Overview The 3W Solar Street Light (Double Body Model 1117, 1 Window) is the smallest and most compact unit in the Double Body series, designed for narrow residential colony footpaths, housing society garden boundary walls, gated community internal pedestrian alleys, farmhouse garden perimeters, and rural village access lanes across India. Featuring 80 LED 5730 EPISTAR chips producing a combined 30W output in cool white and a 3.2V 6Ah LiFePO4 battery rated for 12 hours of illumination, the 1117 operates at 3-metre pole height — the lowest in the Double Body series — making it ideal for low-clearance residential environments. Fully automatic operation is delivered through an integrated Day & Night Sensor and Motion Sensor, with IP65 weatherproofing ensuring year-round reliability across all Indian climate zones — no grid connection or external wiring required. LED Performance & Light Output The Double Body 1117 integrates 80 LED 5730 EPISTAR chips at a combined output of 30W in cool white. The EPISTAR 5730 chip is a professional-grade SMD LED used across the Double Body, Aero, and Aero Plus series for its consistent lumen output and long operational lifespan — a recognised quality benchmark in online search categories for solar street lights. At 80 chips in a 1 Window array, the 1117 produces focused, uniform cool white light well suited to narrow footpaths, garden walls, and colony alley applications where coverage width is limited. The cool white colour temperature provides adequate contrast for pedestrian safety on residential colony footpaths and housing society garden paths without producing the glare associated with higher-chip-count arrays at equivalent mounting heights. Battery – LiFePO4 6Ah Capacity & 12-Hour Backup The 3.2V 6Ah LiFePO4 battery in the Double Body 1117 stores sufficient energy to power the 30W LED array through 12 hours of dusk-to-dawn operation under ideal sensor conditions. LiFePO4 (Lithium Iron Phosphate) chemistry is a significantly superior specification to the lead-acid or standard Li-ion batteries found in many competing sub-5W solar lights available at similar price points online. Lead-acid batteries in this energy range typically provide 300–500 cycles before meaningful capacity loss, while LiFePO4 maintains over 80% capacity at 2,000 cycles — equivalent to more than five years of daily dusk-to-dawn operation. LiFePO4’s thermal stability is also a practical safety benefit in unattended installations, particularly in compact-format solar lights operating in the high-ambient temperatures of Indian summers. Body Build & Weatherproofing The Double Body Model 1117 carries an IP65 weatherproofing rating, certifying complete dust ingress protection and resistance to water jets from any direction. IP65 exceeds the standard IP64 minimum for outdoor lighting, making the 1117 particularly well suited for year-round deployment across India’s most demanding climate zones — from the heavy-rainfall Western Ghats and Kerala coastal belt to the high-dust semi-arid zones of Rajasthan and western UP. At 25 × 30 × 10 cm, the 1117 is the most compact unit in the Double Body series, with a slim 10 cm depth that minimises wall-bracket projection and visual imbalance at the 3-metre installation height. The 40mm pole diameter compatibility covers smaller residential GI poles commonly used in Indian housing society garden and pathway lighting projects. The sealed Double Body housing protects all internal electronics, LED driver, and LiFePO4 battery from moisture, dust, and insect ingress. Smart Controls & Sensor Operation The Double Body 1117 operates fully automatically through two integrated sensing systems — a Day & Night Sensor and a Motion Sensor — ensuring hands-free dusk-to-dawn performance without any manual switching. The Day & Night Sensor activates the unit automatically at dusk and switches it off at dawn across all seasons. The Motion Sensor manages a three-state brightness sequence: 10% standby brightness during inactive periods, 100% full brightness on motion detection, and 15% brightness for 30 seconds post-motion before returning to standby. This sensor-managed dimming is critical to achieving the 12-hour backup at 30W output — without dimming, sustained full output would exhaust the 6Ah battery in approximately 6–7 hours. The motion sensor mode is particularly suited to residential garden paths and colony footpaths where activity is concentrated in the early evening and overnight full-brightness illumination is neither required nor desirable for adjacent sleeping residents. Solar Panel & Charging Efficiency The 5V 3W monocrystalline solar panel integrated into the Double Body 1117 charges the 6Ah LiFePO4 battery within 6–8 hours of direct sunlight. Monocrystalline silicon cells achieve conversion efficiencies of 19–22% under standard test conditions, outperforming polycrystalline alternatives at both full irradiance and diffused light levels — relevant during India’s June–September monsoon season when competing polycrystalline-equipped units may fail to fully charge overnight capacity. The 3W panel is correctly sized for the 6Ah battery’s daily energy requirement under average Indian solar conditions, ensuring reliable 12-hour backup across all 12 months of the solar year in most Indian states. The factory-integrated panel eliminates on-site tilt calibration for residential installations. Installation & Mounting The Double Body 1117 is designed for no-wiring installation. The fully pre-assembled unit — with Day & Night Sensor and Motion Sensor factory-integrated — mounts to a 40mm diameter pole at 3 metres height using the included bracket, with no electrical connections to the grid required. At 3 metres, the unit is appropriate for residential colony footpaths, garden boundary walls, and gated community internal alleys where higher pole heights would visually dominate low-density housing environments. Installation is typically completed in under 20 minutes per unit and does not require specialist solar installation experience, making the 1117 practical for housing society maintenance staff. At 10 units per carton, logistics for bulk colony and society scheme procurement are efficient.
