I'm guessing this is IS? All the ones I have seen this style in the past have been.

Yes they are, i like it though! The lamp just strikes without any delay at all! What do you reckon to these, Kev?

Compaired to what? Modern HF they are better but compaired to magnetic of their time not as good as they still fail! but they are more reliable than modern Tridonics

Compared to other HFs I supose Razz they sound good then. I have to confess I really like them!

I notice the labelling on this is very similar to the 24v Smart and Brown inverter ballast I now have in my lorry! A good HF'er this one!

Yes, it most probably is a Smart and Brown too, a lot of the Thorn gear was at the time.
