Hmm, Dayton is a fan manufacturer.

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

I thought odd too...What is their name doing on a Philips lamp? Perhaps a marketing experiment...or a lamp size that fits something associated with one of their other products?

I had a couple of these back in the day. I should have kept them. It is funny that Dayton had their name on fluorescent lamps.

Nice find, thought Dayton only made motors and fans.

Long live the great old 20th century quality in electrical & lighting products!

They were an electrical supply distributor sourcing products from various sources and putting their name on it.

Preheat and T-12 fluorescents forever! Down with LED's and instant start T-8 fluorescents.

Somewhere in my pile(s) I have some rapid start Dayton Ballasts for 2 F40 lamps. They were in some preheat fixtures that I bought and converted back to preheat.

I don't really understand the "Preheat-rapid start" thing. Is there a true difference electrically in the cathodes between a preheat, preheat-rapid start, and rapid-start lamp? I know many 34 watt energy savers were marked as rapid start to prevent them from being used on the older "TuLamp" preheat ballasts and causing nice, smelly, tarry, PCB-leeched meltdowns (and possibly even starting fires) but still...

I don't either I believe there about the same but definitely not f34s they belong in those 4 lamp troffers in drop ceilings or heated large buildings with tons of lights

A "preheat" lamp has 9v cathodes; a "rapid start" or "preheat-rapid start" has 4.5v cathodes. The rapid start ones work fine on preheat, of course, but the preheat ones will wear faster if run on rapid start. Most lamps are either distinctly preheat (F15T8, F20T12) or rapid start (F30T12, F32T8) but I can name two that began as preheat and changed to rapid start in the 50s: the F40T12 and FC12T9.

FYI, "trigger start" is just a term for a rapid start ballast for use with preheat lamps (higher cathode voltage).

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

Cool thanks for the info. But how about preheat/ rapid start in combination are those 9v cathodes?
