Query: uneven illumination

i purchased this unit because of good reviews. The bad reviews given on the basis of the long charge time and short illumination time, which is for me is not an issue as i use it for still photography and it sufficient time for my needs, and 5 hours charge is not that long, just plug it a forget it, it will be charged.The unit is solid 4 or 5 star unless the one factor that wasn't mentioned by reviewers that i wish it would be mentioned.The real problem that the unit doesn't gives an even illumination. Instead of an even spotlight it gives ring shape of light where light fades in the center and brighter at the ages. This one factor ruined the tool, and its good only as a household flashlight.
