This Mighty Bright Xtraflex 2 has 2 LED lights and a 3-way switch that cycles between off, one LED on, and two LEDs on. The press-switch seems well made. The design is stylish. I also have an original Mighty bright that had one LED and a shorter base, which was less stable than the new model and a sliding switch (not as handy as a press switch).  I also have a very similar light made by Fulcrum (Multi-flex), which has only one LED, looks cheap, and has a sliding switch that feels prone to breakage. Any of these will get you through many long winter evenings on one charge using three rechargeable AAA batteries. All of these LED lights with a standing base are too large and heavy to use clipped to a paper-back book, in my opinion. However, they clip very nicely in a man's shirt pocket with the LED under your chin shining on the book while you sit in a reading chair, although my wife says it makes me look like a cyborg.
