Interesting with all the options for Voltage on the ballast. You run with 240V still in UK?

Most of our gear in Sweden uses 10uf capacitor for 125W MV. 8uf was in my Swedish Thorn Precincts though, because they must run at 80W MV only. We never have Thorn's gear here, so it might work differently. We have mostly Helvar ballasts here (made in Finland), very good ones!

Its suppose to be a 10! , that was my mistake, but this has been corrected now with a 10!
Yeah we still run with 240 here, (but we calculate stuff using 230 as the number), this was the EU standard that came in a few years back.

The `multi tap` voltages date back to when certain parts of the UK all had slightly different voltages, (this was before the 1950s), until the National Grid was formed, and every thing was standardized.
These ballast was usually made by Atlas, with Thorns name on, sadly this quality gear is now all long gone, although we can still get Philips 125watt MBF ballasts here, for now.....?

Current: UK 230V, 50Hz
Power provider: e.on energy
Street lighting in our town: Philips UniStreet LED
