What's an Ott?
Besides $25 for a 13 watt bulb.

A higher price brand with what I consider marketing hype.

Several years ago one of the then-regulars in sci.engr.lighting
published a spectrometer plot of one of those. It appeared to me typical
of a high color temperature triphosphor.

Just a couple months ago I got an Ott 13 watt twintube/"PL-style" at
Home Depot for about $10. That was a version for growing plants, and
supposedly has its spectrum as best as possible resembling that of
sunlight which Ott claimed was good for plants. My diffraction grating
tells me that this is indeed a "full spectrum" one, probably with color
rendering index probably in the low 90's, and the color temp. is about
5000K. However, other brands of fluorescents for growing plants have
their spectra running low in the green since plants reflect green
light and don't make much use of it, but best utilize red and blue.

OK, I am taking notes here.

Including one to myself to remind me that Otts have spread out from
the art and sewing markets. I am so not buying one at the art supply
store again! though at the time it was the least expensive source I
could find. I will mention that mine at least seems destined to live
forever. The bulb is now about 5 years old and still works fine.

Oddly, though Otts are supposed to be in the range of noontime
sunlight, they look cold to me. They work for color matching, but I
am not comfortable around them. They make my mastoids shiver and my
teeth wiggle, wish I could be more precise...

I suspect your lamp may be a 5000 or 5500 K unit, and sunlight with sun
at zenith in clear air is supposedly something like 5300-5400 K. I have
seen eyeball estimate as high as about 5000 K in Philadelphia.

But at typical home illumination levels, 5000 K typically looks icy
cold. Regular cool white is 4100-4300 K, and that often looks dreary in
home use. Even high color rendering index lamps with color temperature
4100 K can look a little dreary to most people in home use.

My interest lies primarily in accurate color reproduction.
Most often I do not know what the lighting in the area in which a
painting will be displayed is, or if it will change. Thus
approximating natural light is wise when creating it.
Something other than an Ott that will not bankrupt me to try would be
good. So I have been following along in this thread and gleaning.

The following fluorescent lamps have color rendering index in the low
90's and color temperature 5000 K:

Philips "Natural Sunshine" (available at Home Depot, possibly is the
same thing as Colortone 50)
Philips "Colortone 50" - color rendering index is 92
"Chroma 50" (I forget who makes that - maybe GE?)

The following fluorescent lamp has color rendering index of 98 and color
temp. of 5000 K: Philips TL950 (F17T8 and F32T8 sizes only)

Keep in mind that light output of a fluorescent tends to be compromised
when the color rendering index gets past 86.

Reread the comment that got me wondering. The implication was

using the vibration and keeps ringing long enough until
climax? hmmm...I suppose those cameras are getting used already..

They could be in the same room at the time...

I suppose they could but that's no fun. When you
have the real thing, why settle for a substitute?

That was my basis when I tried to figure out how
these phone matters could be arranged.

Arrange a date with her, where she goes to a classy restaurant
with the phone in her crotch. Make the call, and _then_ walk in
and join her, to watch. (Remember that Meg Ryan/Billy Crystal
thing? Well, this theoretically wouldn't be faked.) ;-)

Be sure she's charged her phone battery completely. ;-)

Yes and no. Cellular telephones do not cause
explosions. Sitting in your car then getting out will
build a static electric charge in you. Grabbing the
filling nozzle can discharge the electricity, generate
a spark at the filling port, and ignite gasoline fumes.
This scenario has been recorded on video surveillance
tapes at gas stations.

I once drew about a 2" spark (arc?) from my hand to the parking
valet's hand as I handed over my keys. I had forgot to hold onto
the metal door frame while I got out of the car.

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!

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.

Mother Earth is going to do whatever Mother Earth chooses to do, and

about the cyclic solar variations, orbital perturbations, and so on,
but Uncle Al seems to think that if he was dictator of the planet, he

What he said was carefully crafted to give the

plausible deniability. Therefore he is a liar.

And what are we to make of the people who insist on distorting

Not at all, I imagine it would go with either very nicely.

Sure.

The following was for a generous serving for one person.

Chop 1/2 medium size onion fairly finely and 'sweat' in a large frying pan with
vegetable oil, ideally olive oil, on a lowish heat.

After about 5-8 mins add 1 chopped small yellow pepper and 1 chopped small red
pepper.

Add ~ 1 clove garlic and a verly light spinkling of mixed Italian herbs. I
'cheat' and use garlic puree btw.

Continue to sweat until the veg become very slightly soft.

If you have available ( I did ), chop several pieces of sun dried tomato into
pieces ~ 1cm sq and add to the pan. You can also get sun dried tomato as puree
too btw.

Lastly add ~ 1/2 16 oz ? can of peeled plum tomatos ( with the juice ) and allow
to simmer very gently until of the consistency you like. You can also add a
small amount of concentrated tomato puree for slightly more 'tang' btw.

Check for flavour. If the peppers were very fresh it may be quite sweet already.
You can also add some brown sugar to taste ( try a teaspoonful initially ).

Serve on fresh pasta ( or indeed rice or couscous ).
