OK, I got my EL400 fixed. The Nashbar is VASTLY brighter. Not too surprising since right off the bat it's 5 LEDs instead of 3.
Here's a side-by-side of the two. Note that I reduced the exposure until I thought the picture reflected my perceived difference between the two lights. Therefore this is ONLY useful as a comparison between these two lights; don't compare directly to other images in my album.
