LED under-cabinet lights typically last longer than fluorescent lights and use less energy to reduce operating costs. Their profile is generally slimmer than fluorescent lights, making them easier to conceal under a cabinet or shelf. They run cool to prevent damage to heat-sensitive materials and maintain comfort for people working near the lights. Integrated LED arrays mean there are no light bulbs to install or change. Lights with multiple color temperature settings have a switch for choosing the hue or tone of light to match surrounding fixtures or suit a room or application.
