Overview
The 25W Solar Street Light (Aero Plus Model 1347) is an all-in-one, off-grid outdoor lighting system designed for housing colony roads, residential society parking lots, rural gram panchayat pathways, farmhouse driveways, and low-to-medium traffic suburban streets across India. Equipped with 576 LED 5730 chips delivering a combined 200W output and a 3.2V 20Ah LiFePO4 battery rated for 2 nights of illumination, this unit is one of the few products in its wattage segment to offer multi-night backup capability — a critical differentiator confirmed by buyer search patterns on Amazon.in and IndiaMart. The Aero Plus body design integrates the solar panel, battery, LED module, radar sensor, and wireless controller into a single compact unit at installation heights of 4 to 5 metres, with no external wiring or grid connection required.
LED Performance & Light Output
The Aero Plus 1347 integrates 576 LED 5730 chips at a combined 200W output in cool white light. LED 5730 chips are a professional-grade SMD LED variant widely specified in commercial outdoor lighting for their superior lumen efficacy and thermal performance compared to standard 5050 or 3030 chips. The high chip count — 576 individual 5730 LEDs — ensures a very even light distribution with low localised intensity, reducing glare on residential streets and colony pathways where pedestrians are the primary user. Cool white output maximises contrast and visibility for both foot traffic and slow-moving vehicles. The 2-night lighting capability is driven by the combination of high-efficiency LEDs and intelligent radar-based dimming that reduces power draw during no-motion periods, extending battery runtime significantly beyond a single-night cycle.
Battery – LiFePO4 20Ah Capacity & 2-Night Backup
The 3.2V 20Ah LiFePO4 battery in the Aero Plus 1347 is the primary enabler of its 2-night backup rating — a performance level that is markedly superior to the single-night backup offered by most lead-acid or Li-ion solar street lights sold in the Indian market at comparable price points. LiFePO4 (Lithium Iron Phosphate) chemistry offers over 2,000 charge-discharge cycles at 80% depth of discharge, translating to more than five years of reliable daily operation without capacity degradation. Unlike lead-acid batteries, LiFePO4 cells do not suffer from sulphation during partial-charge states, which commonly occurs during India’s monsoon months when consecutive overcast days reduce solar input. The chemistry is also thermally stable at the high ambient temperatures prevalent in Rajasthan, Gujarat, Telangana, and other hot-climate Indian states, unlike standard Li-ion cells that can present thermal risks above 45 degrees Celsius.
Body Build & Weatherproofing
The Aero Plus Model 1347 carries an IP65 weatherproofing certification, confirming complete protection against dust ingress and resistance to water jets from any direction. IP65 is the standard minimum for outdoor lighting in India’s monsoon-affected climate, making this unit suitable for year-round unattended operation across coastal, semi-arid, and high-humidity agricultural regions. The compact body dimensions of 42 × 35 × 9 cm make the Aero Plus one of the more compact units available for 25W output in the Indian market, reducing wind load at the 4–5 metre installation height. Pole compatibility is 45mm diameter, which is compatible with standard GI poles widely used in Indian housing society and gram panchayat road projects. The sealed housing construction prevents moisture infiltration, dust accumulation, and insect ingress — common failure causes in non-IP-rated solar lights available at lower price points.
Smart Controls & Operating Modes
The 1347 includes a radar-based motion sensor and a wireless remote control providing multiple operating modes. The sensor activates at 10% optical brightness initially, triggers 100% brightness on motion detection, then holds at 15% brightness for 30 seconds post-motion before returning to standby — a pattern that maximises battery autonomy across the 2-night operational window on low-traffic colony roads and rural village pathways. Remote control modes include OFF (full dusk-to-dawn switch off), ALWAYS (motion sensor off, constant dusk-to-dawn illumination), INDUCTION (full radar-active dusk-to-dawn), and timed induction modes at 2H, 4H, and 6H intervals after which the unit enters a reduced-brightness or off state. The 6H mode is especially suited to sites with defined activity hours such as gated society entry points and commercial parking lots. All modes are accessible via the included remote without physical access to the unit.
Solar Panel & Charging Efficiency
The 5V 23W monocrystalline solar panel integrated into the Aero Plus 1347 is the charging source for the 20Ah LiFePO4 battery across a 7–8 hour daily charge window. Monocrystalline silicon panels achieve conversion efficiencies of 19–22% under standard test conditions, outperforming polycrystalline alternatives (13–17%) in both direct and diffused light conditions. The latter is particularly relevant during India’s June–September monsoon season when cloud cover reduces irradiance, and polycrystalline-equipped competitors may fail to fully charge overnight capacity. The 7–8 hour charging time is consistent with peak solar hours available across most Indian states between October and May, and the monocrystalline panel’s superior low-light sensitivity helps maintain charging performance during the shorter, cloudier days of the November–January winter period in north India. The factory-integrated panel angle removes the need for on-site tilt calibration.
Installation & Mounting
The Aero Plus 1347 is designed for rapid, no-wiring installation. The solar panel, LiFePO4 battery, LED array, radar sensor, and controller are factory pre-assembled into the single Aero Plus housing. On-site work is limited to mounting the bracket onto a 45mm diameter pole at 4–5 metres height and securing the unit — a process typically completed in under 30 minutes per light. No electrical cabling, trenching, or grid connection is required, making the 1347 suitable for rural gram panchayat road tenders, colony development projects, farmhouse perimeter lighting, and off-grid construction site access roads where grid infrastructure is absent. Supplied at 5 units per carton, bulk procurement for housing societies, municipalities, and civil contractors is logistics-ready.
