There are also now two different reflector/lens assemblies with different light patterns, same idea as the IQ Cyo R and sport versions apparently.
I've got the 2nd gen E3, so I guess it's 220L. Regardless of the lumen output, it's brighter than my L&M Solo 13W was, and that light was rated at over 350L. The lux rating for the E3 I have is 80 lux, so just a little brighter than the IQ Cyo Sport, at 60 lux.
The two versions of the E3 are different than the two versions of the Cyo. The E3 symmetrical has no cutoff focusing optics, so it's just a plain old round pattern. The E3 asymmetrical has a cutoff optic and supposedly works similar to the Cyo/Edelux/Fly, but in scoping out the pix on Peter White's site, it doesn't do that great a job.
