8W Solar Street Light – EPISTAR LED | IP65 | Dusk to Dawn

Overview

The 8W Solar Street Light (Star Model 1249) is an all-in-one, off-grid lighting solution designed for medium-narrow colony footpaths, housing society pedestrian lanes, gated community internal roads, small rural pathways, farmhouse boundary perimeters, and garden-to-road transition zones across India. With 384 LED 2835 EPISTAR chips at a combined 80W output in cool white and a 3.2V 10Ah LiFePO4 battery providing 1 night of illumination, the 8W Star Model occupies the mid-tier of the Star series — delivering double the LED count and battery capacity of the 4W model at the same compact form factor and 50mm pole specification. The 2 Window Star Model array distributes light more widely than the 4W single-window configuration, making the 1249 suitable for slightly wider paths and shared access areas in residential and mixed-use developments across India.

LED Performance & Light Output

The Star Model 1249 integrates 384 LED 2835 EPISTAR chips — exactly double the 4W model — producing a combined 80W output in cool white across a 2 Window optical array. The increased chip count and dual-window distribution delivers a wider illumination footprint than the 1248, extending coverage on medium-narrow paths of 2–3 metres width and shared pedestrian access zones in housing colonies and gated communities. EPISTAR 2835 chips provide the thermal reliability and consistent lumen maintenance required for outdoor solar fixtures that operate daily without maintenance intervention. Cool white output at 80W is appropriate for colony internal roads, parking bay access paths, and rural farm tracks where moving vehicles and pedestrians require reliable contrast illumination. The 1-night lighting duration is standard for the 10Ah LiFePO4 battery capacity at this wattage, with the radar sensor’s dimming logic extending effective runtime on low-traffic sites.

Battery – LiFePO4 10Ah Capacity & Backup

The 3.2V 10Ah LiFePO4 battery in the Star Model 1249 provides double the energy storage of the 4W model’s 5Ah unit, supporting the higher 80W LED draw of the 384-chip array across a full dusk-to-dawn cycle. LiFePO4 chemistry at this capacity level is a meaningful upgrade from the lead-acid or early Li-ion batteries still found in competing 8W solar lights at similar price points in the Indian market. For colony and society maintenance committees evaluating solar street lights on IndiaMart or Amazon.in, LiFePO4’s cycle life advantage (2,000+ cycles vs 300–500 for lead-acid) directly translates to lower total replacement cost over the installation life — a relevant consideration for common area lighting budgets. The 10Ah capacity also provides a modest buffer against partial-charging days during India’s monsoon season, when consecutive overcast days may prevent full battery replenishment from the 12W monocrystalline panel.

Body Build & Weatherproofing

The Star Model 1249 carries IP65 weatherproofing, certifying complete dust ingress protection and resistance to water jets in any direction — the appropriate standard for year-round outdoor operation across India. The unit dimensions are 36 × 23 × 20 cm, marginally wider than the 4W model to accommodate the expanded 384-chip LED array, while maintaining the same 50mm pole compatibility for consistent installation across both wattages in a single project. The 50mm pole specification is the most common diameter in the Indian residential and small commercial solar lighting pole market, covering the GI poles supplied by most colony development contractors and municipal vendors. IP65 makes the 1249 suitable for the humid coastal environments of Maharashtra and Goa, the heavy monsoon zones of Kerala and the north-east, and the dust-heavy semi-arid regions of Rajasthan and Gujarat without requiring seasonal maintenance or additional weatherproofing measures.

Smart Controls & Operating Modes

The 1249 features the same radar motion sensor and wireless remote control system as the 4W model, with identical operating modes: OFF, ALWAYS, INDUCTION (full radar dusk-to-dawn), and 2H, 4H, and 6H timed induction modes. At 80W output, the radar sensor’s 10%–100%–15% dimming sequence is more critical to single-night battery performance than at 4W — without dimming, constant 80W draw would exhaust the 10Ah LiFePO4 battery before completing a full 12-hour dusk-to-dawn cycle in winter. The intelligent dimming enables 1-night backup at this output level by reducing average consumption to approximately 25–35W across the full overnight period on low-to-medium traffic colony paths and rural village lanes. The 6H timed induction mode suits housing society main entrance gates and small parking access roads where full brightness is required during peak evening hours (6–10 PM) and low-level awareness lighting is sufficient thereafter.

Solar Panel & Charging Efficiency

The 5V 12W monocrystalline solar panel in the Star Model 1249 is 33% larger in peak wattage than the 9W panel in the 4W model, providing the proportionally greater daily energy harvest required to replenish the 10Ah battery within the 6–8 hour charging window. Monocrystalline efficiency of 19–22% ensures reliable charging across India’s varied seasonal irradiance conditions, including the monsoon-reduced irradiance that affects charging performance in competing polycrystalline-equipped solar street lights. For Indian buyers comparing solar street lights on IndiaMart or Amazon.in, the panel-to-battery ratio is a key indicator of whether a 1-night backup claim is technically credible — the 12W panel and 10Ah LiFePO4 combination in the 1249 is correctly matched for the stated backup duration under average Indian solar conditions. The pre-integrated panel eliminates on-site tilt adjustment requirements.

Installation & Mounting

Installation of the Star Model 1249 follows the same no-wiring, no-grid process as the 4W model. The fully pre-assembled unit bracket-mounts to a 50mm pole at 3–4 metres height, with no electrical connections required. The 3–4 metre height range covers the majority of narrow colony path and residential garden lighting applications in India, where higher poles would be structurally over-specified and visually intrusive in low-density residential settings. The 8W model is particularly relevant for gram panchayat lighting tenders that specify solar street lights for village foot-path networks, where multiple narrow-path units are required across a single village and the no-wiring benefit eliminates the civil works cost of underground cable installation. At 10 units per carton, logistics for bulk procurement across housing society projects and gram panchayat schemes are efficient and cost-effective.
