Review on Hooga Amber Rechargeable Book Light: Blue Light Blocking Clip-On Reading LED for Strain-Free Eyes. Perfect Gift for Students, Kids, Book Worms. by Matthew Coste

I wasn't sure if I should go for the yellow light but I'm convinced. I plan to order a few more as gifts! The light was less than I expected but there is enough light for comfortable reading. It's light enough that I don't notice the extra weight of the book. Using it couldn't be easier - just click on the light to activate it. I usually read my iPad in bed and need some time to fall asleep. I've only seen this light a few nights, but I can already say I fall asleep a lot faster.
