Here is an article from MSN/The Washington Post about Designers are hoarding incandescent lightbulbs before they disappear.

Never thought this would end up on the news. We need to fight for these lamps!

Reminds of of this article that showed up around this time last year. Interestingly one of the lamps shown is a BT-37 coated 400w MV or MH lamp.

Hoarding them for daily use is a bit pointless since the because you often replace a lamp in regular use every year, the hoard will run out in like 10 years or so.

I would "hoard" them for historical reasons and incidental use, not use in completely new lighting designs...

We have dim to warm LEDs here in the living room, they're pretty nice. The only thing i loathe is that they're integrated lamp+armature systems so if the driver pops in like 10 years time, i gotta throw away a perfectly good LED board unless i make my own driver for it.

Somehow I’m not that concerned about the disappearance of incandescent lamps, especially since I’d rather just use LEDs due to the energy savings. And retrofitting then into most situations is as simple as replacing the bulb.

But I am more concerned about not being able to get HID and fluorescent lamps. LEDs can’t replicate the color or behavior of HID.

I'll buy vintage incandescent lamps if they're unique, and/or rare...otherwise it's been  LED filament bulbs for daily use simply because they're readily available and cheap to buy and use. LED doesn't do a good job replacing HID, and they don't have personality like discharge lighting.
Why do you think I've stocked up on HID lamps?

I have some incandescent lamps, but I don't use a lot of them since they are pretty power hungry. I have a couple of traffic signals with incandescents but that's because nothing really comes close to the beam pattern of a incandescent in a traffic signal and the same applies for the slight fade out incandescents have when the lights change.

I'm more annoyed at the push to discontinue fluorescent and HID, as others have said. At least those when used for long switching cycles last significantly longer than incandescent so you don't need to hoard a lot. A case of HID lamps is pretty much a lifetime supply for a fixture, same goes for a case of fluorescent.

Same here, I like the led filament bulbs, and they at last look like classic light bulbs. I usually buy them on clearance or at Ollie’s since they’re way cheaper.

I’m pretty stocked up on 175 MV bulbs, mostly ones I’ve also gotten on clearance, and since they last a long time anyway. I would like to get more HPS bulbs, I don’t see a wide variety of wattages on clearance often.

I use them in every occasion that isn’t HID, mainly due to the fact that LED bulbs hurt my eyes and I don’t use that many anyway.
