The companies could repackage the bulbs as 100W HEAT GENERATORS. Suitable for small spaces to prevent frozen pipes, warm baby chicks and other animals.
WARNING! IT IS A VIOLATION OF FEDERAL LAW TO USE THIS HEAT GENERATOR (Formerly known as a light bulb) FOR LIGHTING PURPOSES!
I know you meant that ironically, but something like that really happened a couple of decades ago. The product involved was childrens' sleepwear.
Anybody else remember the federal regulation that demanded that all children had to wear "flame retardant" sleepwear?
This meant parents had no choice but to buy "TRIS" treated clothing, if they wanted their kids to have jammies and nighties. (TRIS was a flame retarding chemical.)
And all-cotton pajamas for children was banned! Too "dangerous"!
To get around this idiotic regulation, a few brave small retailers marketed all-cotton pajamas as "underwear" or "playsuits." They had to put labels on them like yours...
Oh, and the best part was this: TRIS was found to be carcinogenic (just like mercury in those curly lightbulbs is poisonous).
Bingo!
I use 100 w bulbs to keep my pipes from bursting in the wellhouse and in the bathroom (no central heat). They work like a charm, keep the bath pleasant all winter and the well pipes open even in single digits last winter.
I’ve got a stash.
