Undercabinet lighting spacing
When recessed lighting is ordered by the customer, I generally install one under each upper cabinet. They have a recessed area underneath, so you can't use a fixture quite as wide as the overall width of the upper cabinet. I center the widest fixture that I can under each upper cabinet. In the case of puck lighting, I try to space them out so that the "dots" of light are somewhat evenly spaced out along the entire counter area. Lately, I prefer xenon undercabinet lighting. Keep your eyes peeled for the LED undercabinet lighting that's starting to hit the market. High dollar right now, but really neat stuff.
