This is a good lamp and it is admired by my friends. Couple of things;
1) it runs on a USB connection. This wasn't clear to me
2) it has a battery so you can charge and it will run for about 24 hours if you charge it fully
3) you can change the colour settings and the speed of colour changes
4) this lamp won't work on a timer
If this works for you it's a great lamp.
