I Read 100 Physical Books a Year—and My All-Time Favorite Book Light Is on Sale at Amazon Now

Published on October 27, 2025 03:00PM EDT

As an avid reader (I put down between 80 and 100 books a year), I fall asleep so much easier when I read a physical book before bed instead of scrolling on my phone. I’ve finally found an ally in the never-ending battle against my screen time—the perfect book light. Ever since I discovered the Glocusent clip-on book light, my screen time has been down 40% (from about five hours per day to about two hours). 

The handy, palm-sized device clips directly onto your book and provides the ideal illumination for you to comfortably read without an overhead light on. There are three light modes: amber mode, breeze mode, and precise mode. My favorite is amber mode, which has a warm glow that filters 99% of blue light. It gives you the cozy feeling of reading by candlelight—without the eye strain. 

Each light mode has five brightness levels. On the lowest level, the light is bright enough to see the full page but dim enough not to disrupt other people. This allows me to read in bed while my partner is sleeping without waking them up. The light’s head can also tilt at a few different angles. 

The small size and lightweight build make it so you can clip it to any book, paperbacks included, without dragging the pages down or having the light shift around. I can also attest to the excellent battery life. According to the manufacturer, one charge lasts for 10 to 80 hours depending on the settings you use, and I’ve never had it die on me unexpectedly.

My number-one hack for reading a ton is to always have a book on you, and the Glocusent light makes it so that I can whip out my current read in just about any location or situation. And with a 4.7 average rating based on over 24,000 Amazon ratings, plenty of other people share my experience. 

As one shopper says, “This is a definite buy that is not just for avid readers, but also students pulling late study sessions and even older adults who need a bit more lighting help when reading small print. It’s one of those little gadgets you’ll wonder how you ever lived without.”
