the 100W bulb lives on....

Are lotteries mandatory? They are a tax (on the stupid).

No, but the lottery lines at the stores show considerable participation.
I think the thought of winning something makes it mandatory for some
individuals.

So, you're saying that the lottery (instituted by the State) is
voluntary taxation? If so, I agree. I also think it is a regressive sort
of taxation.

Yes.

Regressive? The odds are the same no matter how much you make. Well, the
odds are pretty low that you're playing the lottery, if you're rich. It's
still 100% voluntary. What's not to like?

Well, the poor should spend their money supporting their children,
wives, parents, themselves, etc. rather than blowing it on low
probability income.

However, it is their right to do so. And, their freedom to do so is
mandated by the State.

I guess I have no argument.

The poor shouldn't have wives or children. What free people do is none of my
business (unless they're getting my tax dollars).

Exactly.

I guess I have no argument.

Darn! ;-)

Maybe, but I haven't tried it yet. Here's an example. The bid is 94
cents with shipping at $8.90, or maybe $1 per 1 watt LED at 80LM.

http://cgi.ebay.com/Y-10pcs-1Watt-White-LED-80LM-1W-High-Power-Super-
Bright-/120750405542?pt=LH_DefaultDomain_0&hash=item1c1d48f7a6


I plan to use an existing table lamp and replace the bulb with a 5
inch diameter circular copper clad PC board to mount the LEDs. 20
square inches should be enough to dissipate 8 watts. That's about half
a watt per square inch.

At 350 mA, 70-80 lumens, with forward voltage drop of 3.2-3.4 volts.

(100 lumens and more at 100 mA at similar or slightly lower voltage are
available from Mouser, Digi-Key and Future, but at higher prices)

This means 70-80 lumens at 1.12-1.19 watts. Yes, it is common practice
to call such LEDs "1-watt LEDs".

This means 59-71.4 lumens/watt. This is not counting losses in whatever
is used to control the current through the LEDs.

Color temperature is stated as 6000-6500 K - sounds to me like a usual
icy color white LED. Color rendering index is probably usual of LEDs of
such color and efficiency, which has usually been said to be 70, maybe 75.
(I have seen a few closer to 80.)

In comparison, home lighting usually "wants" color temperature in the
range of 2700-3500 K and color rendering index at least 80, preferably
past 90. Getting color temperature lower than 4,000's to 5,000 K and
increasing CRI means less lumens out per watt in.

In the long term, a lot fewer. In the short term it isn't a
practicable propostion. One could - in theory - ban combustion engines
overnight, but if this draconian proposition were adopted it would
destroy society overnight, and with it, it's capacity to enforce any
such ban.

Which, of course, means Fred's statement ("You will not be
allowed ...") is invalid.

I don't know about "lefties", what ever they are (I assume it is a
political tag with which I am unfamiliar), but I have a mobile home with
such an arrangement. The dining, breakfast, living, kitchen areas are
all in such a combined "room". The bathrooms and bedrooms are separate.

Is that what you mean?

I had one of those once, and the only drawback was that I couldn't access
the hall closet and cook simultaneously. ;-)

Cheers!

That is one of the advantages of incandescent bulbs. The CRI is
100. The main reason women hate flourescent lighting.

In order for the 4000-6000 K lamps to be comfortable, sufficient
illumination levels should be used

http://en.wikipedia.org/wiki/Kruithof_curve

I have eight 18 W/950 (5000 K CRI > 90) fluorescent tubes illuminating
the white ceiling. I find it quite comfortable, especially in the
morning, when the increasing day light blends nicely with the
artificial light, without colour differences.

My guess is that you'll get a delta T of at least 50C.

No problem for me. I don't have a hall (closet) and I don't know how to
cook much.

One of the things I remember from my macroeconomics course is that poor
people are much more likely to play the lottery than the better off
people. In that respect, it is considered a regressive "tax."

I don't have the textbook any more, so I'll just have to trust my memory
on that.

Well me and the wife has Hall sex at times, she sticks her head in the
hall from one room while I reply in the hall from another room!, F**k,
yeah, Scr** you, Too!

Poor people make all sorts of irresponsible choices. That's why they're poor
but it doesn't change the definition of "choice".
I don't have the textbook any more, so I'll just have to trust my memory
on that.

Free will may be considered to be regressive by "progressives" but that's just
silly, like all their other "ideas".

prohibition was going to become absolute and all-embracing.

Goal post shifting. You said "a lot fewer" speaking of the
long run. Now you've changed to "absolute and all-embracing".

Nevertheless, you have nicely made the point, perhaps without
meaning to, that enacting whatever ban(s) Fred has in mind will be
influenced by more than whether an activity adversely affects the
environment. Whether a ban is practicable is one factor you
mentioned, and the impact of whatever ban is being considered
is another. When I asked the question of Fred, I had those
in mind, as well as some others.
