This one starts the lamps without a grounded reflector and also has a nice long pronounced startup flicker.

I wonder if this would work with European F18T8 (Basically the T8 version of US F20T12 tube) fluorescent tubes? I have read somewhere that rapid start can not start To fluorescent tubes, only T12 because something about natural cathode emissions being much more eased in T12 tubes, rather than needing to be forced in T8 tubes??? Is it true?

New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.
We shall reinforce ourselves with good old full mercury t12s and HIDs made to surpass one's life, and give them all the middle finger ;

@vytautas_lamps: It won't work with the European 18W T8, and I think also with the European PL-L 18W, as these lamps uses krypton gas, which have much higher starting voltage than argon, and the American Rapid-Start don't produces any HV during ignition, and uses a constant current cathode heating transformer winding. Also, Rapid-Start ballasts have the lowest OCV than any other ballast topology (An average OCV for F40T12 ballast is 180-200V, and krypton lamps like the European T8 and PL-Ls, requires 240V to maintain their discharge, so resulting in the lamp extinguishing even after the discharge has been struck successfully).

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

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

I don't think it's true. Magnetic rapid start ballasts for F32T8 lamps were made here in America.

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.

F32T8 (Which is an American format, which isn't sold worldwide) is argon, so it have much lower starting and restriking voltage than the European 18W, 36W and 58W T8, which are all krypton. Krypton fluorescent lamps won't start and work reliably on rapid-start.

Do European T12s have argon or krypton gas? If they have argon gas, they might work on US magnetic rapid start ballasts.

The average OCV for F40T12 ballasts is 220-280v depending on ballast type. Anything less than 210v wont start the lamp reliably, especially rapid start. The magnetic F32T8 ballast have OCV ranging from 250v to 350v

European T12s are the same as American T12s and will work with no problem on US rapid-start ballasts.

But then why are the European T8s different?

The Europeans developed the T8 lamps as a direct retrofit for T12 on their existing series chokes. As these lamp uses krypton to increase their efficiency, their starting and restriking voltage is higher than the argon T12, so they can't be operated on the American gear for T12 lamps, which is mostly rapid-start, which don't uses HV for starting, and have too much low OCV to get these lamp stable operating, so the Americans produced dedicated T8 lamps with argon designed for dedicated rapid-start ballast (Similar to the European T5 lamps which are designed for dedicated electronic ballasts).
Read here for more information.

Would European T8 lamps work on American T12 preheat ballasts?

Yes, but only if the ballast OCV is >220V.

While differences between US and EU T8 tubes are known, shouldn't T5 tubes and PL-L tubes be the same in US and EU? Overall basic T12 tubes are mostly the same (most countries in Europe never had any contact with HO and VHO tubes, those few that had contact imported lamps from the USA), there only some exclusive formats like 14W for the USA and 1m 25W for Europe. As for T8 tubes that are the same in both regions, I think 15W and 30W are the only examples. What is interesting is that 30W T8 are exceptionally abundant in bus interior lighting in Europe.

I think that all of the long T5 lamps are the same in the US and EU (14W, 21W, 28W, 35W, 24W, 39W, 49W, 54W and 80W, rated for electronic ballasts both in the US and EU). But PL-L isn't, since the EU PL-L are rated for electronic ballasts and emergency modules only, while the US PL-L are rated for rapid-start.

I have a couple of the 36w, and they fired up just fine on a F40 preheat ballast
And the 18w have no problem on a F20 preheat (will also work on some RS ballasts)


------------
It'd be interesting to see if this ballast would fire up a single F28T5 or F21T5..

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

To be precise, 18W and 36W EU PL-L can also be found in preheat circuits with bimetallic starters, 55W are electronic only.

What rapid start ballasts other than designated ones like this one can run 18W PL-L lamps? And I don't have (and probably won't get) any modern T5 lamps designed for programmed start ballasts.
