Glocusent Reading Light,Bendable Neck Light,80-hr Rechargeable Book Light

The Glocusent neck light hangs around your neck with two bendable arms that point down at whatever you're holding. It costs about $20 and has a 4.7-star average from roughly 159,000 reviews, which makes it one of the most-reviewed reading lights on Amazon.

What you get

There are three color temperatures: 3000K, 4000K and 6000K. Each arm has its own switch with three brightness levels, so you can run one arm on low for reading in bed. Glocusent says the beam is a narrow 90 degrees, which keeps the light on your book rather than spreading toward a sleeping partner.

It charges by USB-C. The 1000mAh battery is rated at up to 80 hours with one arm on low, or 8 to 10 hours with both arms on high. Glocusent offers a 60-day return window and a 24-month warranty.

The warmest setting is 3000K. That's warm white, not amber, so if you want the lowest-blue option for late at night, a light with a true amber mode is a better match.

Who it's for

• Reading thick hardbacks or e-readers in cases that are awkward to clip onto
• Knitting, crochet and other hands-on hobbies in the evening
• Anyone who wants the light to follow the book as they shift around

Who should skip it

Some people never get comfortable with something around their neck in bed. If that's you, a clip-on like the Glocusent clip-on is simpler and has an 1800K amber mode.

Alternatives

The Gritin 9 LED is a cheap clip-on (about $10) with stepless dimming. The hooga amber book light is 1600K amber only. See all four in our best book light for reading in bed guide.
