I have the Mighty Brite also and I find it to be fine for the Kindle2 as far as lighting goes. Even at the single light setting I get quite adequate lighting over the whole page and, with care, I can position it to a non-reflective location.
However, as far as portability, not so good. I purchased the light with the idea that it would allow me to read in dimly lit restaurants and I discovered that; 1) Since I normally carry my Kindle2 in an Amazon Cover without any bag or anything the light is not convenient. Adds quite a bit of weight and flops around unless I hold it correctly while walking about. 2) Once in the restaurant holding the Kindle2 plus light is considerably heavier, think mid-sized hardbound book weight instead of paperback weight.
For reading in bed I've discovered that the light shifts position when I do and requires frequent readjustment which is just annoying.
I suspect that for the DX the Mighty Brite, with its second light, would provide excellent lighting across the entire page.
All in all the Mighty Brite gets a 9 on lighting
, a 4 or 5 on weight
, and a 4 or 5 on convenience
.
