28W Solar Street Light – 18-24Hr Backup | 576 LED | IP65

Overview

The 28W Solar Street Light (Apple Model 1269) is an all-in-one, off-grid solar lighting system designed for housing colony main internal roads, large housing society compound perimeters, gated community primary access roads, rural district highways, industrial estate entrance roads, and farmhouse primary driveways across India. Featuring 576 Pcs 0.5W LED chips at a combined 300W output in cool white and a 3.2V 42Ah LiFePO4 battery providing 18–24 hours of illumination at an installation height of 5–7 metres, the Apple Model 1269 delivers the longest stated backup duration in the LumenCity lineup and one of the highest LED counts available at this wattage tier in the Indian all-in-one solar street light market. A 5V 40W monocrystalline solar panel, IP65 weatherproofing, radar motion sensor, and wireless remote control complete the specification. Pole diameter is not specified — the bracket system accommodates standard Indian solar street light pole dimensions.

LED Performance & Light Output

The Apple Model 1269 integrates 576 Pcs 0.5W LED chips at a combined 300W output in cool white. This chip count is substantially higher than the LED arrays found in competing 28W all-in-one solar street lights at equivalent wattage on Amazon.in and IndiaMart, where 100–200 chip counts are standard. The 0.5W per chip format distributes heat across a larger LED board surface, reducing junction temperature and improving long-term lumen maintenance compared to fewer, higher-wattage individual chips that concentrate thermal load in smaller areas. At 300W combined LED output in cool white, the 1269 delivers the brightness appropriate for housing society main road lighting, colony access street illumination, and rural district highway approach road lighting at 5–7 metre mounting height, where road widths of 5–8 metres require high-output, wide-angle illumination for both vehicle and pedestrian safety.

Battery – LiFePO4 42Ah Capacity & Backup

The 3.2V 42Ah LiFePO4 battery in the Apple Model 1269 is the largest battery capacity in the standard LumenCity all-in-one solar street light range and enables the 18–24 hour lighting duration specification that sets this model apart from all other products in the Indian solar street light market at comparable wattage. At 42Ah, the LiFePO4 battery stores sufficient energy to sustain the 300W LED array — in conjunction with the radar sensor’s intelligent dimming — across 18–24 hours of nightly operation under ideal conditions. This is a direct competitive advantage over the majority of 28W solar street lights on Amazon.in and IndiaMart that specify 8–12 hour backup at the same wattage: the 42Ah battery provides a reserve that covers India’s longest winter nights (up to 14 hours in northern states) and maintains meaningful illumination even on consecutive overcast monsoon days when the 40W monocrystalline panel cannot achieve a full recharge. LiFePO4 chemistry at 42Ah delivers 2,000+ charge-discharge cycles — more than five years of daily operation — compared to 300–500 cycles for lead-acid alternatives at equivalent capacity, which is decisive for long-term total cost of ownership in housing society and municipal road lighting applications.

Body Build & Weatherproofing

The Apple Model 1269 carries an IP65 weatherproofing certification, confirming complete dust ingress protection and resistance to water jets from any direction. IP65 is the recommended minimum standard for outdoor lighting deployed year-round in India, covering the high-rainfall coastal belts of Kerala, Maharashtra, and Tamil Nadu; the heavy monsoon zones of the Western Ghats and north-east India; and the high-dust, high-UV conditions of Rajasthan, Gujarat, and the Deccan plateau. At 51 × 39 × 10 cm, the Apple Model 1269 has the widest LED panel footprint in the standard LumenCity all-in-one range, reflecting the 576-chip array housed within the flat-panel Apple Model body design. The 10 cm depth is consistent with the flat-panel aesthetic that distinguishes the Apple Model series from the more compact lens and Aero series. The sealed housing protects the LED array, driver circuitry, and 42Ah LiFePO4 battery from all ambient conditions encountered in Indian outdoor deployment.

Smart Controls & Operating Modes

The Apple Model 1269 is equipped with a radar motion sensor and a wireless remote control providing the full operating mode set. The sensor operates at 10% optical brightness initially, activates to 100% brightness on motion detection, and holds at 15% brightness for 30 seconds after motion ceases. This three-state dimming sequence is fundamental to achieving the 18–24 hour battery runtime at 300W LED output — without sensor-managed dimming, constant 300W draw would exhaust the 42Ah LiFePO4 battery in approximately 9–10 hours, falling well short of the extended backup specification. Dimming reduces average nightly consumption to approximately 40–60W on low-to-medium traffic colony roads and district highways, enabling the 42Ah battery to achieve the 18–24 hour specification under ideal conditions. Remote control operating modes include OFF/ON (full dusk-to-dawn switch), Motion Sensor mode (dusk-to-dawn with radar), Auto mode (motion sensor auto), and timed modes at 2H, 3H, and 4H as shown on the remote image. The full mode set enables housing society management committees and municipal contractors to configure each unit for its specific traffic pattern without physical on-site access.

Solar Panel & Charging Efficiency

The 5V 40W monocrystalline solar panel integrated into the Apple Model 1269 is the largest panel in the standard LumenCity all-in-one range, providing the daily energy harvest required to replenish the 42Ah LiFePO4 battery within the 6–8 hour charging window. At 40W rated output, the monocrystalline panel achieves conversion efficiencies of 19–22% under standard test conditions — significantly higher than polycrystalline alternatives at the same panel surface area. This efficiency advantage is most relevant during India’s monsoon season (June–September) when diffused irradiance conditions reduce panel output, and during the shorter solar days of north Indian winters (November–January) when panel output is further reduced by lower sun angles. For large housing society and municipal projects where the 28W Apple Model is deployed across multiple poles, the 40W monocrystalline panel’s superior low-light performance reduces the frequency of under-charged batteries and consequent early-night lighting failures — a reliability consideration that directly affects resident satisfaction in housing society common area lighting. The factory-integrated panel angle ensures consistent orientation across bulk project installations without site-specific calibration.

Installation & Mounting

The Apple Model 1269 is designed for installation without external electrical wiring, underground cable trenching, or grid connection. The fully pre-assembled unit mounts on a standard solar street light pole at 5–7 metres height using the standard bracket system. No pole diameter is specified in the product image; the bracket accommodates standard Indian solar street light poles in the 40–60mm range. At 5–7 metres, the Apple Model 1269 is positioned for colony main road lighting and housing society access road applications where maximum coverage width is required and higher mounting heights are standard for municipal-grade lighting infrastructure. The off-grid design eliminates the civil works cost of underground power cable installation — typically the largest single cost component in conventional street lighting projects in India — making the Apple Model 1269 commercially viable for rural district road lighting, panchayat main road schemes, and new housing society township development where grid extension costs are prohibitive. Supplied at 4 units per carton.
