LED Lightbulbs Made Easy
Every homeowner wants that all costs to be under control especially when talking about the electricity bill.
Homeowners are having having hard time thinking what to do to lower their bill and end up to use solar panels and create solar homes.
However, LED light bulbs are an easy choice for almost any homeowner. Replacing incandescent bulbs with LED light bulb with good brand in best stores in Phoenix will impact your energy use and cooling costs (especially if you happen to reside in the desert).
LED bulbs use less energy. Incandescent and halogen bulbs use a lot more energy and they get super hot. Up to 400°. That’s hot. Imagine several lights in a room all turned on while it’s 90° outside and your a/c is running. Talk about fighting against yourself! What if you could have all that light without the heat? Well, you can. All you need to do is swap out those old bulbs with LED light bulbs.
Now your home will be using systems that work in harmony rather than battling against each other.
Another noteworthy savings is the lifespan of LED vs incandescent and halogen. A good LED bulb can last 10 years.
In their January 25ht post in 2018 the Wilden Living Lab reported that going with the newer and more efficient bulbs can save a homeowner $26 per month.
The energy cost of running an old-fashioned incandescent bulb is six times higher than the new age LED brethren.
Scatter that across all of the bulbs in your home and you can spend that $26 somewhere else while decreasing your personal carbon impact on planet earth.
This may be the single easiest improvement that a homeowner can make to drastically decrease energy usage in their home.
All you out there who need some green-energy in your life; this is your chance. This is as simple as unscrewing all of the lightbulbs in your house and putting in new ones. This single tiny upgrade will do quite a bit towards greening up that footprint of yours and saving you money.
How are LEDs Different from Incandescents and CFLs?
Let’s look at the attributes of all three.
The CFL or Compact Fluorescent Lamp has been an option starting in the 1990’s. These are the strange looking bulbs that have a swirled glass tube that is filled with phosphors and small amounts of the highly toxic chemical known as mercury. This fact alone should put them towards the bottom of any sane person’s list. Somewhat redeeming qualities of this bulb are that they last 8 to 10 times longer than incandescent bulbs and they stay much cooler.
The incandescent (now cannot be legally sold). These are the old school light bulbs that Edison transformed the world for decades. The burn out quickly, suck up a ton of energy and get really hot. In fact, roughly 90% of the energy that passes through the filaments in an incandescent bulb is wasted as that energy is transformed into heat. The remaining 10% of the energy actually results in illuminating light.
Here’s a big differentiator. Incandescent bulbs last an average of 1,000 hours. Sounds like a good bit of illumination, right? Hold on. Things are about to get ugly for the ole incandescent bulb. CFLs last up to 5,000 hours, and LEDs last up to 50,000 hours.
Put another way LEDs last up to 50 times longer than incandescent bulbs and up to 20-30 times longer than CFLs and halogens.
Are All LED Bulbs the Same?
The short answer is: Nope. The abbreviated long answer (I know, oxymoron, right?) is that all LEDs are not the same. Here’s the rub. If you look at the packaging of an LED bulb it is required to have a government label called “Lighting Facts” on it. Lightbulbs have a color and brightness spectrum.
Lumens is the measurement of brightness. When looking at those lighting facts labels you will see the lumens number in the top right corner of the label. The higher the number the brighter the bulb. This number is far more telling than the old watts number. Watts tells us how much energy the bulb uses to create its brightness. Lumens tell us how bright a bulb is.
You might think that watts would be a fair way to measure a bulb’s brightness since it tells us how much power is consumed to create the level of brightness a bulb emits. The reason that this number is not so reliable for measuring brightness is that not all bulbs are made exactly the same. Different manufacturers construct their light bulbs uniquely. So one manufacturer’s 60-watt bulb may very well be obviously less bright than some competitors. This is why the lumens number is so important.
Light Spectrum Color
This is a big deal. It used to be that LEDs were mostly blue in color. So the transition of going from incandescent to LED was hard on some of us. We grew up with that soft warm light from an incandescent, and now they’re telling us how great these LED bulbs are. Many of us (me being one of them) hated the weird blue light. Too darned clinical looking. Not very homey.
So, here’s what’s happened now that LED technology has evolved. It’s gotten better. A lot better. Now we can choose from a wide spectrum of color. the warm tone at one end and the blue at the other.
The warm end of the spectrum is around 2,700 Kelvin and the blue (cool) side of is around 6,500 Kelvin. This number, along with the lumens number, is posted on the lighting facts sheet produced by the manufacturer.
