Frosted Incandescent Light Bulb. Purchased in 2011.
We have this lamp, a vintage one (are you surprised) that uses these types of light bulbs. So I think in 2011, but it may have been earlier, when they announced the upcoming ban on these types of lightbulbs I went out and purchased a few packs, because the lamp can’t take the newfangled types of bulbs.
All the other bulbs in our place have been switched over to those swirly energy efficient bulbs, but this lamp must have its way.
Status: Keep of course. In fact, look for clear ones to photograph in order to see the filament.
Kill-ratio: 49:3 or ~16:1
