Not sure if it's just what they're specifying here, but these problem-prone Sun-Techs are also extremely sensitive. There are some in urban areas here that do not turn the light on at night at all because the PC is picking up on stray light from buildings and other lights. This is especially common at gas stations or car dealerships where there's a lot of spill light.
I've seen an increased number of older PCs remain during a lamp change too. They NEVER would leave an old PC at a lamp change unless the spring-loaded ring in a GE fixture broke and the PC socket wouldn't allow the PC to be removed (aka the PCR spins aimlessly around, preventing the PC socket from being twisted and pulled out) but I'm seeing it a lot now. Even on lights with not-so-sensitive PCs. But some still get new PCs. Must depend on the person who does the service.
I ended up removing the cover off the PC and just displaying the guts and using the yellow cover on an older 1988 Fisher Pierce that was missing the window. the original cover was cracked too, so I just broke it off, replaced the CdS eye (which got it functioning again) and snapped the 2011 yellow Sun-Tech cover over the old PC's base. Perfect fit too!
