In my experience, carlco lenses (purchased from future electronics) kind of work with ssc l2 holders (ordered from led supply). I was using lenses meant for use with luxeon rebels. The lenses fit, but seemed a bit loose. I tend to seal everything up with epoxy, so the loose fit was not a big issue for me.
So why not order holders from carlco? Or do you have a bunch of rebel lenses like I do?
