Hello, I have a simple question, or what I perceive will be a simple question for you all, and this seemed like the best place to ask and receive accurate information. I was wondering what year the
60w 130v A5 Philips light bulb
was first produced. I cannot find any A5 series information anywhere, the lowest I can find is A15. Anyway the top of the light bulb has China and the Philips logo also if that helps. Thanks!
