Whats the set up with these then?, do they have a heavier cathode set up in them?

I really have no idea how they differ from a 'normal' one.

That a Odd ball, and being 3500 k white too! Cool

Would they have thinner cathodes that heat up faster?

@oliver: That is possible, but I do not know for sure. Maybe its also possible they could have thicker cathodes that maybe deal with the abuse of cold-starts better?
