LED's are a revolution in lighting. They use very little energy, they hardly ever need changing and they contain no harmful mercury. 

In 2007 The Australian government began a gradual phase out of inefficient lighting products.  Most people would now be aware that you can no longer buy a regular incandescent light bulb at the supermarket or hardware store.  By October 2010 you'll no longer be able to buy 40W candle and fancy round bulbs, by 2012 even 25W candles and halogen par lamps will become a relic of the past.

By this time LED's will no longer be considered 'alternative' lighting, they will be the standard.

When making the change to LED's we need to shift our thinking from the idea that light bulbs are a low quality 'throwaway' item. High Power LED's are very high quality, robust, attractive appliances that give light. Think of them more as you would a light fitting because in many cases they will last just as long.
