Philips Warm Glow. They seem to be obsoleted, all I can find for them is new old stock anymore. Which I've bought up a bunch of, because the damned things keep failing on me. I've had a set of 5 in service for about 6 years, and so far I've had to replace 4 of them for various failures. They're facing down in a hanging lamp with glass globes around them, and I guess that's close enough to "recessed or enclosed" that they fry themselves. I have them in a few places, though I've also purchased... "some" incandescents, before they went out of availability. I should be good for the rest of my life at this point, especially since I run my incandescents dimmed. The wiki article on bulb rerating is informative - as you reduce power, lifespan is "fraction of rated power" to the -12 or -16 - it's some stupidly high exponent, and it's why a lot of people empirically noticed that "bulbs on dimmers never seem to burn out."
