Under-Cabinet Lighting: LED Bars, Strips and Pucks

Bar, strip or puck for even counter light

Rigid bars of 10 to 40 inches give the most even light on a work surface, and linkable models daisy-chain so one plug serves a whole run. Flexible strips, sold in lengths from about one to six meters, follow curves and tuck behind a lip but need a power supply that matches their voltage. Pucks make spots of light, which suits display shelves more than food prep. Sit the fixture toward the front edge, behind a small lip, so you see light on the counter and not a glare on glossy tile.

Power source and the safety mark to look for

Hardwired bars are the tidiest and never need charging. Plug-in sets are simplest for renters. Battery models in the listings, some with magnetic mounts and motion sensors, suit cupboards and pantries but dim and need recharging. For mains-voltage products, a safety listing such as cUL indicates that the electrical design was tested. Low-voltage strips need a driver of the same voltage, usually 12 V or 24 V, with spare capacity.

Questions about Under-Cabinet Lighting: LED Bars, Strips and Pucks

What color temperature suits kitchen counters?

3000K warm white feels cozy and flatters wood; 4000K neutral white shows food and cutting boards more crisply. Many sets offer a three-way switch between them, which removes the guesswork.

Can I cut an LED strip to length?

Only at the marked cut points, usually every few LEDs, where the copper pads are. Cutting elsewhere leaves a dead section. Check that the shorter length still sits within the power supply's rating.

Do battery under-cabinet lights last?

They are meant for cupboards and short use. Rechargeable bars with a dimmer or motion sensor last longest, as the light only runs when needed. For daily kitchen work, hardwired or plug-in bars are steadier.
