So we could use a Thermistor, PTC, not NTC, for this exact purpose, with a volt meter or Zener and LED across it to show when the voltage drop exceeds a certain voltage? I'm sure the specs would need to fit certain requirements, but seems possible at first glance.

So when Kmart moves on to the newer bulbs, old stock is sold off to places like that. Just like NOS tubes.DON'T FEED THE TROLLS!

Or how about a 120V/100W heating element? If it's burning the crap out of you, you may have a short"Take two placebos, works twice as well." Enzo

Just wrap a slice of bacon around it, so now you have a Nose-O-Meter checking shorts.
Shorting the amp on purpose to collect the prize is considered cheating
No, seriously, problem with any kind of heaters is that they have way too much mass and take long to get red hot.
Besides they will never ever work at such a high temperature as a Tungsten lamp filament (2700K), some 4400 Fahrenheit
And lightbulbīs minimal mass makes it VERY fast.
Where did I pick the 2700K number from?
Why, itīs right there, printed on the lamp itself (or its cardbard box).

The decorator bulbs are still available too. They come in sizes up to 60w (I believe that's all the higher they go) and you can still get something like 60 watt FLOD lights that are incandescent. I've got a boatload of the regular ones so I'm stocked up for this century. Mike.
