Puck lights cast round pools of accent light and are easy to place individually. Strip, or tape, lights are flexible, low-profile, and give continuous even coverage. Bar, or linear, lights offer bright, uniform task lighting in rigid sections. For all-around kitchen task lighting, bars or strips usually beat pucks, which shine as accents.
The three types at a glance
Under-cabinet lighting comes in three main forms, and each lights a counter differently:
- Puck lights are small, round fixtures that throw a focused circle of light straight down.
- Strip (tape) lights are thin, flexible ribbons of LEDs that run in a continuous line.
- Bar (linear) lights are rigid, elongated fixtures that spread even light across their length.
Puck lights
Puck lights create distinct pools of light spaced along the counter. They are simple to install, often stick-on or single-screw, and let you place light exactly where you want it, such as over a sink or a prep zone.
- Best for: accent lighting, glass-front cabinets, spotlighting specific spots.
- Watch for: visible scalloped hot spots and dark gaps between pucks, since the light is not continuous. They can also glare off glossy countertops if aimed poorly.
Strip (tape) lights
Strip lights are the most flexible option, literally. The thin, bendable ribbon hugs corners and tight spaces, mounts almost invisibly under the cabinet lip, and delivers smooth, even light with no scalloping when you choose a high LED density.
- Best for: continuous, seamless coverage; curved or irregular runs; a hidden, modern look.
- Watch for: lower-density strips can look dotty, output varies by product, and many need a separate power supply and a channel or diffuser for the cleanest result. Cutting and connecting sections takes a little care.
Bar (linear) lights
Bar lights are the workhorse of kitchen task lighting. The rigid housing spreads bright, uniform light and links together end to end to cover a full run controlled by one switch. They mount with screws or adhesive and often include built-in on/off or dimming.
- Best for: strong, even task lighting across long counters; the simplest bright result.
- Watch for: the rigid length must fit your cabinet spans, small gaps can appear at the connectors between bars, and they sit slightly thicker than tape.
Head-to-head
Evenness of light: bars are very even, strips are very even at high density, and pucks are uneven and pooled.
Brightness for task work: bars are highest and most consistent, strips are good and depend on density, and pucks are bright directly below but weak between.
Ease of install: pucks are easiest for a few spots, bars are easy to screw or stick and link, and strips are moderate because of cutting and connectors.
Flexibility of layout: strips are best for curves and tight spots, pucks place anywhere individually, and bars are limited to straight rigid runs.
Visibility of fixture: strips are the most hidden, bars are low profile but visible up close, and pucks are the most noticeable.
Which should you choose?
- Choose bar lights for the most straightforward, bright, even task lighting over standard cabinet runs. This is the safe default for most kitchens.
- Choose strip lights if you want the most seamless, hidden look, need to follow curves, or are lighting open shelving and want the source invisible.
- Choose puck lights for accents, glass cabinets, or spotlighting a single zone rather than lighting the whole counter.
Electrical safety
Plug-in versions of all three types need no wiring. If you hardwire any of them to a switched circuit, turn off power at the breaker, confirm it is dead with a tester, and follow local kitchen-circuit code. Hardwiring, new circuits, or anything you are unsure about is work for a licensed electrician. This comparison is general information, not a substitute for a licensed electrician.
