The light output looks very similar to me, but the information I have seen gives a lower output rating to the Edelux II and Peter J. White's website used to say it was the same as a cyo premium. His website is a bit of a jumble, so I didn't find it.

Who am I to believe, the internet or my lying eyes?

Manufacturers often upgrade lights as better emitters become available. I have wondered if they did this with the Edelux II. It was released over 6 years ago.
