Under-cabinet lighting is one of the most effective upgrades for any kitchen. It eliminates shadows, enhances task visibility, and adds a modern aesthetic. However, to achieve both functionality and visual comfort, proper installation and light distribution are critical.

First, choose the right fixture type. LED strip lights offer uniform, continuous light and are ideal for linear counters. Puck lights provide concentrated pools of light, while linear bars offer a middle ground. Before installation, measure the underside of your cabinets to determine the required length.

For installation, start by cleaning the cabinet underside thoroughly. Most LED strips come with adhesive backing; press them firmly into place, avoiding bends that could damage circuits. For hardwired puck lights, cut a 1-inch hole for wiring, then secure the fixture with screws or clips. Always connect to a dimmer switch for adjustable brightness—this allows you to reduce glare during evening use.

Light distribution is the key to avoiding harsh shadows or overly bright spots. Install the lights 2 to 3 inches from the front edge of the cabinet, not too far back. This placement ensures light falls on the countertop rather than the backsplash or floor. For multiple fixtures, maintain consistent spacing—typically 12 to 18 inches apart for puck lights, or zero gaps for strips.

The beam angle also matters. Narrow 30-degree beams concentrate light for tasks like chopping, while 120-degree strips flood the entire surface. A common rule: the light should hit your work area at a 45-degree angle to minimize reflections on glossy counters. Finally, test the setup at night: walk around the kitchen to check for dark zones or excessive glare. Properly distributed under-cabinet lighting transforms your kitchen into a safer, more efficient workspace while enhancing its visual depth.
