25 Watt | 24 Hours | Long Backup | IP64 Rating | Day & Night Sensor | Motion Sensor | 160° Coverage – Solar Street Light

Overview

The 25W Solar Street Light (Aero Model 1185) is the highest-wattage variant in the Aero Design series, engineered for medium-width housing society main roads, large colony parking lots, rural district roads, industrial estate perimeter access roads, and highway service lanes across India. With 800 LED 5730 EPISTAR chips producing a combined 300W output and a 3.2V 30Ah LiFePO4 battery rated for an exceptional 24 Hours of Long Backup, the 1185 delivers the largest LED count and highest battery capacity in the Aero series. Built with IP64 weatherproofing, a Day & Night Sensor for automatic dusk-to-dawn switching, a Motion Sensor for intelligent brightness management, and a wide 160° Coverage beam pattern, the Aero Model 1185 operates as a fully self-contained off-grid unit at 6–8 metre installation height — making it the correct specification where wider road cross-sections and higher mounting heights demand greater output than the 20W Aero variant can deliver, with no external wiring or grid connection required.

LED Performance & Light Output – 160° Coverage

The Aero Model 1185 integrates 800 LED 5730 EPISTAR chips at a combined LED power output of 300W in cool white — 25% more chips and 20% more output than the 20W Aero variant — delivering a wide 160° Coverage beam pattern that maximises road surface illumination across the full carriageway width at the 6–8 metre installation height. The 160° beam spread ensures uniform ground-level coverage across medium-to-wide colony main roads, large housing society parking lots, and industrial estate perimeter tracks, reducing dark spots and inter-pole gaps that are common with narrower-beam competitors at equivalent mounting heights. EPISTAR 5730 chips are specified in the Aero series for their consistently high lumen output, long rated lifespan, and thermal reliability under the outdoor operating conditions encountered across India’s climate zones. The 800-chip array provides the extended illumination footprint required at 6–8 metres, where the wider 160° cone of light must cover broader road cross-sections and larger open areas than the 20W model’s installation height can achieve. Cool white output at 300W provides sharp contrast for both vehicle and pedestrian visibility, supporting road safety and perimeter security objectives at higher-traffic sites.

Battery – LiFePO4 30Ah Capacity & 24-Hour Long Backup

The 3.2V 30Ah LiFePO4 battery in the Aero Model 1185 provides 20% greater energy storage than the 25Ah unit in the 20W variant, proportionally matching the higher power draw of the 800-chip, 300W LED array to deliver 24 hours of Long Backup — among the highest backup ratings available in the 25W solar street light segment in India. This substantial energy reserve sustains multi-night illumination through Motion Sensor-managed dimming across low-to-medium traffic environments, and maintains backup performance through consecutive monsoon overcast days in coastal states, the north-east, and Western Ghats regions where 3–5 consecutive overcast days can prevent full daily charging. Compared to lead-acid battery solar street lights of equivalent wattage sold in India, the 1185’s LiFePO4 specification represents a superior total cost of ownership — fewer battery replacements over the installation life, lower maintenance interventions, and no risk of electrolyte leakage in the sealed all-in-one housing. LiFePO4 chemistry provides over 2,000 charge-discharge cycles at 80% depth of discharge, equating to more than five years of reliable daily operation before meaningful capacity degradation occurs.

Body Build & Weatherproofing – IP64

The Aero Model 1185 carries an IP64 weatherproofing certification, confirming complete dust ingress protection and resistance to directed water jets — the minimum recommended outdoor lighting standard for India’s monsoon climate, endorsed by procurement specifications for gram panchayat, municipal, and housing society road lighting projects. At 68 × 34.2 × 10 cm, the 25W housing is 8 cm longer than the 20W unit, accommodating the larger 800-chip LED array and 30Ah battery within the same slim 10 cm depth profile that minimises wind load across the full 160° Coverage arc at the 6–8 metre installation height. Pole diameter compatibility is 45mm — consistent with the 20W Aero variant — enabling mixed 20W and 25W deployments on a common pole specification, a significant logistical advantage for projects zoning different illumination levels across internal and main colony roads from a single pole supply. The sealed flat-panel Aero construction protects all internal electronics, the LiFePO4 battery, and the LED driver from moisture infiltration, thermal cycling, and dust accumulation across India’s full range of outdoor climate environments.

Smart Controls – Day & Night Sensor | Motion Sensor | 160° Coverage

The Aero Model 1185 operates fully automatically through two integrated sensing systems — a Day & Night Sensor and a Motion Sensor — ensuring hands-free dusk-to-dawn performance across the full 160° Coverage zone 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 industrial estate access tracks where manual daily switching is not operationally feasible. The Motion Sensor manages a three-state brightness sequence across the 160° detection arc: 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 LED output, this sensor-managed dimming is the critical enabler of the 24-hour Long Backup — without dimming, constant 300W draw would exhaust even the 30Ah LiFePO4 battery before completing a full overnight cycle. The dimming system reduces average power consumption to approximately 30–40% of rated output across a typical overnight cycle on medium-traffic roads, extending effective runtime well beyond the rated 24-hour figure in low-traffic conditions. The included wireless remote control provides additional flexibility with OFF, ALWAYS, INDUCTION, and timed induction modes at 2H, 4H, and 6H — the 4H and 6H modes providing the most energy-efficient configuration for housing society main roads and industrial estate access tracks where 300W output is needed during peak evening hours but can be reduced during the 2–5 AM low-activity window.

Solar Panel & Charging Efficiency

The 5V 34W monocrystalline solar panel in the Aero Model 1185 is the highest-rated panel in the Aero series, providing the daily harvest needed to replenish the 30Ah LiFePO4 battery within 6–8 hours of direct sunlight. At 34W, this monocrystalline panel generates approximately 17% more energy per day than the 29W panel in the 20W model, corresponding proportionally to the increase in battery capacity from 25Ah to 30Ah — ensuring the 24-hour Long Backup specification is achievable even under the reduced solar insolation conditions of north Indian winters (November–February) and the monsoon season (June–September nationwide). Monocrystalline efficiency of 19–22% ensures reliable charging performance during reduced-irradiance days when polycrystalline-equipped competitors are more likely to under-charge and fail to deliver claimed backup durations. The factory-integrated panel angle ensures consistent performance across bulk deployments without site-level calibration, and the sealed panel-housing interface prevents moisture ingress at the junction.

Installation & Mounting

The Aero Model 1185 installs without external wiring, trenching, conduit work, or grid connection. The fully pre-assembled unit — solar panel, 30Ah LiFePO4 battery, LED module, Day & Night Sensor, Motion Sensor, and controller — is bracket-mounted to a 45mm diameter pole at 6–8 metres height using the included bracket, positioning the 160° Coverage beam at the optimal height for uniform road surface illumination across medium-to-wide colony main roads and large open areas. At 6–8 metres, the 1185 targets road widths and open areas where pole heights below 6 metres would fail to achieve the required illuminance uniformity across the full carriageway. The off-grid design is directly relevant to the primary market for this wattage in India — new housing development main road lighting where grid infrastructure is delayed, rural district road improvement schemes, industrial estate road lighting, and large farmhouse or plantation main access road lighting. Supplied at 3 units per carton, reflecting the larger unit size, the 1185 is procurement-ready for project-scale buying by civil contractors, housing developers, and gram panchayat and municipal bodies.
