Ligman Columbus 2: 35w SDW-T Conversion.
Showing the gear tray with the Philips 35w SDW-T gear mounted.
I've mounted the lampholder so the centre of the arc tube is as the same point as the 70w SON’s.
The CSLS ignitor/stabiliser makes things difficult.
No PFC fitted as I’m not sure what these take and I might not have any that small in stock. Can be added later.

I would have liked to have the ignitor/regulator mounted with the terminals facing down but the geartray wasn't wide enough.
I think Cosmo would be very nice in a bollard!

That’s cool. I really like SDW T lamps they are fast becoming rare sadly. Good work on finding a CSLS controller for 35W they are rare as rocking horse shit. I have a couple of these 35W lamps I have a ballast but no CSLS I wonder what would happen if I used a 50W controller on the proper ballast?
