The problems are general, once the capacitor is a part of the ballasting. With the series LC ballast the dominant impedance is capacitove (it is about 2x higher than the inductive reactance but the inductive get subtracted,when neglecting the magnetic saturation, the 20% frequency increase would cause the overall current increasing about 2.5x; the core saturation reduces the inductance, so the current is then not that high, but still way higher than rated) When e.g. LPS ballast use a resonant generation of the startng voltage, the ballast would operate out of resonance, so does not elevate the voltage as required and the lamp won't start. Or it would be too close to the resonance, so the voltages and currents generated with missing lamp would be so high, the ballast would overheat once the lamp fails to strike. Exact behavior depends on the actual ballast design, so each type needs to be really redesigned when converting to 60Hz (increasing the supply voltage for a series choke technically is a ballast redesign - the easiest one; more complex ballasts would need more complex redesign, involving e.g. capacitor recalculation,...) And why the cap isn't on the schematic? As it is not necessary, once the low power factor is not of any problem (for all series choke ballasts the mains input current is rated without the cap anyway)

60Hz的镇流器用在50Hz的频率上，降低电压使用一点也没事。比如美国制造的118V 60Hz的镇流器在中国用变压器将220V电压降低到110V，频率50Hz保持不变，而且发热也很低。但是日本制造的100V 60Hz用110V 50Hz的电源它发热相当严重。

I tried to translate his comment at Google Translate, and it seems that he is speaking Chinese and that he don't know to speak English.

I lives in Israel, which is a 220-240V, 50hz country.

Have you tried to translate his comment to english before reaching such a conclusion? He say: "60Hz的镇流器用在50Hz的频率上，降低电压使用一点也没事。比如美国制造的118V 60Hz的镇流器在中国用变压器将220V电压降低到110V，频率50Hz保持不变，而且发热也很低。但是日本制造的100V 60Hz用110V 50Hz的电源它发热相当严重。 " Chinese to English Google Translate: "60Hz ballast used in the frequency of 50Hz, reduce the voltage used is also nothing. Such as the United States-made 118V 60Hz ballast in China with a 220V voltage transformer will be reduced to 110V, frequency 50Hz remain unchanged, and the fever is also very low. But the Japanese-made 100V 60Hz with 110V 50Hz power supply it is quite serious heat."

I see his post correctly with Chinese letters in my Firefox (Enconding automatically setted to "Western" in LG), and can Google Translate it to English.

@Ash: Must be a FireFox thing in any other windows programs unknown characters become little boxes. I actually copy/pasted a group of the ?'s from his post so I guess my FireFox really did just convert them... --- I did look at some settings in FireFox (didn't change any) and there's a whole list of languages you can add for it to use.
