Life is stranger than fiction at times. It appears a simple thermal protection device made by Leviton (http://www.leviton.com/pdfs/m2000/M-2000e.pdf) as an OEM for Lightolier is next to impossible to buy. Even the few electrical supply houses I called don't carry thermal protection devices. And electrical contractors cannibalize old recessed lights for them. Now I can't believe it's so hard to buy a very simple and important safety device except in lots of 500. Anyone know of a cross to a Leviton 9454A10 (7.2K resistor, 110 degree C temp, 120 volts) thermal protector, or as Leviton calls them, "Self-heating Thermal Protectors"? Thanks again for all your help.
