Overview
The 35W Solar Street Light (Space Model 1351) is a high-output, all-in-one off-grid lighting fixture designed for medium-width roads, large parking areas, highway service lanes, industrial campuses, and housing society main roads across India. Incorporating 72 LED 5054 chips at 400W LED power and a 3.2V 30Ah LiFePO4 battery, the 1351 delivers bright, sustained cool white illumination for up to 12 hours per charge cycle. With an installation height of 5 to 7 metres, this model is suited to applications requiring a wider coverage footprint and greater mounting clearance than lower-wattage units. The integrated 12-lens Space Model optic array further extends beam distribution relative to the 9-lens variant.
LED Performance & Light Output
The 35W model integrates 72 LED 5054 chips rated at 400W LED power output in cool white, making it appropriate for medium-to-high traffic zones including colony main roads, commercial parking lots, farmhouse access drives, and rural national highway service roads. The 12-lens optical array in the Space Model 1351 provides a broader illumination spread compared to the 9-lens 25W variant, reducing the number of poles required per unit of road length and lowering overall project cost. LED 5054 chips are chosen for their thermal management properties, which are essential for consistent lumen output across the high-temperature operating conditions prevalent in Indian summers. The 12-hour daily lighting duration covers a full dusk-to-dawn cycle.
Battery – LiFePO4 30Ah Capacity & Backup
The 3.2V 30Ah LiFePO4 battery in the 1351 provides 25% greater storage capacity than the 24Ah unit in the 25W model, supporting the higher power draw of the 72-LED array across the same 12-hour lighting window. LiFePO4 chemistry is markedly superior to lead-acid batteries commonly found in lower-priced solar street lights in India. Lead-acid cells degrade rapidly under the deep discharge cycles inherent in dusk-to-dawn solar lighting, particularly during monsoon or winter months with reduced solar input. LiFePO4 batteries, by contrast, maintain over 80% capacity after 2,000 cycles, equivalent to over five years of daily operation. The chemistry also poses no thermal runaway risk, an important safety consideration for unattended outdoor installations.
Body Build & Weatherproofing
The Space Model 1351 carries an IP65 rating, confirming protection against total dust ingress and resistance to water jets from any direction — a critical requirement for year-round outdoor deployment across India’s diverse climate zones. The compact body measures 28 x 3 x 85 cm, slightly longer than the 25W model to accommodate the increased battery and LED array. Pole diameter compatibility is identical at 40–50mm, ensuring the 35W unit can be deployed on the same pole stock as the 25W model for mixed installations. The aerodynamic housing profile minimises wind-induced vibration at the 5–7 metre installation height, which is particularly relevant in coastal and high-altitude locations.
Smart Controls & Operating Modes
The 1351 includes the same radar motion sensor and wireless remote control system as the 25W model, with identical operating modes. Optical 10% brightness at startup, 100% brightness on radar detection, and 20% brightness after 30 seconds of no movement ensure efficient battery utilisation across variable-traffic sites. Remote control modes — OFF/ON, AUTO, RADAR, and 2H/3H/4H induction timers — allow facility managers and housing society committees to customise operation for different zones within a single project. The RADAR mode is particularly effective for high-security applications such as warehouse perimeter roads, industrial estate access gates, and rural petrol stations where full brightness on demand is essential without sustaining 100% output all night.
Solar Panel & Charging Efficiency
The 5V 30W monocrystalline solar panel of the Space Model 1351 delivers 30% greater peak wattage than the 23W panel in the 25W model, providing the additional charging capacity required to replenish the larger 30Ah LiFePO4 battery within 5 to 7 hours of direct sunlight. Monocrystalline panels maintain a higher conversion rate than polycrystalline alternatives under both optimal and sub-optimal irradiance conditions — a meaningful advantage during India’s monsoon months when solar intensity is reduced. The factory-integrated panel orientation eliminates site-level tilt adjustments and ensures repeatable performance across bulk installations.
Installation & Mounting
Installation of the Space Model 1351 follows the same no-wiring, off-grid process as the 25W model. The fully pre-assembled unit is mounted to a 40–50mm pole at a height of 5 to 7 metres, with no electrical connections to external infrastructure. This makes the 35W model well-suited to greenfield road lighting projects in peri-urban developments, rural gram panchayat roads, industrial estate perimeters, and large farmhouse estates where grid extension costs are prohibitive. At 5 units per carton, logistics for medium and large procurement volumes are manageable, and the identical pole specification across both 25W and 35W models simplifies supply chain management for projects deploying both wattages.
