Hello Darell,
My head hurts too, but for another reason (banged into a corner of the trunk of my car this weekend, just escaped the need of a few stitches
)But hey, I'll try and help lighten things up for you.
The E2/E1 beamshaper (hexagonal rubber thing + filter) is a perfect fit for the Maglite AA. And I really mean Perfect. So you can use the opaque or whatever filter you use with the E series on the Maglite as well. Was this done on purpose by Surefire, Dunno. But the diametre of the head only differs by a hair.
So, yes the coloured lens outfit for the Maglite (Plastic hexagonal stuff withe the coloured and one transparent filter) work on the E2/E1 as well. It's a little bit tighter where the lenseholder has to be pushed over the clip screw of the E-series. But after scraping away some plastic, a perfect fit can be obtained.
This is why I use the Maglite lenseholder + transparent lense for the Maglite over the head of my E2. And I can also use the opaque filter of the E2 on my Maglite.
It works!! Can't imagine you guys hadn't found out about that one ages ago.
The question I have is: is there a white transparent Surefire lense to use with the lenseholder? It sounds silly, but I think it protects the lexan lense and the head.
