This posts is talking about how energy companies are trying to decommission the old style light bulb which uses a heated element in a sealed glass dome which doesn't make the most of space we are familiar with LED's from various toys and gadgets we have all owned but now they are incorporating them into bulbs. This comes from the huge energy benefits that come from them that has been found to be true by the use of them in televisions. The led will last 10 times longer than the average bulb wont short out if there is a power cut or power surge and it a lot brighter and smaller and more compact to fit into the small modern day homes we live in today. These positive points aid the products in becoming more and more appealing because as they are now beginning to be introduced into retail stores if more people know the benefits and hows they are again coming onto the same trend more green they will buy them to save the planet and benefit from them themselves by reducing their energy bills further reducing their carbon footprint. These are uses in advertising on large scale displays because they are visible in sunlight are can create a lot brighter and more crisp images than traditional projection methods making ads more and more appealing and because LED's work on a grid they can be made on a huge scale. The only disadvantage to this technology is that they are extremely clear far away but up close they are just dots of light no matter now many LED's they use that's what should be considered when designing an ad more a led display even if you have the majority of them in a company colour then close up it can still be relevant to the ad they saw far away.
