What are LEDs?
An LED is a Light Emitting Diode - a semiconductor used to create light. LEDs are bright, cheap, safe and long-lasting source of light.
Advantages of LEDs
-LEDs consume very little power, making them an energy efficient source of light-consume less than 6-8W
-LEDs generate very little heat and are cool to the touch.
-LEDs have an incredible long life span compared to other sources of light –up to 50 000 hours
-LEDs are very durable and will not break.
-Highest lumens output, up to 57 lumens/watt of system performance
-Environmental friendly, does not produce greenhouse emissions, does not contain mercury, toxins or other in organics.
-Instant ‘ON’ to 100% brightness
-Dimmable by regular wall dimmers/optional/
Benefits of LEDs versus Traditional incandescent lighting and Halogen bulb
LEDs are solid state technology and use lens instead of glass bulbs and filaments used by incandescent lights. This provides a much more durable lighting solution than incandescent bulbs.
LEDs produce less heat and generate far more light per unit of energy than incandescent bulbs, making LEDs safer and more energy efficient source of light.
LEDs do not abruptly burn out and unlike incandescent lights, if one LED goes out, the rest stay lit.
These bulbs directly replace your standard halogen bulbs but last many times longer and use much less electricity.
The whole idea of an LED light bulb is to save money in the long term. These have excellent energy efficiency and extremely long operating life a very high life span of up to 50.000 hours per unit with minimal degradation of light output whereas the halogen equivalent has only 5.000 hours life span.
Most halogen light when in use, often causing burns if touched accidentally, because of high temperature they reached. These LED units operate far cooler. They create negligible heat and can last up to 15 times longer than halogen equivalents.
These LED are the best possible quality-aluminum alloy lamp frame, stainless steel fastener and cool beam for safe touching. It is characterized by a very low degeneration and an extreme luminosity. This LED has the highest lumen/Watt relationship.
As a result of the small current consumption of only 3W and the long life span an efficient current saving already arises after a relatively short time. Because the lamps last longer, maintenance is virtually eliminated.

At present replacing existing inefficient incandescent light bulbs with CFL bulbs is the best way to reducing wastage of electricity, and to save money. However, recent developments in LED technology have brought the day closer when LED light bulbs will be cheap and efficient enough to make them common in homes and offices. They are already the best energy efficient option for spotlights offering longevity, reliability, and financial benefits, and they do not contain the mercury found in CFL's (see Toxic Mercury in CFL Bulbs.)

LED Light Bulbs
LED's are very cheap to manufacture, are very efficient, and typically last for around 50,000 to 100,000 hours (5-10 years continuous use) which is far in excess of CFL and incandescent light bulbs. However LED bulbs suffer from one major disadvantage: Each individual LED sends light out in a very straight line whereas an incandescent or CFL bulb sends light out equally in all directions.

Therefore an LED bulb must be made up of a large number of individual LEDs pointing in different directions; and even then, they are still only really suitable for directional (spot)lights and for mood lighting (rather than for full room general lighting) - i.e. they work best as spotlights over kitchen work surfaces or a desk, but will not light a living room adequately.

240V LED spotlights can be used to replace existing halogen spotlights and downlighters with fantastic energy savings (as direct replacements for standard GU10 based bulbs). A 25 Watt halogen spotlight for example can be replaced with a 2 Watt LED spot light bulb saving electricity and also running far cooler than its halogen equivalent. The LED spotlight bulb will also last many times longer than the halogen bulb which will make up for the initial extra expense.

Note that LED spotlight bulbs can typically NOT be used with dimmer circuits. Attempting to use a dimmer with an LED bulb will considerably shorten its life - i.e. to 10 minutes instead of 10 years.

The Colour of 240V White LED Spotlights
The light from LED spotlights is very different from the warm colour provided by the halogen bulbs that they are designed to replace. It is either very white, or white with quite a strong bluish tinge (particularly with the cheaper quality white LED spotlight bulbs) which can take a little getting used to.
