Immediate Failure
Initially I was thrilled to find this book light.  I have a desk top Verilux Natural Spectrum light and have been pleased with the natural spectrum light and it's performance.  I was completely underwhelmed with the Verilux travel light.  When I turned it on for the first time the high beam light was clear and bright.  It completely illuminated the page.  As I settled in to read, the light flickered.  Within minutes it was flickering nonstop.  Then the high beam setting completely failed.  I was left with a subpar low beam light.  This light was not sufficient to completely illuminate the page so I was forced to make adjustments to read the lower half of the page.  I do not recommend this book light.
