AMPLEX, for me as a German, that's a completely unknown brand.
Did this company produce its own lamps or was it selling third-party products under a private label?

I found this older ad:



Hopefully the Americans here will be able to tell me something about it.

I'm pretty sure I have (or had) some Amplex photo flood lamps. I used to get them confused with Ampex and Amperex, but those are unrelated companies.

I think I saw an ad for them in the appendix of one of the IES reference manuals from that era (50s-60s) but I don't think I've seen a actual picture of one. I initially thought they were the same company as the one that made reel to reel recorders, video recorders, and tapes but it turns out they're Ampex instead of Amplex.

I do believe Amplex was a small American manufacturer of lamps and electronic tubes, which was taken over by Norelco in the 1970s.  For some years afterwards Philips kept the brand alive in countries where it could not sell under the Philips name.  Especially in electronic tubes the brand is very common, and those devices seem to be rebranded versions of standard Philips tubes.  Even in Europe they were common.  At work we have old Tesla Coils made by Philips, and those nearly all contain high power vacuum tubes branded Amplex but still made in Holland.

Im pretty sure these lamps are third party Westinghouse bulbs as the E-H1 was a Westinghouse designation and so were the J-H1 and A-H1, although the latter was also made by GE.

These MV lamp is one of hardest to find for collectors to get ahold of that how rare it is.
