Don't settle for poor lighting. The kitchen is one room where you can’t afford to have poor lighting. It’s not only a matter of design and atmosphere, but also a safety matter when it comes to handling sharp kitchenware. Rooms generally need three types of lighting: general lighting for overall illumination, task lighting and accent lighting. For the kitchen, you especially should evaluate the work areas and focus on how you can provide each spot with the light it needs. Consider adding lighting directly above all the main working areas, perhaps using pendant lights or a series of mini-pendants in areas where these enhance the lighting and beauty of the kitchen. Pendants look great above kitchen sinks, while a series of mini-pendants enhance the appearance and lighting of breakfast bars and kitchen islands. Also, install under-cabinet lighting as an additional way to ensure that the counters have sufficient lighting for common kitchen tasks. After all, the more light you have in the room, the better you can show off all of those amazing design elements you’ve added to the space.
