The eldoLED SOLOdrive 20W Compact LED Driver represents a versatile, programmable constant-current solution for professional LED lighting systems, offering exceptional dimming precision and extensive configurability. It supports dimming protocols such as DALI-2, 0–10V, LEDcode, and PulseDim, allowing seamless integration into a wide range of lighting control ecosystems. This driver family achieves deep dimming down to 0.1%, creating smooth, flicker-free transitions that emulate the warmth and comfort of traditional incandescent and halogen dimming curves through Dim to Warm technology. The SOLOdrive family ensures natural ambiance across various applications, whether in architectural, commercial, or residential lighting environments.
The 20W compact driver operates on universal input voltage ranges between 120 and 277V, while European versions function at 220–240VAC and support central battery emergency systems. Its small, plastic housing is optimized for European downlighting, allowing installation through apertures as small as 45 mm, making it ideal for compact luminaires such as downlights, pendants, and spotlights. The SOLOdrive line also includes ECOdrive models that dim to 1%, SOLOdrive models that reach 0.1%, and DUALdrive variants that enable Tunable White control. This flexibility makes the family suitable for both standalone use and integration into sophisticated control networks.
The eldoLED SOLOdrive driver family supports multiple control interfaces, including DALI-2 DT6 and DT8, 0–10V, PulseDim, Phase dimming, and LEDcode2. The DALI and 0–10V versions include an LEDcode interface that allows precise configuration through eldoLED’s FluxTool software. This tool enables users to fine-tune driver parameters such as dimming curves (logarithmic, linear, soft-linear, or square), minimum dim levels (adjustable in 0.1% increments), and LED output current with 1 mA resolution. Phase dimming versions allow easy current selection through a four-position dipswitch. The driver’s hybrid HydraDrive technology ensures smooth, flicker-safe performance suitable for environments where visual comfort and stability are critical—such as television studios, healthcare facilities, and security camera applications.
Performance and reliability are central to the SOLOdrive 20W design. It delivers constant current SELV output with low inrush current, minimal harmonic distortion, and consistent performance across an ambient operating temperature range of –20°C to +50°C for DALI and 0–10V versions (–20°C to +45°C for phase dimming). With a rated lifetime of 50,000 hours at maximum case temperature, the driver’s lifespan can effectively double for every 10°C reduction in case temperature, contributing to reduced maintenance and longer fixture service life.
Safety and protection mechanisms are integrated comprehensively. The driver automatically reduces LED output current when internal temperatures exceed a predefined threshold and restores normal operation once temperatures normalize. In cases of short circuit, open circuit, or overload, the system responds by cutting or scaling down output current and attempts automatic recovery every 400 milliseconds. Reverse polarity protection prevents current flow when wiring is misconnected, safeguarding both the driver and LED modules.
Thermal protection for the LEDs is managed through an optional external NTC thermistor connected via LEDcode/NTC terminals. When the thermistor detects excessive heat beyond the user-defined limit (default 70°C), the driver reduces output current by 75% to protect the LED array. The system supports standard thermistors such as Vishay’s 47kΩ models (P/N 238164063473 or NTCASCWE3473J), allowing straightforward integration into thermal management designs.
The SOLOdrive compact series aligns with modern lighting control trends by supporting wireless communication options such as Bluetooth and Casambi, enabling remote configuration and dynamic control. When connected to a Casambi module, DALI-2 DT6 models extend their functionality into intuitive, app-based ecosystems suitable for smart architectural environments.
By combining deep dimming precision, compact form factor, extensive configurability, and robust protection mechanisms, the eldoLED SOLOdrive 20W Compact LED Driver stands out as a professional-grade solution for architectural and commercial lighting applications that demand precise control, smooth dimming performance, and dependable reliability across diverse installations.
