Old 2xF40T12 (open)
|
A pair of old 2-lamp F40T12 fixtures. Got then free (they were headed to the dumpster...needless to say they never made it in, saved by a relative before)
The original ballasts were 277v (those are long gone now) so I swapped out for some extra 120v I had laying around.
There is a small metal piece/cover center cover missing in the image...I do have those somewhere too (as well as the fixture covers/doors/diffusers(whatever the real name is)).

What brand/ amp rating are the ballasts in there?
The current ballasts are a GE Bonus Line & an Advance, both .8a (I don't remember what type the originals were)
BonusLine ballast is only rated for 40w lamps, so its probably even older?
Did this originally have 2 single-lamp ballasts judging by the covers?
Looks like it originally had a 2-lamp ballast even with the 2 covers - the 'ballast side' has an extra piece of silver metal mounted inside..
I do have some other pic's of the insides too (& closed up I think) if you want to see them... (looks like I set things up to do a YouTube vid for these, can't remember now if I actually made one)

I do have the Advance ballast too which I can post (as well as a pic with lamps) - can post either of those, but they're not as interesting..
(do have covers/diffusers problem is there's xmas stuff in those because at one point I was using the fixture for that)
