“Wirecutter's top wearable pick, a two-armed neck light that ran 12 hours straight at full brightness in testing”
Two independent arms light both pages at once, and Glocusent narrows each beam to 90 degrees so the glow stays on the book instead of the bedroom. Wirecutter's testers with fuller chests saw the arms cast a shadow on the page at some angles.

Five brightness steps and three color temperatures, down to an 1800K amber, gave Wirecutter's testers "all of the features we wanted, plus features we didn't even know we should want." Lela Burris saw a bright spot at the top of the page and dimmer text at the bottom, which caused her some eye strain.

Glocusent LED Neck Reading Light
Nothing clips to the book, so it works with any binding or page count. TechGearLab's testers found re-aiming the arms every time they shifted position a bit annoying, and Lela Burris of Organized-ish called it slightly uncomfortable when lying back on a pillow.
Glocusent Bookmark Style Reading Light
It slides onto the back cover "like a paper clip and didn't move at all" (Organized-ish), and SFGate liked that the clear page rest lets you read straight through it. The buttons are touchy, and Wirecutter's testers changed settings by accident while moving the clip.

Wirecutter ran it for 12 hours straight at full brightness, and one staffer took it on six flights and hotel stays before recharging. Glocusent claims up to 80 hours on the lowest setting with one arm on.

After 12 hours at full brightness in Wirecutter's test, its four-dot gauge had only dropped to two, and Wirecutter said its battery lasted significantly longer than similar lights. Long-term owners told Wirecutter they charge it "a handful of times" a year.

TechGearLab named it the most versatile light in its eight-light test: "No other light we tested could outperform the Glocusent in versatility." TODAY's Colleen Sullivan also uses hers on dog walks, at the grill and on an overnight flight.
Glocusent Bookmark Style Reading Light
Built for books and nothing else. SFGate found the head has a narrower range of motion than other clip lights, and one head angled from the top edge can't light a wide hardcover spread as evenly as two arms.

Five of the six sources we weighted recommend it, including Wirecutter, TechGearLab and CNN Underscored's editors. It has close to 159,000 Amazon ratings at 4.7 stars. Wirecutter warns that look-alike clones exist, so buy from Glocusent's own Amazon shop.

Wirecutter's top pick and SFGate's best portable light, with almost 29,000 Amazon ratings at 4.7 stars. Wirecutter looked into one reader's report of a unit catching fire while charging, pointed to its UL certification, and still recommends it.

Strengths & Weaknesses
Glocusent LED Neck Reading Light
+ Strengths
Ran 12 hours straight at full brightness in Wirecutter's battery test, and one staffer went six flights between charges
Two independently switched arms light both pages of any size book without clipping onto it
Narrow 90-degree beams keep a sleeping partner in the dark, and a 3000K yellow setting keeps the light warm
− Weaknesses
Testers with fuller chests found the arms could cast a shadow on the page (Wirecutter)
The arms need re-aiming every time you shift position, which TechGearLab's testers found annoying
At 4.6 ounces it is bulky in a bag and can switch on by accident in transit
Key flaw:The arms need attention.
Glocusent Bookmark Style Reading Light
+ Strengths
Still had half its battery after 12 hours at full brightness in Wirecutter's test, and a four-dot gauge shows what's left
Weighs 1.41 ounces and charges from a USB-A plug built into the body, so there's no cable to lose
Goes as warm as 1800K amber and remembers your last brightness setting
− Weaknesses
Touchy buttons, so Wirecutter's testers changed settings by accident while repositioning the clip
Light falls off toward the bottom of the page, which gave Organized-ish's Lela Burris some eye strain
The built-in plug needs a USB-A port, which many newer laptops and chargers no longer have
Key flaw:The buttons are sensitive, and Wirecutter's testers changed settings by accident while sliding the clip around.

The Glocusent LED Neck Reading Light lasted all 12. Wirecutter named it the best wearable reading light, and one staffer later took it on six flights and hotel stays before it needed a charge.
