What is the Difference Between LED & CFL Light Bulbs?
sure what type of bulb to replace it with. There are many different choices
at the store, but which bulb type will work best in your household and
meet your lighting needs? Two popular choices are LED light bulbs (light
emitting diodes) and CFL light bulbs (compact fluorescent lights). But,
which is better? We discuss the differences between LED light bulbs and
CFL light bulbs below.
LED Light Bulbs
Advantages of LED Lights
LED lights or light emitting diodes are an energy efficient light bulb
that is built to last for long periods of time. The average LED bulb has
a lifespan of 50,000 hours. That means the average LED bulb will burn
for approximately 5.5 years if left on 24 hours a day, seven days a week.
Assuming you don’t leave your lights on 24/7, LED lights will last
for a very, very long time. They also fit into any household lighting
fixture and do not require an adaptor. Unlike traditional, incandescent
light bulbs, LED lights do not blow, or burn out. Instead, their brightness
fades over time, and you should replace them when more lighting is needed.
LED lights are RoHS compliant, meaning there is no Lead, Cadmium, Mercury,
or other harmful elements found within the bulb.
Disadvantages of LED Lights
Although LED bulbs last an incredibly long time, they are more expensive
than CFL light bulbs. However, due to their longevity, they may be a cheaper,
long-term solution to CFL lighting.
Estimated Annual Operating Cost of LED Lights
The estimated annual operating cost of LED light bulbs is approximately
$33 per year.
CFL Light Bulbs
Advantages of CFL Lights
CFL lights bulbs (compact fluorescent lights) are another energy efficient
alternative to traditional incandescent bulbs. The average CFL bulbs has
a lifespan of 8,000 hours approximately a full year of 24/7 lighting capacity.
Although this is significantly less than LED bulbs, CFL lights should
still last for a couple of years. CFL bulbs emit light that more closely
resembles an incandescent bulb than LED lights and are less expensive
than LED bulbs. CFL lights can also fit into any household lamp or lighting fixture.
Disadvantages of CFL Lights
Although cheaper than LED, the lifespan of CFL light bulbs is merely a
fraction when compared to LED lighting. Perhaps one of the most significant
disadvantages of CFL lights is the amount of Mercury found inside the
bulb. Although the amount of Mercury found in the bulbs is minimal (approximately
1 5 milligrams), CFL light bulbs can be harmful if any Mercury makes contact
with humans or pets. Due to the Mercury, CFL lights are not RoHS compliant.
Estimated Annual Operating Cost of CFL Lights
The estimated annual operating cost of CFL light bulbs is approximately
$77 per year.
