Some technologies have advanced very quickly over the years and especially in the last fifty but one in particular has not been thought about very much in industrial and scientific circles until we started to think about the carbon footprint and the costs to our pocket and our planet. The technology in question is artificial lighting. We have seen a slow progression from torches to candles to oil lamps and finally to electric incandescent electric light bulbs in the 19th century.
For a very long time the regular bulb was burning lots and lots of energy all over the globe and only a small percentage of that went into the actual light. The rest is dispersed through heat. A step forward was the introduction of neon and the creation of the first fluorescent lights. This has cut down cost and improved efficiency so much that the US, EU and many other countries around the world are phasing out light bulbs and instituting bans on sales.
But there is also an even more efficient alternative that is now taking over the market, led gu10 sockets and light bulbs. They utilize the electroluminescence phenomenon used in light emitting diodes. The same technology that is used in LED screens is now applied to the regular light bulb in the form of the led gu10, just like the tech needed for fluorescent lighting is also used in plasma television sets. Led gu10 is a bulb with a bayonet mount which is easy to use.
