    Granted, it was 4 night light bulbs. But that was better than the name brand pack next to it selling for 2/$2.50.

    Otherwise I get CFL bulbs for $.99.

    • The electronics in a $.99 CFL must be really crusty.
      • by RealGene (1025017)
        Those prices are typically underwritten by the local electric utilities. They supply the bulbs to the retailer at below cost, and take the difference as investment in energy efficiency, getting tax credits in the process.
        CFLs are approaching actual retail prices below $2, but as the Marketing Eye of Sauron has fixed its gaze on LED, I wouldn't expect much more investment in CFL technology.

          There's a good reason people are looking so hard at LEDs rather than CFLs; LEDs are simply better technology. The best LEDs have much higher luminous efficacy than any fluorescent. For example, Cree is selling LED fixtures that put out around 125 lumen/watt vs. just under 100 lumen/watt for the best fluorescent lights. It's actually more lopsided than that sounds, because the LED figure includes all the losses, while the fluorescent is for light coming out of the tube, not the entire device, and it ignor

          • Plus it's nice that I can drop an LED bulb and instead of having to technically call a hazmat team to clean it up, I can pick it up and it still works fine.
          • by Russ1642 (1087959)

            Here's what I do. Go to the store and pick up a package of 100 W incandescents and look at the output in lumens. Then try to find an LED light that even comes close. The only ones that come close are gigantic and very expensive. They don't even fit in the fixtures.

            • Maybe you're not looking very hard. Typical incandescents get 16 lumens per Watt, CFLs get 60 lm/W. That means that your 100W incandescent would generate around 1600lm, and you'd need a 26W CFL for equivalent. That's not a round figure, but 25W is and a 10 second search tells me I can pick up 25W spiral CFLs which are about the same size as an incandescent for around £5.

              I was actually a bit surprised by those numbers (maybe Wikipedia is wrong?), because I found that the light level increased whe

              • Assuming they fit in the fixture I really like putting 100W equivalent CFLs into fixtures too. I had a bunch of ceiling lights rated at 40W. The room was quite dimly lit with incadenant (more of a mood light than a reading light). Replace those with 25W CFLs and the room is nice and bright, I save power and I'm well within the quoted rating for the fixture (how much of a safety factor that is I don't know but it also helps the fixtures not be so hot to the touch).

    • by Carewolf (581105)

      Mine was a modern LED bulb. At $4.95 I thought it was rather expensive.

  • I replaced the kitchen lights with LEDs. About $22 a pop. These are the larger lights, not the incandescent sized bulbs.


    • by bunratty (545641)
      My price point for LEDs is under $10. You can find them cheap on Amazon and the reviews help make sure you're not getting low-quality bulbs. I've bought some LED floodlights and some LED ceiling fan bulbs for under $10, and they've been great so far.
      • by Bigbutt (65939)

        In my case it was more of a "hmm, would this work better" and then getting the same ones so the kitchen looks right :) The lights are certainly brighter than the incandescent bulbs were and there are 6 of the floods so I'm reasonably sure I'm saving a few bucks on replacing them. $130 worth? That I don't know yet. :)

    Lots of people ask us whether we accept, or where to submit, poll ideas: the answers are a) of course! and b) use our submission form here: []

    Just note that it's a poll submission, and include 5-8 options for options :) If we select your poll idea, we may tweak the question, the answers, or both, but the more ideas the better.

    • Following on from the current poll: How long did your last energy saving bulb last ? 0-1 months; 2-4; 5-8; 9-14; 15-23; 2 years; 2-3 years; 4+ years

      The reason for the question is that they are supposed to last many years of typical usage - I do not get that out of most of them, some only last 6 months. I want to know if others find the same ?

      • by grahamwest (30174)

        Between 2 and 3 years but it did not fail, so I don't know how long it would've lasted. I replaced it with a higher wattage "daylight" bulb a few months ago. I really like the much-less-yellow look of the daylight bulbs now and I don't think I'd use any other hue.

  • My uncle gave each of his relatives a large variety pack of energy efficient light bulbs for Christmas. Not a bad gift actually. Not flashy, except for in a light emitting way.
  • by MrP- (45616)

    One of my last purchase was the Phillips Hue starter kit which was like $200. And then I think I got some generic 40W style white LED bulbs for about $16. But I haven't used them yet so I'll just ignore them and go with the Hue and say $200 so I voted "Cost $20 or more"

    The most recent bulb I replaced was the one in my oven. It had been burned out for years, but I decided to replace it when I was in there to replace a heating element. $4.50 for a tiny 40W bulb! I suppose a run-of-the-mill bulb isn't meant for use in a 500F environment, nor necessarily (in the U.S.) to be run from 2-phase power.

    Yes, it was an incandescent - this is one situation where energy efficiency in lighting is a rather moot point. Bulbs in refrigerators, on the other hand...

      Just so you know (and a lot of people get this mixed up), 120/240V in the U.S. is not 2-phase power (with the exception of one small hydroelectric served area of upstate NY, which actually has some relic 2-phase generators)! You are receiving single-phase power off a 3-phase transmission system (typically, one residential neighborhood will be on the same phase), with a center-tapped/center-grounded step-down transformer providing service to your home. "Split-phase" is a more appropriate nickname for a center-grounded single-phase electrical system.
    • Just bought a new fridge. It came with LED lighting throughout the fridge. Guess this is the direction Fridge lighting is going. I assume Ovens can do the same?

      • by AK Marc (707885)
        Incandescents work best in harsh environments. CFLs don't like cold, and CFLs and LEDs don't like heat. In an oven, they'd need to use a remote-light (set in a cooler part, and light piped up to the inside)
    • Bulbs in refrigerators, on the other hand...

      If you keep your refrigerator open for long enough to the incandescent bulb heat the inside, you kept the refrigerator open long enough to heat the entire room...

    • My dad just had to buy a new light bulb for his very high end home theater projector. He said the bulb was $1,500. I know you could buy a projector for that price, but his particular projector ranges in price from $10,000 to $30,000 depending on it makes sense to buy the replacement bulb.

    My most recent acquisition was 2 cfl lamps included in a free energy-saver kit from the city. Included was a water saver showerhead, water-saver nozzles for the kitchen & bathroom faucets & 2 cfl lamps. Not bad for free. 'Course if you break down my tax bill I figure those cfl lamps cost about $22.25 each.

    ... the last time I bought light bulbs. We're still working through our collection of 100W light bulbs. I'd like to switch to low energy ones, but we have to piss off the climate change liars somehow.

    Anyway, when I did buy them, I paid in sterling, not in these dollar thingies being quoted in the vote. It doesn't make it clear if it means Canadian dollars or Australian ones, and that would make the value different.

      Actually, it's safest to assume that slashdot thinks in US$ -- like all the ads we Canucks get from below 49. And oddly enough, in the current market, A$, C$, US$ and NZ$ are about as close to each other as I remember ever having seen them. You have to hit the Fijian Dollar, Hong Kong Dollar or Namibian Dollar to get really wild fluctuations.

    I swear converting from the incandescent to the LED style looks like the difference between the NCC-1701 and the NCC-1701D (reflector dish).
    Plus total cost of ownership will be lower (incl. energy used) if it lives anywhere near the quoted lifetime.

  • My computer's screens cast all the light I need, you insensitive clod!
  • Each new clearance light fixture that I bought last week for my 1977 pop-up trailer came with two #194 wedge-base bulbs. The light fixtures cost $4 each. The plastic must be worth something, so I said "under a dollar".
  • I converted my entire apartment to CFL approximately 10 years ago. I have moved once since then...when I did the conversion I saved all of the incandescent bulbs the apartment complex put there, and just put them back when I left and took my CFL's with me. I have about 8 incandescent bulbs under my sink for when I move again (the apartment doesn't get to keep my CFL bulbs). I've had to replace...1 CFL bulb since then. I am thinking about converting to LED's, but I haven't seen the need to replace perfec
  • I bought a couple $15 LED bulbs on Amazon almost 3 years ago. I haven't needed to buy any since then because they're still going strong and supposedly last a lifetime.

      They dim over time by a large amount. Most often seen in Christmas Lights. My daughter took a string of blue LED's and used them as a nightlight in her room. about 1/2 were totally dead in 6 months. The remainer were all over the map in brighness, but all were much dimmer compaired to a string stored for Christmas used for comparison.

    We renovated last year, and as part of it, we replaced all the light fittings in the house and changed all the globes to LEDs.

    The globes may have cost more, but they have a significantly lower energy consumption.

  • And bought every 100 Watt light bulb they had, a few bags worth.

    I felt proud of myself until it dawned on me why the $ would offer them at such a low price, they pop about once a month, but I still have lots left.

  • Broke down and bought a Cree white LED equivalent of 100W, daylight color temp, for my bedroom, because I needed something dimmable yet not generating so much waste heat as the halogen it replaced. Not a single complaint about it, although the dimmer I'm using is from Ikea and sometimes if it's up all the way the lamp flickers faintly until I turn it down a fraction. More a problem with the dimmer than the lamp so far as I'm concerned. If the lamp lasts for years I'll consider it to be a successful experime

    'twas a CFL, or more specifically a box of six at about $5 each. it took a while before I settled on a brand that lasted longer than six months.

    I have bought a few LED ones too - they have good emitters, but the cheap mains capacitors in the ballasts let them down, blowing after a relatively short period.

    I would still really like to see CFL and LED bulbs come out with separate ballasts. Then you can just replace the part that's failed.

    • Old CFLs (Lights of America) were separate ballast, and the ballast was good enough (if you were lucky) to last through 4 bulbs. They lost in the marketplace because of higher initial cost, and the difficulty in finding replacement bulbs was another disadvantage.

      With LEDs, the LEDs and their heatsinks are the expensive part and the part most likely to fail. Separation of ballast from LEDs does not make economic sense.

      • by Trogre (513942)

        My experience with LEDs is the opposite - the diodes outlast the ballast components, in particular the mains voltage capacitor.

  • I had to replace 2 33W CFL striplights recently. I could not believe how cheap they were - $4.50 (Australian, but that's almost equal to US) for two. How do they make them for that?
  • I bought a used lamp for $25 that came with two bulbs in it. But previous to that, the last time I acquired a light bulb separate from a device, it was free through my local utility's "order a free package of energy efficiency items!" program. It included two standard-base CFL bulbs, two candelabra base bulbs (ironically between ordering and getting delivery, we had replaced the last candelabra-bulb fixture in the house,) plus a low-flow water faucet attachment, and a couple other things I'm forgetting.


  • By chance, the last energy-saving light bulb that I've bought turned 1 year yesterday. It's a Philips 1055 lumens/13 watt LED that's roughly equivalent to a 75 watt incandescent. I had prevously been using a 800 lumens/15 watt CFL, but I thought it was too dim, and swapped it to our hallway. We have had mixed experiences with CFLs in our house. We found that in our dining room they would only last a few months, I think that they didn't like being turned on and off all the time and they were right in fro

  • I have a vacation rental property, and some of the bulbs are very hard to replace. I'm afraid that a tenant might try to do it and break the fixture. Also, they take R20 bulbs, and they tend to be expensive to begin with. So now I don't have to worry about the bulbs failing when I'm hundreds of miles away.

    I also swapped out the ancient dimmer, but I'm not sure if that was necessary.

    I'm very happy with the new bulbs. They're a bit whiter than the old ones, but they dim very nicely.

  • In the spring/summer of 2011, I bought a LED bulb from (or something like that) for what is now worth $300. I wanted to support the budding Bitcoin merchants, and that was the only thing they had I really needed. The bulb itself is still fine.
  • I'm right at $20 a bulb since the majority of bulbs in our house are in ceiling cans and on dimmer switches. Best bulb I've found are these [] . And I've found that with LED's you really should just use one brand/color so every time one bulb burns out I order a two pack to get ahead.
  • Would like to outfit my home with LED bulbs but the cost of swapping out all the bulbs in my home came in around $2,000.

    Could go with CFL for about $300 but they are pretty toxic if they break, causing brain damage and what not, especially for kids, so not ok with that.

    Anyone else replaced all their lighting with LED?

    • by Lispy (136512)

      I did it gradually once they wore out. Never looked back. But my tiny flat wasnt that much of an invest.

  • Cost $7 for two bulbs at AutoZone so I choose the $5+ option. I figure I bought 1 bulb for $7 and got a backup for free (so next time the blinker needs replacement I won't need to make another purchase).
  • Replaced the 3-way bulb in a lamp with a Cree LED 3-way bulb. They think very highly of their product... and price it accordingly. If it doesn't exhibit any issues I'll start converting all the CFLs I bought 5 or 6 years ago to LEDs as they need to be replaced.
  • I've been mostly buying LED's, expensive as hell ($12 for candelabra, $20 for flood, $7 for 60 watt) but so far so good, haven't had any of them burn out, I imagine they're saving me quite a bit in electricity. IF they last as long as they say they will (10+ years) they'll be well worth it, but we'll see of they live up to their claims better than those no good, useless, short lived, toxic piece of crap CFL bulbs.

If it's not in the computer, it doesn't exist.
