Makes a difference whether it's elemental Hg or as some compound of it. That should cover "dangerous form".

He has this immortal incandescent bulb > going on ... There's something very like that installed at the old fire station in Livermore, CA. The one bulb in the fixture was installed sometime ca 1901, and it was still working the last time I checked. Yep, still going: http://www.centennialbulb.org/facts.htm

I caught it before it could probably catch on fire. It was quite warm. It was a GE bulb, made in China, UL Listed. I returned a pack of 8 of the same type of GE bulbs. The only fluorescent I have are in the kitchen of my apartment. The 4 foot long ones overhead and a smaller unit above the sink. But they both use a more normal sized ballast instead of the compact ones in CFLs. Greg B. -- Actual e-mail address is gregbuchner and I'm located at gmail.com |
