If you're in need of a new book light — or your bedmate who goes to sleep earlier would prefer you to use one — but you don't want to wear one around your neck, go for a clip-on book light instead.

The 86lux Pocket E1 is actually a bookmark light by design, with an ultra-thin (0.35") and light (60g) body that can mark your place, then unfolds up to 180° to separate the clip and light sections at reading time.

The lamp head itself can swivel left or right up to 90°, and adjusted up or down up to 60°, so there's a lot of flexibility in how you set it up. Plus, not only does it fit all sorts of book sizes, it can also easily be slipped into your pocket.

With a press of the side button, the LED (which is also steplessly dimmable) can be switched between three different color temperatures: amber (3000K), natural (4000K), and cool (5000K), all of which have a soft glow thanks to the frosted light pane pictured below. The 400mAh battery has a max runtime of 80 hours and recharges via USB-C when needed.

Get this highly useful book light for just $15 on Amazon in a variety of colors.
