A great, very effective way to improve the task lighting in your kitchen, perhaps the most important room in your home, is under cabinet lighting. Just take a look at this recent article from RocketNews:
The primary purpose of kitchen under cabinet lighting is to provide task lighting for countertops, sinks, and stovetops that complements the general lighting in the room. The underside of cabinets provides an absolutely ideal location for task lighting since the light source is close to the tasks being performed but is concealed to avoid direct glare to your eyes. This is one of those perfect lighting situations where you see the light but not the light source. Under cabinet lighting also reduces the shadows created by the wall cabinets and the overhead ceiling lighting. The illumination on the backsplash also can create a bright attractive surface that introduces a bit of accent lighting that enhances the appearance of the entire kitchen. If the under cabinet light is dimmable or has a low light level choice, it can sometimes be used as a very effective night light. In short, good under cabinet light has the potential for adding another “layer of light” to your kitchen lighting scheme that greatly improves the task lighting, enhances the accent lighting, and adds valuable night lighting.
