Here's my question looking for some info. I have a project with temporary power on site 120/208v. I have dual voltage ballasts "smart Ballasts" can I energize them at 120v then once normal power is established feed them with 277v and will they still work??
I was under the impression that once they are fed they are locked into their voltage does anyone know for sure on this?
Thx
