Isn't there a lens made for the MagicShine bike lights that diffuses the beam in such a way? I recall links to a listing on Ebay somewhere. Let me have a look.
Ok, had a forum search hit here (see the quote). Ebay link here. Apparently fits a C8 pretty well. I might just order myself one for bike headlight use (and to play with).
EDIT - Ordered. Expect to receive by Tuesday! Yay! No long wait from China! Wondering why there isn't more talk about these, esp. by the cyclists.
