$50 for a federally mandated light bulb?

NEW YORK – Two leading makers of lighting products are showcasing LED bulbs that are bright enough to replace energy-guzzling 100-watt light bulbs set to disappear from stores in January.

Their demonstrations at the LightFair trade show in Philadelphia this week mean that brighter LED bulbs will likely go on sale next year, but after a government ban takes effect.

The new bulbs will also be expensive — about $50 each — so the development may not prevent consumers from hoarding traditional bulbs.

The technology in traditional "incandescent" bulbs is more than a century old. Such bulbs waste most of the electricity that feeds them, turning it into heat. The 100-watt bulb, in particular, produces so much heat that it's used in Hasbro's Easy-Bake Oven.

To encourage energy efficiency, Congress passed a law in 2007 mandating that bulbs producing 100 watts worth of light meet certain efficiency goals, starting in 2012. Conventional light bulbs don't meet those goals, so the law will prohibit making or importing them. The same rule will start apply to remaining bulbs 40 watts and above in 2014. Since January, California has already banned stores from restocking 100-watt incandescent bulbs.

Creating good alternatives to the light bulb has been more difficult than expected, especially for the very bright 100-watt bulbs. Part of the problem is that these new bulbs have to fit into lamps and ceiling fixtures designed for older technology.

Compact fluorescents are the most obvious replacement, but they have drawbacks. They contain a small amount of toxic mercury vapor, which is released if they break or are improperly thrown away. They last longer than traditional bulbs but not as long as LEDs. Brighter models are bulky and may not fit in existing fixtures.

Another new lighting technology, organic light-emitting diodes, or OLEDs, has had problems reaching mass production. OLEDs are glowing sheets or tiles, rather than pinprick light sources, as LEDs are. They're used as vibrant color screens for smartphones, particularly from Samsung Electronics Co.

But making OLEDs that are big, bright, cheap and long-lasting enough for use as light sources has proved difficult, in part because they use chemicals that are sensitive to oxygen and spoil unless sealed very carefully.

Acuity Brands Inc., an Atlanta-based maker of light fixtures, will be showing some OLED panels at the show. They will go on sale next year, but the price will likely make them technology showpieces rather than candidates for everyday lighting.

LEDs are efficient, durable and produced in great quantities, but they're still expensive. An LED bulb can contain a dozen light-emitting diodes, or tiny semiconductor chips, which cost about $1 each.

The big problem with LEDs is that although they don't produce as much heat as incandescent bulbs, the heat they do create shortens the lifespan and reduces the efficiency of the chips. Cramming a dozen chips together in a tight bulb-shaped package that fits in today's lamps and sockets makes the heat problem worse. The brighter the bulb, the bigger the problem is.

The most powerful pear-shaped LED bulbs in stores today — the kind that fits existing lamps — produce light equivalent to a 60-watt bulb, though there are more powerful ones for directional or flood lighting.

Osram Sylvania, a unit of Germany's Siemens AG, said it has overcome the heat problem and will be showing a pear-shaped 100-watt-equivalent LED bulb this week. It doesn't have a firm launch date, but it usually shows products about a year before they hit store shelves.

Lighting Sciences Group Corp., a Satellite Beach, Fla.-based company that specializes in LED lighting, will be showing several 100-watt-equivalent prototypes, including some that solve the problem of cooling the LEDs by using microscopic devices that move air over the chips, like miniature fans.

Before the 100-watters, there will be 75-watters on the shelves this year. Osram Sylvania will be selling them at Lowe's starting in July. Royal Philips Electronics NV, the world's biggest lighting maker, will have them in stores late this year for $40 to $45.

However, 60-watt bulbs are the big prize, since they're the most common. There are 425 million incandescent light bulbs in the 60-watt range in use in the U.S. today, said Zia Eftekhar, the head of Philips' North American lighting division. The energy savings that could be realized by replacing them with 10-watt LED bulbs is staggering.;_ylt=AsE3Gkdtse.WMyLRBM_sWOCs0NUE;_ylu=X3oDMTNqNzVocWJlBGFzc2V0A2FwLzIwMTEwNTE2L3VzX2xlZF9saWdodGluZwRjY29kZQNtb3N0cG9wdWxhcgRjcG9zAzgEcG9zAzUEcHQDaG9tZV9jb2tlBHNlYwN5bl9oZWFkbGluZV9saXN0BHNsawNs

  • LOL I saw this. That's ok, I'll have a nice big stash of regular light bulbs by the time they are no longer sold anywhere.

  • I have a huge stash of regular bulbs. I can't use the new ones, they give me terrible almost incapacitating headaches AND they don't work worth a crap in a room where a lot of light is needed as soon as you flip the switch.

  • Oh and $50 for a light bulb is a HUGE crock o'crap.


    Answer by yourspecialkid at 9:55 PM on May. 16, 2011

  • We have been stockpiling too. We have about 300 so far.

  • YOu get a HEADACHE? I don't think you should be blaming the bulb--it sounds like a real health issue.

    There will be NO this LINK. Its a conspiracy theory at best.

  • We generally have a fairly good stock of regular old light bulbs and plan to really stock up on 75 - 100 watts. We use them to keep the pipes from freezing in the pump house during the winter.

    Answer by meriana at 10:55 PM on May. 16, 2011

  • We're stocking up. I can handle only so much of the swirly ones, and the led are only good for certain things. I use regular bulbs in the barn, by the puter, and to read by. To be honest, I'm sitting here right now with a candle lit and I'm happy.

    Minnesota, I know a good many people who get headaches from both led and cfl bulbs, and if I already have a headache they definitely make mine worse. Because I'm allergic to both tylenol and motrin, those bulbs were a large part of my decision to quit working (especially in any office).

  • uhmmm, we all know what prohibit means, right? Well, the 1st word is "IF" but they all do all kinds of things with that progressive fuzzy Math they use...kwim?

    H.R. 6-89
    ‘‘(v) BACKSTOP REQUIREMENT.—If the Secretary
    fails to complete a rulemaking in accordance with clauses (i) through (iv) or if the final rule does not produce savings that are greater than or equal to the savings from a minimum efficacy standard of 45 lumens per watt, effective beginning January 1, 2020, the Secretary shall prohibit the sale of any general service lamp that does not meet a minimum efficacy standard of 45 lumens per watt."
