This High School had about 6 MV Nema Heads around its Perimiter (That i Saw)...most of them have been replaced by the Newer HPS Blasters....this nema in Particular seems like an Easy Fix...but too late now :-(
"Full Size" eh?...reguardless of the size of the housing the size of the Eye's are usually the same.
and about a year ago a 12" Refractor actually fell off one of these...i kept it...if you look at my crude hi/low bay pic thats where that reflector came from....the refractor was mostly intact aside from one crack but that eventually went in the trash in addition to the reflector.
I cant tell for sure but this looks like the same barn light i bough from City Electric Supply. Mine also came with a "real" PC. It had the large 1 inch cadmium sulfide cell. But it was thermal. And the one i bought was flourescent. I only bought the flourescent beacuse flourescents don't take long to reach full brightness and we have it on a switch. That way we don't have to wait 5 minutes for the light to warm up when we go outside at night. I was surprised it is just a self ballasted CFL lamp. No ballast or anything. Just a photocell receptacle, lamp socket, and a CFL.
my porch light has a 13 Watt PL and it takes a very long time to fire up when the temps drop below 50 F i can imagine canada.
though i stuck a 13 watt PL in a floodlight made for a 300 Watt halogen and i could see that one surviving winter because it holds in heat fairly well.
Yeah CFL yardlights aren't practical here in Michigan, I've seen a few they're bright but not so much in the winter! They will often start veryy dim like an HID lamp and take 5 mins to warn up

And at least they used a 12" refractor.

I've actually never seen the ones that use a self ballasted lamp, the ones sold here use a ballast.
