If you are looking in to the light yes, old version is brighter, because it have only a big hot spot without spill.
Make a test in a room in total darkness with the lights on the ceiling, eyes on the floor.
There are no differences in overall light power between 2014 edition (middle level) and the old version.
It is clear if you look direct in to the light, the old version have a brighter (and bigger) hot spot, but new version have a nice defined hot spot (not so bright like on old version) and lot of spill which is absent in old version, but overall brightness are the same (can not see a difference without a luxmeter) .
Both of my E05 have a nice neutral-warm light, identical in color, no greenish or blueish, just nice neutral-warm color.
I like the old version with diffuser (good light on a big close area) , I like new version because of the nice defined hot spot and spill (a lot of spill) and for the 3 levels.
Last level is pretty bright for this size.
Unfortunately to the new version the lens is prone to scratching, old version with diffuser is a lot more resistant.
