For KNX, DALI & Loxone dimming projects
Dimmable Single CCT 24V LED Spots for grouped smart-home lighting zones
TILLUME Single CCT spot modules are designed specifically for dimming applications where a KNX, DALI or Loxone system should deliver smooth, predictable brightness control. In grouped zones such as living rooms, corridors, kitchens and bedrooms, they turn KNX, DALI or Loxone dimming commands into the final light output, as long as the controller provides a matching 24V PWM output.
Choose 2850K, 3300K or 4000K, then match the module with a DALI DT6 actuator, KNX dimming actuator, Loxone 24V PWM output or another compatible 24V PWM controller. The same plan should also include the 24V power supply and installation housing. For light quality, TILLUME offers Expert with Ra90 and Master with Ra95 plus strong red rendering with R9 >=92.
Requires a compatible controller or dimming actuator with matching 24V PWM output, channel capacity and zone configuration. A detailed product explanation and selection guide are available below the product list.

Selection guide for dimmable Single CCT 24V LED spots
When to choose Single CCT 24V LED spots
Choose this collection for dimming-focused lighting zones where a KNX, DALI or Loxone project needs smooth brightness control from a matching final 24V PWM output. TILLUME Single CCT spot modules are available in 2850K, 3300K and 4000K for grouped lighting zones that need stable, predictable dimming in a 24V smart-lighting system.
Use them in KNX, DALI or Loxone projects where several spots work together as one dimming zone, for example in living rooms, corridors, kitchens, bedrooms or general interior lighting.
Choose the right CCT
Select 2850K for a warm light impression close to traditional incandescent lamps, 3300K for a balanced warm-neutral effect, or 4000K for clearer and more neutral ambient light.
Select Expert or Master
TILLUME offers two Single CCT quality levels: Expert with Ra90, and Master with Ra95 plus stronger red rendering, including R9 92 at 2850K and up to R9 94 at 4000K. Master is the better choice for faces, wooden furniture, dining tables, kitchen areas and red fabrics.
Match the 24V PWM output
Pair the LED module with a suitable DALI DT6 actuator, KNX dimming actuator, Loxone 24V PWM output or compatible 24V PWM controller. Check channel capacity, channel count, PWM frequency, minimum dimming level, cable length and voltage drop.
How to choose the right color temperature
For dimming scenes, choose the preferred light impression first, then use the control system to adjust brightness according to the room and usage scenario.
Expert Ra90 or Master Ra95: which version fits the project?
Color rendering is visible in real interiors as well as in test reports. It changes how faces, wooden furniture, dining tables, kitchen worktops, red fabrics, artwork and warm decorative surfaces look under artificial light. Expert uses Ra90 for reliable everyday zones. Master uses Ra95 and stronger red rendering, including R9 92 at 2850K and up to R9 94 at 4000K, for rooms where these details are more visible.
2850K spectrum comparison: Master vs Expert
The 2850K Master version is the better fit when color appearance matters. Compared with the Expert version, its spectrum has a smoother transition in the blue-green area and a less pronounced blue peak. This helps faces, wooden furniture, red fabrics and warm interior materials look more natural.
Spectrum comparison of TILLUME 8W 2850K Master full spectrum and Expert 2850K LED spot modules. Use Master for interiors where red tones, warm materials and skin tones need more accurate rendering.
Why the whole 24V setup matters
In a KNX, DALI or Loxone project, the 24V spot module turns the controller output into visible light.
KNX, DALI, Loxone or another platform can provide the control logic. The actual dimming result still depends on the final 24V PWM output, power supply, cable route, installation housing and LED module.
Modular design for installation and maintenance
TILLUME uses a modular 24V spot design based on standard GU10 and MR16 dimensions. The LED module can fit many traditional luminaires when the housing and thermal space are suitable. It can also be planned with TILLUME installation housings, a 24V DC power supply and the actuator or controller output, which makes installation and later maintenance easier.
Stable output across 22-25V input
In 24V constant-voltage lighting systems, long cable runs can reduce the voltage at the spot. TILLUME spot modules keep brightness stable within the specified 22-25V input range. Master versions also add overcurrent protection and soft-start behavior to help reduce inrush current.
Dimming behavior you can plan
TILLUME spot modules support PWM frequencies up to 6 kHz. For most projects, stay below 4 kHz: about 1% minimum dimming is possible at 4 kHz, and about 0.3% at 1 kHz, depending on the controller and system setup.
Light quality options
Choose Expert with Ra90 for reliable general lighting. Choose Master with Ra95 and stronger red rendering for faces, wooden furniture, dining areas, red fabrics and warm interior surfaces. Master reaches R9 92 at 2850K and up to R9 94 at 4000K.
System note: choose by final 24V PWM output, not protocol name alone
DALI, KNX, Loxone and other smart-home systems can all be part of a 24V lighting project, while the LED spot module produces the final light output. For Single CCT dimming, that final stage must provide a suitable 24V PWM output and enough channel capacity for the selected LED modules.
In practice, this can be a DALI DT6 actuator, a KNX dimming actuator, a Loxone 24V PWM output or another compatible 24V PWM controller. Before installation, check total wattage, channel grouping, cable length, voltage drop, power supply reserve, PWM frequency and the required dimming curve.
TILLUME 24V spot modules support PWM frequencies up to 6 kHz. For most projects, we recommend staying below 4 kHz. At 4 kHz, the modules support a minimum dimming level of about 1%; at 1 kHz, they can support about 0.3% minimum brightness, depending on the controller and system configuration.
Planning checklist for grouped dimming zones
Define the room and zone
Decide which spots belong to the same dimming group, such as corridor, kitchen worktop, living room ambient light or bedroom zone.
Choose CCT and quality level
Select 2850K, 3300K or 4000K, then choose Expert Ra90 or Master Ra95 according to the visual quality requirement. For demanding interiors, Master adds strong red rendering, including R9 92 at 2850K and up to R9 94 at 4000K.
Match actuator and power supply
Use a suitable 24V PWM output and a stable 24V power supply with appropriate reserve. Check whether the controller supports the required PWM frequency and minimum dimming level.
Check installation fit
Confirm module format, installation housing, cable route, voltage drop and available space before ordering the final configuration.
Frequently asked questions
Can these 24V LED spots be used in KNX, DALI or Loxone systems?
Yes, if the final output stage provides a suitable 24V PWM output. In practice, this can be a DALI DT6 actuator, a KNX dimming actuator, a Loxone 24V PWM output or another compatible 24V PWM controller. The protocol defines the control logic, while the final light result depends on the 24V PWM output, channel capacity and dimming configuration.
What should I check before connecting several spots to one dimming channel?
Check the total wattage per channel, the actuator or controller channel capacity, the 24V power supply reserve, cable length, voltage drop, PWM frequency and the required minimum dimming level. For grouped dimming zones, all modules on the same channel should be planned with the same color temperature and compatible electrical characteristics.
Why does the 22-25V input range matter in a 24V lighting system?
In low-voltage constant-voltage lighting systems, cable length and voltage drop can reduce the voltage available at the LED module. TILLUME spot modules are designed to keep brightness stable across the specified 22-25V input range, which gives more planning tolerance in real 24V installations.
Which PWM frequency should I use for smooth dimming?
TILLUME spot modules support PWM frequencies up to 6 kHz. For most projects, we recommend staying below 4 kHz. At 4 kHz, the modules support a minimum dimming level of about 1%; at 1 kHz, they can support about 0.3% minimum brightness, depending on the controller and system configuration.
Where does the Master version make a visible difference?
Expert Ra90 is a solid choice for reliable everyday lighting zones such as corridors, utility rooms and general residential areas. Master Ra95 is better suited for areas where color appearance matters more, such as faces, wooden furniture, dining tables, kitchen areas, red fabrics, artwork and premium interior materials. For red-tone rendering, Master reaches R9 92 at 2850K and up to R9 94 at 4000K.
Why is the modular GU10/MR16-based design useful?
The TILLUME LED module is designed around standard GU10 and MR16 dimensions, so it can fit many traditional luminaires when the housing, wiring layout and thermal space are suitable. Because luminaires from different manufacturers can still have small dimensional or thermal differences, we recommend testing a sample before final project installation. TILLUME also offers fully matched housings for projects that need a complete module-and-housing solution.
