Is the Cyezcor light bright enough for video calls?

At 10W it is meant for close fill on a face at desk distance, not room lighting. It works best in a dim room where it adds soft, even light without glare.

Can I change the color temperature?

Yes. It adjusts from 3200K warm light to 6800K cool daylight, with a dimmer, both controlled from the in-line control on the cable.

What can I plug it into?

Any USB port or USB charger: a laptop, monitor, phone charger or power bank. There is no built-in battery, so it needs a USB source to run.

Will the clip fit my monitor?

It is a clip-on monitor mount, so it fits typical flat monitors. Very thin or curved panels may grip less securely, and it is not designed for phones or tripods.

Is $11.99 a good price?

It is the best new price among the three stores listing it, at eBay as of November 7, 2026. That is a low entry price for an adjustable ring light, so it is a reasonable buy if the small size suits you.
