Are LED Lightbulbs Worth The High Cost?

The Republicans caved. In order to get the government spending bill passed, on Dec. 16, Republicans agreed to put on hold the implementation of a bill that would require more efficient light bulbs which, in the minds of many, meant the end of the much loved (and cheap) incandescent bulb. Proponents of the bill were quick to say that the incandescent bulb would still be available but in a more efficient form, and opponents argued that consumers should decide what kind of bulbs they buy instead of Congress.

According to the U.S. Department of Energy, consumers did decide. Energy and Commerce Secretary Fred Upton said, "We heard the message loud and clear from Americans who don't want government standards determining how they light their homes."

Americans are clearly opposed to the bill, but is it time we unshackle ourselves from the old incandescent bulbs and embrace new technology, and will our wallets thank us?

Is the Light Still Weird?
If you remember when compact florescent light bulbs first hit the market, the light they emitted was, for a lack of a more elegant term, weird. It was kind of green but also kind of white. It wasn't pleasing to the eye and as it warmed up, the light changed. This caused many to abandon the technology and go back to the incandescent bulb.

The new compact fluorescent bulbs are nearly indistinguishable from the old incandescent bulbs but once again, they're being abandoned for the new LED light bulb. LEDs power the new traffic lights, flashlights and TVs but now they can power your home and the light is described as a soft white light similar to incandescent bulbs.

The Calculations
Unless there's a good reason to purchase these bulbs, why pay the extra money? LED light bulbs are expensive. Prices start at $10 for a standard bulb and floodlights can cost as much as $100, but the cost of a bulb isn't as important as the money you pay to operate it.

First, let's assume that we're looking for the best way to produce 50,000 hours of light equal to an incandescent 100 watt light bulb. One, 100 watt incandescent bulb costs about 40 cents and to produce 50,000 hours of light, you'll need approximately 50 bulbs based on a life of 1,000 hours. That makes the cost of the bulbs about $20. Since an incandescent bulb requires 100 watts equal to 5,000 kilowatt hours of energy, that will cost more than $500 making the total approximate cost of our 50,000 hours of energy, $520.

Instead of 40 cents for the incandescent bulb, we had to pay $40 for the LED equivalent which, admittedly, is quite a case of sticker shock but to get 50,000 hours of light, we're only going to need two bulbs that use no more than 11 watts of energy equaling 540 kilowatt hours. The cost to power those bulbs is only about $58. Although we paid $80 up front, we had a total cost of only $138 or a 73% savings over the incandescent equivalent.

The Bottom Line
The above calculations will vary largely depending on the cost of the electricity as well as the current prices of light bulbs, but the cost savings of LED bulbs is clear. There's no doubt that the upfront cost of the more efficient bulbs is a stumbling block for some, if you can afford it, but the new LED bulbs offer a dramatic cost savings over the life of the bulb. How many light bulbs do you have in your home that could be replaced by LEDs?

    Doing your math and thinking ahead makes sense, but most Americans are bad at this. Why do you think so few have any money saved for retirement?
    • A Yahoo! User 4 months ago
      The lack of savings may be from a lack of living wage jobs in this country Garrett. A lot of folks are lucky to be making just over min. wage. You can not build for a retirement with that. Between you and I don't you think our gov. has done a great job with all these trade deals?

      Sorry we are only trying to help make long term thinking choices. Skip a few latte's.

    i will be replacing about half of my bulbs in the long run. i already have the CFC bulbs in about half of my fixtures after replacing the old style one at a time as they burn out. my idea stays the same but with LED in the future.
    • A Yahoo! User 4 months ago
      You aren't saving money waiting for incandescent bulbs to burn out. It only takes a few months (depending on amount of use; it's usually only 2 or 3) to amortize the
      cost of CFL replacements. It's actually better to throw away "good" incandescent bulbs than money.
    • A Yahoo! User 4 months ago
      i am sure that is true but i would rather wait to recycle the old bulbs.its just not in my personality to waste them. we will see. u definitely provided food for thought.thanks
  • A Yahoo! User  •  Holt, United States  •  4 months ago
    All 30 of my lights, indoors & out, have had LEDs for a year. 2 have burned out but I believe they were defective & I did return them w/no problem to Sam's Club. My only concern is that they seem to give off a very dim light when turned off, possibly using energy.
    • A Yahoo! User 4 months ago
      This is from the circuit driver. There is a capacitor in them that discharges very slowly through the LEDs. Light switches aren't dimmers; they don't allow *any* electricity through them when turned off.
    • A Yahoo! User 4 months ago
      Thanks, that is what I thought but when I unscrew them, there is no more dim light.?
  • A Yahoo! User  •  4 months ago
    The technology is new and the products are not being used enough to bring the costs down. Someday they will take over however!
    Until then; it is like a computer, wait until the price come down!
    CF bulbs are OK, but polute, they will go away and be replaced by LED!
    Engineering in the auto industry has been using LED for several years now. Any installation that has to be ver energy wise may consider them now. Such as low power solar off grid may consider the cost acceptable in order to keep the amps down for using other hi amp components.
  • A Yahoo! User  •  4 months ago
    Did they really say, that it takes two led bulbs to replace a 100 watt incandescent? At $45 each it's not worth it.
    • A Yahoo! User 4 months ago
      I'm pretty sure you can find them for less than $45. I have a lot of 40w & 60w replacements, only using around 3 & 5 watts, that only cost me $6-8 each. They were selling them in multi packs at Sam's Club.
  • A Yahoo! User  •  4 months ago
    My take on LED lights; first of all replacing critical lighting areas with LED decreases the amount of generator power needed when powering up during outages which are frequent where I live. In places such as bathrooms where FL lights go on and off before the bulbs heat up, they were going bad prematurely and often. I replaced all the eight bathroom vanity lights with LED’s and have eliminated that problem. LED’s can be purchased now in in different color ratings, so you don’t have that pure white light , which some like, but most don’t. I did some math and it looked good to me. I haven’t had to replace any LED’s yet, so time will tell. They do need to make more affordable choices that are brighter than a traditional 40wt. All my lanterns and flashlights are LED now, which save a lot of money on batteries.
  • A Yahoo! User  •  Surfside, United States  •  4 months ago
    One thing to note, though. Although I would definitely advocate LED lights myself, the calculations made in the article is a little manipulative. Using 50,000 hours hours of light as a baseline is a little ridiculous: If you turned on a light for about 4 hours a day, it would take over 30 years to hit 50,000 hours.
  • A Yahoo! User  •  Roanoke, United States  •  4 months ago
    I watch TV with an antenna. LED bulbs cause significant interference with reception of my weakest channel.
  • A Yahoo! User  •  Southfield, United States  •  4 months ago
    I hate the new lights. They may be bright but the light does not extend bast the bulb very far. I paid $4 for two night lights and they are bright right at the source but they do not eliminate the area around. Our community replaced our street lights. The beam of light is very bright shining straight down but its pitch black directly around that beam of light.. The old street lights lit up the intersection and half the street.. since they have been changed nearly all the neighbor have turned on their porch lights nightly. That just means more ppl are using energy not less. Same goes for flashlights. I bright beam that is not very helpful and traffic lights are harder to see, night time is the only time the color change is really noticeable. There best use is to spot light or on signs but not to light up an area like old bulb or florescents.
  • A Yahoo! User  •  Elmhurst, United States  •  4 months ago
    While LED's have improved, one application where they fail immensely is in a closed-globe light fixture. I'm guessing that the heat generated inside the globe is too much for the LED electronics to handle and the LED light bulb burns out after a very short period. I have had two LED bulbs burn out within the first month in that fixture, so avoid using them in any fixture that doesn't have sufficient ventilation.

      Buy from a better source. Not Home Depot or Costco. A real lighting store
  • A Yahoo! User  •  Seattle, United States  •  4 months ago
    You can take my U.S. made incandescent light bulbs (made by Aero Tech lighting, good for 27,000 hours) when you pry my dead, burnt fingers off them.
  • A Yahoo! User  •  Charlotte, United States  •  4 months ago
    I bought a lot of those florescent bulbs. Most of them failed. One blew up on me. I didn't get the five years out of them that was claimed I would get. I got a year or less. I bought incandescent bulbs to replace the florescent ones that failed. Now the industry wants me to spend a lot more money for LED bulbs. Yeah right. Fool me once. Keep the incandescent bulbs. They work better and are better for my economy. Plus, most people can't afford the expensive stuff. Same mentality as these hybrid cars. The mentality is, spend $30,000 on a new hybrid car and save on gas. Excuse me, I can buy a decent used car for $5000 and buy $25000 worth of gas over about 12 years. Even if gas prices went up, I'd still be ahead.
  • A Yahoo! User  •  Washington, United States  •  4 months ago
    I love the way they don't talk about the fact that LED's do fail and all it takes is one bad $100 LED bulb to make this whole thing "not worth it". (Go Green = Keep what you have and don't buy new....) Also notice that most people don't keep the house long enough for these "green" items to pay for themselves. All this "Go Green" is a marketing push to have use buy more...aka... upgraded to the "New" even if it is junk.
  • A Yahoo! User  •  Hemingford, United States  •  4 months ago
    About 8 years ago I replaced all of my light bulbs with compact florecent bulbs and I am very happy not having to climb on a step ladder every 2-3 weeks to change some bulb in the house. However I don't like the govt' telling me what light bulbs I have to use what bussness is it of there's what bulbs I use!!!
  • A Yahoo! User  •  Bristol, United States  •  4 months ago
    I just thought of something else. With the cost of the bulbs being so expensive these bulbs will be a target of thieves. Now you will have to be worried about them getting stolen. Nobody steals a 40 cent light bulb. I only pay 25 cents when you can get a pack of 4 at the Dollar Tree Store.
  • A Yahoo! User  •  Sacramento, United States  •  4 months ago
    THESE LED only save you money if they last the life of the bulb..And in most cases they never make it never the amount of time predicted,, IN many cases they only make it less then a year..And who keeps a bunch of receipts of lights bulbs around waiting to return them. .Its just a whole bunch of ______.ill wait until the price comes way down..
  • A Yahoo! User  •  Phoenix, United States  •  4 months ago
    I would have to refi my house to replace all the bulbs!
  • A Yahoo! User  •  Bristol, United States  •  4 months ago
    How many people can afford these light bulbs. This country is starting to look like a dictatorship. One more thing how do you put a lamp shade on one of these funny shaped bulbs. I don't know about you but I'm stocking up on the good old bulbs.
  • A Yahoo! User  •  Cleveland, United States  •  4 months ago
    I never buy bulbs! i just goto visit my parents and take my burned out bulbs! when they are not looking I take out their good bulbs and put in my burned out bulbs! they just think the bulbs burn out quick!!!!!!!!!!!
