Overview
The 15W Solar Flood Light Lens Model (Model 1281) is an all-in-one, semi-integrated off-grid solar flood light designed for compound and parking lot flood lighting, housing society compound perimeter and entrance lighting, industrial factory and warehouse exterior wall floodlighting, farmhouse estate boundary floodlighting, rural road and colony entrance signage lighting, and any Indian outdoor environment requiring high-output cool white solar flood illumination with remote control. Featuring 280 Pcs 2835 LED chips at a confirmed 140W LED power output, a 3.2V 20Ah LiFePO4 battery providing 12-14 hours of backup, a 5V 20W polycrystalline solar panel, remote control with Auto/On/Off/3H/5H/8H/Half/Full functions, and IP65 waterproofing, the Model 1281 delivers the highest LED output in the LumenCity 15W solar flood light specification. LiFePO4 chemistry at 20Ah provides the extended 12-14 hour backup and the confirmed 2,000+ cycle battery life appropriate for permanent outdoor compound and parking lot flood light installation across India. At 19.5× 27 × 6 cm, the flood light body mounts on any standard wall bracket or pole bracket and requires no mains wiring or grid connection.
LED Performance & Light Output – 280 Pcs 2835
The 15W Solar Flood Light Model 1281 integrates 280 Pcs 2835 LED chips at a confirmed 140W LED power output — producing cool white high-intensity flood illumination appropriate for compound perimeter floodlighting, parking lot area lighting, industrial factory exterior wall lighting, and rural road junction lighting. The 2835 SMD chip format at 280 chips delivers the high lumen output required for flood light applications where wide-area surface illumination at 3-8 metre mounting heights is the specification. Cool white at approximately 5000-6500K is the confirmed light colour, providing the bright, high-contrast illumination appropriate for security lighting, parking area visibility, and compound entrance identification at housing societies, factories, and rural commercial establishments in India. The Lens Model designation from the product specification confirms optical lens enhancement over the standard 2835 array — concentrating and directing the 280-chip output in a focused flood beam pattern appropriate for the wide-angle wall-mount flood lighting applications in the product photograph.
Battery – LiFePO4 3.2V 20Ah LiFePO4 & 12-14Hr Backup
The 3.2V 20Ah LiFePO4 battery in the 15W Solar Flood Light Model 1281 provides 12-14 hours of backup — the confirmed specification from the product image. LiFePO4 (Lithium Iron Phosphate) at 20Ah is the premium battery chemistry for solar flood lights in the Indian market. LiFePO4 delivers 2,000+ charge-discharge cycles versus 300-500 cycles for sealed lead-acid alternatives, and operates safely across India’s full outdoor temperature range — from sub-zero January nights in north Indian hill stations to 48-degree Celsius summer afternoons in Rajasthan — without the thermal instability of standard Li-ion at high temperatures. At 20Ah, the battery stores sufficient energy for the confirmed 12-14 hour backup across India’s longest winter nights in north Indian states. The 12-14 hour specification covers the full dusk-to-dawn cycle in all Indian states across all seasons. In Auto mode, the remote-controlled dimming from 100% to 70% to 30% across the night actively extends the 20Ah reserve to the full 12-14 hour specification.
Body Build & Weatherproofing – IP65
The 15W Solar Flood Light Model 1281 carries IP65 waterproofing — confirmed in the product specification. IP65 certifies complete dust ingress protection and resistance to water jets from any direction, the appropriate outdoor standard for permanently wall-mounted or pole-mounted solar flood lights in India’s full range of outdoor climate conditions. IP65 protects the 280-chip LED board, remote receiver, LiFePO4 battery pack, and driver circuitry from the monsoon rainfall of Kerala, Maharashtra, and the Western Ghats; the coastal salt-air of Goa, Mumbai, and Chennai; and the dust and UV exposure of Rajasthan and Gujarat. At 19.5× 27 × 6 cm, the Model 1281 is a standard flood light body size appropriate for compound perimeter wall mounting, pole top bracket installation, and factory exterior wall floodlighting. The ABS + PC body construction standard for this product category provides impact resistance and UV stability appropriate for year-round outdoor exposure.
Remote Control & Operating Modes
The 15W Solar Flood Light Model 1281 is controlled by a wireless remote with the following confirmed modes from the product specification. Auto mode: 100% brightness for the first 20 minutes, 70% for 4.5 hours, and 30% for remaining hours — the standard intelligent dimming mode that conserves the 20Ah LiFePO4 battery across the 12-14 hour cycle while providing maximum brightness during the high-traffic early evening period. On/Off mode: Light on and off via remote with sensor working. 3H mode: Illuminates for 3 hours then switches off — appropriate for timed early evening compound entrance lighting. 5H mode: Illuminates for 5 hours then switches off. 8H mode: Illuminates for 8 hours then switches off. Half mode: 50% brightness operation — extends runtime on short-solar monsoon days. Full mode: 100% brightness operation. The automatic dusk-to-dawn light sensor activates the flood light each evening without manual remote operation when Auto mode is active.
Solar Panel & Charging Efficiency – 5V 20W POLY
The 5V 20W polycrystalline solar panel supplies the daily energy harvest for the 15W Solar Flood Light Model 1281, charging the 20Ah LiFePO4 battery within 6-8 hours of direct sunlight. The polycrystalline specification is confirmed from the product image (POLY) — polycrystalline panels provide reliable energy harvest at a lower cost-per-watt than monocrystalline alternatives at the same panel surface area, appropriate for the compound perimeter and factory exterior wall installations where open-sky panel positioning is achievable. The 5V 20W panel provides the daily energy input required to replenish the 20Ah battery after the previous night’s Auto mode operation — where the battery is not fully depleted at 30% brightness for the later hours of the night. The panel connects to the flood light body via the semi-integrated wired panel cable, enabling the panel to be positioned for maximum daily solar irradiance independent of the flood light body mounting position.
Installation & Mounting
The 15W Solar Flood Light Model 1281 installs on any outdoor wall, pole, or bracket surface without mains power connection or underground cable. The flood light body mounts on a standard wall bracket or pole bracket using two mounting screws — appropriate for Indian compound perimeter walls, pole tops at parking lot entrances, factory exterior walls, and rural commercial establishment facades. The 5V 20W POLY panel mounts separately on the optimal south-facing skyward position to maximise daily solar harvest. No electrician, underground conduit, or switchboard connection is required. The remote control operates at the confirmed range specified and enables mode selection, brightness adjustment, and timer setting from a distance. For housing society compound perimeter flood lighting schemes where multiple 15W units are installed at different wall positions, the semi-integrated panel design enables each panel to face optimal irradiance without constraining the flood light body position.
