Glocusent Rotatable Clip on Book Light vs Mighty Bright NuFlex Rechargeable Light
Which should you buy? Our verdict on both, pulled from our full The Best Book Lights: 4 Compared (and One to Skip) comparison.
The Glocusent Rotatable wins on adjustability: a 22-LED dual-row head that turns from 0 to 340 degrees, so it can point straight down for bedtime or lie flat across a large book, with three color temperatures and five brightness levels plus stepless dimming, at a budget price. The Mighty Bright NuFlex is the mid-range rechargeable classic with 35 lumens of 3000K warm white. Vekkia's 1600K amber light is the blue-light answer for pre-sleep reading. Mighty Bright's MiniFlex 3 is a 10-lumen, single-AAA travel light: a different class of product, and not the one for the nightstand.
Glocusent Rotatable Clip on Book Light
Buy itA 22-LED head that rotates 0 to 340 degrees, three color temperatures and five brightness levels with stepless dimming, charged over USB-C.
- Dual-row head of 22 LEDs that rotates from 0 to 340 degrees: point it down for bedtime reading or turn it horizontal for larger books.
- 3 color temperatures (2700K warm, 4200K natural, 6000K cool) and 5 brightness levels, with stepless dimming and stepless color adjustment.

- Glocusent publishes no lumen figure, so brightness cannot be compared on paper with the Mighty Bright lights.
- The maker's page lists no auto-off timer, which some bedtime readers will want.
- The 2700K setting is warm white, not true amber - the Vekkia goes much lower for sleep.

- Mid-range price for a one-head, one-color-temperature light.
