Can you please tell me how you mounted them? Did you used the angle clips?

Also,can you tell me how close you were able to get to full coverage under your cabinets? It looks like I will have almost 5" of dead space under one cabinet that can be divided at each end.

I mounted the lights using the standard flat clips. No angled clips. I toyed around briefly with the idea of using angle mounts, then decided against it.

I have flat bottomed cabinets. All the bottoms lined up perfectly and there are no rails underneath.

I have ~ 3" - 4"( sum of space from both edges) that the lights do not cover. I don't think it really matters.

The extent of the shadow zones you see depends on geometry.
1. The depth of the undercabinet space. The more vertical depth you have, the greater the shadow zone.
2. Angles. A corner usually is ~ 90 degrees. The temptation is to place the light bar on the hypotheneuse. Doing so would increase the distance to the furthest end of the corner.
3. Horizontal distance from the backsplash.

Fingers crossed!
