It's one of those HPF ballasts with low lamp current made for residential use, i don't get why these existed, maybe they can be modded since they're HPF, but i'm not sure.

I don't think these are HPF, they're just in full size cases unlike most NPF ballasts.

I like my lamps thick, my ballasts heavy, and my fixtures tough.

I'm pretty sure it is, since I've seen many HPF ballasts like these, I could also hook it up to a power meter and put a couple of lamps on it and check the PF that way.

Old lighting is, and will always be, the best lighting.

Current seems to suggest HPF, ballast seems to one of those HPF ballasts that are optimized for 34w lamps and drive lamps at a lower current.

I have a Advance from the early 2000s like that.

Actually, you may have a point, I was browsing random photos when I came across this photo of a GE LPF ballast in a HPF housing. Now if we look at the specs of the GE ballast, we see it draws .67 amps and only lists F40T12s on its label. Now if we look at mine, it says .67 amps and only lists F40T12s.

In fact, both ballasts appear to be identical in every way except brand and model.

So I went to test this ballast to see if it is an LPF ballast in a HPF housing, and here is what I found from some quick testing...

Input current (@121VAC), .61A
PF .71

Now I'm not 100% sure about this, but I think a power factor below .9 is considered either normal or low.
I may test it at a later date for more signs it might be a NPF ballast in disguise (like if it will rectify EOL lamps), but i think i may have to do that at a later date.

Well GE did sell their ballast division to Valmont Electric sometime ago. I am still looking for that elusive VEC 4251 (Valmont Electric) or GEH 4251 (General Electric). So the ballasts may very well be the same other then what you said

Out of curiosity, what is the 4251 ballast you speak of?

I believe it's a GE ballast instruction sheet but the odd thing is I have several NOS GE ballasts in their original boxes and none came with that document.

I'm guessing it's GE's equivalent to the "how to change a ballast" instruction sheet that came with a few of my Advance ballasts I bought new at retail.

My bad for not being more clearer it is a document that supposedly has more information about installation and ballast operation. I have been after said document for years after I bought Herman Miller fixture that contains a GE 8G3560 ballast. I know how they are operated and wired but I am just curious to see what that document actually contains.
