Hello Emmi & John. Thanks for the responses.
I was just curious about the 'studio' status, or otherwise, of the Cirrus range. They will most likely be going straight on to my shop site, so I didn't want to go overboard with the description by calling them 'studio' if they're not. I did actually buy them for myself because I thought the colours were bizarre and interesting, but sadly they look quite out of place on my shelves in amongst all the bright and clean-lined Danish glass.
John, do you happen to know if Mr. Annenberg was the designer of the range or, if not, then who that might be?
I'll get some photographs up later today - some new brighter photography bulbs arrived in the post, and I need something to test them out on.
