My first reading light love is by the same company: mighty bright; and it is the travelflex model.  Actually, if I could combine the light quality of the XtraFlex2 with the design of the travelflex that would be my ideal light. ;) This is hands down the best light quality I have found but the design is a little too bulky and heavy.  I find it to pull on the pages and I find myself adjusting it somewhat regularly as I read. I think this light is best suited for larger, thicker, heavier books.
