MH on Son ballast

I have an old Thorn 150W SON ballast, and the other day I ran it for a few hours powering an Osram powerball lamp that they state is designed to run on SON gear. I noticed though that the ballast gets quite a bit hotter running this than a SON lamp!

Anyone else noticed this?

Yes, being a smaller arc the Halide will draw a slightly different voltage and current, than the SON.

That makes sense then - I'm imagining an increase in current and decrease in voltage. I just can't believe the difference!
