3W Solar Street Light – EPISTAR LED | IP65 | Dusk to Dawn

 

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 8–12 hours (1 night) of illumination under ideal sensor conditions, the 1117 operates at 3-metre pole height — the lowest in the Double Body series — making it ideal for low-clearance residential environments where higher-wattage units would be structurally over-specified. The Double Body design integrates the solar panel, battery, LED module, radar sensor, and remote controller into a single sealed housing with no grid connection 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 — it is a recognised quality benchmark on both Amazon.in and IndiaMart 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 & Backup

The 3.2V 6Ah LiFePO4 battery in the Double Body 1117 stores sufficient energy to power the 30W LED array through 8–12 hours of 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 on Amazon.in and IndiaMart. 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. At the 3W wattage tier, LiFePO4’s thermal stability is also relevant: batteries in low-wattage, compact-format solar lights are closer to the solar panel’s thermal output, making thermal runaway resistance in the LiFePO4 chemistry a practical safety benefit in unattended installations.

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 is the minimum recommended outdoor lighting standard for deployment across India’s monsoon-affected 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 & Operating Modes

The Double Body 1117 features a radar-based motion sensor and wireless remote control enabling the same operating mode set as all other Double Body variants: OFF (full dusk-to-dawn switch-off), ALWAYS (motion sensor disabled, constant illumination), INDUCTION (full radar-active dusk-to-dawn), and timed induction modes at 2H, 4H, and 6H. The sensor activates at 10% optical brightness initially, triggers 100% on motion detection, and holds at 15% for 30 seconds after motion ceases. This three-state dimming is critical for achieving the 8–12 hour battery runtime at 30W output — without dimming, sustained full output would exhaust the 6Ah battery in approximately 6–7 hours. The 2H and 4H induction modes suit residential garden paths and colony footpaths where activity is concentrated in the early evening (6–10 PM) and overnight illumination at full brightness is unnecessary 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 — the latter being 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 1-night 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 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 and direct light onto adjacent properties. 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 procurement. At 10 units per carton, logistics for bulk colony and society scheme procurement are efficient.
