Thanks Xmaslightguy!
Yeah, it works pretty well though when correctly grounded.
Mike, a clamshell plug is what I call those plastic after market extension cord repair plugs.
So I went back to the transfer station today. I found four good, working (since tested) GE F40 Kitchen & Bath, and a Sylvania F34CW EcoLogic. They all work.
Then I found another goodie. A preheat aquarium light! It's comprised of one 48" lamp and one 18" lamp. It even had a GTE/Sylvania Design 50. The 18" lamp was a GE Kitchen & Bath. So now I have a surplus of 3000K lamps I guess, as if I didn't already have enough, cases' worth of F40WW GEs from the "MainLighter" era.
I'm using it above another cabinet for now as another indirect fixture but will probably end up scrapping it when I move, of course saving the guts. For lamps, I stuck in another Philips F40T12/DX Alto, having a whole case of them and really liking Daylight Deluxe, and for the 18" I stuck in an Eiko 18" daylight lamp I also had a case of.
Worst comes to worst, it all goes back to the dump when I move next. But at least I'm extending some of it's life a little bit! It helps having another Lighting Gallery member around here, when I move I'll probably give them a bunch of transfer-station-save F40s.
There were also cases and cases of slimlines, but they were all GE Ecolux F96T12/CW Watt-Miser, not something I'd want even if they were new, and they definitely weren't. Somebody must have group re-lamped, those and the F40s I saved were in Sylvania CWX cases. See? Lots of slimlines still in use here, being group re-lamped in 2016!
