Philips SGS204s from the M25

I recently saved 3 philips SGS204s from the M25, they came from junction 10, and they were replaced with holophane V-Max Gen2s. Only a few were replaced, and most of the SGS204s are still there. One is going to another collector, and another one is damaged at the back. The one in the photos is the good one that i think i’m going to keep. Unfortunately, none of them have ballasts, but I think i’m going to be saving more from the M25, and i think they have ballasts.
