I know of a couple of these but they have fins as well. The rear doors seem to have a goldish color to them. They've also been refitted with PSMH lamps (either 320 or 400).
- Reactors for such high wattage lamps would only be possible on quite high voltages (480V for US and 600V for Canada), but then there would be an isolation problem (the socket shell would have 277V or 347V to ground, which is pretty dangerous).
- I suppose HX ballasts exist or existed for 1000W lamps, but chances are they've been replaced by more efficient and/or safe ballast circuitry (CWA, CWI, regulated lag, etc.)
Apparently GE offered the M-1000 with a 480v reactor ballast. I hope they had some kind of disconnect for the socket, otherwise that 277v socket shell can shock you quite badly (and would be banned in Canada). O_o
I hope there's a disconnect device with that 480V reactor
In Canada any HID lamp running on a phase-to-phase voltage must run on an isolated secondary ballast. I guess it's not that bad on 208V, but 600V would leave 347V to ground on the socket shell, which can easily kill you, especially if you're grounded!
You know, since this does not have a fin on the top, there is a VERY good chance THIS is a remote ballast version according to the Westinghouse catalog from 1965.....
Sadly this and the others are gone, due to the the demolition of the gas plant. It was a facility that liquifies gases like oxygen, nitrogen ect from the air.
