This is my Wrtl 2600, it runs 70w SON-T and has a Zodion ss12c mini photocell. The old capacitor is also destroyed by the heat of the lamp, so it had to be disconnected.  The bowl and bowl clips on these often go yellow. The canopy is made from GRP and the bowl is made from polycarbonate.

The industria logo can be seen under the yellowed bowl.

Upon opening the bowl up, you can see the 70w son-t bulb.

Undoing the 2 screws holding the gear tray in place, the gear can be seen.

I had to replace the control gear, as the old gear nearly killed 2 lamps. 1 Edison 70W SON-E and 1 osram vialox 6Y 70w lamp. I replaced it with a Philips dynavision 70w SON ballast. I do prefer magnetic gear, but that magnetic gear had to be replaced, and this is the only 70W gear that I had.

Here is the connections. The earth wire is white as I didn’t have any proper earth wire.
