How do you know that?
You've asked about a transistor that has a number that fits no
standard, and yet does fit the sort of number you see on proprietary
parts.
You want some, but can't find them.
You'll settle for an equivalent, but don't know any.
You haven't told us anything about why this transistor is so important
to you.
That all adds up to a strong indication that it is a house number.
You know more about it than us, yet you are having trouble finding it.
That's a good clue about something.

As far as I understand what goes on there, around 10-15 watts is
I believe some who are not aware that the lumen is a unit of luminousI think when Cree talk of lumens per watt, they're talking of lumens
for each watt of electrical input, and that's how I want to make the
comparison.
I was only mentioning figures of lumens per watt of visible light
output
to explain that an incandescent achieving 17.1 lumens per input watt
is nearly 7% efficient.
Put 100 watts into an incandescent that chieves 17.1 lpw. You get
1710
lumens. Each lumen is about 1/250 watt of "white light", not the
1/683 watt assumed by those claiming incandescents are only 1-2%
efficient.
I've managed unintentionally to get you to say that three times now.
I'm not always quick on the uptake, but I try... what I'm getting at, is
can any other evaluation result in that lower figure? I'm not convinced
that taking only the lumens at 555 nm accounts for this. Lumens seem
slippery enough if they depend on spectra and photopic sensitivity anyway.
Wikipedia again:
"In photometry, luminous flux or luminous power is the measure of the
perceived power of light. It differs from radiant flux, the measure of the
total power of light emitted, in that luminous flux is adjusted to reflect
the varying sensitivity of the human eye to different wavelengths of
light."
I expect about 6.7 watts in the case of a 1710 lumen 100W incandescent,

Is there a really, really detailed schematic with guaranteed output

around 700mV above the negative rail at 1mA, one BE drop of Q13 plus the
saturation voltage (or close to it) of Q12. But no "hard" data anywhere.
You don't like page 4 ?
Nope, they only give one value there, how much current it is guaranteed
to drive when at 2V above the rail (10mA). Then uA value stated for
200mV isn't too useful, it just confirms that the current source
outlined in the schematic actually made it into production ;-)
10mA is pretty much at the point where the output device loses it. Not a
terribly useful piece of information.
WHY are you using an LM324... CHEAPSKATE ?
Umm, yes, that would be correct. Also the sheer number of suppliers, no
single-sourced parts around here unless there really is a compelling
reason. And usually there isn't a compelling reason.
All LM324's are not made the same. Remember my blacklisting Motorola?
I don't remember. What did their LM324 do to you?
Extreme distortion. Reeked havoc with active filters.
That sure explains the label printer.BTW my Barricade needed a few power cycles over the last week. Not good.
Yep, Mine got like that more and more often over time.
I've read that some of the heat sinks in there are on the skimpy side,
at least I'll open it before I give it up. Mostly because of that LPT port.
What did you buy to replace yours?
Linksys BEFSR81
I've got a Cisco wireless here (I believe same brand as Linksys) that
also has a few CAT-5 ports so I can use it as backup should the SMC
croak on a busy workday. I try to have a backup for pretty much anything
essential.
Tried a firmware upgrade before?
Yes. It was current, yet erratic :-(
Some firmwares supposedly could choke up when incomplete or deliberately
mutilated packets arrived, requiring a power cycle. At least that's what
I've read.
Of
course the real cheapskate fix would be to plug it into a timer that
turns it off for an hour after midnight
Yep.
Unfortunately I am going to need that printer port in there ...
Linksys makes a printer switch but, since the printers were wearing
out too, I bought printers with network ports... hp LaserJet 2015dn
and hp OfficeJet Pro K850.
Got one of those as well (Brother MFC). Also has fax, copier and scanner
in there. The sheet feeder is really nice. Every year I had to copy a
huge stack of papers before giving them to my CPA, in case they get
lost. Now it's really easy: Put stack in MFC, hit scan to file button on
PC, go do something else. No waste of paper and 15 minutes later it's
all in one PDF file. Sweet.

That's kind of disappointing. Those routers used to be on the pricier
side, metal case, no wall wart and all that.

it from the service because a severe storm was coming in and I had just
got cable internet.. I went to work, my step son got home and thought he
was mighty smart!. I had other adapters there in the same area
unplugged. He didn't bother to look or care if they were correct of not,
all he wanted was the internet.. So, my first unit was a 5 volt DC
wallwart unit. I had a 12 AC wall wart there unplugged. so you can guess
which one went into the router.
Of course, it was all my fault which it usually is. I can say with
confidence, that boy does not share my gene pool.
The one I have now uses a 12 volt AC wallwart and the PSU is internal

Mine dried up and lost value... Caused unstable supply.
