How bright is it, and can I dim it?

The lamp is a decorative accent light, not a reading lamp. The description lists three color temperatures but no dimming, so brightness is set by the strip itself.

What do the three color modes do?

They change the light's color temperature: warm white around 2700K, soft white around 4000K and daylight white around 5000K. You switch between them with the inline controller on the USB cable.

It runs from USB through the included cable with an integrated controller. You can plug it into a wall adapter, laptop or power bank.

It stands about 32 cm tall and the round base is about 10 cm in diameter, so it fits on a nightstand or a narrow shelf.

Does it need assembly?

It arrives as a single unit with the base and curved light element already formed. You plug in the USB cable and use the controller.
