So I was working in my lab late one night when i came across an eerie sight (well actually it was like 6pm).... well a occasional flicker, which should have clued me in... but then a smell... so I thought oh great, one of my eBay test equipments must be frying... but then I realize the rigol is the only thing on and it does not smell bad.. the computer smells fine.. hmm, something is making the room light flicker and making something smell bad... maybe something is wrong with the mains and its causing some thing to fry...
the smell gets stronger and stronger... and everything goes dark... duh, the fluorescent light bulb failed. It was still smoking after the light stopped.
I have yet to tear it down but it looks like there was a short on one side of the tube, melting the area where the glass coil was making contact with the plastic housing, and charring it.
I don't know if the light bulb could have potentially ignited, but it is only 8 or so inches away from the ceiling... hopefully it cannot burn with enough force to ignite the insulation behind the ceiling sheetrock. I replaced all of the light bulbs of that brand in my house and now I am going to go on a witch hunt for chinese power supplies and other hazards...
but now I am paranoid. fuck the energy savings if that crap can burn my house down.... I'm keen on replacing all my fluorescent lamps with incandescent lamps... or at least magnetic ballast lamps.. and linear power supplies...
If I feel asleep in a room with that bulb with the lights on I would have undoubtedly received a nice dose of healthy carcinogens...
do they make some kind of fluorescent bulb that has a ceramic, glass, clay, teracotta housing ?I don't see why they can't make the bulbs out of a terra-cotta pot material.. or wall warts/laptop chargers. I would accept the fragility in exchange for safety. Hell, id feel more comfortable with a metal housing then this plastic, at least then it only kills you if you are a drunken idiot (at least for a light bulb).
granted, that plastic should be non flammable, but if their QC for the plastic is as reliable as it is for their driver electronics then I expect the plastic to melt into napalm.
