Title: Works fine
Review: I bought both this and the Mighty Bright to test them out. Both illuminate both pages of a medium to large size book. The Mighty Bright has a switch to use only one LED which can save on battery life. The brightness seems about the same on both (with the Mighty Bright set on high). The light on the Fulcrum comes out in a narrower range at the top (the shape of the LED beam is slightly triangular) so it might leave the top corners of very large books unlit. Though it costs a little more I prefer the Mighty Bright, the clip is a little less bulky and the option of an external AC power supply (haven't bought one yet) is nice as these do burn through batteries. Still, they are both the only good clip-on book lights I have tried.
