Has anyone determined the wattage point at which a PT400 (double barreled 4C) reflector degrades? I'm beginning to experiment and am curious.

It looks like the top of the screw-on reflector can be cut off above its threaded center that contacts the PR bulb to the switch mechanism. After removing the top, an aluminum reflector might possibly be epoxied on to the reflector sleeve. Hmmmmm.
