The end of incandescent bulbs?

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...???

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.

Not "all" incandescent light bulbs.

http://en.wikipedia.org/wiki/Phase-out_of_incandescent_light_bulbs
gives a reasonable overview.

The high points:

- The regs mandate a minimum lumens/watt requirement for bulbs in
various wattage ranges.

- The standards kick in over time... currently the U.S. standards for
100-watt bulbs will start applying in October of this year. Bulbs
of lesser wattages have later implementation dates... 40 watt bulbs
are the last ones to which this set of standards will apply (I
don't know the date). California has already implemented an
efficiency standard that has taken the standard 100-watt
incandescent bulbs off of the shelves, I believe.

- As I understand it, most halogen bulbs do meet the efficiency
requirements... a "100-watt equivalent" halogen bulb draws around
75 watts.

- "Light bulbs outside of this range are exempt from the restrictions.
Also exempt are several classes of specialty lights, including
appliance lamps, rough service bulbs, 3-way, colored lamps, stage
lighting, and plant lights."

- A second tier of restrictions is scheduled to become effective in
2020, which will require all "general-purpose' bulbs to deliver at
least 45 lumens per watt (CFL and LED would comply, incandescent
and halogen would not). "Exemptions from the Act include reflector
flood, 3-way, candelabra, colored, and other specialty bulbs".

There are other regulations, in various areas, having to do with lumen
efficiency for outdoor area lighting (e.g. parking lot lights). I
read one article in a trade journal recently which indicated that
almost all new commercial outdoor area lighting being bid for these
days is LED - the reduced electricity cost and reduced maintenance and
improved color rendering (compared to mercury or sodium vapor) is
making it the go-to choice.

You can get 101 watt bulbs ;)

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.

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 guess I picked the wrong week to quit incandescence.

I saw some 71 watt incandescents for sale. They were energy saver
types, but I didn't buy any. Where do they come up with a number like
71 watts?

I've seen odd numbers like that with heavy service bulbs, and the like.
Basically, they have a heavier filament...

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.
I've seen odd numbers like that with heavy service bulbs,
and the like. Basically, they have a heavier filament.

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
