Lightbulbs that will give a lightbulb
Since electricity was discovered by Thomas Edison about 140
years ago people have used the incandescent lightbulb. Up to now most people
are still using the incandescent lightbulb despite new and improved lightbulbs
like the LED (light emitting diode) being brought on the market. The biggest
energy waster. One of the biggest
problems for people is to remember to switch off lights when they leave a room.
This is a big energy waster, but with LED the consequences of this common
mistake is much less. The advantages of LED lightbulbs compared to fluorescent
lightbulbs are immense.
The LED is a version of solid-state lightning.
Semiconductors turn electricity into light.
In past times LEDs were mainly used for indicator and traffic lights,
but has now evolved into every day household used lightning bulbs. LEDs last up
to 25 times longer than an incandescent lightbulb and use up to between 20%-25%
less energy (Energy.gov).
LEDs
The prices of LED lightbulbs could
vary from around R 200 per bulb and the cost of an average lightbulb is round
about R 15. This makes LEDs significantly a lot more expensive in the short
term, but in long term it hold so much advantages. You don’t have to change it
so often and you make up your money by the amount of electricity you save. It
is not guaranteed that you will earn your money back with LEDs compared to
average light bulbs (Lumi, n.d).
The whole sizes of the bulbs are
practically the same. With both available in all the different fittings. LEDs
and average bulbs both come in small carton boxes of minimum expense. LEDs
don’t give off heat. So LEDs cannot be used for the heating and lighting of
snake cages, breeding boxes for birds and a lot other uses. This is where the
use of average lightbulbs that give off heat with their high energy usage is
better suited than LEDs.
I will recommend the use of LEDs
in established buildings where the usage of lights is very high, because then
the power saving component of the bulb can play a role and reduce electricity
bills. It will also reduce the maintenance of the bulbs in terms of replacing
them. In houses where the lights are only used during night or for lights which
have minimum working hours, I would rather prefer the average incandescent
light bulbs.
