The LED Module 520 is the simple solution for the energy-efficient and sustainable refurbishment of technically obsolete road luminaires with modern, cost-optimised and CO₂-optimised LED lighting technology. The LED Module 520 replaces the gear tray with conventional lighting technology for the luminaires CITY LIGHT PLUS, CITY LIGHT ELEGANCE, LANTERN, LANTERN CLASSIC, LANTERN DELUXE, MUSHROOM LUMINAIRE, CITY LIGHT BOLLARD 120 and 120 E as well as CITY LIGHT PILLAR 260, 260 E and 260 D. The modular construction ensures that later, more modern and higher-performance LED generations can be retrofitted and used with ease. For taking complete advantage of the performance potential of the LED Module 520, we recommend combining it with a transparent luminaire cover when refurbishing obsolete systems.
The LED Module 520 based on the Siteco gear tray technology has symmetric or asymmetric light distribution and is available either with warm white or neutral white colour temperatures. It consists of a precisely matched combination of high performance LEDs, optical lens systems, highly specular reflectors and microprocessor-controlled LED operating electronics. This in turn makes available a series of additional functions. These functions have been combined into three various functional packages: Basic, Plus and Premium. All make use of the outstanding property of LED light sources in reducing luminous flux without loss. These values are either factory-set (Basic variant), can be individually set with the Siteco® Service Box (Plus variant) or centrally set via Street Light Control (Premium variant). The Plus and Premium versions offer the widest spectrum of efficient, user-dependent control and monitoring of the LED luminaires.
Basic performance package:
Temperature monitoring for protection of LEDs from thermal overload | luminous flux reduction via 230V control voltage
Plus performance package:
Luminous flux constancy over complete service life | integrated, programmable timer for reduction of luminous flux in two steps | settable luminous flux for max. operation and for both reduction levels | all parameters can be set with the Service Box | can be additionally integrated via SDI into existing digital control systems and controllable from a central control point | temperature monitoring for protection of LEDs from thermal overload | alternative luminous flux reduction via 230V control voltage
Premium performance package:
Street Light Control: for individual monitoring and control of the luminaire from a central control point from any distance via LON PowerLine without supplementary control wire (instead of SDI) | further functional spectrum as with Plus variant.

• innovative, energy-efficient technology with 100% compatibility to the CITY LIGHT, LANTERN and MUSHROOM LUMINAIRE families
• low installation effort and simple replacement via Siteco gear tray technology
• LED operating electronics with wide range of functions for efficient control of luminous flux
• standardised streetlighting according to DIN EN 13201
• light colours: warm white or neutral white
• high level of visual comfort thanks to glare reduction via light dispersing element (spreader) for reduction of luminance
• asymmetric or symmetric light distribution
• efficient physical and electronic thermal management for high product service life

The LED Module 520 is 100% compatible to the gear trays of CITY-LIGHT, LANTERN and MUSHROOM LUMINAIRE in all versions | outer housing of sheet steel, metallic grey (RAL 9006) | heat sink of extruded aluminium | reflector of high-performance polymer, highly specular vapourised | complete unit for replacement of gear tray with conventional light sources

Connection of LED module versions:
Basic performance package: LED module with 3-pole connection terminal, max. 2.5mm² (2-pole for mains supply + 1-pole for 230V control voltage for power reduction) | control signal: U_St= 230V --> 100% luminous flux; U_St= 0V --> approx. 50% luminous flux
Plus performance package: LED module with 5-pole connection terminal, max. 2.5mm² (2-pole for mains supply + 1-pole for 230V control voltage for power reduction + 2-pole for Siteco® Digital Interface (SDI)) | SDI for parameterising of luminaire with Siteco® Service Box (with integration of luminaire into digital control system on request) | alternative luminous flux reduction via 230V control voltage
Premium performance package: LED module with 2-pole connection terminal, max. 2.5mm² (control and monitoring of the luminaire from a central control point without supplementary control wires; data transmission according to standardized LON protocol)


LED Module 520 can be operated with factory pre-setting. The pre-setting with the Plus and Premium variants can be modified on the luminaire in both mounted and dismantled state.

The LED Module 520 operates most efficiently with luminaires having a transparent enclosure:
Glare-free, directed light distribution via a precisely matched combination of high performance LEDs, either with warm white or neutral white light colour, optimal lens system with spreader, highly specular reflector and transparent luminaire cover:

• symmetric light distribution
• asymmetric light distribution without light spill to the rear
