It lights up my rack units very well. The ability to change colour is really nice, yes cosmetic but it is nice to be able to change the mood of the room/ keep these lights the same as the other lighting in the room.
If you?ve got a floor standing rack that isn?t too tall (mines a 16U one), but sat next to it or stood above I can?t see the 2U?s beneath it, but this can?t be helped, it?s just something to keep in mind.
