Nah - if you learn to light one properly, the deflagration front
is contained within millimeters of the mantle. ;-)
I have watched people fill the auto gas tank. Despite all warnings
I've seen men and women hanging onto a cigarette while doing so.
Americans ! They probably use cellphones while refuelling too.

Having watched the current misusage of those things, I would
not be surprised if they use them during sex.

/BAH

er ... um ... while I never have done so, someone did mention the fact
that they vibrate nicely!

They vibrate, too? Oh, good grief. I guess that would make
the term "phone sex" take on a whole new meaning.


Apparently one can do quite a bit of erotic teasing with a mere phone
call and not saying a word.

What is the purpose of those devices vibrating while you're
talking?

Not while talking. They can be set to vibrate instead of (or
before) ringing.

I knew that.

The vibrate mode is more discrete than some
gawd-awful ringer tunes.

Reread the comment that got me wondering. The implication was
that the phone was used as a dildo. So...either the female
knows when the male is calling and never answers to use it
or ...??? IOW, how does the male know that the female is
using the vibration and keeps ringing long enough until
climax? hmmm...I suppose those cameras are getting used already..

/BAH

I think i understand people with multiple cell phones now, 1 for talking,
one for pictures / video, and one more as just discussed. Hmmph, beepers
are cheaper.

SNIP stuff about people smoking at gas stations

Nah - gasoline doesn't ignite by cigarette - not even the vapor. I
saw some guy who was working on a gas tank; he had taken it out of
the car, and dumped all the gasoline into a 5 gal. bucket (it was
only about an inch or so deep.) He was smoking. I asked, "Is it true that
a cigarette won't light gas?" and he kind of sneered at me, and flicked
his stub into the bucket of gasoline. It went "Fsst!" and went out.

I didn't find out if he poured that quart or so of gasoline (with the
butt in it) back into the tank. ;-)

I know gasoline usually cannot be ignited by a cigarette, but the
temperature of the burning tobacco is not always the same! Also,
gasoline formulations vary, and so may the temperature required to ignite
the vapor.

On the other hand, diesel's vapors do not reach a flammable
concentration in ordinary situations - toss a burning match into a bucket
of diesel and it will go out. (Then again, I prefer to not bet my life
or lack of a hospital visit that the forces of Murphy's Law won't find a
way to make something go wrong.)


Well, it won't explode, but it will burn, albeit with a really dirty,
greasy, sooty orange flame.

And isn't it almost the same as kerosene? That certainly burns in a
lantern.

Cheers!
Rich

Actually aerosols between LEL and HEL of deisel or baking flour will
explode. Google for "grain mill explosion" if you do not trust me.

Thanks for that Alan.

I browsed eBay a bit longer and finally found the kind of thing I was
looking for. I could't have been looking hard enough before.

I found some CFLs at 30, 45 and 65 W

I'm sceptical that the 30W is really as bright as a normal 150W
incandescent myself, so I reckon I'll go for a 45W.

I also have found that the claimed equivalent brightness / output is about 1
size off.

True but irrelevant. The temperature of burning tobacco is always
enough to ignite gasoline vapors if the concentration is in the
proper range. That range will vary slightly with the formulation
of the gasoline, but not enough to be a significant factor.

What matters is the temperature of the gasoline, the temperature of
the air and how much ventilation you have. At ordinary room
temperature the concentration of the vapor above the liquid can
easily rise past the lower explosive limit. Inside a gas tank,
it will typically rise above the upper explosive limit so that
a spark inside of a gas tank may not explode it.

In the open air the concentration will not be stable but will
vary as the air circulates above the liquid.

Lots of people have been killed and houses burned down
doing exactly what some guy above did. He's an idiot
and so is anyone who believes that what he did was anything
other than extremely dangerous.

I did not know that.

I think this may be the type of lamp to which bah is referring:

Is this a recessed ceiling fixture? Those build up heat and are hard on

Philips did say that the 25 and the dimmable 23 are not rated for use in

[snip]

I can say where and when compact fluorescents appear to me prone to
short life:

1) When on-time is short. As I hear it, "standard conditions" for life
expectancy include 3 hours per start. So I expect a fair chance of short
life expectancy compared to incandescents in motion sensor lights,
closets, restrooms used mainly for short trips, and refrigerators.

2) Higher wattage CFL in small enclosed fixture, due to heat buildup.

3) If the CFL is a problem-prone one, such as (according to my
experience) 25 watt spirals of GE and LOA brands made around 2001, LOA
45 watt ones, and LOA "Q-Lites" from the early 1990's. Also I have seen
"dollar store" ones have a significant rate of spectacular infant
mortality, as well as never achieving claimed light output (sometimes
low by a factor of 3) and sometimes not achieving stated color.

4) I hear of a few complaints of the Commercial Electric 42 watt spiral
dying young when operated base-up. I suspect the problem here is heat.

- Don Klipstein (don@misty.com)

I gave two post-mortems earlier in this thread. Here's another:
MODEL: Commercial Electric compact fluorescent lamp (CFL) model
ES-20, SKU 738-703, 20watt 120V 60Hz-rated.

INTERNAL CONSTRUCTION: hefty TO-220 switching transistors, mounted on
heatsinks, 105oC-rated Nichicon reservoir cap.

FINDINGS: All power semis intact & operable. Cause of death: lamp
heater failure (one of two filaments, failed open).

So, in my environment, that's three of three failures, all due to
heater fatigue, YMMV. If you find premature failures with zapped
semiconductors, I'd suspect line transients.

Note: I operate some units base-up, but bare (no enclosure) to avoid
heat buildup.

Cheers,
James Arthur

The actual haogen bulb itself runs hotter and the other side of this is that they're
more commonly available in high wattages.

Halogens are 3x as efficient as some particularly inefficient
non-halogen incandescents, but are generally more efficient than
non-halogen incandescents by a much smaller margin.

When design voltage, wattage and life expactancy are equal, a halogen
usually produces 15-30% more light than a non-halogen (although data I
mention below includes an extreme of a 64% improvement).
When the halogen has life expectancy 2-3 times that of the non-halogen
incandescent of same wattage and voltage, the halogen has light output
usually improved by a smaller margin, sometimes not at all.

Data points:

Design voltage 120V wattage 60 watts:

Non-halogen designed for life expectancy 100 hours: 845-890 lumens
Non-halogen 60A/99, design life expectancy 2500 hours: 790 lumens
Non-hal. rough/industrial service, life 3500 hours: 585 lumens
(Part of the loss is from increased heat conduction from the
longer and more-gas-cooled, and multi-supported filament)

Philips Halogena, design life expectancy 3000 hours: 840-900 lumens
Sylvania Capsylite, average rated life 3000 hours: 960 lumens

Design voltage 120V wattage 100 watts:

Non-halogen designed to average 750 hours: 1670-1750 lumens
Non-halogen Philips 100A/99, designed to average 2500 hours: 1500 lumens
Non-halogen industrial service designed to last 3500 hours: 1175 lumens

Sylvania Capsylite (halogen): 1800-1880 lumens depending on when
you checked
Philips Halogena: 1670 lumens with 3000 hour life expectancy

Design voltage 120V wattage 300 watts:

GE incandescent of life expectancy 750 hours: 6200 lumens
Philips incandescent of life expectancy 750 hours: 6250-6300 lumens
Philips incandescent of life expectancy 2500 hours: 5060 lumens

Philips version of the usual 300W torchiere halogen: 6000 lumens

Design voltage in the 12V ballpark, wattage in the 10-27 watt range:

Type 93 12.8V 1.04 amp incandescent, design life 700 hours: 14 lumens/watt
(mean spherical candlepower 15)
Type 1156 12.8V 2.1 amp incandescent design life 1200 hours: 15 lumens/watt
(mean spherical candlepower 32)

10W 12V T3 bipin halogens: 150 lumens, 15 lumens per watt
20W 12V T3 bipin halogens: 350 lumens, 17.5 lumens per watt

That's only one example case here in the house. I've
been tracking this elsewhere around the home, because of that

out of a compact fluorescent as I do a similar-rated (in lumens)

and perhaps about half.

The presumed 3 hours on per start is real: for old time starter based

start" types. CFL lamps do not have the same issues.

2) Higher wattage CFL in small enclosed fixture, due to heat buildup.

can see outside. My parents should not be allowed to play
with halogen lamps.

Speaking of fluorescent lights,

Since the PHB is so cheap, I'm ass-u-me-ing that he's expecting a
significant savings on lighting.

LOL ! The world works in funny ways.

My only real objection to CFLs is theway - at least over here - that
their
equivalence to an incandescent buld is overstated.

I'm looking at replacing my kitchen ceiling lights but all the DIY
stores
are pushing
the halogen bulbs. Most are 25-50w each bulb which tends to mean
100-200w for the average 'set' considering my present old tube is about
30w
that makes these halogens very inefficient, so unless they are pushing
these
halogen
because they are expensive and 'blow' quite regularly compared to tubes
and incandescent bulbs, why are tehy pushing them.

Halogens operate at a high temperature so emit a very crisp white
light which is very good in the kitchen. I prefer halogens to
fluorescents pretty much everywhere.

My folks have a halogen lamp. When I'd visit them in the summer,
Dad would turn it on at night and the temp of room would increase
a LOT. I'd never use them; I'm too afraid of fire.

Halogens are more (about 3x more) efficient than standard tungsten
bulbs, so the room should be cooler. The fixtures can get hot
though. The halogens in standard bulb envelopes aren't hotter than
the standard bulbs.

I don't which part got hot. I just know that my head could
feel the heat. It was about 4' away. My father has a life-long
habit of draping the curtains up over the lampshade so he
can see outside. My parents should not be allowed to play
with halogen lamps.

Maybe for Xmas you could get him one of those pull cord things,
so he could just open them. ;-)

Cheers!
Rich

I should have been more specific. These are the sheers that he
flips up. I already gave them their present, medical insurance.

I like Al Gore's scifi movie, "An Inconvenient Truth" where he preaches
about the myth of global warming from the backseat of his armoured,
7mpg limousine.

Make sure you MISS the movie about the Marshall University football
team killed in a plane crash in 1970.

How can you make a movie about a plane full of jocks, flown by
Southern Airlines pilots who'd never landed at Huntington before?

They flew into the side of the mountain, forgetting that the airport
was on top ;-)

"Attack of the Killer Tomatoes!" was more interesting ;-)

Well, the tomatoes WERE better actors, after all. That is, before
they hit the sauce, of course. ;-)

That movie was produced by Steve Peace, whose later big production
(California Electricity Deregulation Act, written while he was a member
of the California Senate) was much more of a horror show, without any
(intentional) redeeming comedy.

Oh, GROAN! ;-)

I had a GF once, and when I rented "Amazon Women on the Moon" for movie
night, she had a snit fit because she assumed it was some kind of porno.

Women! Can't live with them, pass the beer nuts. ;-)

Only two, but I'll be damned if I know how they both got into that light
bulb.
