Heh. About a year and a half ago, my regular pub rebranded itself with a vintage look to appeal to students and hipsters, and they switched to LED filament bulbs everywhere. I remember thinking, the first time I saw one, that with a little modification, they'd work great as lighting for a magnaguard electrostaff build, or some kind of steampunk lightsaber. Then I researched how they worked, and gave that idea up once I saw the voltage involved.
But holy cow, I'm impressed that someone actually managed to get one to work.
