Low Pressure Sodium Lamp Control Gear

GEC

For wiring diagrams of the first two ballasts employed on this page, please click here.

Z1616 35 Watt / 55 Watt ignitor-ballast. Click here to watch a video of the lamp in my Simplex Aries 55 Watt SOX lantern being operated by such a ballast.

Z1634X ballast for 135 Watt / 180 Watt SOX lamps.

Z1736 ballast and TCC 18 F capacitor, for 45 Watt - 85 W sodium lamps. Formerly, this control gear ran the lamp fitted in a very rare sodium ESLA lantern on the Market Place, in Chapel-en-le-Frith.

 

Close-up of the leak transformer's label. If the "sodium lamps" mentioned here are the original SO/H type, this will have been made no later than 1955; this being the year that the improved SOI/H lamp was introduced.
