My Collection: 150W SON/MH Gears

This page documents my 150W high-pressure sodium (SON) gears. Due to the cross-compatibility between SON and most MH gears, both will be documented here unless the component specifically states it cannot take one-or-the-other.

This rusty ballast was removed from my Philips SGS306 (Trafficvision). It degraded at the hands of water ingress, and no-longer works. It is a Philips BSN 150L (32?).
