15 Watt | 24 Hours | Long Backup | Heavy Duty Body | IP65 Rating | Day & Night Sensor | Motion Sensor | 4500K Neutral Light – Solar Street Light

Overview

The 15W Solar Street Light (Lens Model 1186) is an all-in-one, off-grid outdoor lighting system designed for low-traffic residential streets, housing colony pathways, rural gram panchayat roads, farmhouse driveways, and parking lot perimeters across India. Featuring 108 Pcs 2W LED chips at a combined 200W output and a 3.2V 20Ah LiFePO4 battery, this unit delivers an exceptional 24 Hours of Long Backup per full charge cycle — making it suitable for year-round dusk-to-dawn operation across most Indian solar zones. Built into a Heavy Duty Body with IP65 weatherproofing, the 1186 combines a Day & Night Sensor for automatic dusk-to-dawn switching, a Motion Sensor for intelligent brightness management, and 4500K Neutral Light output through a precision 2-Lens optical design — delivering wide, uniform road illumination with no external wiring or grid connection required.

LED Performance & Light Output – 4500K Neutral Light

The 1186 model integrates 108 Pcs 2W LED chips delivering a combined 200W output in 4500K Neutral Light. The 4500K colour temperature sits between warm white and cool white, producing a natural, balanced light output that reduces eye strain on residential colony roads, school pathways, and pedestrian zones where human comfort matters alongside raw road visibility. The high LED count — 108 chips across a 2-lens optical array — ensures even distribution of light across the illuminated zone with reduced hotspot intensity, making this model particularly effective for narrow colony roads and residential street applications where glare control matters as much as brightness. The Lens Model optical system focuses light precisely onto the road surface, improving illumination efficiency over wide-angle flood configurations. The 24-hour Long Backup covers a full dusk-to-dawn cycle and beyond under typical Indian solar charging conditions.

Battery – LiFePO4 20Ah Capacity & 24-Hour Long Backup

The integrated 3.2V 20Ah LiFePO4 (Lithium Iron Phosphate) battery provides a robust energy reserve suited to the 200W LED draw of the 1186 model, delivering 24 hours of Long Backup — among the highest backup ratings available in the 15W solar street light segment in India. LiFePO4 chemistry is a significant upgrade over the lead-acid batteries commonly found in budget solar street lights at similar price points. Lead-acid cells lose capacity rapidly under repeated deep discharge, particularly during overcast monsoon periods in coastal Maharashtra, Kerala, and the north-east where several consecutive low-solar days can occur. LiFePO4 chemistry maintains over 80% capacity after 2,000 full charge-discharge cycles, providing more than five years of reliable daily operation without battery replacement. The chemistry is also thermally stable, making it safe for unattended installation in hot climates across Rajasthan, Gujarat, and Andhra Pradesh where summer temperatures frequently exceed 40°C.

Heavy Duty Body & Weatherproofing – IP65

The Lens Model 1186 is built into a Heavy Duty Body carrying an IP65 weatherproofing certification — confirming complete protection against dust ingress and resistance to water projected from any direction, the recommended minimum standard for outdoor lighting in India’s monsoon-affected climate. At 56 × 34 × 10 cm, the heavy duty housing is engineered to withstand the structural and environmental demands of installation at 5–7 metre pole heights, where wind load, UV exposure, coastal salt-air, and monsoon rainfall place greater stress on the light body than at lower residential mounting heights. Pole diameter compatibility is 55mm, compatible with standard Indian municipal streetlight poles as well as privately supplied GI poles widely used in housing society and colony road projects. The sealed heavy duty construction prevents moisture infiltration, dust accumulation, and insect ingress — the most common failure points in non-IP-rated solar street lights sold in the Indian market.

Smart Controls – Day & Night Sensor | Motion Sensor

The Lens Model 1186 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, providing consistent year-round coverage on colony roads and rural gram panchayat pathways where manual daily switching is not operationally feasible. 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 — ensuring efficient battery utilisation on low-traffic colony roads and rural pathways without compromising pedestrian safety. The included wireless remote control provides additional operational flexibility with OFF/ON (dusk-to-dawn switching), AUTO (motion sensor off, dusk-to-dawn), RADAR (motion sensor active, dusk-to-dawn), timed induction modes at 2H, 3H, and 4H, and a HALF LIGHT mode for 50% brightness operation — making the 1186 adaptable across a wide range of site conditions within a single product.

Solar Panel & Charging Efficiency

The 5V 26W monocrystalline solar panel integrated into the Lens Model 1186 is the highest-rated panel in its segment, providing the daily energy harvest required to replenish the 20Ah LiFePO4 battery within 6–8 hours of direct sunlight. Monocrystalline silicon cells achieve conversion rates of 19–23% under standard test conditions — significantly outperforming polycrystalline alternatives (13–17%) in both full-sun and diffused light conditions. The latter is particularly relevant during India’s June–September monsoon season when cloud cover reduces irradiance across coastal, north-eastern, and central India, and during the shorter, lower-angle solar days of north Indian winters (November–January). The factory-integrated panel angle removes on-site adjustment requirements, ensuring consistent charging performance across bulk installations managed by housing society maintenance teams and gram panchayat contractors without specialist solar knowledge.

Installation & Mounting

Installation of the Lens Model 1186 requires no external wiring, trenching, or grid connection. The all-in-one unit — solar panel, 20Ah LiFePO4 battery, LED module, Day & Night Sensor, Motion Sensor, and controller pre-assembled in the Heavy Duty Body at the factory — mounts to a 55mm diameter pole at 5–7 metres height using the included bracket. The 5–7 metre installation height is the highest in the residential-to-semi-commercial solar street light segment, enabling the 2-Lens optical array to cover wider road cross-sections and longer inter-pole spacings than lower-mounted alternatives. Total on-site work typically takes under 30 minutes per unit, making the 1186 particularly valuable for rural road lighting tenders, colony development projects, panchayat road improvement schemes, and farmhouse perimeter lighting where laying underground electrical cables is cost-prohibitive or technically infeasible. Supplied at 5 units per carton, logistics for bulk procurement by housing societies, municipal bodies, and contractors are straightforward.
