1Keuzeprincipe: eerst de toepassing bepalen, daarna 6W of 8W kiezen

De eerste keuze is niet welk wattage sterker klinkt, maar of de ruimte behoefte heeft aan Fixed CCT with dimming or Tunable White. Pas daarna wordt de keuze tussen 6W en 8W zinvol.

Bij Fixed CCT kiest u één kleurtemperatuur, bijvoorbeeld 2850K warm wit of 4000K neutraal wit, en regelt u daarna de helderheid. Een 6W LED spot past vaak in hal, slaapkamer, badkamer en gematigde basisverlichting. Een 8W LED spot is nuttig voor keukens, eetgedeeltes, werkvlakken, grotere ruimtes, hogere plafonds of hogere luxdoelen.

Bij Tunable White is wattage alleen niet genoeg. Twee kleurkanalen worden gemengd; de beschikbare helderheid verandert met kleurtemperatuur en controllerlogica. Bepaal eerst de kleurtemperatuur van de helderste scène en controleer dan de maximale lichtstroom op dat punt. Hogere kleurtemperaturen ogen vaak helderder dan lagere bij dezelfde gemeten lumenwaarde.

Een 4W+4W Tunable White spot zoals de TILLUME Expert 81061M04 is een speciaal geval. Behandel hem niet als gewone 4W-oplossing voor kleine ruimtes en ook niet als conventionele 8W spot.

3Waarom watt alleen niet genoeg is

Watt beschrijft elektrisch verbruik. Lumen beschrijft zichtbare lichtopbrengst. Voor ruimteplanning ligt lumen dichter bij de echte vraag: wordt de ruimte helder genoeg?

Lighting design also works with layers: general lighting, accent lighting and additional or functional lighting. TILLUME LED spots mainly provide broad general light. In real projects they Ze worden vaak gecombineerd met LED strips, onderkastverlichting of andere armaturen voor werkbladen, nissen, schappen, trappen of donkere zones.

• General lighting: overall room brightness, often using wide-beam ceiling spots.
• Accentverlichting: targeted light for pictures, shelves or niches. Narrower optics are better than broad 60° algemene verlichting spots.
• Functionele verlichting: extra licht waar algemene verlichting niet genoeg is, bijvoorbeeld LED strips onder keukenkasten, in schappen, op trappen of in indirecte plafond- en wanddetails.

Zelfs lumen alleen is niet genoeg. Doellux, ruimteoppervlak, stralingshoek, spotafstand, oppervlakken, plafondhoogte, dimmen, scènes en bij Tunable White ook de controllerlogica bepalen samen het resultaat.

4Lumen, lux en ruimtegrootte: zo rekent u correct

Benodigde lumen = ruimteoppervlak in m² × doelverlichtingssterkte in lux
Aantal spots = benodigde lumen ÷ maximale lumen per spot

Use maximum lumens because the system must reach the target lux value at full brightness. In everyday use it will usually be dimmed down depending on the scene.

Voorbeeld: een woonkamer van 12 m² with 150 lx basic lighting needs about 1800 lm. With 600 lm per 6W spot, that is roughly three spots. In a bright room with white walls and normal ceiling height this can work well; dark surfaces, timber ceilings or 3 m ceiling height may require more spots, 8W spots or additional light layers.

Keukenvoorbeeld: 10 m² with a 400 lx target needs about 4000 lm. With 800 lm per 8W spot, that is about five spots. In practice, the worktop may still need under-cabinet lights, LED strips or carefully placed spots. A layered concept is often best: spots provide general light, LED strips add direct light on the work surface.

5Richtwaarden per ruimte: 6W of 8W?

At the same target illuminance, 6W and 8W lead to different planning approaches. 8W spots need fewer light points and can create more depth and contrast. 6W spots usually need more light points but create calmer, more even illumination. Both approaches can be correct.

6Speciaal geval 81061M04: waarom 4W+4W niet automatisch een normale 8W spot is

The TILLUME Expert 81061M04 is a special 4W+4W Tunable White spot with 2200–6500K. It should not be planned as a general 4W spot for small rooms and not as a conventional 8W spot.

This behaviour must not be transferred to other TILLUME Tunable White spots. Other 6W+6W or 8W+8W models are not automatically intended to run both channels permanently at full power.

724V-systeemplanning: voeding, controller en reserve

In a 24V LED spot system, planning does not end with watts per spot. 24V DC power supply, controller channel, cable length and spot must fit together.

Total spot load = number of spots × watts per spot
Recommended PSU power ≈ total load × 1.2

That equals about 20% reserve. A blanket 50% reserve is usually not required in normal projects and can lead to oversized power supplies. A 24V DC power supply should still not be operated permanently above its rated power.

TILLUME 24V power supplies offer two relevant advantages: adjustable output voltage to compensate realistic cable losses in correctly planned installations, and internal design reserve at rated load. This does not mean the rated power may be exceeded permanently; it means the installation has more practical tolerance for cable losses and operation at nominal load.

Also check: maximum power per LED controller channel, number of channels for Tunable White, PWM frequency and dimming behaviour, cable length, cable cross-section, room groups and whether the Tunable White controller uses Wattage Balance, constant power or a special mode such as MDT AKD-0424R Max wattage output.

8Spanningsval en minimale ingangsspanning

With longer 24V cable runs, total power is not the only issue. The input voltage directly at the spot also matters. Every cable causes voltage drop. If too little voltage reaches the end, a poorly planned 24V system may become visibly dimmer.

TILLUME 24V LED spots contain internal constant-current regulation. As long as the input voltage at the spot does not fall below the specified minimum, the internal driver can supply the LED stably. This makes the system more tolerant of realistic cable losses, but it does not replace correct planning of cable cross-section, cable length and power supply.

9Expert of Master: helderheid is niet het enige verschil

Master is not simply “brighter”. The better reason for Master is light quality: stronger colour rendering, a smoother spectrum and stable thermal behaviour, especially with wood, food, skin tones and textiles. Relevant spot families can be found in the 24V LED Spots Expert Collection.

10Veelgemaakte planningsfouten

• Fout 1: 8W is always better than 6W. 8W gives more reserve and needs fewer points, but in small rooms it can cause glare or islands of light. 6W with more points often looks calmer and more even.
• Fout 2: choosing spots only by watts. Watt is electrical input. Planning needs lumen, target lux, beam angle, room area and light distribution.
• Fout 3: planning a keuken like a woonkamer. Keukens and work surfaces often need higher lux values and additional functional light such as LED strips.
• Fout 4: treating 4W+4W as a normal 8W spot. With 81061M04, usable output depends strongly on controller logic.
• Fout 5: choosing the PSU too tightly. A 24V DC supply should not run constantly at its limit; about 20% reserve is a better practical rule.

11Beslissingschecklist

• Welke oppervlakte en welk doel-luxniveau zijn gepland?
• Are the surfaces bright or dark?
• How high is the ceiling?
• Should the spot provide general light, zone light or accent light?
• How many spots fit mechanically and visually into the ceiling?
• Is Fixed CCT with dimming enough or is Tunable White required?
• How many lumens does the spot deliver in the desired colour-temperature range?
• How much power can the controller channel provide?
• How large must the 24V DC power supply be with about 20% reserve?
• How long are the cable runs and what cable cross-section is used?
• For 81061M04: is MDT AKD-0424R Max wattage output really used?
