How many recessed spots do I need?
As a rule of thumb one spot per one and a half square metres at a 2.60-metre ceiling. For a 24 m² living room that is about sixteen spots — but in practice we often use twelve to fourteen on two switch groups, topped up with wall lights and an LED strip.
With a higher ceiling spacing can be larger and the count smaller, because the beam widens as it travels. Use the calculator at the top of this page: it accounts for area, ceiling height and what the room is for.
What does fitting recessed spots cost?
€ 95 per spot including 21% VAT. That covers drilling the hole, wiring, connecting, aligning and testing. In a concrete or old plaster ceiling add € 22 per spot for heavier drilling.
You buy the spots separately: allow €15 to €60 each. A complete set of ten spots with dimmer, fitted and connected, costs €1,150. A lighting plan for the whole home costs €395.
Which colour temperature should I choose?
In living rooms 2,700 kelvin — warm light, pleasant to sit in. Above a worktop, in the bathroom and in the hall 3,000 kelvin: a little cooler, so you see more sharply and colours render better. In a study 3,000 to 4,000 kelvin can work.
Also watch the colour rendering index, CRI. Cheap spots sit around CRI 80, where a timber floor looks dull and food colour is off. CRI 90 or higher costs a few euros more per spot and is the difference you see every day.
Why does my dimmer flicker?
Almost always because the dimmer does not match the LED driver. There are leading-edge dimmers, designed for incandescent lamps, and trailing-edge ones for electronic drivers such as in LED spots. The wrong pairing causes flicker, incomplete switch-off or a faint afterglow.
A second cause is minimum load: many dimmers have a lower limit of, for example, ten watts. Replace five 50-watt halogen spots with 5-watt LEDs and you go from 250 to 25 watts and sit on the edge. We choose the dimmer based on the spots you take, and replace it free of charge if it still flickers.
Can spots go in a concrete ceiling?
Usually not without a suspended ceiling. Solid concrete lacks recess depth, and drilling into reinforcement is not an option. If there is insulation under the concrete, it often works with shallow-recess spots.
Alternatives are surface spots, a track system or a suspended ceiling. The last costs more, but also gains you space to hide cables, better acoustics and freedom to place spots where you want. At a ceiling of 2.80 metres or higher you barely notice those ten centimetres.
How far from the wall should spots sit?
At least sixty centimetres, otherwise you get a light patch on the plaster instead of light in the room. Roughly one to one and a half metres apart with a 2.60 m ceiling.
If you want to wash a wall — a bookcase or artwork, for example — that is a separate layer with its own spots closer to the wall and a narrower beam. Put those on their own switch, because you do not always want that light on.
Do you install spotlights for English-speaking clients?
Yes. Installing a recessed spotlight costs € 95 including 21% VAT — drilling, wiring, connecting, aligning and testing — plus € 22 per spot in concrete or old lath-and-plaster ceilings. The fittings themselves cost € 15 to € 60 each and you can buy them yourself or through us without a mark-up.
Rule of thumb: one spot per 1.5 m² with a 2.60 m ceiling, at least 60 cm from the wall, spread over two switched groups. We choose the dimmer to match the drivers of the spots you pick — that is what stops LED flicker.
