Light Bulb Replacements

LoveOO writes Boston.com has a story about three companies which are trying to replace the Light bulb. I say it's about time and what about hydrogen powered vehicles? Two things that annoy me are filling the gas tank and changing light bulbs. It's time we did alot less of both."

    OK. So how much time are you spending changing light bulbs per year? And was the total time spent submitting this news story longer?

    To be honest I don't think that changing light bulbs is a major household time sink. (Different story of course for people who deal with traffic lights, and hence the move to LEDs). I must spend minutes per year changing light bulbs, I waste far more time replying to /. articles complaining about people worrying about optimizing the wrong sort of time wasting activities. Oh wait...

      Not much. But if regular bulbs everywhere would be replaced by less energy-consuming alternatives... there's a point to it, especially when you concider the recent news.

  2. Heard of Flourescence? by jeffmeden · · Score: 4, Insightful

    I don't know about you, but im realizing the same benefits as they claim you get from LEDs, but my bulbs cost a whopping $2 for a lamp bulb and $3 for a fixture bulb. Flourescent! Cheap, no heat, hard(er) to break. Think about it.

  3. The thing is... by Sheetrock · · Score: 4, Insightful
    If you do the math, the regular old light bulb is still most efficient overall when compared to fluorescents or neobulbs. The amount of energy, resources, and pollution that goes into something has to be taken into account if you're really looking at reducing your impact on the environment.

    Additionally, you can't go wrong with nuclear power if you're looking at least polluting power sources. Many people look at solar as if its some sort of panacea, but the amount of energy that goes into making a tile is far more than you'll ever get out of it -- turns out that at the end of the day the thing everybody's been complaining about is the best option because all the pollution is contained.

  4. The problem is cost by toddestan · · Score: 5, Insightful

    The thing is, no matter how cheap they make LED lightbulbs, I doubt they'll ever get as cheap as the incandescent bulb, as the incandescent bulb is just plain out cheaper to make as it is much more simple. Therefore, the Wal-mart crowds will still buy the standard bulbs for years to come.

    What they should do if they want people to adopt these new bulbs is make it so all lightbulb packages have to display the average cost of the lightbulb over its lifetime. People may see that the LED or flourescent lights sitting on the shelf right now cost a lot more and don't buy them, but I bet they will when they see on the box that the bulb over it's lifetime costs a fraction as much in electricity used.

  5. We already have a good lightbulb replacement... by cmowire · · Score: 3, Insightful

    Florescent lights work just fine, are more efficent (especially if you want white light) than incandescent bulbs or LEDs, and are cheap and well developed in comparison.

    They've got a whole spectrum of colored tubes using the same technology as they use to make neon signs, if you so desire.

    The only thing that you get with LEDs is the ability to get small amounts of light from very small amounts of power.

    They are great for microlights and flashlights and medium-sized jumbotrons and a few special purpose applications where normal lights just won't work. The LED manufacturers are getting sick of just making indicator lights, so they are trying to push their new toys as much as they can.

    Unclear to me how this constitutes patent abuse. If someone is investing major resources in R&D and coming up with nonobvious inventions, it seems entirely proper for that person to seek patent protection.

  7. Re:Hydrogen - The future of Buzzword Energy by EmagGeek · · Score: 4, Insightful

    Ahh, good point, but you ahve to admit that it DOES HELP to move the combustion phase farther up the chain - because a power company can use oil or coal much more efficiently than your car can. A gas-fired power plant that produces hydrogen will probably be 5 or so times more efficient than your car is at extracting energy from fuel.

  8. Change the light bulb socket too by Malc · · Score: 3, Insightful

    Personally I think they should switch the socket to the spring-loaded bayonet style used in countries like Britain. I intensely dislike the normal screw sockets her in N. America. So much more effort, and I've had a few occasions were the glass unscrewed and left the metal base jammed in the socket (corroded or just double-threaded). I don't think the extra strength of the screw sockets is really worth it.

  9. Re:Patent abusing scum by 26199 · · Score: 3, Insightful

    No -- they're investing major resources in lawyers. Read the article... you do not need 100 patents on controlling LEDs, nor do you need two full-time patent lawyers in a 75-employee company.

    I would be surprised if more than one or two of those patents is nonobvious; certainly the major one mentioned in the article (blending LED colors to make -- gasp -- many different colors) is obvious. Even the author of the article complained about it.

    So. Yeah. Producing (and therefore consuming) hydrogen adds to the net level of CO.

    ...is to reduce consumption.

    Partly, to do with people using their cars unnecesarily, but also to do with how we transport goods. Production of many products is centralised, and then requires huge transportation costs.

    The USA produces I think about 20% of the world's pollution. How much could you reduce this if people walked more and stopped driving huge SUVs?

  13. Not exactly.... by raygundan · · Score: 5, Insightful

    I keep seeing people say this, but it just isn't true. The reason stuff from the 50's seems to be well-built and last forever is because the crap is already broken and gone. All that's left is the good stuff. In another 53 years, nobody will remember the $40 VCRs that died in two years. But there will be people hanging onto commercial video-editing decks that really were built to last. And everyone will run around saying things like "i wish they built things as well as they did back in 2003!"

  14. An excercise for the poster... by raygundan · · Score: 3, Insightful

    1. Find out how many edison bulbs were manufactured, ever.

    2. Find out how many are still working.

    3. Grab a calculator, and do some quick math to figure out what percentage that is.

    But seriously-- there are going to be counterexamples on both sides. Some things today are made to break. Some things back then were made well. The converse to both is also true. But the trend is still valid. Crap breaks and goes away, good stuff (AND bad stuff that was waaaaaay out on the edge of the bell curve for reliability) lasts long enough for people to mistakenly assume everything comtemporary to it was well made.

    I think you failed to think things through all the way with your post. If Edison bulbs were good, and lasted this long, they are exactly the sort of thing I was referring to.. If they had broken, and been forgotten about, you would have posted about something else that still worked as an example of "good things from back then." Your dad's slide rule, maybe-- or a microscope you bought at an antique store.
