9W Solar Street Light – EPISTAR LED | IP65 | Dusk to Dawn

Overview

The 9W Solar Street Light (Double Body Model 1119, 3 Window) is an all-in-one off-grid lighting solution designed for medium-width housing colony internal roads, housing society main pedestrian corridors, gated community access tracks, rural gram panchayat village main lanes, small parking areas, and farmhouse primary access roads across India. With 240 LED 5730 EPISTAR chips producing a combined 90W output in cool white and a 3.2V 15Ah LiFePO4 battery rated for 8–12 hours (1 night) of illumination under ideal sensor conditions, the 9W Double Body 1119 is the mid-tier of the single-night backup group and the most versatile wattage in the series for residential-to-light-commercial transition zones. The 3 Window Double Body array provides a broader beam pattern than the 1 and 2 Window lower variants, extending road coverage at the 3–5 metre installation height appropriate for colony main internal roads and shared access tracks.

LED Performance & Light Output

The Double Body 1119 integrates 240 LED 5730 EPISTAR chips across a 3 Window array at a combined 90W output in cool white. The 3 Window configuration produces a significantly wider illumination footprint than the 1 and 2 Window lower-wattage models, enabling effective road coverage at 3–5 metre mounting heights on medium-width colony roads and housing society main pedestrian routes. EPISTAR 5730 chips at 240 count provide the thermal mass and lumen maintenance required for consistent output across India’s high-ambient-temperature outdoor environments — a relevant consideration for the 9W output level where LED junction heating is more significant than at lower wattages. Cool white output at 90W provides the brightness and contrast appropriate for slow-moving vehicle access roads and pedestrian-vehicle shared zones in residential colonies and rural village main lanes.

Battery – LiFePO4 15Ah Capacity & Backup

The 3.2V 15Ah LiFePO4 battery in the Double Body 1119 is 25% larger than the 6W model’s 12Ah unit, supporting the higher 90W LED draw across 8–12 hours of dusk-to-dawn operation under ideal sensor-dimming conditions. The 15Ah LiFePO4 battery at this discharge rate also provides a more meaningful buffer against partial-charging monsoon days compared to the smaller batteries in the 3W and 6W models, maintaining 1-night backup performance in most Indian solar zones even during consecutive overcast days that prevent full replenishment. LiFePO4’s 2,000+ cycle lifespan is particularly relevant at the 9W tier, where the product is more likely to be deployed on shared-access colony roads and panchayat main lanes that are scheduled for long-term lighting infrastructure rather than temporary or personal-use garden lighting.

Body Build & Weatherproofing

The Double Body 1119 carries IP65 weatherproofing, confirming complete dust ingress protection and water jet resistance across India’s diverse outdoor climate conditions. At 50 × 23.5 × 11 cm, the 9W Double Body is the widest single-night-backup model in the series, accommodating the 240-chip 3 Window LED array within a sealed housing. Pole diameter compatibility is 50mm, matching the most common residential and semi-commercial GI pole specification in India and enabling unified pole procurement for mixed 6W and 9W deployments within a single project. The 11 cm depth is marginal compared to the 10 cm depth of the 3W and 6W models, providing the additional volume required for the 15Ah battery without increasing the housing’s aerodynamic footprint meaningfully at the 3–5 metre installation height.

Smart Controls & Operating Modes

The 1119 includes the same radar sensor and remote control system as all Double Body variants. The 10%–100%–15% sensor dimming is more consequential at 90W output than at lower wattages — without effective dimming, sustained 90W draw would deplete the 15Ah LiFePO4 battery in approximately 11–12 hours, leaving no reserve for the late pre-dawn period. The sensor-managed dimming reduces effective average consumption to approximately 30–40W across a typical overnight cycle on low-to-medium traffic colony roads and rural village main lanes, comfortably delivering 8–12 hour runtime within the LiFePO4 battery’s capacity. The 4H and 6H timed induction modes are the recommended configurations for colony main access road lighting, where sustained full brightness is required for the 6–10 PM peak period and low-level illumination is appropriate for the remainder of the night.

Solar Panel & Charging Efficiency

The 5V 12W monocrystalline solar panel in the Double Body 1119 provides the daily energy harvest needed to replenish the 15Ah LiFePO4 battery within the standard 6–8 hour charging window. At 12W panel output paired with 15Ah battery capacity, the 9W model’s charging ratio is well-balanced for the stated 1-night backup claim across most Indian solar zones. Monocrystalline efficiency of 19–22% maintains charging performance under the diffused irradiance conditions of the monsoon season and the lower sun angles of north Indian winters, reducing the risk of under-charge failures that commonly affect polycrystalline-equipped competing solar street lights at this wattage on Indian solar review sites and IndiaMart buyer feedback.

Installation & Mounting

The Double Body 1119 installs without grid wiring or trenching. The pre-assembled unit mounts on a 50mm pole at 3–5 metres height, the widest installation height range in the single-night-backup group of the Double Body series. At 5 metres, the 9W 3 Window array covers medium-width colony roads and panchayat village main lanes without dark-spot gaps between pole positions. The off-grid design eliminates the civil works cost of underground cable installation — a primary cost driver in rural and peri-urban road lighting projects across India — making the 1119 a cost-effective specification for gram panchayat lighting tenders and housing society internal road schemes. Supplied at 5 units per carton.
