Under-Cabinet Kitchen Lighting: Tape vs. Bars vs. Pucks (and What the Code Says About the Driver)

Stand at your kitchen counter and look down at the cutting board. In most NYC kitchens — a prewar co-op galley, a brownstone parlor floor, a two-family in Midwood — the ceiling fixtures are the only lighting layer there is, and when you're at the counter your own body blocks them. The one surface where you actually need to see ends up the darkest in the room. Under-cabinet lighting is the cheapest fix available in a kitchen. The only real decisions are which hardware, where it goes, and what powers it.

The numbers behind "it feels dim"

Lighting-industry references summarizing the Illuminating Engineering Society's residential recommendations put general kitchen light somewhere in the 20-to-50 foot-candle range and countertop prep surfaces at roughly 50 to 100. Exact numbers vary by source, but the shape is consistent: the work surface wants about double the ambient level. That gap is the whole problem. An overhead layer sized correctly for the room is still short where you chop — before accounting for the shadow you cast standing over it. More ceiling light doesn't close it. A second layer under the cabinets does.

Tape vs. bars vs. pucks

• LED tape — Low voltage (usually 12V or 24V) and the thinnest profile of the three. Because the strip runs the full width of the cabinet, the source is a continuous line instead of a point, which is what softens shadows on the counter. Tradeoffs: it needs a driver and somewhere to hide it, and low-density tape can show individual dots reflected in a glossy backsplash. If dots bother you, compare LEDs-per-meter on the spec sheet before ordering and use a diffuser.
• LED light bars — Widely available in line-voltage 120V versions, many of them cord-and-plug, which makes them the easiest retrofit in an existing kitchen. They're generally brighter per fixture than tape and easier to wipe down. The tradeoff is thickness: under a shallow upper cabinet you may see the fixture body from the seating side.
• Puck lights — Point sources. They throw focused pools and visible scallops on the backsplash, and the farther apart they're spaced, the more spotlit the counter looks. Good for accent — inside glass cabinets, over a short run — and mediocre as primary task light.

Short version: tape for an even, invisible wash; bars for the most light with the least disruption; pucks for accent, not for chopping.

Two placement rules that separate a pro install

1. Mount toward the front of the cabinet, nearest the door, with the LEDs facing straight down. Pushing the strip to the back wall — the instinct most DIY installs follow — lights the backsplash beautifully and leaves the front half of your counter in shadow.
2. If the countertop is glossy, flip the strategy. Polished quartz, granite, and stainless bounce a front-mounted downlight straight into your eyes. On a reflective counter, mount to the inside back of the face frame and aim the light at the backsplash instead. You get soft, indirect light on the work surface and no glare. That single decision is most of the difference between a professional lighting installation and a strip stuck under the cabinet with adhesive.

Where the code gets specific: the driver

New York City adopts the National Electrical Code with local amendments, so these are the article numbers an inspector will cite.

Low-voltage tape falls under NEC Article 411, which covers lighting systems operating at no more than 30 volts AC or 60 volts DC (15 and 30 where wet contact is likely). It requires the system to be listed — either as a complete listed system or assembled from listed parts, power supply included. Just as important, NEC 110.3(B) makes the manufacturer's installation instructions enforceable: if the luminaire names a specific driver or calls for a Class 2 supply, that's mandatory. You don't get to substitute a cheaper driver because it fits the cabinet better.

Class 2 supplies (NEC Article 725, built to UL 1310) are power-limited — no more than 100 volt-amperes and 5 amps — which is why 24-volt tape drivers commonly top out around 96 watts. Article 725 also requires Class 2 conductors to be kept separate from line-voltage conductors unless a listed barrier or a separate raceway is used. In plain terms, nobody should be stapling low-voltage tape leads alongside the Romex feeding your receptacles. Not a code rule but our standing practice: put the driver where it stays reachable. It's the part most likely to fail, and one sealed behind finished cabinetry becomes a demolition job later.

What needs a permit in NYC

The line is whether you're modifying wiring. Plugging a cord-and-plug bar into an existing counter receptacle isn't electrical work. Hardwiring a new switched under-cabinet circuit is — and under the NYC Electrical Code that work has to be performed by a licensed electrician, with the permit filed with the Department of Buildings by a Licensed Master Electrician. There is no homeowner self-permit path for electrical work here.

Worth planning for if you're mid-renovation: the switched circuit, the driver location, and the wire path are far cheaper to handle while walls are open than after. If a kitchen gut is already touching your wiring, that's the moment to run it.
