The end of incandescent bulbs?

  1. I heard that all incandescent bulbs will quit being produced and illegal to sell
    in 2013. Is that true? I've also heard that some bulbs like the Par 38 outdoor
    spots and floods might continue to be available. Is that true? Someone said they
    thought pretty much all halogen bulbs will still be available... Can someone
    there tell me what the truth actually is? What about entertainment bulbs, like
    Par 64s and 56s, and aircraft landing lights...???
     
  2. I heard that all incandescent bulbs will quit being
    No. Only 100W bulbs. Lower-wattage conventional bulbs will be gradually
    phased out.

    Decorative and special-purpose bulbs (such as those used to light ovens and
    refrigerators) will be around for a long time.

    In order to answer those questions one would need crystal balls, mine
    are brass.

  4. You can get 101 watt bulbs ;)

    cheers
     
  5. AHHHH! What about my Lava Lamp!!??

    Good point. Stock up on the bulbs you need.

    I have two Giants. I think they take 100W bulbs.

    Geez, I can just see the black market in light bulbs... go to the guy on
    the corner, he takes you into an alley, you look over the wares, buy
    something... hope it's not burned out already... hope the police don't
    stop you along the way and search you...

    I can get you a 100 W for only sixty bucks!

    I watched the Blu-ray last night. You wouldn't believe it, but it's
    /gorgeous/ -- apparently from the composite negative. Biroc's lighting has
    rich shadows, and creates the appropriate atmosphere for each scene. The
    Blu-ray is so much better than any other version I've seen, that I have to
    unreservedly recommend it.
     
  9. I wasn't "aware" of Biroc, but his work goes back to It's a Wonderful Life.

    I bet the Jello looks good on blu-ray.

    I have 100 100s and >200 60s. That's stock for home use.

    I guess I picked the wrong week to quit incandescence.

    I've seen odd numbers like that with heavy service bulbs, and the like.
    Basically, they have a heavier filament...
     
  13. I saw some 71 watt incandescents for sale. They were
    There are such things as 75W bulbs, so replacing one with a 71W bulb will
    save you 100Wh every 25 hours of operation. If the bulb is on all the time,
    you'd save about $3.50 in electricity a year.
    Actually, for a given light output (notice the qualification!!!), heavy-duty
    bulbs (like the 130V bulbs installed in hard-to-get-to places, such as
    garage-door openers) waste energy. The lower the temperature of the
    filament, the less visible light is produced. (This is covered in just about
    any physics book.) But the bulb lasts longer, as the life of an incandescent
    bulb varies as the 12th power (!!!) of the applied voltage.

    This is why tungsten-halogen bulbs produce more light than regular
    incandescents. The bulb can run hotter, because the halogen cycle (whichfilament.

    The catch is that you have to leave the bulb on for a while for this to
    occur -- you can't be constantly turning it on and off. And if you use a
    dimmer, you can't dim the bulb "just a bit", because you'll halt the halogen
    cycle, without meaningfully lowering the filament's temperature. (I've seen
    this.) To paraphrase Pope... "A >>little<< dimming is a dangerous thing. Dim
