Product Information
Excellent Eye Caring Protection: Gritin LED reading light, with its ingenious 7 high-quality eye-protecting beads at the core, is complemented by a unique honeycomb lampshade design, which subtly softens the light and spreads it evenly, effectively achieving anti-glare, anti-flicker and anti-shadow effects.

3 Color Modes & 5 Brightness Adjustable: Short press the colour temperature adjustment button to switch 3 colour modes: amber light(1800K) / mixed light(3400K) / white light(6000K). Long press the brightness adjustment button to enjoy continuous stepless dimming from 10% to 100%; short press the brightness adjustment button to quickly position the brightness to 10%, 25%, 50%, 75% or 100% of the preset brightness, to accurately match your reading needs, so that every ray of light is just right.

Frequently Asked Questions
Is the light bright enough for late-night studying and paper review?
Yes. The 6000K white mode delivers a crisp, daylight-equivalent beam that is bright enough to read fine print, annotate documents, and review detailed charts without straining your eyes.
Will the 80-hour battery last through a full study week?
Yes. At lower brightness levels, a single charge can last up to 80 hours, which is more than enough for a week of evening study sessions between charges.
Can I use this in a dorm without disturbing my roommate?
Yes. The narrow focused beam keeps light on your textbook or laptop, and the clip keeps your hands free. Your roommate can keep sleeping or studying on their own schedule without being bothered by your light.
Does the stepless dimming help during long focus sessions?
Yes. You can fine-tune brightness in real time as ambient light changes or as your eyes need a break, which helps maintain consistent focus without overstimulation.
Will the memory function save my preferred study setting?
Yes. The memory function recalls the last color temperature and brightness level you used, so the light instantly returns to your optimal study setting every time you turn it on.
Can I angle the light to reduce glare on glossy paper?
Yes. The 90° rotation and 45° downward tilt let you direct the beam precisely, and the honeycomb lampshade diffuses it to reduce reflective glare on magazine pages and laminated study materials.
Is this light good for detail work like crafting, knitting, or model building?
Yes. The focused beam, anti-shadow output, and 5 brightness levels make it well suited for any task that requires precise, shadow-free illumination of small details.
Will it work for late-night work on a laptop or tablet?
Yes. The clip attaches to almost any surface, and the adjustable head lets you position the beam to light your keyboard, notebook, or paper notes without creating screen glare.
Can I use it in a library or shared study space?
Yes. The narrow beam keeps light contained to your own materials, and the USB-C rechargeable design means you do not need to find an outlet or replace batteries mid-session.
Is the 6000K white mode good for reducing drowsiness while studying?
Yes. Cool white light is associated with improved alertness and concentration, which is why the 6000K mode is recommended for active study rather than pre-sleep reading.
How does this compare to a full desk lamp for productivity?
A desk lamp takes up significant space and lights the entire area, which can be distracting. This clip light provides focused task lighting exactly where you need it, leaving the rest of your desk clear for notes, a laptop, and a coffee.
Is it better than a neck reading light for studying?
A neck light shines in your eyes and casts shadows when you look down at a page. A clip light directs the beam onto the page itself, which is far more effective for sustained reading and writing.
Is it more productive than using a phone flashlight?
Yes. A phone flashlight has a wide, harsh beam that drains your battery, requires one hand to hold, and offers no color or brightness control. This light is purpose-built for hands-free, adjustable reading.
What if I forget to charge it before a study session?
A quick 10 to 15 minute USB-C top-up provides several hours of low-brightness use, and the battery indicator on the body shows remaining charge so you can plan ahead.
Can the light help me read on a flight without bothering seatmates?
Yes. The narrow beam is contained to your own book or device, and the cool white mode is bright enough to read at cruising altitude cabin lighting levels.
Will the clip hold up to a thick textbook or binder?
Yes. The clip opens wide and adjusts across 215°, so it can grip everything from a thin paperback to a 2-inch binder without slipping or marking the cover.
How do I charge the book light?
Connect the included USB-C cable to the port on the side of the light and plug the other end into any standard USB power source, such as a phone charger, laptop, or power bank. A full charge takes roughly 2 hours, and the battery indicator will show the charge level.
How do I switch between color temperatures and brightness levels?
Press the power button once to turn the light on, then press and hold to cycle through the 3 color temperatures. Short presses cycle through the 5 preset brightness levels, and a long press on the dimming icon enables stepless dimming from 10% to 100%.
How do I use the memory function?
The memory function is automatic. After using the light for more than 10 seconds in any color and brightness setting, the light will remember it. The next time you turn the light on, it will restore that exact setting.
Will this clip fit on a hardcover book, e-reader, or tablet?
Yes. The adjustable clip opens wide enough to grip most books, e-readers like Kindle and Kobo, and small tablets. The soft contact surface prevents scratching and holds firmly without damaging covers.
Does it work with a laptop screen or computer monitor?
Yes. You can clip the light to the edge of a laptop screen to illuminate your keyboard or notebook. For desktop monitors, you can clip it to a nearby shelf or stand instead.
What is included in the box?
Each package contains one Gritin book light, one USB-C charging cable, and a user manual. The light is ready to use once charged, and no extra accessories are required.
Is the LED light safe to use near children and pets?
Yes. The LED produces no heat, no UV radiation, and no open flame. The surface stays cool to the touch, and there are no small loose parts that pose a choking hazard during normal use.
How long will the LEDs last before they need replacing?
The LEDs are rated for approximately 50,000 hours of use, which equates to over 17 years of nightly 8-hour reading. The light is designed as a long-term companion rather than a disposable accessory.
What is the difference between a clip-on book light and a traditional bedside lamp?
A traditional bedside lamp lights the entire room, can disturb a sleeping partner, and takes up valuable surface space. A clip-on book light focuses illumination directly on your page, keeps your hands free, runs cool, and is portable enough to use anywhere from a bed to a train seat.
