, A+ or A++ saving a lot of money compared to the older style incandescent light bulbs or halogen bulbs.

To put it in perspective, this is an Light Emitting Diode Chip:

This is an typical cheap LED light bulb (GU10) with lots of LED chips visible:

 

Nowadays the LED technology has moved on considerably from these and the LEDSmiths website contains many of the latest LED bulbs:

 
The Energizer Glass LED GU10 - Available in Dimmable

The new Philips Dimmable Filament Golf Ball LED

As you can see with these new LEDs you really can't tell much difference between the old light bulbs and the new ones except these newer LEDs can save up to 80% off your electricity bill.
