I haven't seen the Mighty Bright light myself but I can say that I am quite happy with the cover. The convenience of always having the light available but also of having it be tucked away when I don't want it is exactly what I wanted. The light itself, while not the brightest, is more than sufficient to illuminate the page in the dark - I use it exclusively now when I am reading before bed. It also evens out the reflectiveness in low-light situations. A very satisfied customer here - my only complaint is that it is now just a tiny (so tiny as to be annoyingly frustrating) bit too wide to fit into some of my oversized coat pockets when I want to take it with me.
