COB series LED Strip Light uses chip-on-board technology to create continuous tunable white lighting. The high density of LEDs produces a seamless linear light without the need of a diffused cover. Dotless illumination is ideal for reflective surfaces such as granite countertops, tile floors, and more. The tunable white is also helpful for environments requiring circadian rhythm lighting, such as hospitals and care facilities. Pair with a controller (sold separately) to select from a range from cool to warm white, or changing pattern.
