, the future of our planet's lighting needs. Here we
provide key information about the fast approaching wave of LED
technology that will ensure a bright, energy-efficient future for
Pakistan's homes and businesses.
Adapted from our friends at SYO Co.,
future of household lighting will be the wide-spread adoption and
use of the white energy-efficient LED light bulbs.
In the near future, white LED lighting applications will be
powerful and cheap enough to replace incandescent lighting for
everyday use in our homes, in street lights, outdoor signs, and
Below are some of the advantages of LED lighting:
Long Life Span
operational life of current white LED lamps is 50,000 hours.
This is 11 years of continuous operation, or 22 years of 50%
The long operation life of an LED lamp is a stark contrast to the
average life of an incandescent bulb, which is a mere 5,000
If the lighting device needs to be embedded into a very
inaccessible place, using LEDs would virtually eliminate the need
for routine bulb replacement.
key strength of LED lighting is
reduced power consumption.
When designed properly, an LED circuit will approach 80%
efficiency, which means 80% of the electrical energy is converted
to light energy. The remaining 20% is lost as the heat
Compare that with incandescent bulbs which operate at about 20%
efficiency (80% of the electrical energy is lost as heat).
In real money terms, if a 100 Watt incandescent bulb is used for 1
year, with an electrical cost of 10 cents/kilowatt hour, $88 will
be spent on electricity costs. Of the $88 expense, $70 will have
been used to heat the room, not light the room.
If an 80% efficient LED system had been used, the electricity cost
would be $23 per year - there would be a cost savings of $65 on
electricity during the year.
Realistically the cost savings would be higher as most incandescent
light bulbs blow out within a year and require replacements whereas
LED light bulbs can be used easily for a decade without burning
Pricing and Payback
main limitation to the adoption of white LED lighting as a lighting
standard is the current high cost of led bulbs.
Although the cost keeps going down, LED light
bulbs are still expensive.
Although LED's are expensive, the cost is recouped over time and in
energy cost savings.
Factor in that it is significantly cheaper to
maintain LED lights, the best value is for commercial use where
maintenance and replacement costs are expensive.
Office lights and factory lights for example,
are being switched over to LED’s in many cities.
In summary, with the development of LED technology, LED
Lighting will be the future in lighting.
And as always, Solar Systems Pakistan is your trusted provider of
