DALI-2 Outdoor LED Drivers for Smart and Connected Lighting
FAHOLD DALI-2 outdoor LED drivers are constant-current power solutions developed for professional lighting systems that require digital communication between the LED driver and lighting-control network. Typical applications include smart street lighting, tunnel lighting, area lighting, industrial luminaires and other connected outdoor-lighting systems.
Unlike a driver that only receives a simple analog dimming signal, a DALI-2 driver communicates over a digital lighting bus. This allows compatible lighting-control systems to send commands and, where supported by the driver and project architecture, retrieve operational or monitoring data.
The current FAHOLD DALI-2 outdoor portfolio is based on the F2D platform. It includes 13 models from 75W to 240W with 100–277Vac input, multiple constant-current LED output ranges and IP66 / IP67 outdoor enclosure configurations.
What Is a DALI-2 LED Driver?
A DALI-2 LED driver is control gear designed to operate within a compatible Digital Addressable Lighting Interface system. Instead of controlling light output only through an analog voltage signal, DALI uses digital communication between lighting devices and the control system.
This digital architecture allows compatible luminaires to be addressed, grouped and controlled as part of a wider lighting network. Depending on the implemented DALI functions, the system can also support information exchange for commissioning, energy monitoring, diagnostics and maintenance.
DALI-2 compatibility should always be evaluated as part of the complete control system. The application controller, bus architecture, sensors, gateways and LED drivers must support the functions required by the project.
DALI-2 Drivers for Smart Street Lighting
Street-lighting projects increasingly require more than simple ON/OFF operation. Digital control can allow luminaires to operate according to schedules, lighting zones, traffic conditions or centralized management strategies.
A DALI-2 street-light driver can form part of this architecture by providing digitally controlled LED output and communication with the compatible lighting network.
FAHOLD F2D provides power options from 75W to 240W for compatible roadway and street-light fixtures using different LED voltage and current architectures.

DALI-2 Drivers for Tunnel Lighting
Tunnel-lighting systems often require different illumination levels across entrance, transition, interior and exit zones. Digital lighting control can help manage these zones as part of a coordinated tunnel-lighting system.
F2D provides several LED voltage and power configurations for compatible tunnel luminaires while supporting digital DALI-2 control, programmable output and outdoor enclosure protection.
When selecting a tunnel-light driver, LED voltage, required current, power, control-network architecture, surge environment, IP protection and thermal conditions should all be considered together.
DALI-2 Drivers for Area and Industrial Lighting
Digital lighting control is also relevant to parking areas, industrial sites, logistics facilities, high-bay systems and large commercial outdoor spaces where multiple luminaires need coordinated control and monitoring.
The F2D platform combines constant-current LED power with digital control functions, allowing compatible fixtures to become part of a broader lighting-management infrastructure.
Current F2D DALI-2 Driver Range
The current FAHOLD DALI-2 category includes 13 F2D models across five main power classes.
| Power Class | Available Output Platforms | Typical Selection Direction |
|---|---|---|
| 75W | 27–54Vdc / 60–115Vdc | Lower-power street, tunnel and industrial luminaires |
| 100W | 27–54Vdc / 60–143Vdc | Commercial outdoor fixtures using low- or medium-voltage LED strings |
| 150W | 27–54Vdc / 72–143Vdc / 107–214Vdc | Street, tunnel and industrial lighting with multiple LED architectures |
| 200W | 27–54Vdc / 72–143Vdc / 140–286Vdc | Higher-output roadway, area and industrial luminaires |
| 240W | 27–54Vdc / 114–228Vdc / 171–343Vdc | High-output street, tunnel and professional outdoor lighting |
These output ranges belong to different F2D models. They do not represent one universal driver with a continuous 27–343V output range. The correct model must contain the complete operating-voltage and current range of the connected LED module.
100–277Vac DALI-2 Outdoor LED Drivers
All current F2D models use a 100–277Vac rated-input platform. This allows compatible luminaires to operate across common commercial lighting supplies such as nominal 120V, 208V, 220–240V and 277V.
Wide AC input can simplify development of professional outdoor luminaires intended for multiple electrical environments.
AC input voltage should not be confused with LED output voltage. A luminaire connected to a 277Vac supply may use an F2D driver that provides 27–54Vdc, 72–143Vdc or a much higher LED output window depending on the LED-board architecture.
Constant-Current DALI-2 LED Drivers
F2D is a constant-current LED driver platform. The driver regulates LED operating current while allowing the output voltage to vary within the supported range of the selected model.
This is important because two luminaires with the same rated wattage can use very different LED-string voltages and currents.
For accurate model selection, provide the LED module's minimum, nominal and maximum forward voltage together with required operating current and maximum electrical power.
Digital Dimming with DALI-2
DALI-2 provides digital control of the LED driver rather than relying only on an analog dimming voltage. Compatible lighting controllers can send digital commands to control luminaire output through the DALI network.
Digital communication allows luminaires to participate in a structured lighting-control architecture where device addressing, grouping and coordinated operation can be managed by the compatible control system.
The exact available functions depend on the driver implementation and the wider lighting network, so project requirements should be defined before driver and controller selection.
DALI-2 vs 0–10V Outdoor LED Drivers
Both DALI-2 and 0–10V can control light output, but their system architectures are fundamentally different.
| Feature | DALI-2 | 0–10V |
|---|---|---|
| Control Method | Digital communication | Analog control voltage |
| Device Addressing | Supported within compatible DALI systems | Generally controlled by analog wiring zones rather than individual digital addresses |
| Two-Way Communication | Supported by the DALI communication architecture | Standard analog 0–10V dimming is primarily a control-signal interface |
| Data / Monitoring Direction | Available when implemented by compatible DALI driver and system functions | Requires separate monitoring architecture if needed |
| Typical Project | Connected street lighting, smart outdoor lighting and digitally managed installations | Conventional street, tunnel and commercial dimming systems |
Choose the control architecture according to the project controller, commissioning method, monitoring requirements, wiring strategy and maintenance plan rather than assuming one protocol is universally better.

Online Programmable DALI-2 LED Drivers
The F2D platform supports online output-current programming. This allows compatible project tools and control architecture to configure supported driver parameters within the permitted electrical operating range.
Programmable current can help OEM luminaire manufacturers use one electrical platform across several fixture variants while matching the driver more precisely to different LED modules.
The programmed operating point must remain within the voltage, current, power and thermal limits of the selected F2D model.
Optional NFC Programmable LED Drivers
F2D also provides an optional NFC programming configuration. NFC can simplify parameter configuration during manufacturing or luminaire setup without requiring the same wired programming process for every unit.
In the current configuration direction, the standard version is supplied without NFC while the optional F version includes NFC capability.
NFC requirements should be specified during project development because it is an optional configuration rather than a feature that should be assumed on every supplied driver.
Power Monitoring for Connected Outdoor Lighting
F2D is designed for connected-lighting projects where driver operating information can provide additional value beyond dimming alone.
Current F2D product documentation includes power-monitoring functionality. This can support smart-lighting applications where operational information is used for energy analysis, asset management or maintenance workflows.
The exact data available to the lighting network depends on the implemented DALI functions and the complete control-system architecture.
DALI Part 251 Luminaire Data
The current F2D product documentation identifies support for DALI-2 certification including Parts 251, 252 and 253.
DALI Part 251 relates to luminaire data. Compatible implementations can store standardized information associated with the luminaire, helping support asset identification and lighting-system management.
DALI Part 252 Energy Reporting
DALI Part 252 defines standardized energy-reporting data. Compatible control gear can provide information related to electrical power and energy use through the DALI system.
For outdoor-lighting owners, energy data can support centralized monitoring of large lighting installations and improve visibility into system operation.
DALI Part 253 Diagnostics and Maintenance Data
DALI Part 253 addresses diagnostic and maintenance information. Compatible implementations can provide operational data and failure-related information that may support preventive maintenance and asset-management strategies.
This is particularly relevant to street, tunnel and industrial-lighting systems where luminaires may be distributed across large areas and physical inspection can be costly.
DALI-2 Data and D4i Are Not the Same Claim
DALI Parts 251, 252 and 253 can be implemented within DALI-2 control gear and provide luminaire, energy and diagnostics data. However, D4i certification has additional mandatory requirements.
A project should therefore verify the exact required certification and feature set rather than assuming that support for DALI data automatically means every driver is D4i-certified.
Dim-to-Off for Outdoor Lighting
F2D supports Dim-to-Off functionality, allowing compatible lighting systems to command the LED output to a true off state rather than leaving residual light at the bottom of the dimming range.
This can be useful for scheduled outdoor lighting, industrial sites and energy-management strategies where luminaires must turn fully off during selected periods.
Low Standby Power for Smart Lighting
Current F2D product documentation specifies standby power below 0.5W. Low standby consumption is relevant to digitally controlled lighting because the driver may remain connected to the control system even when LED output is switched off.
Across large connected-lighting installations, driver standby consumption can become a meaningful system-design consideration.
75W DALI-2 Outdoor LED Drivers
The current 75W F2D group provides two LED output directions: 27–54Vdc for lower-voltage higher-current LED arrays and 60–115Vdc for longer LED strings operating at lower current.
These models are suitable for compatible lower-power street, tunnel, pathway, industrial and outdoor luminaires that require digital DALI-2 control.
100W DALI-2 LED Drivers
F2D provides 100W products with 27–54Vdc and 60–143Vdc output windows.
The two configurations allow a 100W luminaire designer to choose between a lower-voltage higher-current LED architecture and a higher-voltage lower-current LED-string design.
150W DALI-2 Street and Tunnel Light Drivers
The 150W F2D platform provides three output-voltage directions: 27–54Vdc, 72–143Vdc and 107–214Vdc.
This wider electrical selection makes the 150W class relevant to several professional street, tunnel and industrial-lighting architectures while retaining the same digital-control direction.
200W DALI-2 Outdoor LED Drivers
The 200W group includes 27–54Vdc, 72–143Vdc and 140–286Vdc configurations.
These models cover high-current lower-voltage LED boards through longer high-voltage LED strings, allowing fixture manufacturers to match the driver to the LED architecture rather than redesigning the LED board around one fixed output range.
240W DALI-2 High-Power LED Drivers
The current 240W F2D group includes 27–54Vdc, 114–228Vdc and 171–343Vdc output platforms.
The 171–343Vdc configuration provides a high-voltage lower-current option for high-output outdoor luminaires, while the 27–54V model serves substantially higher-current LED-board architectures.
This demonstrates why a search for a “240W DALI-2 LED driver” must still be narrowed by LED voltage and current before model selection.
IP66 and IP67 DALI-2 Outdoor LED Drivers
Current F2D products provide IP66 / IP67 outdoor enclosure configurations. These ratings support professional outdoor and industrial applications where dust and moisture protection are important driver requirements.
The driver IP rating applies to the driver enclosure or selected configuration. Connectors, cables, cable entries, seals, luminaire housing and installation conditions must also provide the required protection for the finished fixture.
Surge Protection for DALI-2 Outdoor Lighting
Outdoor lighting installations can be exposed to switching transients, long cable runs and lightning-related electrical disturbances.
Current F2D product documentation specifies differential-mode surge protection up to 6kV and common-mode protection up to 10kV.
Driver-level surge capability should be coordinated with facility grounding and system-level surge-protection design, particularly in street, tunnel and large outdoor-lighting projects.
Electrical Protection Functions
The F2D platform includes short-circuit, over-temperature, over-voltage and overpower protection functions.
These functions help protect the driver during abnormal operating conditions but do not replace correct LED-board design, fixture thermal management, branch protection, grounding or overall electrical-system engineering.
Protection Class I and Class II Luminaire Support
Current F2D documentation identifies the platform as suitable for compatible Protection Class I and Class II luminaire configurations.
The final protection class is a characteristic of the complete luminaire design and must be evaluated together with insulation, grounding, wiring, enclosure construction and applicable certification requirements.
DALI-2 LED Driver Efficiency and Power Factor
Current F2D models specify power factor above 0.95. Typical efficiency varies according to power and output-voltage configuration, from approximately 89% on selected 75W and 100W models to approximately 96% on the high-voltage 240W platform.
Actual efficiency depends on AC input voltage, LED operating point, output current and thermal conditions. Model-level efficiency should therefore be reviewed when evaluating the final luminaire design.

DALI-2 vs Conventional Non-Dimmable Outdoor Drivers
A conventional non-dimmable outdoor driver primarily provides regulated LED power and simple ON/OFF operation. A DALI-2 driver adds a digital communication layer for compatible networked lighting-control systems.
DALI-2 is therefore most relevant when the project requires centralized control, digital addressing, programming, monitoring or a more structured smart-lighting architecture.
