For the past century or so, we’ve grown accustomed to using incandescent bulbs in our house or even at workplace. Only in the past few years have we found some new choices in this category, with the ability to purchase compact fluorescent light bulbs (CFLs). Those were a little more expensive, but they lasted much longer than the light bulbs we were used to changing every year or so. And now, we have the ability to buy LED light bulbs, like the LED bulbs from Ikea, which sell for just under $5.
Incandescent Bulbs Weren’t Great For Mother NatureCFL Bulbs Still Aren’t as Good as LED Bulbs
Unfortunately, the news isn’t all good for CFL bulbs, since they do happen to contain a small amount of mercury in each bulb, which happens to be a serious neurotoxicant for adults and fish. That means disposing of them is a little trickier than just regular incandescent bulbs that just used regular filaments.
Granted, the amount of mercury inside a CFL is very tiny (smaller than the ball in a ball-point pen), but if CFL bulbs continue to be used worldwide, they’ll eventually put too much mercury into the atmosphere — which is not good.
LED Light Bulbs to the Rescue!
Back in the day LED light bulbs only emitted red light, which certainly limited their use. But now, they are available in ultra-violet and infrared spectrums, as well as visible light. That makes them usable in your house! They can now take the place of your incandescent bulbs and your CFL bulbs.
They have an amazing lifespan of 25,000 to 35,000 hours — about 20 times more efficient than incandescent bulbs, and twice as efficient as CFL bulbs!
Interestingly, LED light bulbs are also cool to the touch, since they don’t create light by using the energy in their heat.
The U.S. Department of Energy reports that over the next 20 years, with the adoption of LED bulbs over incandescent bulbs will prevent 40 new power plants from being constructed! It will generate more than $265 billion in energy savings and the electricity demanded to provide lightning in the country will be reduced by 33 percent!
Some of the problems with LEDs, however, is that they only produce light in one direction, which makes them not ideal for lamps or lights intended to light up an entire room.
Low-Cost Ikea LED Light Bulbs Make Them More Popular
Recently, Ikea LED bulbs have had their price cut for their 40W and 60W versions down to just below $5 each. That’s a welcome change for those hoping to live a greener life — while not breaking the bank.
Just a couple years ago, LED bulbs cost $25 to $100 per bulb, which made it much tougher to envision a world or a country trading out their cheaper CFL bulbs for LEDs.
While these initial bulbs have some diminished brightness and lower efficiency than some other LEDs, and they don’t come with a warranty, they’re still promising for the future of LED light bulbs in America.
