Thanks for the correction-—I am being very lazy. Are we allowed to produce any of the mercury containing bulbs in the US? Or have the older fluorescent tubes always come from China?
They were common in schools and stores when I was a kid in the 50s. I bet we made all of our own back then. Japanese and Chinese products were pretty much non-existent then and for quite a few years. For a while Japan was a major source of products in the USA and now, of course, Japan has been swamped by China.
