25 Watt | 12 Hours Backup | IP66 Rating | Day & Night Sensor | Radar Sensor | Battery Level Indicator – Solar Street Light

Overview

The 25W Solar Street Light (Space Model 1350) is a self-contained, off-grid outdoor lighting solution that integrates a solar panel, LiFePO4 battery, LED module, motion sensor, and controller into a single compact unit. Rated at 300W LED power with 54 LED 5054 chips, it is engineered for installation on colony roads, housing society entry gates, parking lots, rural pathways, farmhouse driveways, and suburban streets across India. Delivering 12 hours of backup from a single charge, the 1350 combines a Day & Night Sensor for automatic dusk-to-dawn switching, a Radar Sensor for intelligent motion-based brightness control, and a Battery Level Indicator for at-a-glance charge status monitoring — all housed in an IP66-rated all-in-one Space Model body at 4–5 metre installation height, with no external wiring or grid connection required.

LED Performance & Light Output

The 25W Space Model 1350 houses 54 LED 5054 chips delivering a combined 300W equivalent output in cool white light. LED 5054 chips are high-lumen-density emitters preferred in commercial outdoor lighting for their superior efficacy and thermal stability compared to earlier SMD variants. Cool white light output is optimal for road illumination, parking areas, and perimeter security where visibility and contrast are critical. The 12-hour lighting duration per full charge cycle ensures the unit operates reliably from dusk to dawn under standard Indian solar insolation conditions. The 9-lens Space Model optical configuration ensures wide, even beam distribution across the intended coverage area at 4–5 metre installation height.

Battery – LiFePO4 24Ah Capacity & 12-Hour Backup

The integrated 3.2V 24Ah LiFePO4 (Lithium Iron Phosphate) battery is a key differentiator of the Space Model 1350 when compared to solar street lights using lead-acid or standard Li-ion cells. LiFePO4 chemistry offers a cycle life exceeding 2,000 charge-discharge cycles, translating to over five years of reliable daily operation in most Indian climate zones. Unlike lead-acid batteries, LiFePO4 does not suffer from sulphation or capacity loss under partial-state-of-charge conditions, which is common during overcast monsoon periods across coastal and central India. The battery is also inherently thermally stable, making it suitable for high-ambient-temperature environments in Rajasthan, Gujarat, and other states where summer temperatures frequently exceed 40°C. The integrated Battery Level Indicator allows users and maintenance teams to check the charge status of the 24Ah LiFePO4 battery at a glance — without dismounting the unit — enabling proactive maintenance scheduling across multi-light colony road and housing society installations.

Body Build & Weatherproofing

The Space Model 1350 carries an IP66 weatherproofing certification, confirming complete protection against dust ingress and resistance to high-pressure water jets from any direction — a rating that exceeds the standard IP64 and IP65 of most competing solar street lights in this wattage segment. IP66 makes the 1350 suitable for permanent outdoor installation across India’s full climate range, from heavy monsoon rainfall on the western and eastern coasts to high-dust semi-arid conditions in Rajasthan and Punjab. The slim housing dimension of 28 × 3 × 72 cm ensures an aerodynamic profile that reduces wind load on the mounting arm at the 4–5 metre installation height. Pole compatibility of 40–50mm diameter covers the majority of standard Indian municipal and private street lighting poles, enabling direct retrofit installation in existing infrastructure without custom adapters.

Smart Controls – Day & Night Sensor | Radar Sensor | Battery Level Indicator

The Space Model 1350 operates automatically through two integrated sensing systems — a Day & Night Sensor and a Radar Sensor — supported by a Battery Level Indicator and a wireless remote control for additional mode flexibility. The Day & Night Sensor activates the unit automatically at dusk and switches it off at dawn every day without manual input, ensuring consistent dusk-to-dawn coverage across all seasons. The Radar Sensor manages a three-state brightness sequence: 10% standby brightness during inactive periods, 100% full brightness on motion detection, and 20% brightness for 30 seconds post-motion before returning to standby — the key enabler of the 12-hour backup by conserving battery during low-traffic overnight periods. The Battery Level Indicator provides visible charge status monitoring, allowing facility managers and maintenance staff to assess battery health across colony road and parking lot installations without physical access to each unit. Remote control modes include AUTO (motion-activated dusk-to-dawn), RADAR (full radar with dusk-to-dawn switching), timed induction modes at 2H, 3H, and 4H intervals, and manual ON/OFF — with remote brightness adjustment for site-specific tuning.

Solar Panel & Charging Efficiency

The 5V 23W monocrystalline solar panel integrated into the Space Model 1350 replenishes the 24Ah LiFePO4 battery within 5–7 hours of direct sunlight. Monocrystalline silicon cells achieve higher conversion efficiencies of 19–22% under both direct and diffused sunlight conditions — particularly relevant during India’s monsoon season when cloud cover can persist for days across coastal, north-eastern, and central regions, and during the shorter, lower-angle solar days of north Indian winters (November–January). The factory-aligned panel angle removes the need for on-site tilt calibration, ensuring consistent charging performance across all installation orientations and across bulk colony and municipal deployments managed by non-specialist maintenance personnel.

Installation & Mounting

The Space Model 1350 is designed for rapid, no-wiring installation. All components — solar panel, LiFePO4 battery, LED module, Day & Night Sensor, Radar Sensor, Battery Level Indicator, and controller — are pre-assembled in the factory. On-site work is limited to mounting the bracket onto a 40–50mm diameter pole at 4–5 metres height and securing the unit. No trenching, conduit work, or electrical connection to the grid is required, making the 1350 especially suitable for rural roads, construction sites, peri-urban colonies, and agricultural perimeters where grid infrastructure is absent or cost-prohibitive. Supplied in cartons of 5 units, bulk procurement for housing societies, gram panchayats, and municipalities is straightforward.
