Gritin 16 LED Reading Light book light with 3 modes, stepless dimming and rechargeable battery (Blue)

The essentials

If you read in bed, on the sofa, or alongside someone who likes the lights off, a clip-on book light can make a real difference. The Gritin 16 LED Reading Light is designed for exactly that kind of practical everyday use: a small lamp that clips to a book, ebook, or shelf, with adjustable brightness and colour temperature so you can match the lighting to the moment.

On paper, it ticks several useful boxes at once: 16 LED beads, three lighting modes (Mixed/White/Amber), and stepless dimming (brightness adjustable from 10% to 100%). It’s also rechargeable via USB-C, so you’re not tied to batteries forever.

Modes and brightness control (what you’ll actually use)

Most people don’t just want a light — they want the right light. Here, you get both colour temperature switching and brightness control. A short press cycles through the three modes (Mixed Light, White Light, Amber Light). A long press then lets you fine-tune brightness smoothly from 10% to 100%.

A helpful way to think about it is: colour mode changes the “feel” of the light, while stepless dimming helps you dial it down so it’s comfortable. That matters in shared spaces, a bright white light can be a bit much late at night, while amber often feels gentler for reading before sleep.

Eye-protection claims: good idea, but check your expectations

The product description focuses on eye-protection LED lamp beads and states that the light emits without flicker, shadow, or glare. In real life, the experience will depend on how you position the light and how sensitive you are to glare.

It’s a reasonable claim for this category, but it’s still worth keeping expectations grounded: it won’t replace proper room lighting for everyone, and you may still want to experiment with angle and brightness to avoid “spotlight” effects on glossy pages.

Notably, the lamp is positioned to help you read without disturbing a partner or roommate’s sleep — that’s more about controllability (dimming + positioning) than a magic feature.

Rechargeable battery and runtime: where it sits for daily reading

This reading light includes a built-in 1000mAh battery. The description gives a runtime range: up to 6H continuous use at high brightness, and up to 80H at the lowest brightness.

That’s a big spread, and it’s exactly why stepless dimming matters. If you tend to read quite dim, you’ll likely get toward the longer end. If you read with brightness cranked up, you should expect the shorter end. There are also 4 LED indicators to show current battery status, which helps you avoid the “it died mid-chapter” moment.

Charging is said to take about 2 hours when using the included Type-C cable.

Clip, neck and portability (the day-to-day comfort test)

The lamp uses a flexible 360° gooseneck made of silicone tube, so you can bend it to line up the light where you want it. There’s also a sturdy clip with non-slip silicone pads between the clip surfaces, aimed at preventing marks or scratches and keeping it stable.

In practice, you’re trying to solve two things at once: keeping the light from falling off, and directing the beam consistently as your hands move. The ability to rotate the neck through 360° helps with both.

It’s also small enough to carry and store easily — the description suggests you can store it in a backpack without taking up much space, which makes it a sensible pick for commuting, holidays, or reading in different rooms.

What to check before you buy

There are a couple of things to be mindful of based on the information provided.

First, runtime depends heavily on brightness. If you expect to read at high brightness for long sessions, the stated “up to” times will feel closer to the low end.

Second, it’s a clip-on light. That means it’s ideal when you have somewhere to clip it (book, ebook, shelf) — less so if you mostly read on devices or in setups where clipping isn’t practical.

If you’re very glare-sensitive, also consider that angle matters. A small lamp can become harsh if it’s too close or aimed directly into your line of sight.

Who it’s for (and who may want to skip it)

It makes sense if you want a rechargeable clip-on reading lamp with both mode switching and smooth stepless dimming. The three colour temperatures (Mixed/White/Amber) are a nice touch for changing environments, and the 4-level power indicator helps you plan charging.

It might not be a great match if you need a high-power room-style light for long reading sessions, or if you don’t like the idea of clipping a lamp to your book or device. It’s more of an assistive, targeted reading light than a replacement for a proper desk or bedside lamp.

Final verdict

Final verdict

Worth considering if you want a practical book light for bedtime and shared spaces, with stepless dimming from 10% to 100% and three colour modes, plus USB-C charging and a clip that’s designed to stay put. It looks well set up for everyday reading where you’ll adjust brightness often.

Skip it if you know you’ll always use high brightness for extended periods, or if you prefer a light that doesn’t involve clipping/positioning each time you read.
