What is an LED light?

What is an Incandescent Light?
Incandescent lights are the second oldest form of electric lighting.
They work by heating an electrical element until it is white hot and
can create light.Incandescent lights are an inefficient source of
lighting as almost all their energy is converted into heat, and little
have a low life span.
What is a Halogen Light?
Halogen emits light by passing electricity through its tungsten filament,
which is enclosed in a bulb containing halogen gas. Halogen lighting is
an extension of incandescent lighting, both are relatively small in size
and both are easily dimmable. Halogen is superior to incandescent lighting
as it lasts longer & offers a brighter, more vibrant light. However, they are
more expensive and radiate a huge amount of infrared heat, making the
lights a fire hazard as well as being an inefficient light source.

What is a Compact Fluorescent Light?
Compact fluorescent lights (CFLs) are miniature versions of full sized
fluorescents. CFLs produce their light by heating a gas, which can be
harmful to both the user and the environment. CFLs screw into standard
lamp sockets and offer a similar light to incandescent bulbs. Although
CFLs are energy efficient and often less expensive then other energy
efficient lights, they have many disadvantages. Firstly, they contain small
amounts of mercury, secondly, they have a flicker effect and unable to
turn on instantly and thirdly, they can produce a constant humming sound,
which can lead to headaches.
What is an LED light?
LEDs (an abbreviation for light emitting diodes) are solid state semiconductordevices. LEDs create light when their semiconductor crystal is stimulated.
This technology has been around since the 1960s and was first used in traffic
lights and alarm clocks. LEDs are much smaller in size than traditional light
bulbs and fit easily into electrical circuits. Recent technological advancements
have lead to LEDs being desirable for home, office and commercial lighting
spaces. Their extensive benefits include long life, superior energy efficiency,
generate very little heat, have low maintenance, low environmental impact,
instant light, easily dimmable, silent operation & low voltage power.
