Still I struggled. I showed Steven this link to the You Tube video by Jamie Wallen demonstrating how to make a side light. So out to the shop he went to cut and sand the piece of wood. I spray painted it and the next day I installed the 14 inch under-counter light .
It works great.
When I can pry the light off the "extremely strong double stick mounting tape" I will shift its position; not quite on the edge to cut back on the glare.
