OxyLED Under-Cabinet Light Kit, $22 with code CX6GRMG3

OxyLED is best known for its battery-powered light strips, but this discounted kit plugs into an AC outlet, and is designed specifically for under-cabinet installation.

The kit comes with three foot-long LED light bars, plus three connecting cables. You can either plug the bars into each other to create a longer strip, or use the cables to snake around corners and extend your setup. Once it’s all installed, just use the touch-sensitive power button to turn them on and adjust the brightness, and enjoy a well-lit countertop while you prepare dinner.
