What to know before buying

The listing describes the light as clip-on and gives a 150° rotating clip, but its specification table lists mounting type as tabletop. Confirm the intended attachment and fit for your setup. Battery runtime and charging time are not stated, so the 650mAh capacity alone does not indicate how long it will run between charges. The listing claims eye-friendly, blue-light-reducing light, but supplies no test evidence for those effects.

Customer feedback is generally positive about functionality, brightness options and rechargeable use. The supplied summary includes a report of the charge lasting after weeks, but this is an individual experience rather than a stated runtime. Opinions on compactness are mixed, which matters if portability is a priority. The listing provides a 650mAh battery and small listed dimensions but no runtime figure.
