Sylvania HF100 fixtures

Sylvania HF100 fixtures

I recently picked up 7 of these HF100 fixtures. They are not preheat, but appear to be original rapid start. The one I opened has a vintage Jefferson ballast in it.

Nice finds!

Good quality things are awesome. Cheaply made things are not.

Nice lights. I'm sorry to say but I think these were originally preheat converted to rapid start.

Who ever did it did a pretty neat job but you can see snap in covers installed where the starter sockets would have been as compared to a unpunched factory knockout. You can see the covered starter socket hole vs the unpunched starter socket knockout on the left set of starter knockouts.

I wonder if who ever converted them to rapid start used a kit since the wiring looks pretty neat without any splices at the lampholders.

Nice haul! Even RS those are a great find!

The covers look like the kind you can buy to plug knockouts.

I think they were originally rapid start as one of the covers says right on it, 'Use rapid start lamps only', and there are no marks where the starter sockets would have been.

It is possible the starter socket holes came punched from the start of the assembly line because almost all lights from that era were preheat. So for the few RS fixtures they made perhaps they used knockout seals?

Yeah could be possible RS was so new at the time that it had to be requested when placing an order or else preheat was default

Interesting. I commented on some earlier pix I was sure these had to be a later conversion, but that stamped in the reflector seals the deal. I thought that came later, though- I have some '70s era fixtures with that stamped in the reflector.

Yeah I always though the "USE RAPID START LAMPS ONLY" stamp was later, like 60s or 70s fixtures. I think the irony is that by then most manufacturers stopped making preheat only and rapid start only models of F40 lamps and made a single preheat and rapid start model instead.

I have some '90s Sylvania F40/DSGN50 that still say "Rapid Start".
