15W Solar Street Light Aero – 12 Hours Backup | EPISTAR LED | IP65

Overview

The 15W Solar Street Light Aero Design (Model 1183) is an all-in-one, off-grid solar street light delivering 12 Hours of consecutive backup — the most critical performance differentiator for solar street lights on the Indian market. Designed for housing colony internal road lighting, housing society compound and parking lot lighting, farmhouse driveway and estate road lighting, rural road and village pathway lighting, institutional campus walkways, and any Indian outdoor environment requiring solar street lighting with extended multi-night autonomous operation. Featuring 480 Pcs 5730 EPISTAR LED chips at 200W LED Power, a 3.2V 20Ah LiFePO4 battery, a 5V 23W monocrystalline solar panel, remote control, and a 55 × 34.2 × 10 cm housing, the Model 1183 is the premium variant in the LumenCity 15W Aero Design range — upgraded from the Model 1250 Aero at 450 LED / 15W panel / 15A LiFePO4 with single-night backup to 480 LED / 23W MONO panel / 20A LiFePO4 with 12 Hours backup. This upgrade makes the Model 1183 the specification for Indian buyers in high-latitude north Indian states (Punjab, Haryana, Himachal Pradesh, Uttarakhand, Uttar Pradesh) where winter nights of 12+ hours require longer backup than single-night alternatives can provide.

LED Performance & Light Output – 480 Pcs 5730 EPISTAR | 200W

The 15W Solar Street Light Aero Design Model 1183 integrates 480 Pcs 5730 EPISTAR LED chips at 200W LED Power delivering cool white output. The 5730 EPISTAR chip specification is confirmed premium — EPISTAR is the Taiwanese LED manufacturer whose chips are specified across the LumenCity solar street light range for consistent, verified LED quality. At 480 chips and 200W LED Power, the Model 1183 delivers the highest LED chip count and LED power in the LumenCity 15W Aero range, surpassing the Model 1250 Aero at 450 chips and lower LED power. The 5730 chip provides the broad, even cool white road illumination appropriate for housing colony internal road lighting, compound walkway lighting, and parking lot area lighting at the 4-6 metre installation height confirmed in the product specification. Cool white output provides the maximum road surface contrast appropriate for vehicle and pedestrian visibility on Indian rural roads, colony internal roads, and compound driveways.

Battery – LiFePO4 3.2V 20Ah & 12 Hours Backup

The 3.2V 20Ah LiFePO4 battery in the 15W Solar Street Light Aero Design Model 1183 provides 12 Hours of confirmed backup — the specification from the product image. This 2-Night backup is the primary purchase differentiator for the Model 1183 versus the standard 1-night backup of the Model 1250 Aero and versus competitors at this wattage. LiFePO4 (Lithium Iron Phosphate) at 20Ah delivers 2,000+ charge-discharge cycles — more than five years of daily operation — with stable thermal performance from north Indian sub-zero winter nights through Rajasthan 48-degree summer afternoons. The 2-Night specification means the Model 1183 continues to illuminate for a second full night from battery reserves when the first day’s solar harvest is insufficient for a full charge — critical for India’s monsoon season in Kerala, Karnataka, Maharashtra, and the Western Ghats where consecutive overcast days reduce daily panel output.

Body Build & Dimensions – Aero Design, 55 × 34.2 × 10 cm

The 15W Solar Street Light Aero Design Model 1183 measures 55 × 34.2 × 10 cm — the confirmed outer dimensions from the product specification. The Aero Design body is the wide, multi-panel housing format visible in the product photograph — 6 LED panel arrays arranged across the 55 × 34.2 cm face, providing the broad even cool white illumination from the wider aperture compared to the single-panel Aero models. At 10 cm depth, the Aero housing mounts on the 45 mm pole diameter confirmed in the specification, with a confirmed installation height of 4-6 metres appropriate for housing colony internal roads (typically 4 m) through compound entrance lighting (up to 6 m). The remote control confirmed in the product image enables mode selection and operational adjustment from the ground without ladder access after installation.

Remote Control & Smart Operation

The 15W Solar Street Light Aero Design Model 1183 is operated by a wireless remote — confirmed in the product image. The remote enables mode selection, brightness adjustment, and timer setting from the ground at the pole base after installation without ladder or tool access. Remote control is standard across the LumenCity Aero Design range. Auto dusk-to-dawn optical switching activates the LED output each evening without manual remote operation under the default setting. For housing society compound and parking lot solar street light installations where multiple units are installed on the same compound, the remote enables coordinated mode adjustment across all units from a central position. The 12 Hours backup specification means the remote mode selections — including any dimming or timed modes — are managed within the context of the extended 20Ah battery reserve.

Solar Panel – 5V 23W Monocrystalline & Charging Efficiency

The 5V 23W monocrystalline (MONO) solar panel in the 15W Solar Street Light Aero Design Model 1183 is the primary technical reason the Model 1183 achieves 12 Hours backup versus the single-night backup of competitors using polycrystalline panels at lower wattage. Monocrystalline panels provide higher conversion efficiency — typically 19-22% versus 15-17% for polycrystalline panels at the same surface area — enabling the 23W MONO panel to harvest more daily solar energy than a 15W or 18W polycrystalline alternative in the same panel footprint. For Indian housing colony and rural road solar street light applications in states with variable irradiance — cloudy Maharashtra, Kerala, and the Western Ghats in monsoon season — the higher-efficiency 23W MONO panel maximises daily harvest and recharge of the 20Ah LiFePO4 battery to extend the consecutive 2-Night backup duration even on partially overcast days.

Installation & Pole Mounting – 45mm, 4-6M, No Wiring

The 15W Solar Street Light Aero Design Model 1183 installs on any 45 mm diameter pole at 4-6 metres installation height without mains power connection, underground cable, or electrician engagement. The all-in-one housing integrates the 480-chip LED array, 23W MONO panel, 20Ah LiFePO4 battery, and remote receiver in a single unit that mounts directly on the pole top bracket using the 45 mm pole adapter. No wiring between separate panel and light body is required — the entire unit attaches as a single assembly. For housing colony developers installing solar street lights on internal colony roads, the off-grid design eliminates the underground power cabling cost — the largest single installation cost component for conventional wired street lighting. At 5 PCS per carton, the Model 1183 is supplied for both individual replacement and small-batch colony road installation projects.
