What the Light affects not really. The 800 lumens of EA is taken almost was not the 520 lumens of LD41 are slightly brighter than the high level of EA4.
Since I have the EA4 in CW I like the more neutral light of the LD41 better.
As for the feel as the LD41 is better for me in the hand.
Both are super lamps but EA4 is not better just because they hat to the turbo you realize not really and charged the batteries unnecessarily.
