Our take on the Ultra-Thin LED Bookmark Reading Light

This is a flat, transparent bookmark with a fold-out LED arm that switches on when you bend it. It gives a warm 4000K white glow from a replaceable CR2032 cell, rated for up to 72 hours of continuous use. At about 0.25 cm thick and 20 g, it slips into a book or a wallet and suits late-night readers, students and travelers. Against clip-on book lights it is thinner and lighter, but it lights a smaller area and runs on button cells rather than USB charging.

Questions and answers

How does the light turn on?
You fold the integrated LED arm over; unfolding it switches the light off. There is no separate button.
How long does the battery last?
The maker rates it at up to 72 hours of continuous use on one CR2032. Real-world life is shorter with frequent switching.
Can the battery be replaced?
Yes. It takes one standard CR2032 button cell, which you swap out when it dims.
Is the light bright enough to read a whole page?
It lights a small area near the top of the page. It suits reading in a dark room but is not a lamp for a wide spread.
Will it fit thick hardcover books?
It is about 0.25 cm thick, so it sits flat in most books. Very tight bindings may grip it more firmly.
What is in the box?
One bookmark light. Check whether a battery is pre-installed before first use.
