Sorry you don't like it.
I can't try mine out because my Kindle hasn't arrived as yet. But I think your photos look good and it is exactly as I expected (and hoped) it would be.
I mean the light looks bright enough (which was one of my worries) and I suspected that yes it would be brighter near the light source but I don't think that concerns me as previously I've used a clip on light which does exactly the same thing. It's pretty hard to get evenly distributed light unless it's coming right directly over the top as in overhead lighting.
