  • Introduction
  • Be it an industrial, commercial or a residential
    user, if an average user claims that nearly 5 of
    his income is being spent on paying energy bills,
    its really a matter of concern. Because, what
    appears is not always whats true. Before the
    invention of solid state lighting technology,
    nobody knew if we could save energy by just
    switching from one lighting technology to
    another. But now most of us know and that brings
    us to an understanding that LED lights and hence
    in this discussion, LED Cooler Lights are more
    energy-efficient.  
  • But you Might Ask, why are these LED Cooler
    Lights more Energy-efficient?
  • With new standards in lighting set by governments
    around the world, several measures were passed in
    favor of lights that were more energy-efficient
    and that later became a trend. The trend now
    continues with the lighting experts to improve
    ways in which LED lights can become more and more
    energy-efficient.
  • To that end, the LED Cooler Lights are more
    energy-efficient because of the following factors
  • The Working Principle of Traditional Fluorescents
    and LED Cooler Lights
  • And, The Power Draw By The Tubes - Traditional
    and LED Cooler Lights
  • Lets discuss the first one.
  • In order to better understand the working
    principle of LED Cooler Lights, lets first
    understand the same of fluorescent tubes.

In fluorescent tubes, where the current has to
pass through a gas conductor in the form of free
electrons and vaporize the mercury. When
electrons collide with the gaseous items of
mercury, free electrons are released which first
jump to higher levels and then fall back to
original levels. When they fall back to their
original state, photons of light is emitted. Now,
this light energy is in the for of UV which is
not visible to human eye so the same light which
when strikes the phosphor coating on the tube,
the same process of electrons being excited to
higher levels and then falling back to original
state is repeated, the difference just being that
now, its phosphor instead of mercury and photon
energy this time is now visible to the human
eye. Now, in order to start the fluorescent tube,
lot of free electrons and ions are needed to
allow flow of charge through the gas, which
unfortunately isnt the case and so for this
reason fluorescent tubes take too long to start.
Also, when they start, they warm up too soon.
Here is where, the fluorescent tubes waste lot of
light into heat. By contrast, LED Cooler Lights
use method where the light-emitting diode is a
 two-lead or p-n junction diode to which when
suitable voltage is applied, emits light when
activated. Here the voltage and the energy gaps
are engineered to be optimal and hence very less
energy gets wasted in comparison to fluorescent
tubes. We now come to the discussion on - The
Power Draw By The Tubes. Since, the fluorescent
tubes require extra power to start the tube, the
method that is most commonly used to supply that
extra power is making use of a starter switch and
a magnetic ballast. Now, whats the purpose the
starter switch?

The starter switch actually allows for preheating
of the tube so that less amount of voltage is
required in order to trigger the production of
electrons from the electrodes. On the other hand,
the function of ballasts is to limit the amount
of current that is being supplied to the tube. In
absence of both these starter switch and the
ballast, a very high amount of current would flow
to the tube directly, eventually allowing for
more heat production in the tube and waste of
significant energy into heat and not light.
  Now, coming on to the power draw by LED lights,
they do not require any ballast, the prominent
reason being they draw less power from the power
supply. In LED Cooler Lights, we have LEDs
drawing power from the driver instead of the
ballasts, though we do have compatible LED lights
that are compatible with the existing ballasts.
But, even in these compatible LED lighting
fixtures that are supposed to work through the
existing ballasts sooner or later come to fail.
These ballasts while they are working make the
LED Cooler Lights to draw more power from the
line source. Conclusion The two methods
discussed in the above sections clearly explain
as to why LED Cooler Lights would be more
energy-efficient than the fluorescent tubes. For
you as an user, savings in energy is worth
hundreds of dollars every month and so
energy-efficiency of any cooler light stands out
to be one of the most important criteria only
other than savings that is brought in any
lighting fixture through the use of dimmers,
timers and sensors.
