The E1 is the same general size as the e1e. The e1e has improvements like a pryrex lens, a lockout tailcap and the clip was moved from the bezel to the body.

Which means that if you want to upgrade to the KL1 LED bezel, you can still keep the E1e's clip. With the E1 you would have to lose the clip along with the regular bezel.
The last E1's and E2's had the lock out tail cap also. I've got 2 of each with the lock out tail cap. I've put the ExE bezel on one of each and a KL1 on one of each.
