Domakihub Convert a Ceiling Light to Spotlights: A Clear Guide
Understand the full process before your electrician arrives — and know what you can safely do yourself.

Converting a single ceiling light to a cluster of recessed spotlights or downlights is one of the most impactful lighting upgrades you can make — transforming a dim, flat room into a well-lit, modern space. The video above shows the physical installation in real time, while this guide walks through every decision: choosing fixtures, planning the layout, understanding what needs a licensed electrician, and how to prepare so the job goes smoothly. Whether you are upgrading a holiday villa in Crete, an Athens apartment, or a hotel room, the same principles apply.
Why Spotlights Beat a Single Ceiling Rose
A single pendant or ceiling rose spreads light unevenly — bright directly below, dark at the walls. Recessed LED spotlights (also called downlights or can lights) let you place light exactly where you need it: over a dining table, a work surface, a reading corner, or a bathroom vanity. The result is even illumination without the harsh glare of a single bright source.
In Greek rental properties and hotels, spotlights also read as 'premium' to guests. They eliminate the institutional look of a bare bulb or a cheap flush mount, and LED versions consume 70–80 % less energy than the incandescent or halogen fittings they replace — an important consideration given Greek electricity tariffs.
What the Law Says: When You Must Call an Electrician
In Greece, all mains electrical work — connecting, disconnecting, or extending fixed wiring inside walls and ceilings — must be performed by a licensed electrician (ηλεκτρολόγος with a valid ΓΣΕΕ licence). This includes running new cable from a junction box to multiple spotlight positions. The homeowner or property manager is legally responsible for ensuring a qualified professional issues the required electrical certificate (Υπεύθυνη Δήλωση Ηλεκτρολόγου) after any fixed wiring work. Skipping this step creates liability issues with insurance and short-term rental platforms.
What you can typically do yourself: choose fixtures, plan the layout on paper, cut ceiling holes in plasterboard (once power is confirmed off), and snap in LED modules after an electrician has wired and capped the cables. When in doubt, keep the electrician on site for the full job — it is usually only a few hours' labour.
How the Conversion Works: 5 Key Steps
- 1
Plan the spotlight layout before touching anything
Decide how many spotlights you need and where. A standard rule of thumb is one downlight per 1–1.5 square metres of ceiling area for general lighting, positioned at least 30 cm from walls. Sketch the room to scale and mark the positions. Check what is above the ceiling — a concrete slab (common in Greek construction) means you cannot recess standard downlights without a false ceiling or a surface-mount solution; a plasterboard or suspended ceiling gives you the easiest path. Also check for joists, pipes, and existing wiring before committing to hole positions.

Turn off the power and verify the existing wiring
Your licensed electrician will isolate the circuit at the consumer unit (πίνακας) and use a voltage tester to confirm the ceiling rose is dead before opening it. They will inspect the existing cable: older Greek buildings often have 1.5 mm² or 2.5 mm² twin-and-earth, which is adequate for a lighting circuit. They will also identify whether the existing supply cable runs to a loop-in ceiling rose or through a junction box, because this determines how the new multi-spotlight circuit is laid out.

Cut the holes and route new cable
With the layout confirmed and power off, cut the circular holes for each downlight housing using a hole saw matched to the fixture's cut-out diameter (typically 65–95 mm for standard GU10 LED downlights). Feed new 1.5 mm² heat-resistant cable from the existing supply point to each spotlight position — either daisy-chained (looped from one to the next) or home-run (each on its own cable back to a junction box). Your electrician handles all cable connections. In a concrete ceiling, surface-mounted conduit or a slim false ceiling is the practical route.

Install the downlight housings and connect the fittings
Each downlight housing clips or screws into the ceiling hole. Spring-loaded clips on most modern fittings grip the plasterboard from behind — no separate backbox needed for standard recessed models. Your electrician connects the live, neutral, and earth conductors at each fitting's terminal block or connector, caps the junction boxes, and checks polarity. Fire-rated downlights (with an intumescent ring that expands if heat is detected) are strongly recommended for any room with a timber structure above, and are required by many insurance policies in rental properties.
- 5
Test, adjust the beam angle, and commission
Once all connections are made, restore power and test each spotlight individually. Most GU10 LED spotlights have a fixed beam angle (36° is the standard general-purpose angle; 24° gives a tighter, more directional beam for accent lighting). If you chose adjustable or tilting fittings, angle them now. Dimmable spotlights require a compatible trailing-edge LED dimmer — confirm this before buying bulbs. Finally, your electrician signs and issues the Υπεύθυνη Δήλωση, which you should keep on file for insurance and any future property sale.

FAQ
- Can I convert a ceiling light to spotlights in a concrete ceiling?
- Yes, but you cannot recess fittings into concrete. The standard solution in Greece is to install a slim plasterboard false ceiling (about 10–12 cm drop) below the concrete slab, which hides the wiring and provides the depth for standard recessed downlights. Alternatively, surface-mounted spotlight tracks or semi-recessed fittings designed for shallow ceiling voids are available and require less structural work.
- How many spotlights should replace one ceiling light?
- A single pendant or flush mount is typically replaced by 4–9 downlights depending on room size. For a 12 m² bedroom or living area, 4–6 spotlights at 5–7 W each (GU10 LED) provide comfortable general lighting. For kitchens and bathrooms where task lighting matters, lean toward more fixtures or add directional accent lights over work surfaces.
- Will the existing wiring handle multiple spotlights?
- In most cases, yes. A standard 6 A lighting circuit in a Greek property is rated for around 1,380 W, and modern LED spotlights draw only 5–7 W each, so even 10 spotlights use less than 70 W total — a tiny fraction of the circuit's capacity. Your electrician will confirm the circuit rating and check that the cable condition and connections meet current standards before signing off the work.
