MOSO 40W Driver DALI-2+D4I AstroDim 176–305V for LED Street Light

Why choose the MOSO 40W DALI-2 D4i AstroDim driver

Street lighting networks demand more than simple on/off switching. This MOSO driver combines DALI-2 bidirectional communication, D4i device-level data logging, and autonomous AstroDim time-based dimming in a single unit, giving installers and facility managers a complete control solution without additional external controllers or timers. The wide 176–305V input range makes it suitable across varying European grid conditions.

• Smart dimming: AstroDim stores an on-board astronomical clock schedule, so luminaires dim and brighten automatically according to time of night without any external signal.
• DALI-2 + D4i compliance: Full bidirectional DALI-2 communication allows individual addressing, group control, and real-time feedback, while D4i enables energy metering and driver diagnostics at device level.
• Wide input voltage: The 176–305V AC input range accommodates grid fluctuations and varying supply standards across EU member states without additional voltage conditioning.
• Warranty and support: Backed by Clightstore's 5-year warranty, with stock held locally for fast replacement and technical support available for integration queries.

Where to use it

This driver is specified for LED street light columns on urban roads, residential streets, car parks, industrial access roads, and cycle paths where a managed lighting network is in place or planned. It suits retrofit projects upgrading existing columns to smart controls, as well as new installations where DALI-2 infrastructure or standalone AstroDim scheduling is required to meet energy reduction targets.

What the specifications mean in practice

• 40W output: Sized for mid-range street luminaires, delivering sufficient power for typical road and car park LED modules without oversizing the driver compartment.
• DALI-2: The current standard for addressable lighting control, ensuring interoperability with any certified DALI-2 controller or gateway on the market.
• D4i: Enables the driver to report energy consumption, operating hours, and fault status directly to a building or city management system, supporting maintenance planning.
• AstroDim: An internal astronomical timer dims the luminaire on a pre-programmed profile each night, reducing energy use during low-traffic hours with no network dependency.
• 176–305V input: Covers the full range of European supply voltages including areas with known voltage instability, protecting the driver and connected LED module from supply variations.

Installation and compatibility

The driver fits within standard street light column gear trays and connects via the luminaire's DALI bus wiring. AstroDim profiles are configured using MOSO's setup tool or a DALI-2 controller. Compatible with DALI-2 gateways from major network vendors. Clightstore provides a free DIALux light study to confirm luminaire and driver selection for your road classification.
