Here is the updated product description aligned with the title: Overview The 22W Solar Street Light (Lens Model 1187) is an all-in-one, off-grid outdoor lighting solution designed for medium-width colony roads, housing society main entrances, large parking lots, rural district roads, highway service lanes, and industrial estate access roads across India. With 162 Pcs 2W LED chips producing a combined 250W output in 4500K Neutral Light and a 3.2V 30Ah LiFePO4 battery, the 1187 delivers 24 Hours of Long Backup per charge cycle at installation heights of 7–10 metres. Built into a Heavy Duty Body with IP65 weatherproofing, the Lens Model 1187 combines a Day & Night Sensor for automatic dusk-to-dawn switching and a Motion Sensor for intelligent brightness management — with a 3-lens optical configuration providing an extended beam spread across wider road cross-sections and higher-mounting applications than the 15W model. A wireless remote control is included as standard, with no external wiring or grid connection required. LED Performance & Light Output – 4500K Neutral Light The 22W Lens Model 1187 integrates 162 Pcs 2W LED chips at a combined 250W output in 4500K Neutral Light, deployed across a 3-lens optical array. The 4500K colour temperature delivers a natural, balanced light output that sits between warm white and cool white — reducing eye strain on colony main roads, housing society entrance roads, and industrial estate access lanes where human comfort and visibility must both be optimised across extended dusk-to-dawn operating periods. The 162-chip configuration provides 50% greater LED count than the 15W variant, supporting the broader illumination footprint required at 7–10 metre installation heights on medium-to-wide roads. The 3-lens optical distribution system achieves a batwing-type beam pattern, directing 4500K Neutral Light laterally across the road surface and minimising spill above the horizontal plane — improving lumen utilisation, reducing sky glow, and ensuring compliance with road illuminance standards required by municipal and housing society procurement bodies in India. The Day & Night Sensor ensures automatic activation at dusk and switch-off at dawn, with the Motion Sensor managing brightness intelligently to sustain 24-hour Long Backup performance across a full dusk-to-dawn cycle. Battery – LiFePO4 30Ah Capacity & 24-Hour Long Backup The 3.2V 30Ah LiFePO4 battery in the Lens Model 1187 provides 50% greater storage capacity than the 20Ah unit in the 15W model, supporting the higher power draw of the 162-chip LED array across 24 hours of Long Backup — among the highest backup ratings available in the 22W solar street light segment in India. This larger capacity also provides a meaningful buffer against consecutive low-solar days during the monsoon season, particularly relevant for deployments in the north-east, Odisha coast, and Western Ghats regions where extended overcast periods are common. LiFePO4 chemistry is fundamentally superior to both lead-acid and standard Li-ion alternatives in the solar street light segment — lead-acid batteries degrade rapidly under the deep daily discharge cycles inherent to dusk-to-dawn solar lighting, while standard Li-ion cells present thermal management risks in high-ambient-temperature Indian summer conditions that LiFePO4 avoids by design. LiFePO4 maintains over 80% capacity after 2,000 charge-discharge cycles, equating to more than five years of reliable daily operation without battery replacement. Heavy Duty Body & Weatherproofing – IP65 The Lens Model 1187 is built into a Heavy Duty Body carrying an IP65 weatherproofing rating — confirming complete protection against dust ingress and resistance to directed water jets, essential for year-round outdoor operation across India’s diverse climate zones including monsoon-heavy coastal areas, dusty semi-arid regions, and high-humidity agricultural zones. At 71 × 35.5 × 11 cm, the heavy duty housing is engineered to withstand the structural and environmental demands of installation at 7–10 metre pole heights — the highest installation range in the Lens Model series — where wind load, UV exposure, coastal salt-air, and monsoon rainfall place the greatest stress on the light body. The robust construction accommodates the increased 162-chip LED array and 30Ah LiFePO4 battery within a sealed housing that prevents the dust infiltration and pest ingress that commonly cause premature failure in non-IP-rated units at lower price points. Pole compatibility is 55mm diameter — identical to the 15W model — enabling mixed deployments of both wattages on a common pole specification and simplifying procurement for multi-zone projects. Smart Controls – Day & Night Sensor | Motion Sensor The Lens Model 1187 operates fully automatically through two integrated sensing systems — a Day & Night Sensor and a Motion Sensor — ensuring hands-free dusk-to-dawn performance in 4500K Neutral Light 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 main roads, large parking lots, and industrial estate access lanes 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 radar motion detection, and 15% brightness for 30 seconds post-motion before returning to standby. This intelligent dimming is critical for the 30Ah battery to sustain the 24-hour Long Backup across low-traffic overnight periods on colony main roads and industrial estate perimeters — without sensor-managed dimming, the sustained 250W draw would significantly reduce operational duration below the 24-hour rating. The included wireless remote control provides additional flexibility with AUTO, RADAR, timed induction modes at 2H, 3H, and 4H, HALF LIGHT (50%), and FULL LIGHT — allowing project managers and society maintenance teams to optimise energy use per zone without requiring physical access to each unit. The RADAR mode combined with the 3-lens 250W output and 4500K Neutral Light makes the 1187 particularly effective for large parking lots, logistics yard perimeters, and rural petrol station forecourts. Solar Panel & Charging Efficiency The 5V 36W monocrystalline solar panel in the Lens Model 1187 is 38% larger in peak wattage than the 26W panel in the 15W model, providing the additional daily energy harvest needed to replenish the 30Ah LiFePO4 battery within 6–8 hours of direct sunlight. Monocrystalline panel efficiency of 19–23% ensures the 1187 remains fully functional during the reduced irradiance conditions of India’s monsoon months, outperforming polycrystalline-equipped competing products that are more sensitive to cloud cover and diffused light — relevant across the Western Ghats, north-eastern states, and Odisha coast where extended overcast periods are most frequent. The panel is factory-integrated into the Heavy Duty Body at an optimal fixed angle, removing the need for site-level tilt calibration across large installation volumes and ensuring repeatable charging performance across geographically dispersed project sites. Installation & Mounting The Lens Model 1187 is designed for no-wiring, off-grid installation. The pre-assembled unit — solar panel, 30Ah LiFePO4 battery, 162-chip LED module, Day & Night Sensor, Motion Sensor, and controller, all sealed within the Heavy Duty Body — is bracket-mounted onto a 55mm pole at 7–10 metres height with no electrical connections required. The 7–10 metre installation height is the highest in the residential-to-commercial solar street light segment, positioning the 3-lens 250W, 4500K Neutral Light output at the optimal height for uniform road surface illumination across medium-to-wide colony main roads, large parking areas, and industrial estate access lanes. The off-grid design is directly relevant to the most common procurement use cases in India — peri-urban housing developments, gram panchayat rural road schemes, industrial estate perimeter roads, and large farmhouse driveways where grid power availability or cost makes wired lighting infeasible. The 55mm pole compatibility shared with the 15W model simplifies supply chain management for projects using both wattages across different zones. Supplied at 3 units per carton, the 22W Lens Model is packaged for project-scale procurement by housing developers, civil contractors, and municipal bodies.
