20W solar flood light – IP66 waterproof | 8-12Hr backup | Remote

Overview

The 20W Solar Flood Light (Model 1338) is the highest-output model in this range, engineered to provide powerful, wide-area illumination across large outdoor spaces without any dependency on grid electricity. Driven by a 6V 12W solar panel and a 3.2V 12AH battery, the 1338 sustains 8–12 hours of cool white LED lighting per night on a 6–8 hour solar charge. The IP66-rated enclosure provides complete protection against dust and high-velocity water jets, making it appropriate for installation in exposed locations including rural highways, large farmhouse perimeters, open community grounds, industrial approach roads, and outer boundary walls of housing societies. The included remote control supports Auto, On/Off, timed (3H, 5H, 8H), Half, and Full light modes, providing full flexibility for diverse usage scenarios across India.

LED Performance & Light Output

The 20W LED module represents the highest lumen output in the 1336–1338 range, capable of flooding large open areas with bright, even cool white light. At this wattage, the fixture is suitable for applications that demand genuine wide-area coverage — large parking lots, sports courts, industrial loading bays, community maidans, or the approach roads of gated colonies and farmhouses. Cool white LED output at 20W provides sharp contrast and visibility across the illuminated zone, which is particularly critical for security applications where recognition of persons, vehicles, and activity at a distance is necessary. The high-output LEDs are surface-mounted within a reflective housing to maximise forward beam efficiency.

Battery – 3.2V 12AH Capacity & Backup

The 3.2V 12AH battery in the 1338 is the largest in this product range, providing sufficient energy reserves to power the 20W LED module for 8–12 hours per night. The high capacity buffer is particularly valuable for locations where panel charging may be partially compromised by shading, seasonal overcast, or positioning constraints. Even with a partial charge, the 12AH battery retains enough stored energy to sustain several hours of operation at reduced brightness, unlike smaller batteries that may cut out entirely after consecutive cloudy days. For rural roads in Bihar, Jharkhand, or Assam — where grid access is unreliable and night-time lighting coverage is a safety priority — the 12AH battery provides the margin needed for dependable all-night operation.

Body Build & Weatherproofing

At 45 × 35 × 20 CM, the 1338 is the largest unit in the range, with a body sized to accommodate the 12AH battery and higher-output LED array. The IP66 waterproof and dustproof certification ensures the unit is sealed against both fine dust and powerful water jets, providing the same level of protection found in outdoor commercial and industrial luminaires. This rating is critical for Indian conditions: the combined assault of summer dust storms, monsoon deluges, coastal humidity, and wide seasonal temperature variation would degrade any unit not built to this standard. The body materials and sealing maintain structural and optical integrity across years of outdoor installation without requiring periodic servicing.

Smart Controls & Operating Modes

The remote control packaged with the 1338 provides the same comprehensive mode management as the rest of the range, but its value is amplified at 20W because manual brightness optimisation directly translates to meaningful battery savings. Auto mode — 100% for 20 minutes, 70% for 4.5 hours, 30% for remaining hours — is calibrated to balance visibility with battery longevity, ensuring the light is brightest when foot and vehicle traffic peaks just after dusk, and economical during the quieter late-night hours. Timed modes (3H, 5H, 8H) are useful for event venues, temporary outdoor setups, and commercial properties that need lighting only for defined hours. Full light mode delivers maximum output for applications requiring sustained high-brightness coverage.

Solar Panel & Charging Efficiency

The 6V 12W solar panel paired with the 1338 has the highest harvesting capacity in the range, enabling efficient charging of the 12AH battery within the 6–8 hour window. The panel is designed for separate surface mounting — on a roof parapet, wall-top, or dedicated pole bracket — and connects to the flood light body via cable. Independent positioning allows the user to optimise the panel’s sun-facing angle without being constrained by where the light fixture is mounted. In high-irradiance zones such as Rajasthan, Gujarat, and peninsular India, the 12W panel can achieve a near-full charge in 5–6 hours under clear skies, providing extra capacity buffer on longer winter nights or following partially cloudy days.

Installation & Mounting

Despite its higher power output, the 1338 installs without any electrical wiring, licensed electricians, or connection to the mains supply. The panel and flood light housing are separately wall or pole-mountable using the included hardware, linked by a plug-and-socket cable. At 45 × 35 × 20 CM, the body is best installed at height on a sturdy wall bracket or pole top for optimal light throw across the target area. Once mounted and connected, the system is entirely self-operating — activating at dusk according to the programmed mode and deactivating at dawn or timer completion. This off-grid, no-wiring installation model makes the 20W solar flood light the ideal primary outdoor lighting solution for large farmhouse perimeters, rural highway plots, community maidans, outer boundaries of housing societies, and industrial yards in areas underserved by reliable grid power.
