This is my Philips sgs103, it runs on a 35w Sox lamp, however it should be a 26w Sox-e lamp as the ballast says 26w Sox-e, however it works with a 35w Sox lamp. It runs on a Royce-Thompson Tristar 2000 NEMA photocell and Philips gear.

when opening the bowl up, the Philips 35w Sox lamp immediately comes apparent.

To open the gear tray, there is one screw which needs to be undone. You can now see the Philips gear and the photocell socket.
