LED lighting (light emitting diode) is very much the future of domestic household illumination. LED lights for home have many advantages over regular incandescent bulbs, most crucially that it cuts electricity by up to 60%.
Another huge difference between LED and conventional lights is that conventional systems expend 98% of their energy in heat, which is obviously not needed and can be dangerous. Conventional lights also diffuse light in all directions. They are thus very wasteful. The LED, on the other hand, does not convert the energy to heat and is cool to the touch. This light converts all its energy into illumination and diffuses light in one direction.
The other difference is cost. LEDs cost almost nothing to run and last an incredible three decades plus. The cost of running an LED illumination will never even exceed the cost of the bulb in the first place. Contrast this with non-LED bulbs which cost more than 500 times the price of the bulb to run and to replace.
The conventional incandescent bulb is very fragile and easy to break. LED lights for home on the other hand, are tough, and will not break easily. They are also safer as they do not contain the dangerous element mercury which is present in some other lighting. Thus they do not pose a health risk and can be easily disposed of without any special precautions being taken. They also do not radiate harmful rays like infrared or ultraviolet radiation.
There are four big pluses for using LED: zero fire risk, energy efficiency, low cost and focused light. They make an ideal replacement for the ubiquitous halogen lights which are so wasteful of energy, run hot and are so much more expensive.
Because they are cool to the touch, these bulbs are ideal for illuminating within cupboards, wardrobes and beneath kitchen units. They can easily be installed and often give much better illumination than conventional lighting. Mood lighting is very easy using LEDs. These definitely are able to produce a range of colours which can be blended to create any mood you please in any room in the home.
An LED throws clean bright light in a particular direction and is ideal for desk and reading lamps. These lights might seem to require a big initial outlay, but they will pay for themselves in between one to two years. Replace one bulb at a time in places where you use the light the most, and you will soon get your money back in savings on electricity bills. Also start replacing lights where you do not need high illumination. Older generation LED lights were dimmer, but are still marvelous at saving on electricity and cost a fraction of the price of the new generation LED bulbs. They can be left on for long periods of time for negligible cost.
There is worldwide a policy of phasing out incandescent bulbs which is scheduled to be completed in the next couple of years. The future of lighting is obviously in low energy LED lights for home.
