The SQ luminaires with three construction sizes (SQ 50, SQ 100 and SQ 200) represent a flexible luminaire family for the technical road lighting sector. The three variants enable the design of a uniform, overall road appearance with the simultaneous solving of many varied lighting tasks. All SQ luminaires feature high quality workmanship with diecast aluminium and an elegant appearance. The functional luminaire form is designed to minimise the effects of wind. Equipped with state-of-the-art lighting technology and precise optics, the luminaires offer outstanding solutions in relation to energy efficiency, luminaire spacing and light quality. Various optical covers (flat/convex cover or enclosure) and various lamp configurations set a wide variety of road situations in the right light. If the luminaire is equipped with a module for instant hot re-ignition then special security and monitoring applications are possible.
Despite their robust construction and high (IP66) protection rating, the SQ luminaires are easy to handle: by pulling the lever catch the luminaire cover is opened upwards. The mechanism cuts off the power supply; maintenance and control work as well as gear tray replacement can be carried out without danger. The variability of the efficient radial facetted reflector is also practical, the reflector optimally splitting the light point for wide asymmetric glare-free light.

• future-fit Vario gear tray technology
• individually settable optics via radial facetted reflector (for T and E lamps)
• high luminaire light output ratios
• electrical unit replaced without tools
• convenient one-hand lever catch
• universal fixing system via pivotable mast clamping plate

Two-part luminaire housing consisting of frame and canopy (can be opened upwards) | frame, mast clamping plate, canopy and easy-access one-hand lever catch of diecast aluminium with extremely weather-resistant coating: frame metallic grey (RAL 9006), canopy aluminium grey (RAL 9007) | all-round bi-component EPDM sealing with labyrinth function | luminaire cover either flat cover of toughened safety glass or diffuser of PMMA or PC | pivotable mast clamping plate flush-integrated in frame, for post-top and side-entry mounting; 0° inclination with post-top mounting, with offset mast spigot with side-entry mounting | pressure equalisation system with air-permeable membrane for condensation avoidance in the housing | insulation class: II | protection rating: IP66 for complete luminaire (dustproof and water-jet proof)

Canopy opened without tools, can be folded upwards; with automatic all-pole power disconnection | tool-free relamping | all electric components mounted on removable gear tray; connection via plug-in coupling | luminaire wired ready for connection, with 2-pole terminal, max. 2.5mm² (version with reducing circuit: 2-pole + 1-pole for 230V control wire, max. 1.5mm²) | optionally with efficient electronic control gear (ECG) and Street Light Control (SLC) lighting management components (SLC: central control and monitoring of intelligent light points) or with LLCG with parallel p.f. correction | special versions also available with power factor-corrected LLCG and ignition device for instant hot re-ignition | power reduction: U_St= 230V --> 100% luminous flux; U_St= 0V --> 50% luminous flux (with start in power reduction mode: 100% mode initially for approx. 6mins.)

Wide light distribution and high uniformity due to highly efficient radial facetted optics | variable light-band deflection via adjustable optics | high level of system efficiency in watt ratings to 400W with system-optimised light distribution and wide luminaire spacing | optical enclosure is either flat cover panel of toughened safety glass for minimised light immission, or transparent enclosure (PMMA)
