Light Emitting Diode (LED) and Compact Fluorescent Light (CFL) bulbs have made energy-saving at home and office possible.
A few years ago we only had one option when it came to light bulbs: incandescent bulbs that use so much energy to light up a room. Many countries are on a mission to phase out incandescent bulbs because they waste so much energy and don’t last long adding to the already overwhelming waste around the world.
But thanks to the new LED and CFL technology, you now don’t have to worry about staggering electricity bills or having to replace your bulbs ever so often.
So what makes LED and CFL unique?
CFL vs LED, which one should you buy?
Let’s take a deep look into this new and efficient way of lighting your home and all the variables you should take into account the next time you go shopping for a new bulb.
LED vs CFL: What is the difference?
CFLs and LEDs are indeed the two most popular new light bulb options available. To understand the two options better, let’s take a look at what makes them different and some of the advantages and disadvantages that come with each.
What are LED light bulbs?
Light Emitting Diodes commonly referred to as LEDs are extremely energy-efficient bulbs. LEDs are tiny semiconductors wrapped in protective plastic. The semiconductors have two terminals that allow the flow of current in one direction only.
Currents with a positive and negative charge come together and create energy released in the form of light. This mechanism creates a fast source of light that is reliable, instantaneous, and able to be dimmed.
What sets LEDs apart is their ability to last long. Statistics show that LED light bulbs can last between 20,000 to 50,000 hours. This is up to five times longer than any other bulb on the market.
When comparing LED vs fluorescent bulbs, one main difference is that LEDs produce directional light while incandescent bulbs spread the light more spherically. This means that LEDs need less energy to spread the light.
LEDs also do not cause heat build-up as compared to incandescent bulbs that get hot and contribute to heat build-up in a room. You, therefore, don’t need air conditioning in a room with an LED bulb.
The one major disadvantage of LEDs is that they are expensive to produce making them expensive to buy compared to other types of bulbs.
What are CFL light bulbs?
Now let’s compare LED bulbs vs CFL but first let’s see what CFLs are.
CFLs work by driving an electric current through a tube that contains argon and mercury vapor. This then creates an ultraviolet light that quickly translates into visible light.
When it comes to energy, CFLs use about 70% less energy than incandescent bulbs. They also last years longer than traditional bulbs.
There are two things that stand out when it comes to CFL vs LED bulbs. One, CLF bulb is cheaper than LED bulbs. Two, CLF bulbs are perfect for any type of lighting fixtures, unlike LEDs that don’t work so well with table lamps.
Unlike LEDs, CFL bulbs take a few minutes to warm up and reach full brightness. They also cannot be used with a dimmer switch.
A major drawback of modern CFLs is that they contain a small amount of mercury, which is still very harmful to both your health and the environment. CFLs should therefore not be disposed of in your regular household trash. This drawback is a major reason why LEDs are more popular than CFLs.
LED vs CLF Costs Compared
When replacing your light bulbs, the cost is most likely the first thing that will make you choose one bulb over the other. However, when it comes to energy efficiency, cheap is not always the better option. To get a clearer picture of what we mean, let’s take a look at how much it will cost you should you choose to buy an incandescent, LED, or CFL bulb.
Generally, an incandescent bulb is way cheaper than any other type of bulb. The average cost of an incandescent bulb is $1. But how about CFL vs LED cost? A CFL bulb is about $2 while an LED bulb is about $4.
So at the face of it, it’s cheaper to buy a CFL bulb than an LED one. However, if you put the longterm LED vs CFL savings, an LED bulb is the cheaper version.
It will cost you $211 to keep one 60-watt lamp lit with incandescent bulbs over a course of 20 years. If using CFL bulbs over the same period, you will part with $54. LED bulbs are even cheaper costing you just $34.
Remember, this is just the cost of lighting one lamp. So imagine how much you stand to save if you were to use LED bulbs for your entire house!
So as you can see, spending a bit of money on LED bulbs today can often lead to substantial savings in the long run.
LED vs CFL Comparison: Pros and Cons
Both LED and CLF bulbs come with a number of pros and cons. Here are some of the most significant ones:
- LEDs spread light in just one direction, unlike other bulbs that spread light and heat in every direction losing almost 50 percent of the light even before leaving the fixture.
- They light up immediately.
- They don’t heat up much. They stay cool to the touch even after use.
- They last for about 60,000 hours compared to the 1,000 hours of a traditional incandescent bulb and up to five times longer than CFLs.
- They are not sensitive to cold temperatures.
- Do not contain mercury and therefore easy to dispose of.
- One LED can prevent about half of a ton of greenhouse gas emissions in its lifetime.
- LEDs’ directional light that may not spread as evenly as other sources.
- They cost more than CFLs and other bulbs.
- They use 75 percent less energy than incandescent bulbs.
- They can last up to 10 times longer than incandescent bulbs.
- They cost less than LED light bulbs.
- They produce extremely bright light that spreads evenly.
- They produce less heat saving on cooling costs.
- They take a few minutes to heat up and reach full brightness.
- They contain mercury, a toxic heavy metal.
- They can be sensitive to cold temperatures.
Why We Recommend LED’s
A closer look at the differences between LED lights vs CFL and when you take into consideration the CFL vs LED cost it’s hard to beat the value offered by modern LEDs.
Even though they cost more than CFLs, LED bulbs last way longer, and therefore, in the long run, they end up costing less.
The use of mercury in CFL bulbs is another reason why LEDs are definitely the safer option. In addition, their instantaneous illumination and soft and warm white hues that mimic the glow of traditional incandescent bulbs, make them more efficient for your lighting needs!
