Happened to me last night, except ... I walked out of my computer room (AKA "The Hell Room") and noticed that the bulb which provides the ONLY illumination to the stairwell between the 2nd floor and the ground floor was no longer doing its job. It had been on for several hours.
So I got another new bulb from the shelf over my water heater, and it didn't work either. I assumed that there was something wrong with the line.
Because it's over the upper landing, it's on a 3-way switch. I assumed that either the switch at the top of the landing (2nd floor) or the switch at the bottom of stairs (ground floor) had failed, so having tested the circuit, I took no other steps. Oh, it's the only direct illumination to the steep stairs.
I didn't notify my landlord at the time, because I didn't want him to hire a contractor to come rewire the house. (NOTE: the place was built in the 1960's for about two dollars, top, and most of the upstairs lights and plug-ins are on one circuit ... the same circuit serves many downstairs kitchen plug-ins. It was a "Lowest Bidder" project; I've learned to have low expectations.)
Tonight, I was thinking ... what are the odds? The original bulb was one of those ECO-FRIENDLY spiral bulbs; the replacement was a conventional tungsten filament bulb. Neither worked; I've done my job, it's now my landlord's problem. Right?
Maybe I haven't explored ALL of the possibilities.
So I took a bulb out of bedside lamp, which had been on all evening, and replaced the bulb in the landing-light fixture.
Ta-DAA! It works just fine. The wiring worked: it's just that two bulbs were burnt out; one of them new, never been used, and of the 'reliable' tungsten filament type. Go figure.
I HAD EXPERIENCED JUST_ANOTHER_GEEK_MOMENT!
A 'long life' bulb failed after six months, and a brand new bulb didn't work at all.
But another not-so-new bulb works just fine.
BTW .. neither the spiral bulb nor the first new tungsten bulb worked in my bedside reading light.
PS: I replaced the bedside lightbulb with another new bulb from the 'new' pack; it works great.
Yes, this is a petty domestic issue.
Now I have to decide how to dispose of that curly-spiral bulb which, if you break it, you need to call for Explosive Ordnance Depot experts, or something.
I put it in the "GLASS" recycle box on the curb. They pick up tomorrow morning.
I hope it gives all those "Do It For The Environment" Weanies a frigging heart attack. I'm not going to EVER buy any of those spiral carbon mercury whatever light bulbs. It's all a lie from The Dark Side!
