Clip-on and bookmark-style book lights are small and cheap, which makes the details matter: how wide the beam is, whether there is a warm mode and how long the battery lasts. Five Glocusent options below, using the brand’s own descriptions.
The short version
- Glocusent Pro Max 12 LED Bookmark Reading Light: Slim bookmark-style light.
- Glocusent Horizontal ET-Head Amber Book Light: Wide light bar with an amber mode.
- Glocusent 26 LED Red and Amber Reading Light: Clip light with red and amber modes.
- Glocusent 13 LED Mini Clip-On Book Light: Small clip light.
- Glocusent 72 LED Clip-On Reading Light: Brighter clip lamp for headboards and desks.
Pick by where you read: a slim bookmark light for travel, a wide bar for page coverage, a red or amber mode for late nights, a brighter gooseneck for a headboard.

How to choose

- Battery. Runtime figures are the brand’s and depend on the brightness setting.
FAQ
Are these specs tested by you?
No. We have not tested these lights. The details are the brand’s claims.
What does amber mode do?
Amber is a warm, low-blue color temperature. The brand describes it as gentler for bedtime reading.
How long does the battery last?
The brand gives runtime on the lowest setting. Brighter settings drain faster.
