25W Solar Street Light – 2 Night Backup | EPISTAR LED | IP65

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 in cool white and a 3.2V 30Ah LiFePO4 battery rated for 2 nights of continuous illumination, the 1185 delivers the largest LED count and highest battery capacity in the Aero series. The 6–8 metre installation height range makes this model the appropriate choice where the 20W Aero’s 5–7 metre height range is insufficient, or where a wider road cross-section requires additional pole height to achieve the required illuminance level across the full carriageway width.

LED Performance & Light Output

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. 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 the 6–8 metre installation height, where a wider cone of light must cover broader road cross-sections and larger open areas such as colony main roads, housing society parking lots, and industrial estate perimeter tracks. As with the 20W model, cool white light output at 300W provides sharp contrast for both vehicle headlight interaction and pedestrian visibility, supporting both road safety and perimeter security objectives at higher-traffic sites.

Battery – LiFePO4 30Ah Capacity & 2-Night 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 the same 2-night backup performance. A 30Ah LiFePO4 battery at this discharge rate provides the additional reserve capacity that sustains illumination continuity during periods of reduced solar input — a meaningful advantage during India’s monsoon season, when coastal states, the north-east, and Western Ghats regions can experience 3–5 consecutive overcast days that prevent full battery replenishment. 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.

Body Build & Weatherproofing

The Aero Model 1185 carries the same IP65 weatherproofing certification as the 20W model, confirming complete dust and directional water protection across all outdoor Indian deployment environments. At 68 × 34.2 × 10 cm, the 25W housing is 8 cm longer than the 20W unit, accommodating the larger LED array and 30Ah battery within the same slim 10 cm depth profile. Pole diameter compatibility remains 45mm across both Aero wattages, 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 same flat-panel profile and sealed construction that characterises the Aero Design series minimises wind load at 6–8 metre height and protects internal components from the dust, moisture, and thermal cycling inherent in unattended outdoor operation across India.

Smart Controls & Operating Modes

The Aero Model 1185 incorporates the identical radar sensor and remote control system as the 20W variant, with the same operational mode set: OFF, ALWAYS, INDUCTION, and 2H, 4H, and 6H timed induction. The sensor’s 10% startup, 100% active, and 15% post-motion dimming logic is even more critical at 300W LED output — without sensor-based power management, constant 300W draw would exhaust even the 30Ah LiFePO4 battery before achieving 2 nights of operation. The intelligent 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 2-night figure in low-traffic conditions. For housing society main roads and industrial estate access tracks — where 300W output is needed during peak hours but can be reduced during the 2–5 AM low-activity window — the 4H and 6H induction modes provide the most energy-efficient configuration.

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 the standard 6–8 hour charging window. At 34W, this monocrystalline panel generates approximately 17% more energy per day than the 29W panel in the 20W model, corresponding to the proportional increase in battery capacity from 25Ah to 30Ah. Monocrystalline efficiency at 19–22% ensures reliable charging performance during the reduced-irradiance days of India’s winter (November–February in the north) and monsoon (June–September nationwide), 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 shares the same no-wiring, off-grid installation process as the 20W variant. The pre-assembled unit mounts to a 45mm diameter pole at 6–8 metres height using the included bracket, with no electrical connections required. At 6–8 metres, the 1185 targets medium-to-wide roads and large open areas where pole heights below 6 metres would fail to achieve the required illuminance uniformity across the full road width. The off-grid design is directly relevant to the primary market for this wattage range in India: new housing development main road lighting where grid infrastructure is delayed, rural district road improvement schemes, industrial estate road lighting where connection to the factory power supply is commercially undesirable, 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.
