50W Solar Street Light – 18-24Hr Backup | 432 LED | IP65

Overview

The 50W Solar Street Light (High Power Model 1286, 8 Lens) is the highest-wattage variant in the standard LumenCity all-in-one solar street light range, designed for wide multi-lane housing society main roads, large township primary boulevards, panchayat district highways, industrial estate main access roads, large commercial parking areas, and farmhouse estate primary driveways across India. Featuring 432 Pcs 1W lens-type LED chips at a combined 450W output in cool white and a 3.2V 80Ah LiFePO4 battery providing 18–24 hours of illumination at installation heights of 10–15 metres, the High Power 1286 delivers the highest LED count, the highest combined output, and the largest battery capacity of any standard all-in-one unit in the LumenCity range. A 5V 80W monocrystalline panel — the largest in the range — IP65 weatherproofing, adjustable bracket, radar sensor, and wireless remote control complete the specification. The 10–15 metre installation height positions the 50W model at the boundary of residential-commercial and entry-level municipal road lighting, appropriate for wide roads of 8–14 metres cross-section.

LED Performance & Light Output

The High Power 1286 integrates 432 Pcs 1W lens-type LED chips — 33% more than the 38W model’s 324-chip array — at a combined 450W output in cool white across an 8 Lens optical configuration. The 8 Lens array produces the broadest beam pattern of the High Power series, appropriate for 10–15 metre mounting heights on wide multi-lane housing society roads, township primary boulevards, and district highway approaches where road widths of 8–14 metres require both high luminous intensity and wide angular coverage to achieve uniform road surface illuminance. Lens-type 1W chips are the appropriate LED format for the 10–15 metre height range: the precision optical lens on each chip concentrates output into a controlled beam that maintains acceptable ground-level illuminance at the greater mounting heights where SMD chip arrays would produce insufficient luminous intensity. At 450W combined cool white output from 432 lens chips, the High Power 1286 delivers the highest illuminance in the standard LumenCity all-in-one range and is the technically appropriate specification for the semi-municipal road lighting applications for which the 10–15 metre installation height is required.

Battery – LiFePO4 80Ah Capacity & Backup

The 3.2V 80Ah LiFePO4 battery in the High Power 1286 is 33% larger than the 38W model’s 60Ah unit, matching the higher 450W LED draw to deliver the same 18–24 hour backup specification at greater output — and representing the single largest LiFePO4 battery capacity in the standard LumenCity all-in-one range. At 80Ah, the LiFePO4 battery provides the most substantial monsoon-season energy reserve in the range, sustaining 18–24 hour operation through sensor-managed dimming even across consecutive overcast days in the high-rainfall coastal states of Kerala, Maharashtra, and the Western Ghats, and in the north-east monsoon zones of Assam, Meghalaya, and Tripura where charging failures are most common in under-specified solar street lights. Competing 50W all-in-one solar street lights on IndiaMart and Amazon.in at equivalent wattage typically specify 30–50Ah batteries; the High Power 1286’s 80Ah LiFePO4 specification is the primary specification differentiator for municipal procurement officers, housing society engineers, and township developers seeking the highest available backup duration at this wattage tier. LiFePO4 at 80Ah delivers 2,000+ cycles — over five years of daily operation — without the capacity degradation, sulphation, and maintenance demands of lead-acid alternatives.

Body Build & Weatherproofing

The High Power 1286 carries IP65 weatherproofing, certifying complete dust protection and water jet resistance across India’s full range of outdoor climate conditions. At 90.5 × 44.5 × 6.8 cm, the 50W High Power is 5 cm wider than the 38W model, accommodating the 432-chip 8 Lens LED array while maintaining the same 6.8 cm slim-depth profile that minimises aerodynamic loading at 10–15 metre pole heights. The 70mm pole specification is identical to the 38W model, enabling a unified pole standard for both High Power wattages within the same project — a logistics advantage confirmed for mixed-wattage housing society and township road lighting projects. The adjustable bracket enables LED housing angle adjustment independent of the pole arm, providing practical flexibility for the varied road geometries and kerb configurations encountered in large-scale township and district road lighting projects. At 10–15 metres, IP65 sealing is more critical than at lower heights — wind-driven rain, coastal salt spray, and dust exposure increase with mounting height, and the High Power 1286’s IP65 housing protects all internal electronics, the LED driver, and the 80Ah LiFePO4 battery across these conditions.

Smart Controls & Operating Modes

The High Power 1286 incorporates the same radar sensor and remote control system as the 38W model, with identical operating modes: OFF/ON, AUTO, Increase Brightness, Decrease Brightness, 3H, 5H, and 8H timed modes. At 450W LED output — the highest in the standard range — sensor management is most critical for the 18–24 hour battery performance claim. Without intelligent dimming, sustained 450W draw would deplete the 80Ah LiFePO4 battery in approximately 11 hours, covering only the shorter summer nights in India’s southern states and falling well short of the 14-hour winter nights in northern states. Sensor dimming at the 10%–100%–15% pattern reduces average consumption to approximately 60–100W on low-to-medium traffic township boulevards and district highways, enabling the 80Ah battery to achieve 18–24 hour operation under ideal conditions. The 8H timed mode — full brightness for 4 hours then off — is the recommended configuration for township main boulevard lighting where the 8–10 PM peak requires full 450W output and energy conservation through the night is required to sustain the 18–24 hour backup specification across India’s monsoon season.

Solar Panel & Charging Efficiency

The 5V 80W monocrystalline solar panel integrated into the High Power 1286 is the largest panel in the LumenCity all-in-one range, providing 23% greater peak output than the 38W model’s 65W panel. At 80W rated output, the monocrystalline panel harvests sufficient energy during 6–8 hours of direct sunlight to replenish the 80Ah LiFePO4 battery for the next night’s 18–24 hour operation cycle. Monocrystalline efficiency of 19–22% maintains reliable charging across India’s most demanding irradiance conditions — including the 90+ day Western Ghats and north-east monsoon season, the coastal overcast seasons of Tamil Nadu, Andhra Pradesh, and Odisha, and the short solar-day winters of Delhi, Punjab, and Uttar Pradesh where 10–15 metre solar street lights are most commonly specified for municipal road lighting tenders. For township developers and housing society management companies specifying the 50W High Power on primary boulevard and main road lighting, the 80W monocrystalline panel’s low annual output degradation — typically 0.3–0.5% per year — ensures consistent 18–24 hour backup performance across the 10–15 year project life typical of municipal-grade street lighting infrastructure. The adjustable bracket enables panel angle optimisation for the installation site’s specific latitude.

Installation & Mounting

The High Power 1286 installs without external wiring, underground cable, or grid connection. The fully pre-assembled unit mounts on a 70mm diameter pole at 10–15 metres height using the adjustable bracket. At 10–15 metres, the High Power 1286 bridges residential-commercial and entry-level municipal road lighting, covering the full range from wide township internal boulevards (10–11M) to district road approach lighting (12–15M) where no competing standard all-in-one solar street light at this wattage tier provides a confirmed comparable specification in the Indian market. The adjustable bracket provides LED housing angle flexibility for non-standard road geometries and pole arm orientations encountered in large township and district road projects. The 70mm pole specification matches the standard heavy-duty municipal GI poles used in Indian district road and national highway service road lighting tenders. The off-grid design eliminates the underground power cable civil works that represent 40–60% of the total per-pole cost in conventional municipal road lighting projects in India, making the 50W High Power model economically viable for panchayat district road schemes, industrial estate primary road lighting, and rural highway approach lighting under state and central government rural infrastructure funding programmes.
