I got some Philips NOS LPS 35 Watt lamps recently but haven't got enough fittings. Also trying out different ballast set ups. A 36/40 Watt fluro ballast in series with a 70/100 VA inductor / ballast works well. I use a HPS igniter for striking the lamp.
The colours of a Low Pressure Sodium lamp at start up are simply stunning.
