A kitchen in two layers: a continuous line of light under the wall cabinets above the worktop, pendants over the island, and a few spots in front of the cabinets (AI-generated illustration)

Kitchen lighting: The complete guide

A kitchen is a workspace before it is a showpiece. The best-known mistake is a ceiling full of spotlights behind you, so your own shadow falls on the chopping surface. The solution is task lighting directly above the worktops.

The most common mistake: your shadow on the worktop

The complaint we hear most often: “The kitchen is dark even though the ceiling is full of spotlights.” The reason is that spotlights in the middle of the ceiling sit behind the person standing at the counter, so their body blocks the light and casts a shadow exactly on the chopping surface. Upper cabinets add more shadow over the back of the worktop.

The solution is a separate task-lighting layer: a strip or line of light under the upper cabinets, close to the front edge, lighting the worktop directly in front of your hands.

The layers of a kitchen

Layer	Example	Purpose
Task lighting	A line under the upper cabinets, or focused spotlights over the island	Chopping, cooking and reading
General lighting	Spotlights in a line in front of the cabinets, or linear lighting	Movement and cleaning
Island lighting	Pendants or a suspended linear light	Defining the island and the seating around it
Display lighting	Inside glass-fronted cabinets or on open shelves	Beauty and depth
Concealed lighting	Under the base cabinets or above the upper ones	Visual lightness and night-time light

Under-cabinet lighting done right

Place the line near the front edge of the cabinet, not near the wall, so it lights the whole worktop and its source cannot be seen when standing.
Use an aluminium profile with an opal diffuser, or a continuous COB strip; on glossy marble and quartz, an ordinary strip's LEDs reflect as an annoying row of dots.
Avoid surface mounting without a profile: heat shortens the strip's life, and steam and grease stick to it.
Plan the Driver location and the power feed to the line before the cabinets and tiles go in; this is the most frequently forgotten point at first-fix stage.
Put the task lighting on its own switch, preferably dimmable.

The island and pendants

Hang pendants so their lowest point is roughly 75 – 85 cm above the island surface, so they do not block the view between people standing.
Their number and spacing follow the island's length: two or three equally spaced pendants, or a single suspended linear light.
A clear glass pendant dazzles the eye if the lamp is visible; choose a diffuser or a matte lamp.
If the island is a main work surface, pendants alone are not enough; add focused spotlights or choose pendants with strong downward light.

Colour temperature and colour accuracy

A kitchen needs to show food, meat and vegetables accurately, so CRI 90 or higher is not a luxury here. Colour temperature should be 3000K – 4000K; 4000K is crisper for work, while 3000K suits a kitchen that is open to the living area.

Most important is a consistent colour temperature across all the fixtures in the kitchen and the space open to it; mixing 3000K with 6000K makes the kitchen look like a patchwork of colours.
If the kitchen is open-plan, Tunable White fixtures or dimming scenes allow working light by day and calm light in the evening.

Heat, steam and safety

Near the sink and hob, choose fixtures rated at least IP44.
Fixtures above the hob are usually built into the cooker hood; never place an ordinary spotlight directly over a heat source.
Kitchens in Oman and the GCC see heavy use and high temperatures: choose fixtures with aluminium bodies that dissipate heat, and Drivers with a known warranty.
Fixtures close to grease need an easy-to-clean surface without many openings.
An outdoor or prep kitchen should be treated as outdoors: IP65 or higher.

Checklist before first fix

The final kitchen design (cabinets, island and appliances) before the lighting is laid out.
A power feed for under-cabinet lighting in the right position, and a place for the Driver.
Pendant points measured from the actual centre of the island, not the centre of the ceiling.
Separate circuits: general, task, island, display.
A power feed for lighting inside glass-fronted cabinets, if any.

How to build the layers

Strips under the wall cabinets above the worktops, inside a profile with a diffuser so the dots don’t reflect on the marble.
If the surface is glossy, use a continuous COB strip or an opal diffuser.
General spotlights in a line in front of the cabinets, not in the middle of the ceiling.
Pendants over the island, hung at a height that doesn’t block the view.
Lighting inside glass-fronted cabinets, if any.

Common mistakes: Kitchen

Common mistakeFluorescent colour mistake (Halophosphor)

“Your kitchen is high-end, but the lighting makes it look cheap? The problem is the type of tube!”

The problem: Using old fluorescent tubes (single phosphor) with poor colour rendering
Technical explanation: You should use modern Tri-phosphor tubes, or LED, because their colour accuracy (CRI) exceeds 80 and they give a stronger output
The result: An appetising kitchen, with true, vibrant food colours
