Skip pricey LED under-cabinet light fixtures if they require running new wiring. Instead, go for LED adhesive tape lights and save up to $500, including labor. Available at home centers, these peel-and-stick flexible LED circuit-board strips come in various levels of brightness and can be cut to length. Best of all, they plug into any outlet, such as one for a wall-mount microwave or an over-the-range vent hood.
From Legrand, this fully customizable under-cabinet lighting system builds off a modular track fitted with outlets (into which LED fixtures are plugged) and USB ports (which charge cellphones or tablet devices).
