Robust photovoltaic square lighting with LED lamp - no power connection required. High light intensity - the brightness is comparable to 2000 Watt halogen light. The lighting is switched on as required with a switch. Switching off is automatic after 1 or 2 hours via an adjustable timer. This way, switching off is not forgotten and the battery is not deep-discharged. The galvanised steel mast and the entire construction are so robust that kicking is pointless. The LED floodlight can be rotated and swivelled. All functions are pre-programmed by us free of charge according to project and customer specifications, so that the light is ready for operation immediately after assembly. The solar light is maintenance-free - (only the solar module should be cleaned with water occasionally). Technical specifications: Illuminated area: Aprx. 25 x 20m Ambient temperature: -20°C ~ +50°C (extension -35°C ~ +65°C possible on request) Protection class: III safety extra-low voltage Approval marks: CE, RoHS, WEEE 20-year availability guarantee for spare parts. Protection class luminaire control:IP67 Luminaire head specification: 2 robust LED luminaire heads made of die-cast aluminium The LED floodlights can be rotated and swiveled. LED lamp: SMD chipset LED power: 140W total Energy efficiency class B Light colour 4000K neutral white No UV radiation for reduced insect attraction LED efficiency: > 160 lm/w Luminaire efficiency: > 145 lm/w Luminous flux lumen: 20800 Lm Central illuminance: > 28 Lux LED life approx. 100,000 hours Protection class: IP66 (water and storm protected). Impact resistance: IK10 Warranty 5 years Solar module (without extension): Monocrystalline silicon 240W with very high efficiency (hardened protective glass, hailproof), approx. 25 years life expectancy. This high-quality module technology also guarantees charging in overcast conditions. All brackets and fixings are hot-dip galvanised (also available with a paint finish of your choice at an extra charge). The screws are made of VA stainless steel. Battery storage: Battery: lead-gel 12V maintenance-free, longlife, for solar cycle operation Service life approx. 5 - 10 years / 20°C Function even at low temperatures. For sufficient operating safety in autumn or winter, we strongly recommend our extension sets. Self-sufficient operating time in overcast weather (with fully charged battery): a) basic version: 6 hours b) with extension set autumn: 9 hours c) with extension set winter: 12 hours Temperature-optimised battery charging and trickle charging to protect the batteries. Overvoltage and deep discharge protection for battery. Reverse polarity and short circuit protection. Mast: Material: Steel pole, hot-dip galvanised Visible height: 8 m Ground section: 130 cm for setting in concrete (on request also 4m - 12m height) For easier erection, we also offer installation sleeves into which the mast can be inserted. Lockable mast door, for easy access to the control unit. Battery box: The batteries sit in the ground for protection against temperature fluctuations (longer life). Sturdy plastic box IP67 ( not walk-in version) with cable protection hose: Dimensions: L 496 x W 280 x H 270mm On request ABS box IP66 (walk-in version): Dimensions: L 550 x W 550 x H 480mm Delivery disassembled with the following components: Galvanised steel pole, 2 x LED lamp head with pole mounting, Solar module with stable, screwable pole mount, Microprocessor luminaire control unit (easily accessible behind a lockable door in the pole). Energy storage with floor installation box, Illustrated assembly instructions in German or English. Other languages on request. The ready-to-operate luminaire is delivered disassembled. All components are pre-wired and prepared for quick assembly.
