For most cabinets, an LED strip is the better choice. It gives an even, shadow-free wash along a worktop, shelf or wardrobe rail. Puck lights suit a different job: a deliberate pool of light on one spot, such as a coffee station, a display shelf or a glass-fronted cabinet. The right answer depends on what you want the light to do, how long the run is and how much of the fitting you want to see.

This guide compares the two on brightness, coverage, placement, wiring, cost and drawbacks. It also covers how we approach lighting inside bespoke fitted furniture, where the choice matters just as much as it does under kitchen units.

TL;DR

• Choose LED strip for even task lighting along worktops, shelves and wardrobe rails. Choose puck lights for focused accents on a single spot or a glass-door cabinet.
• Neither type is inherently brighter. Strips spread light along the run, while pucks leave dimmer gaps between pools that can cast shadows.
• Fit lights in the front half of the cabinet base, not against the back wall, and test the position before fixing anything permanently.
• Strips are usually cheaper per metre and cheaper to run for the same coverage. Pucks cost less per unit but you need several for a long run.
• Hardwired or mains-connected lighting should be installed by a qualified electrician. Low-voltage plug-in or battery kits are simpler.

What each type actually is

Puck lights are small, round, self-contained fittings. They act like miniature spotlights, each throwing a circular beam. Typical pucks measure 60 to 80mm across. They can be recessed or surface-mounted, and some are battery-operated, plug-in or motion-sensing, which makes them popular as a quick fix where running cable is awkward.

LED strip lights are flexible, linear products with many small emitters along a ribbon-like circuit board. Instead of separate pools of light you get one continuous line. Strips can be cut to length at marked points, so they follow the exact run of a cabinet. Many ranges have adhesive backing, and they work best when set in an aluminium profile with a diffuser. Profiles give continuous lighting and diffusers soften the visible LED dots.

There is also a third option, the linear bar, which is a rigid, pre-built strip in a housing. It behaves like a strip in the room, with a tidier finish and less fiddly fitting. If you are weighing strip against puck, a bar is simply a strip in a box.

Strip vs puck lights at a glance

The style point comes from a UK lighting guide that links strips in profiles with contemporary kitchens and visible pucks with traditional ones. Treat that as a leaning, not a rule. A well-made strip in a recessed channel looks right in a period home too, because you see the light and not the fitting.

Brightness, coverage, shadows and glare

People often ask which type is brighter. The honest answer is that neither is inherently brighter. What differs is how the light is distributed. Strips spread it evenly along the run. Pucks create focused pools, with dimmer gaps between them that can cast shadows.

The numbers help you plan. One UK guide puts task-grade strips at 400 to 1,000 lumens per metre, against 150 to 300 lumens per puck. Measure brightness in lumens, not watts. A US industry guide suggests 300 to 700 lumens per linear foot for task-heavy kitchens, which is a useful cross-check when you compare products.

Here is a worked example. A 1.8m worktop run lit with a 600 lumens-per-metre strip delivers roughly 1,080 lumens spread across the whole length. To match that with pucks at 200 lumens each you would need around five or six, and you would have to space them tightly to stop bright circles with dark gaps showing on the surface. That is why a long counter nearly always looks better with a strip.

Glare and reflections

Glare is the hidden problem with both types. Good lighting should be sufficient for the task, even across the area, adjustable and free from direct glare. The same guide recommends shades or diffusers so you cannot look straight at a bright source.

In practice that means:

• Set strips back from the front edge, behind the door line or a small lip, so you do not see the emitters from a seated position.
• Use a diffuser or opal cover on bare strips to hide the individual dots.
• Be careful with pucks over glossy stone, glass splashbacks or polished wardrobe finishes. A concentrated beam can create bright hotspots on reflective surfaces.

Where to fix them

Placement matters more than product choice. A cheap strip fitted well beats an expensive fitting fixed in the wrong place.

Keep to the front half. For strips, ATOM LED recommends the front half of the cabinet base, roughly 50 to 100mm behind the front edge and behind the door line, because mounting at the rear can leave the working area in shadow. For compact pucks, LoopsDirect suggests about 30 to 50mm back from the cabinet front and says the front half is usually more useful than mounting close to the rear wall.

Test before you commit. The same retailer advises temporary testing. Its view is that the right position depends on where you want the light to land, not on mechanically centring a fitting under each cabinet. Tape a strip or hold a puck in place, switch it on in the evening and look at the worktop, the hob and the chopping area.

Mind the cabinet edges. Position fittings so the cabinet edges do not block the beam, and space pucks to avoid dark gaps. Pucks work best for individual cabinets, shelves and smaller work areas rather than a whole wall of units.

A quick placement routine

1. Mark where you actually work: hob, prep area, kettle, coffee station.
2. Tape a strip or hold a puck at the front-half position and check for shadows from your own body.
3. Adjust until the light lands on the worktop and not on the wall behind it.
4. Only then fix permanently and plan cable routes.

Task lighting, accent lighting and fitted storage

The simplest way to decide is to ask whether the light is for working or for showing.

Task lighting means chopping, reading labels, finding clothes. Here strips win because of their even spread. One UK supplier says strips suit broad worktops, while pucks suit concentrated task lighting or accenting particular areas. Its design perspective is application-led, and we agree.

Accent lighting means a glass-fronted cabinet, a shelf of ceramics or a niche. Pucks are strong here. A cabinet manufacturer’s design guide notes that light strips give smooth, even lighting, while pucks can serve for task or accent lighting in glass-door cabinets. That guide is American, but the principle carries over.

Inside wardrobes and walk-in closets

In fitted wardrobes the logic changes slightly. You want to see colours accurately and read the whole rail without shadows from the clothes themselves. A strip running vertically down the inside of a door frame, or along the underside of a shelf above the rail, gives a continuous wash with no hot spots on fabric. Pucks work well for lighting a shoe display, a jewellery drawer or a feature shelf.

Colour temperature and colour rendering matter here, since a poor choice makes navy look black. Our guide to 3000K vs 4000K lighting, CRI and dimmer compatibility covers that in detail. For wardrobe-specific ideas, see our wardrobe lighting ideas for retrofits and bespoke builds, and for fully built-in schemes, our guides to integrated lighting for fitted furniture and bespoke wardrobe concealed lighting.

If you plan dimming, check that your bulbs or fittings are dimmable and compatible with the dimmer control. Mismatches cause flicker and buzzing, and they are far easier to avoid at the design stage than after the carpentry is finished.

Installation, wiring and safety

The two types install differently. Pucks mount individually with screws or adhesive and connect to a driver or run on batteries. Strips need cutting, profiles, driver connections and cable management. So a battery puck is the quickest to put up, and a profiled strip is the tidiest to live with.

Fitting a strip well

A clean strip installation comes down to a few decisions: where the cuts fall, how the profile is fixed, where the driver lives and how the cable is hidden. If you are choosing profiles or want to soften visible dots, this guide to fitting LED profiles well covers sizing and diffusion in practical terms.

Tips that make the difference:

• Cut only at the marked cut points on the strip.
• Keep the driver accessible, not buried behind fixed panels.
• Plan the cable route before the units go in, or before the wardrobe is fitted.
• Use a diffuser unless the strip is fully hidden from every viewing angle.

What the wiring rules say

Under-cupboard lighting can be fixed to kitchen units under BS 7671, the UK wiring standard, as long as fittings are secured to rigid parts, kept accessible for maintenance and protected from damage such as water or impact. The same page notes that prefabricated, CE-marked low-voltage LED systems with their own drivers and interconnecting cables are typically treated as assemblies of electrical equipment.

In plain terms: a plug-in or battery kit is a sensible DIY job, but anything connected to the mains, such as a hardwired driver or recessed pucks cut into the cabinet, should go to a qualified electrician. Replacing a light fitting with an integrated LED fitting also needs an electrician. Moisture is the practical risk in kitchens, so keep drivers away from sinks and kettles, and never fix lighting to a flimsy panel that flexes.

Cost and running costs

Is it cheaper to use LED strip? Usually, yes, once the run is longer than a single cabinet. Strips are typically the lowest cost per metre, while puck lights cost less per unit but need multiple fittings for long runs, and strips cost less to run for equivalent coverage.

Both are far cheaper to run than the older halogen spots many homes still have. The Energy Saving Trust estimates that swapping halogen spotlights for LEDs saves about £45 a year in Great Britain. It also says LEDs can last up to 25 years, against around two years for halogens. Those figures are for general lighting, so treat them as a guide to the efficiency gap rather than a forecast for a single cabinet.

The bigger cost is labour and finish. A cheap kit with visible wires and a flickering driver costs more in the long run than a decent profile, a diffuser and a proper driver fitted once.

The main drawbacks

What are the downsides of LED lighting in cabinets? The honest list is short.

Strips:

• Bare strips can show visible diode dots, which look cheap on a reflective surface.
• They need more planning: profile, driver, cable route.
• Self-adhesive backing can fail on dusty, greasy or uneven surfaces, so clean and key the surface first.

Pucks:

• They create pools of light with darker areas between them.
• They can cause hotspots on reflective worktops.
• On a long run you end up with a row of visible fittings, which suits some kitchens and not others.

Diffused strips conceal the individual diodes, and an electrician may be helpful for mains-connected strips or recessed pucks. Most of these problems are solved by choosing the right accessory and planning the position early, not by switching product type.

Our view on strip vs puck lights

We build wardrobes, walk-in closets, media walls and storage that sit in real rooms with real awkward corners, and lighting is one of the last things people think about and one of the first things they notice. Our view is simple.

Decide on the lighting before the carpentry is finalised. A recessed channel, a hidden cable route or a driver position are cheap to build in and expensive to retrofit. A strip set into the front of a shelf or door frame looks like part of the furniture. A puck screwed on afterwards looks like an add-on.

Use strips as the default for anything you need to see clearly: hanging rails, shelves, drawers, worktops. Keep pucks for moments, such as a handbag display or a glass-fronted section. And if you cannot decide, test with temporary lights for a few evenings. The room will tell you.

We also think glare is underrated. A beautiful finish ruined by a visible bright dot is a common mistake, so we favour diffusers and light that is aimed at the surface, not the eye.

How to choose in two minutes

Use this short test.

1. Is the run longer than about 60cm? Choose a strip.
2. Do you need to see colours or read labels? Choose a strip with good colour rendering.
3. Do you want to highlight one object or shelf? Choose a puck.
4. Is there glass in the door? A puck, or a strip hidden in the frame, works.
5. Is there no easy cable route? A battery or plug-in kit, either type, is the pragmatic route.
6. Is any part mains-connected? Book an electrician.

Mixing the two is perfectly fine. A strip for the work surface and a puck over a display shelf is a common combination. Just keep the colour temperature consistent across both so the room does not look patchy.

FAQ

Are strip lights better than puck lights under kitchen cabinets?

For most worktops, yes. Strips give a continuous, even wash with fewer shadows, and they are usually cheaper for a long run. Pucks are better where you want a concentrated pool of light on one spot, such as a coffee station or an object under a shelf.

Which gives more light, a strip or a puck?

Neither is inherently brighter. A task-grade strip is typically quoted at 400 to 1,000 lumens per metre, while a puck gives around 150 to 300 lumens each. The difference is that a strip spreads its output evenly, while pucks concentrate it in circles.

Is it cheaper to use LED strip lights?

Usually, once you light more than one cabinet. Strips tend to cost least per metre and use less energy for equivalent coverage than a row of pucks. Pucks are cheaper per unit, so they make sense for a single small area.

Can I fit under-cabinet lights myself?

Yes for plug-in, low-voltage or battery kits, provided you fix them securely and keep drivers accessible. Anything connected to the mains, or any recessed fitting that needs wiring in, should be done by a qualified electrician.

Can I use the same lights inside a wardrobe?

Yes. Strips along door frames or under shelves light a rail evenly, and pucks suit a display shelf or shoe area. Choose a warm to neutral colour temperature with good colour rendering so clothes look true to colour.
