24 Watt | 24 Hours | Long Backup | IP64 Rating | Day & Night Sensor | Motion Sensor | MPPT Fast Charging – Solar Street Light

Overview

The 24W Solar Street Light (King Model 1242) is an all-in-one, off-grid solar lighting system designed for housing colony main internal roads, housing society primary access streets, gated community boulevard lighting, rural panchayat main village roads, large parking lot perimeters, and farmhouse estate access roads across India. Featuring 610 Pcs 0.5W LED chips at a combined 300W output and a 3.2V 25Ah LiFePO4 battery providing 24 Hours of Long Backup at installation heights of 4–6 metres, the King Model 1242 delivers a lighting duration that far exceeds the 8–12 hour standard common among competing all-in-one solar street lights at equivalent wattage online. Built with IP64 weatherproofing, a Day & Night Sensor for automatic dusk-to-dawn switching, a Motion Sensor for intelligent brightness management, and MPPT Fast Charging technology for maximum daily solar harvest, the 1242 integrates all components into a single pre-assembled housing for no-wiring pole-top installation on 55mm diameter poles — with no external wiring or grid connection required.

LED Performance & Light Output

The King Model 1242 integrates 610 Pcs 0.5W LED chips at a combined 300W output in cool white. This chip count is among the highest available in the Indian all-in-one solar street light market at the 24W wattage tier, where competitors typically list 100–300 chip LED arrays. The 0.5W per chip distribution across 610 chips spreads thermal load uniformly across the LED board, reducing junction temperatures and maintaining lumen output over the LED array’s operational lifespan — a relevant consideration for unattended outdoor installations in India’s high-ambient-temperature regions across Rajasthan, Gujarat, Telangana, and Maharashtra. At 300W combined LED output in cool white, the 1242 delivers the road surface luminance appropriate for 4–6 metre mounting on medium-to-wide colony internal roads and housing society primary access streets where road widths of 5–8 metres require high-output, broadly distributed illumination for both pedestrian and slow-moving vehicle safety. The Day & Night Sensor ensures automatic activation at dusk and switch-off at dawn, and the Motion Sensor manages brightness intelligently to sustain the full 24-hour Long Backup across a complete dusk-to-dawn cycle.

Battery – LiFePO4 25Ah Capacity & 24-Hour Long Backup

The 3.2V 25Ah LiFePO4 battery in the King Model 1242 is the core enabler of its 24-hour Long Backup — a specification that directly addresses the most common complaint about competing solar street lights in India, where lights failing before dawn on housing society main roads and panchayat village roads are a recurring buyer issue. At 25Ah capacity, the LiFePO4 battery stores sufficient energy to power the 300W LED array — in conjunction with the Motion Sensor’s intelligent dimming and MPPT Fast Charging replenishment — across 24 hours of nightly operation under ideal sensor conditions. LiFePO4 (Lithium Iron Phosphate) at 25Ah maintains over 80% capacity across 2,000+ charge-discharge cycles — more than five years of daily operation — compared to the 300–500 cycle lifespan typical of lead-acid alternatives at comparable capacity. LiFePO4 also avoids the sulphation failure mode that affects lead-acid cells during partial-charge monsoon periods, and the thermal runaway risks of standard Li-ion chemistry in high-ambient-temperature Indian summer conditions — making it the correct chemistry for long-life common area and municipal road lighting installations.

Body Build & Weatherproofing – IP64

The King Model 1242 carries an IP64 weatherproofing certification, confirming complete dust ingress protection and resistance to directional water jets — the recommended minimum outdoor lighting standard for year-round deployment across India’s diverse climate conditions, from the heavy-rainfall zones of Kerala, the Western Ghats, and north-east India to the high-dust, high-UV semi-arid environments of Rajasthan, Gujarat, and western Madhya Pradesh. At 65 × 38.5 × 10 cm, the King Model 1242 has the widest flat-panel footprint in the standard all-in-one range at this wattage tier, accommodating the 610-chip LED array, 25Ah LiFePO4 battery, and MPPT Fast Charging controller within a sealed housing. The slim 10 cm depth maintains a low-profile aesthetic appropriate for the 4–6 metre residential-to-commercial installation height range, while the sealed construction protects all internal components from moisture infiltration, dust accumulation, and insect ingress across India’s full range of outdoor climate environments. Pole diameter compatibility is 55mm — the standard Indian municipal and semi-commercial solar street light pole diameter — enabling installation on existing GI pole infrastructure without bracket modification.

Smart Controls – Day & Night Sensor | Motion Sensor

The King Model 1242 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 housing society main roads and panchayat village road lighting 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. At 300W combined LED output, this sensor-managed dimming is critical for achieving the 24-hour Long Backup — without sensor management, continuous 300W draw would exhaust the 25Ah LiFePO4 battery in approximately 6 hours, well short of a full dusk-to-dawn cycle. Dimming reduces average nightly consumption to approximately 40–60W on low-to-medium traffic colony roads, enabling the 25Ah battery to achieve 24-hour operation under ideal conditions. The included wireless remote control provides additional flexibility with OFF/ON, AUTO, RADAR, and timed modes at 3H, 5H, 4+4H (4 hours full brightness followed by 4 hours induction), and 4+6H — the timed configuration being specifically relevant for housing society main road lighting where full brightness is required for the 6–10 PM peak period and reduced-mode operation is appropriate through the night.

MPPT Fast Charging – 5V 25W Monocrystalline Solar Panel

The King Model 1242 integrates MPPT (Maximum Power Point Tracking) Fast Charging technology with its 5V 25W monocrystalline solar panel — a significant charging efficiency advantage over the PWM (Pulse Width Modulation) controllers used in most competing solar street lights at this wattage. MPPT technology continuously tracks and locks onto the solar panel’s maximum power output point across changing irradiance conditions throughout the day, extracting up to 30% more usable charging energy from the same panel compared to PWM alternatives. This is particularly consequential for the 24-hour Long Backup claim — the 25Ah LiFePO4 battery must be fully replenished within the available daily solar window, and MPPT’s superior harvest efficiency ensures complete recharge within 6–8 hours of direct sunlight even during the reduced-irradiance conditions of India’s monsoon season and the shorter, lower-angle winter solar days of north India (November–January). Monocrystalline silicon cells achieve conversion efficiencies of 19–22% under standard test conditions, outperforming polycrystalline alternatives at equivalent panel surface area in both full-sun and diffused-light conditions — further maximising the daily energy harvest available to the MPPT controller. The factory-integrated panel orientation removes on-site tilt adjustment requirements for project-scale deployments.

Installation & Mounting

The King Model 1242 is designed for installation without external wiring, underground cable trenching, or grid connection. The fully pre-assembled unit — solar panel with MPPT Fast Charging controller, 25Ah LiFePO4 battery, 610-chip LED module, Day & Night Sensor, Motion Sensor, and wireless remote receiver — mounts on a 55mm diameter pole at 4–6 metres height using the included bracket. The 55mm pole specification is the most common diameter for residential colony and municipal solar street light poles in India, enabling the King Model to be installed on existing standard pole infrastructure without bracket modification. At 4–6 metres, the 1242 is positioned for colony main road lighting and housing society primary access road applications where maximum coverage at medium mounting height is the specification requirement. The off-grid design eliminates the civil works cost of underground power cable to each pole — the largest single cost component in conventional street lighting projects — making the King Model 1242 commercially viable for new township development primary road lighting, rural panchayat main road schemes, and housing society common area infrastructure upgrades. Supplied at 3 units per carton.
