Here is the Philips HGS203 in my collection. It used to be a 250w Philips SGS203, but as the gear was bad, and I had a spare 125w mercury vapour ballast and capacitor, I decided to convert it to 125w MBF!

Here is the gear, the gear came from an Italian lantern, but the lantern unfortunately arrived damaged, so i decided to reuse the gear in a SGS203.

Here is the Edison 125w MBF lamp
