12W Solar Street Light – EPISTAR LED | IP65 | Dusk to Dawn

Overview

The 12W Solar Street Light (Star Model 1250) is the highest-wattage variant in the Star series, designed for medium-width colony internal roads, housing society pedestrian main paths, gated community access roads, rural gram panchayat main village lanes, small parking areas, and farmhouse primary access tracks across India. With 576 LED 2835 EPISTAR chips producing a combined 120W output in cool white and a 3.2V 15Ah LiFePO4 battery rated for 1 night of illumination at an installation height of 3–5 metres, the 12W Star Model bridges the gap between residential-grade garden lighting and entry-level road lighting applications. The 3 Window optical array produces a broader beam spread than the 1 and 2 Window variants, extending coverage across medium-width paths and shared access areas that lower-wattage Star models cannot adequately illuminate.

LED Performance & Light Output

The Star Model 1250 integrates 576 LED 2835 EPISTAR chips across a 3 Window array, producing a combined 120W output in cool white. With 50% more LED chips than the 8W model and triple the count of the 4W model, the 1250’s 3 Window configuration delivers a broader, higher-intensity illumination footprint appropriate for 3–5 metre mounting heights and medium-width colony roads of 3–5 metres cross-section. EPISTAR 2835 chips at this density provide consistent lumen output with excellent thermal control — a critical factor at the 120W combined output level where localised LED heating would reduce effective brightness and chip lifespan in lower-quality alternatives. At 5 metres installation height, the 12W Star Model’s beam pattern covers a significantly wider ground-level area than the lower-wattage variants, making it the recommended option for colony main internal roads, housing society entrance drives, and rural panchayat village main thoroughfares.

Battery – LiFePO4 15Ah Capacity & Backup

The 3.2V 15Ah LiFePO4 battery in the Star Model 1250 provides 50% more capacity than the 8W model’s 10Ah unit, supporting the higher 120W LED output of the 576-chip 3 Window array across a full dusk-to-dawn cycle. The 15Ah LiFePO4 specification is the largest in the Star series and correctly matched to the 1250’s output level — the 15W monocrystalline panel harvests sufficient energy during 6–8 hours of sunlight to replenish the battery for each subsequent night of operation. As with the other Star series models, the LiFePO4 chemistry provides a 2,000+ cycle service life compared to the 300–500 cycles typical of lead-acid alternatives at similar energy capacity, which is a significant total cost of ownership advantage for society maintenance committees and panchayat bodies managing unattended outdoor lighting installations. The sealed LiFePO4 pack in the all-in-one housing also eliminates the electrolyte maintenance and safety concerns associated with sealed lead-acid batteries in outdoor pole-mounted enclosures.

Body Build & Weatherproofing

The Star Model 1250 carries IP65 weatherproofing, certifying full dust protection and directional water resistance across all outdoor deployment conditions encountered in India. At 38 × 25 × 20 cm, the 12W unit is the physically largest in the Star series, accommodating the 576-chip 3 Window LED array and 15Ah LiFePO4 battery within a sealed housing that maintains the same 20 cm depth as the 4W and 8W models. Pole diameter compatibility is 50mm — consistent across all three Star wattages — allowing housing society projects, panchayat schemes, and colony developers to specify a single pole standard for all Star Model lighting zones, regardless of wattage selection per zone. The IP65 sealed housing is appropriate for the full range of Indian outdoor environments, from the high-humidity zones of the Western Ghats and north-east India to the high-UV, high-dust conditions of the Thar Desert region and Deccan plateau.

Smart Controls & Operating Modes

The Star Model 1250 incorporates the same radar motion sensor and remote control system as the 4W and 8W models. Sensor behaviour follows the series-standard 10% startup, 100% active, and 15% post-motion (30-second hold) dimming sequence. At 120W LED output, effective power management through the sensor dimming cycle is essential for maintaining single-night battery performance on low-to-medium traffic colony roads and rural village lanes — without dimming, constant 120W draw would deplete the 15Ah LiFePO4 battery in approximately 9 hours, falling short of a full 12-hour dusk-to-dawn cycle in winter. The remote control’s 2H, 4H, and 6H timed induction modes allow housing society committees and panchayat administrators to configure each light for its specific traffic pattern without on-site technical expertise. The 6H mode is the recommended configuration for colony main road gates and small parking area entry points where sustained full brightness is required for the first 4–6 evening hours only.

Solar Panel & Charging Efficiency

The 5V 15W monocrystalline solar panel integrated into the Star Model 1250 is the largest in the Star series, providing the daily energy harvest required to fully replenish the 15Ah LiFePO4 battery within 6–8 hours of direct sunlight. At 15W panel output, the 1250’s charging system is appropriately sized for the battery capacity — a ratio that is not always observed in competing 12W solar street lights on Amazon.in and IndiaMart, where lower panel wattages are sometimes paired with larger backup claims for marketing purposes. Monocrystalline efficiency of 19–22% provides reliable charging during diffused-light monsoon days and short-day north Indian winters, maintaining the 1-night backup specification across all 12 months of the Indian solar year in most states. The factory-integrated panel angle ensures uniform performance across project-scale deployments without site adjustment.

Installation & Mounting

Installation of the Star Model 1250 requires no wiring, trenching, or grid connection. The fully pre-assembled unit mounts on a 50mm pole at 3–5 metres height, the broadest installation height range in the Star series. At 5 metres, the 12W model covers the upper end of residential and entry-level commercial lighting pole heights, making it appropriate for colony main internal roads, society compound perimeter lighting, and panchayat village main lane lighting where a 3-metre 4W or 8W installation would be visually insufficient. The off-grid design is directly relevant to gram panchayat and housing society projects where extending the grid to all lighting points is cost-prohibitive or technically delayed. The 5-unit-per-carton packaging reflects the larger unit size and supports project-scale procurement by society developers, municipal contractors, and rural development scheme administrators. The shared 50mm pole specification with the 4W and 8W models enables a single pole specification across all three wattages within a single project.
