I can't think where else to ask this, but I'm looking for a bulb for a lamp in my hallway... I've seen these types of bulbs a hundred times before, years and years ago, but have never seen them since and have no idea what they'd be called.

I'm looking for an old-style 20-40ish watt (I'm guessing) bulb with a clear glass envelope that takes a second or two to warm up to full brightness, and when you turn it off it fades out and you can still see the filament glow for ten seconds afterwards.. It has a very reddish-orangeish glow compared to modern tungsten filament bulbs.

All of the people working hardware stores who I've asked have been oblivious, though they've all been younger than me, and I suspect these bulbs have gone out of fashion because they're likely pretty inefficient.
 





If it had to warm up, maybe a type of HID? Mercury Vapor is bluish, and the only thing redish I can think of, maybe high pressure sodium?

Just sounds like a high pressure sodium lamp to me, but they're not usually used indoors.
 
save the world, go green, buy a cfl. No seriously don't wreck it for others. ;)
 
Those are pretty sweet bulbs... certainly not nearly as efficient as the tungsten (the 60W is equivalent to 15-20W of tungsten bulbs), but it does look cool.

Also, on the topic of carbon lights, look up some videos of a carbon arc lamp... the old style projector light source before they had high intensity bulbs.... pretty cool stuff  8-)
