The lighting for this rack follows a similar approach, though without the fancy shade. LEDs are attached to C-channel which is screwed up into the stand frame so it's pretty unobtrusive. I've got a 50-50 mix of warm white and cool white LEDs which are on independent drivers, and I've got my controller set to ramp the warm ones first for an hour or so before the cool one kick in. Makes for a nice sunrise/sunset effect. The lights produce a really nice shimmer that's hard to capture in photos.
