Translucent glass shades on pendant fixtures will reduce glare in the kitchen. Hanging overhead lighting fixtures such as pendants should sit 30 to 36 inches above the island work surface.
Instead of or in addition to sconces hidden lights can add a general glow that bounces off the wall and into the room in an even subtler and more diffuse way. Cove lights are built into niches that hide the light source (often a plain LED strip) but hidden lights can also be obscured by medicine cabinets shelving or storage units.
Adding lights as decorative elements helps set a mood in a space. Provided that general lighting is already installed using lights instead of wall art can be a decorative way to provide ambient lighting.
