Lighting is the single most important design tool in a living room, it affects mood, perceived size, and how you feel in the home. A well-planned lighting scheme combines three layers and can be controlled via a dimmer or a smart app. Here is the complete guide.
The Golden Rule: Three Layers of Lighting
All lighting designers and interior designers start with three layers:
| Layer | Function | Typical Installation |
|---|---|---|
| 1. General Lighting | Basic light that illuminates the whole room | Recessed ceiling spotlights, flush mount |
| 2. Task Lighting | Directional lighting for specific activities | Floor lamp by reading chair, pendant over workspace |
| 3. Mood Lighting | Soft accent light that eliminates harsh shadows | LED strip, table lamps, uplighter |
A common mistake is having only one layer (a strong ceiling lamp) that is either fully turned on or switched off. The result is a flat and dull room without flexibility.
Layer 1: General Lighting
Recommended amount of light: 3,000–4,500 lumens for a 20–30 m² room.
Color temperature: 2,700–3,000 K (warm white) for an inviting feel.
Recessed ceiling spotlights (downlights) are a very popular choice that provides a clean and modern impression. Place them in an even grid with about 1.2–1.5 meters spacing, at least 60 cm from the wall, for balanced light distribution.
Requirements for a certified electrician: Fixed installation of spotlights in ceilings requires electrical work where new cables, conduits, and drivers are recessed. Expect approx. 3,000–8,000 SEK for a room, depending on the number of spotlights and whether the ceiling is drywall or concrete.
Expert tip: Always install a dimmer on general lighting. It is the single most important upgrade, an affordable investment that completely transforms the room.
Layer 2: Task Lighting
Task lighting should provide directional light and be able to be turned on independently of general lighting:
- Reading chair: Floor lamp with an adjustable head and at least 400 lux on the reading surface.
- Desk and office: Table lamp or pendant positioned to avoid shadows and glare.
- Dining table: Pendant light placed approx. 60–70 cm above the tabletop for optimal light distribution without glare.
Layer 3: Mood Lighting
It is mood lighting that creates depth and character in the room:
- LED strip behind TV furniture: Provides pleasant background lighting that reduces eye strain and improves perceived contrast.
- Uplight behind sofa or plants: Illuminates the wall and ceiling, creating a sense of space.
- Table lamps in windows: Create depth and a warm, inviting impression both inside and out.
- Directional spotlights: Highlight artwork, shelves, or architectural details.
Smart Lighting: Plejd and Automatic Scenes
With Plejd, you can gather the room's entire lighting scheme into ready-made, pre-programmed scenarios:
| Scene | Setting |
|---|---|
| "Movie Night" | Ceiling spots dimmed to 5%, LED strip behind TV in amber |
| "Dinner Party" | Ceiling spots 60%, table lamps on, pendant 80% |
| "Morning" | All lamps to 100% white cool light (3,000 K) |
| "Reading" | Ceiling spots off, floor lamp max, LED strip off |
Scenes are easily activated via a button press, app, motion sensor, or voice control with Google Home or Alexa. Plejd is installed directly behind your existing switches and communicates wirelessly between devices, meaning you don't have to pull new control cables through the walls.
Note: Plejd devices require a neutral wire for power supply. If a neutral wire is missing in the junction box behind the switch, the electrician will need to run one during installation.
What Does a Professional Lighting Installation Cost?
| Action | Price Range (incl. materials) | With ROT Deduction |
|---|---|---|
| 6 ceiling spotlights, new installation | 5,000–10,000 SEK | 4,000–8,000 SEK |
| Dimmer (Plejd or Schneider) | 800–2,000 SEK/ea | 600–1,600 SEK |
| LED strip + connection | 500–1,500 SEK | 400–1,200 SEK |
| Complete Plejd installation (4 rooms) | 15,000–30,000 SEK | 12,000–24,000 SEK |
The ROT deduction provides a 30% discount on labor costs for home electrical installations.
Frequently Asked Questions about Lighting Design
Can I install spotlights in a concrete ceiling?
Yes, the electrician grooves channels or core drills and routes cables in new conduits. It requires more work than in a drywall ceiling, but is fully possible. Prepare for a longer installation time and a higher total cost.
Which dimmer fits my LED lamps?
LED requires an LED-compatible dimmer (trailing/leading edge). Check that the dimmer is marked for LED and handles the low load from your lamps. Universal dimmers from e.g. Plejd or Schneider Wiser work with most dimmable LED light sources.
How many spotlights do I need?
Estimate approx. one spotlight per 1.5 m² of ceiling area in a normal room. For a living room of 25 m² with standard ceiling height, about 6–8 spotlights are needed to achieve good, even basic lighting.
