I referenced the fenix lampshade above, and really love it. I don't use my Sportsman Extreme very much anymore since I got a couple of these lampshades. They fit on my fenix lights and quarks very well. The problem I have with the Sportsman Extreme is that the low is no where near low enough; where as, my quarks go quite low & are more useful....smaller & lighter too.
I did read what you said, but it did not dawn on me that there was a distinction between the "lampshade" and the "diffuser" until I actually saw a picture. It might have sunk in at a later slower reading, but in any event, it certainly has now.
