Japanese 100V CFLs « on: May 14, 2022, 11:44:17 AM » Author: Patrick
Do any of you know how 100V 50/60Hz electronic self-ballasted CFLs from Japan would perform on 120V 60Hz?  Would a 100V transformer/converter be needed to avoid burning out the ballast?

Electronic CFLs can works on both 50-60hz, but can't work on wide range of mains voltage like programmed start electronic ballasts, so I think the ballast may be overdriven.

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

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

For safety’s sake, I would recommend using the lamp on a variac set to 100v since the electronic ballasts do not mind the frequency as much as magnetic ballasts use. I do have some Japanese 100v 50hz/60hz electronic ballasts intended for 2 FPL36 CFL lamps that I have not energized yet because I do not want to risk destroying them on 120v mains.

U can take any control transformer from a Junk A/c unit as most are  120 to 24 volts.  Most around 40 VA that is perfect for japan CFLs   All you got do is wire them as buck transformer drop it down to 96   Volts.   Unless u have a older outdated electric service from the 1920s  it might put out 110 volt.  But some electronic CFLs  can take higher voltage but it can be risky .  If not I have hundreds of those 120 to 24volt transformer.

No LED gadgets, spins too slowly.  Gotta  love preheat and MV. let the lights keep my meter spinning.

I have an electronic ballast fluorescent bulb from NEC (nominal 15W 100V 50/60Hz) and I use the 220V to 110V transformer I bought to run it. The measured power is 16W, and there is almost no overcurrent.
