I bought one of these on an Amazon Lighting Pre Black Friday Deal for under $30. It has 5 different hues from 3000k to 6000k = Soft White (3000K), Bright White/Cool White (3500K ? 4000K ? 4500K), and Daylight (5000K ? 6000K). Each has 5 intensity levels = 25 different light levels.
I use it for my portable tying kit. It replaced the folding Ott Lite. It folds flat against itself and so it takes little space in my kit.

It is similar in form to the lamp in the video below but it has 5 hues and not 3 and the LEDs are illuminated across the entire underside of the lamp bar and not just part of the way.
