Benefits of LED Lighting

Since the invention of the commercially practical filament lamp by Thomas Edison in 1879 the basic principal of generating light by heating a thin filament within a glass bulb has been refined in many ways however this basic , inefficient concept is still behind the majority of electric lights used in the world today.

In more recent times the fluorescent lamp has taken over many of the commercial lighting applications due to their relatively low consumption and longer life expectancy. In fact the current crop of Compact fluorescent lights (CFLs) being championed by governments as ideal replacements for 60 & 100 watt filament lamps are refinements of the humble fluorescent tube we have become so familiar with.

So if the new CFL products are the future do they have any real drawbacks, the answer to this is yes unfortunately they do. Complaints from users include that they take too long to reach they maximum brightness and that it is possible to see a high frequency flicker which can become very distracting and even dangerous to epilepsy suffers. To be fair the latest CFL offering have improved significantly in these areas however to date there is one major problem that won’t go away -  CFL’s contain mercury. The fact is that with the huge increase in the number of CFLs being used throughout the world we are creating a significant disposal problem for the future as managing waste mercury is very difficult.

So if the CFL is not the answer to our future lighting needs what is? – The answer to this comes in the form of the new generation of high power LED,which produce light as a direct result of a semiconductor reaction – much more efficient than heating a filament.

In fact on average LED lights consume only around 10% of the power of a filament or halogen light. They also have a long life, up to 10 years in normal usage. Plus when they do fail they can be recycled easily as they contain no hazardous elements.

With many manufacturers now packaging high power LEDs into the lamp styles we have become familiar with over the last few years, it is simple and for commercial and domestic users to consider the change to LED lighting. Whilst prices are higher than normal lamps, when the life expectancy and the reduced running costs are considered LED lamps should offer a quick return on investment.
