that lamp is only 30000 lumens
I have another Lamp a 2Kw Sports stadium Lamp thats about 5 times as bright (id Post a picture but uhh I don't have any of it next to a mac LOL )

This is probably outside your area of interest, but I have a half dozen Mazda-base flashbulbs that are about the size and shape of a typical household lamp. I'm drawing a blank on the bulb number, but I know I looked up the specs on them and they are BRIGHT. These particular bulbs are among the ones O. Winston Link used for night time photos(although he used several hundred at a time).
I haven't had the inclination to touch one off-they are actually fairly valuable, and I'd hate to do it for no particular purpose.
Yeah Very bright but for less then a second
The Mazda name places them at pre 1945 as thats when GE dropped the Mazda name (I assume these are US Mazda ones right?) do they Have the Foil or Wire wool Magnesium fill?

Mine are magnesium wool.
They're not the big "grandaddy" GE bulb with foil that was made in WWII that(as I understand it) were made for photographing aircraft carriers.
I'm not sure if they are actually branded "Mazda"-that's just a habit I've gotten into for referencing the standard(in the US) lightbulb screw base. I'll dig them out and photograph them.
@bunnspecial the Foil type flash bulbs normally indicate an Older Flash bulb (1920-30s).
@weckart My bad the 2Kw metal halide lamp I have is 220000 Lumens I slightly under estimated it LOL

I had to dig them out. Turns out they are Syncro-Press #11s, and aren't quite as large as I remembered. They also do NOT have the Mazda branding on them.
Shown next to standard 60W screw-base bulb, and of course the 23" Hi-Res display and AEKII on my Quicksilver.
BTW, although they don't state output in lumens, the guide numbers are useful. A common camera-mounted strobe like a Vivitar 283(I have a bunch of those) has an ISO 100 guide number of 120. Flash bulb GNs are a bit "funny" and are shutter speed dependent since the light output isn't instantaneous like a Xenon strobe. That's much of the reason why the GN table list different values for different shutter speeds(guide number=aperture(in f-stops times distance)

Very nice looking 17"!Wasn't aware we had so many evil coffee drinkers on the forums. Real men drink tea. Without sugar.

I do enjoy an occasional cup of Earl Gray, albeit with sugar.
And, of course, as a good Southerner, I really prefer my tea cold and sweet all year round.
@weckart My bad the 2Kw metal halide lamp I have is 220000 Lumens
That is excellent. Until you realise with current energy prices that you can only afford to have it on for 10 seconds a day. Either that or slap a frying pan on it and call it an induction cooker.
My G5 positively sips electrickery by comparison.
@bunnspecial Oh very Nice
Sounds about right on the 60W. I stocked up when they quit being available here
So that's what one of those flashbulbs looks like! Somewhere at home I have a Kodak Six-20 Flash Brownie and could never, for the life of me, imagine what kind of flashbulb it must have used.
Thanks for posting that.
Most of the Brownies I've seen used a smaller flash bulb-either a GE #5/ Sylvania P25 or M2 bayonet base for the medium format cameras, or a tiny little AG1 for smaller format cameras.
I grabbed a few out of my "curio cabinet of random crap" to photograph. The first photo is GE #5 next to a Sylvania P25B. These bulbs are more or less interchangeable. Blue bulbs are for use with color film-they bring the color temperature of the bulb up to 5000K or so for daylight equivalence. These are about the size of a Walnut.
The next photo is a GE M2-these are about the size of an acorn.
Finally, the AG1s are about the size of a peanut.
Flashcubes and flash bars generally have 4(in the case of cubes) or 10(with bars) of the AG type bulbs in one enclosure.
I have dabbled in old cameras, and have accumulated a lot of flash bulbs over the years. I tend to buy them when they are cheap-especially if boxed(even if the box isn't full). The ones in my "cabinet of crap" are all full boxes.
And, as another interesting fact-you'll notice that the Sylvania boxes advertise "blue dot" bulbs. Normally, flash bulbs have a 100% oxygen atmosphere to promote fast burning, and also are coated in lacquer both to protect the bulb before firing and to prevent it from exploding during firing. A cracked bulb will not only not work correctly(due to the less than 100% oxygen content now likely present) and is also at significant risk of exploding due to the loss in envelope integrity.
The "blue dot" is a dot of of Cobalt(II) Chloride on the inside of the envelope. CoCl2 is blue in its anhydrous form, but is fairly hygroscopic. In its hexahydrate form, it turns pink. Thus, in a broken bulb, the "blue dot" will usually turn pink.
And there's your chemistry less for today

I drink both
(without sugar, of course)

That's acceptable at least.I drink both
I must confess to having the occasional coffee on a lethargic morning. You drink tea cold?
Thanks! Not my favourite or even my oldest PPC though, I just got it because it was listed as a 'MacBook G4' on eBay which meant I got it real cheap. I needed a new laptop quickly at the time and it seemed to make sense buying one that ran software I knew inside out.
My favourite has to be my iMac G4 which has been with me since 2003. ( Sorry for the mess

Of course!(not Earl Gray though-it's always hot!)

You drink tea cold?
I like cold tea too but usually I drink it hot because it warms me up when it is cold around. In Summer I'd probably drink it cold. What's so surprising about it? Ever heard of iced tea?
Tea is a good alternative to water.
Iced tea is a year-round drink around here.
I can remember once going to a restaurant in Southeast Indiana, just barely across the Ohio state line to the east and Kentucky to the south. I ordered "Sweet Tea", only to be told that they only had "regular" tea but had sugar on the table. I knew then that I was in Hoosier country. As any Southerner knows, this is not an acceptable substitute, as the sugar must be dissolved while the tea is still hot to get the sugar concentrations to acceptable levels.
I understand completely, go to a restaurant in downtown Cincy and you'll get unsweet tea, drive 15 min down into Florence and they'll look at you funny if you order un-sweet.
Growing up in Tennessee, I'm with you here. Only in the last few years have I been able to order pre-made sweet tea at a few restaurants in KS. Most people look at you like you're crazy if you order sweet tea around these parts.
