I was hoping I can use a german electronic ballast for T5s, because they have models that can power four T5s at a time plus being dimmable, I think it is a wonderful product that is overlooked in the US. I am presuming i would need a transformer to wind it down to 120v. Where do I search for this? Next question would be ,I am wondering I recall transformers at 240 volts were more common in the US market some time ago, wondering if anyone can tell me what and why it is phasing out, besides the fact that you need another component which is the transformer. I would appreciate some tips from the pros out there.
