Which gear for 180w SOX?

Except for the obvious proper gear, what gear would run a 180w SOX lamp and how would it be struck without blowing the arse out of the cathodes!?!

I doubt there is one, even if you got a ballast that gives, (close to), the 240 V/0.91 A, that the 180s run at, the shear length of the discharge itself would make it impossible to maintain it to run.
Its a bit like trying to run a 140watt SLI on low loss 90watt SOX gear, take out the ignitor from the circuit and the linear goes out, the ballast itself won`t run the discharge on its own.

Although Thorn made a low loss set of gear for the 135watt, for the 180 I think its autoleak or nothing?

Given that the arc voltage of a 180W SOX is in the region of 260V from memory I think you're going to struggle to drive it from anything other than autoleak gear (unless you've got a 3-phase 415V supply handy anyway!).

Imagine asking around somewhere someone would be able to dig something out. Afraid I've only got one example though which I need for the 180W SOX I have. You'd be welcome to borrow it for a bit though if you're just wanting to try out some lamps you've got.
