Of course you know that there are disc type NTCs that fit in the bottom of
a screw-in E27 bulb (and others), and that they are sold in bulk (12 or 24
pieces per set) for something like $20 or less last time I looked. Just
don't use these in plastic fixtures (the heat has to go somewhere - even
if it's 5W).
