LED lighting is the most significant development in the field of electrical lighting in the last few years. Only a few years ago businesses and households were paying a lot of money both in terms of electricity and for replacement light bulbs, the old incandescent type which although they were quite cheap did not last very long, had a high failure rate and were extremely inefficient.
The amount of energy these bulbs used was a real problem and it was for reasons of economy that many people opted for fluorescent lighting which was far cheaper to run although the colour of light was not so attractive compared to incandescent bulbs.
Fluorescent lighting has been around for decades but after some significant developments the fluorescent bulb evolved into the more energy efficient CFL bulb, which outclassed its rivals for energy usage, cost and reliability as well as producing a natural amber coloured light, which everybody prefers in contrast to the blueish cold light of traditional fluorescent tubes.
The latest development is LED lighting, which is even more efficient than CFL, which in itself was immensely popular. LED lights were originally only used as indicators on instrument and control panels, rather than proper space lighting but now they are produced in colours other than the traditional red and green and the most important development was the invention of the white led and then combining them in clusters with a reflector at the back, in sealed units.
These LED bulbs have by and large replaced the incandescent and CFL bulbs having a much brighter light and higher reliability while having fractional use of energy in comparison. They were a lot more expensive when they first appeared but now they are in massive production they have reduced in price and are in use just about everywhere. First they appeared as Christmas tree lights, then the first clustered designs came out used in the design of torches and flashlights.
As they were being made more powerful and in more durable enclosures they became more popular and their energy saving qualities and longevity made them extremely attractive to big businesses for industrial and commercial lighting.
Companies that changed over to LED lighting were seeing very significant savings in their lighting costs. LED light bulbs also produce very little in the way of heat so they are safer to use in many applications where this can be a problem.
LED lighting now saves us money, reduces energy usage and is safer all round in every application and due to their low power consumption they are ideal for use with solar power installations.
