My PC monitor is directly in front of a white wall. I have this strip glued back of the monitor and plugged the USB cable into the PC. Once I turn on the PC now comes to light. This effect looks great and makes working in Dämmerlich pleasant. The tape is available from 3M, which is why I also think that he will not come off. The light color is ok, not too blue. Price is Top. Would recommend it only.
