One can clearly see what a dim glowing lamp on a HPF rapid start ballast does compared to a lit lamp. Each lamp here is on a single lamp RS Valmont F40 ballast.

F40T12 lamps on Perfekt-Start thermal starter preheat ballasts, also exhibits this behavior at EOL, after they rectifies for a while. This is pretty noticeable with Perfekt-Starts that their thermal starter is wear and can't respond to a rectifying and EOL lamp.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Nice Mainlighter on the right that looks like it has a lot of hours behind it.

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

Yeah, HPF rapid start ballasts also have the tendency to
start up the lamp at EOL, and produce violent orange
flashing on the bad end. Could cause vacuum loss, but
in the most rare cases.

Interests:
1. Motorcycles, cars, Women, and Lighting (especially fluorescent)
2. Weightlifting/staying extremely athletic
3. Severe Thunderstorms of all kinds
4. Food and drinks. So gimme them bbq ribs
Lighting has ALWAYS been a passion of mine. I consider everyone on here to be a friend

I've had a Westinghouse F40 lose vacuum on a HPF rapid start ballast after a bout of violent orange flashing at that end. Also had a Philips/Westy F34 do the same thing.

That Mainlighter will not light on preheat anymore but runs fine on the single lamp HPF rs ballast and the electronic ballasts.

Yeah, I've only seen 3 sylvania lamps with vacuum loss at my
elementary school way back in the day. Some of the vacuum loss
ended up being severe, with absolutely no phosphorus coating
at all on the bad end. These were the first lamps with vacuum
loss I had ever seen as a kid.
