I'd be hesitant to buy any ballast made in China if they're built like any other piece of crap electronics equipment made in China. The quality control of Chinese made electronics tends to be very low.Yes. It does.
We produce high quality electronic ballasts in China. In the past years we only sell them to Europe, from 2008 we are selling them in USA and Canada.
