I got a Mighty-Bright 2-Light about 6 months ago, and I just loved it for its bright light.  I'm often a passenger in several-hour-long car trips that go late into the night, and I love having this light to read by (I don't get carsick reading in a car like many people do).  I like the light so much that just a couple of weeks ago, I bought another one as a back-up.  And I'm glad I did.  The LED lights are so nice and bright that my husband and I used these booklights throughout Hurricane Sandy, after our power went out, not just to read by but to use as we moved throughout the house, and also when we took the dog outside after dark.  Both lights were on for hours and never seemed to lose their power.
