Track lighting got a bit of a bad reputation in the 1990s but when used properly it is still functional and beautiful especially for the kitchen. Pot lights aimed straight down will add general illumination but not necessarily hit the counter. An angled ceiling light on a track can put task lighting exactly where you need it. Undercabinet lighting can also achieve a similar effect. Combining both will make task lighting in the kitchen look effortless.
Bright idea for unexpected lighting: Look for opportunities to install light fixtures in alcoves tray ceilings and wall niches to trace interesting lines. Notice the hidden lights in the ceiling alcove above the cylindrical fireplace mantel here.
If you enjoy art in your bathroom accent lighting will show it off best. Recessed directional lights provide focused illumination for each piece of art — or in this case for an alcove dedicated to a sculptural bouquet of flowers.
