About the etching of Philips 400W tubular metal halide lamps produced in China « on: May 26, 2022, 01:33:27 AM » Author: bulb_tester2009
I found that there was a very noticeable difference between the etching of Philips tubular metal halide lamps produced in China and the etching of tubular metal halide lamps produced by Philips Belgium. And the date code and the detailed date exist at the same time. Does anyone know why?

I've been collecting light bulbs since I was 2 years old, and I've been collecting them ever since.
