Overview
The 20W Solar Flood Light Lens Model (Model 1280) is an all-in-one, semi-integrated off-grid solar flood light designed for large compound and parking lot flood lighting, housing society compound perimeter and entrance area floodlighting, industrial factory and warehouse exterior wall lighting, farmhouse estate boundary and approach road lighting, rural road junction and petrol station lighting, and any Indian outdoor environment requiring the highest-output cool white solar flood illumination at 20W with remote control. Featuring 400 Pcs 2835 LED chips at 200W LED power output — 43% higher LED count and 43% more power than the 15W Model 12B1 — a 3.2V 25Ah LiFePO4 battery, a 5V 30W polycrystalline panel, and the same remote control system as the 15W model, the 1280 is the premium variant in the LumenCity solar flood light range. The larger 400-chip LED array and 30W panel versus the 12B1’s 280 chips and 20W panel enables higher sustained illumination intensity across the 12-14 hour backup. IP65 waterproofing and the full Auto/On/Off/3H/5H/8H/Half/Full remote mode set confirm the 1280 as the specification for heavy-duty compound perimeter, factory exterior, and large parking area solar flood lighting.
LED Performance & Light Output – 400 Pcs 2835
The 20W Solar Flood Light Model 1280 integrates 400 Pcs 2835 LED chips at 200W LED power output — the highest specification in the LumenCity solar flood light range. At 400 chips versus the 12B1’s 280 chips, the Model 1280 delivers 43% more LED surface coverage and proportionally greater luminous flux, appropriate for larger compound perimeter floodlighting zones, wider parking lot areas, and taller factory exterior wall mounting heights of 5-10 metres where the 15W model’s 280-chip output would provide insufficient coverage. Cool white at approximately 5000-6500K is the confirmed light colour — providing the maximum contrast and visibility for security floodlighting, vehicle parking area lighting, and compound entrance identification at Indian housing societies, industrial establishments, and rural commercial facilities. The Lens Model optical enhancement concentrates the 400-chip output in the required flood beam pattern for wide-area wall-mount flood light coverage at the 5V 30W panel and 25Ah LiFePO4 battery tier.
Battery – LiFePO4 3.2V 25Ah LiFePO4 & 12-14Hr Backup
The 3.2V 25Ah LiFePO4 battery in the 20W Solar Flood Light Model 1280 provides 12-14 hours of backup — 25% more battery capacity than the 15W Model 12B1’s 20Ah, enabling the higher 200W LED draw of the 400-chip array to achieve the same 12-14 hour specification as the smaller model. LiFePO4 at 25Ah provides 2,000+ charge-discharge cycles — more than five years of daily operation — with stable thermal performance across India’s full outdoor temperature extremes. At 25Ah, the battery stores the maximum energy reserve in the LumenCity solar flood light range, providing the best monsoon-season resilience for compound perimeter floodlighting installations in high-rainfall zones of Kerala, Karnataka, the Western Ghats, and north-east India, where consecutive overcast days reduce daily panel output and the larger battery reserve maintains 12-14 hour backup without full daily recharge. The Auto remote mode — 100% for 20 minutes, 70% for 4.5 hours, 30% for remaining hours — actively manages the 25Ah reserve across the full night cycle.
Body Build & Weatherproofing – IP65
The 20W Solar Flood Light Model 1280 carries IP65 waterproofing and measures 32.8 x 6 x 25.5 cm — larger than the 15W Model 12B1 at 27 x 6 x 19.5 cm, reflecting the wider LED board required for 400 versus 280 chips. The 32.8 cm width accommodates the full 400-chip 2835 LED array in the flood light body. IP65 certification confirms complete dust protection and water jet resistance appropriate for permanently installed outdoor flood lights across all Indian climate zones. The shared 6 cm body depth between the 1280 and 12B1 confirms both models use the same slim flood light body profile — appropriate for standard wall bracket and pole bracket installation without additional structural support. For housing society compound perimeter floodlighting and factory exterior wall lighting where multiple units are installed across a large perimeter, the 1280’s larger body and 400-chip output is appropriate for the longer perimeter spans and taller mounting heights that require the premium 20W specification.
Remote Control & Operating Modes
The 20W Solar Flood Light Model 1280 uses the identical remote control system as the 15W Model 12B1 — all seven confirmed modes apply equally to both models. Auto mode: 100% for 20 minutes, 70% for 4.5 hours, 30% for remaining hours. On/Off mode. 3H, 5H, 8H timed modes. Half and Full brightness modes. For the 20W Model 1280 with its higher 200W LED power draw, Auto mode is the most critical battery conservation mechanism — the step-down from 100% to 70% to 30% across the night ensures the 25Ah LiFePO4 battery sustains the full 12-14 hour specification even at the 400-chip LED draw. In Half mode at 50% of 200W, the Model 1280 operates at 100W equivalent LED output — still brighter than many competing 100W wattage-equivalent solar flood lights on Amazon.in India, while extending battery life proportionally. The 8H timed mode is the recommended daily setting for compound perimeter lighting where full-night operation is not required and battery conservation for the following day is the priority.
Solar Panel & Charging Efficiency – 5V 30W POLY
The 5V 30W polycrystalline solar panel in the 20W Solar Flood Light Model 1280 is the largest panel in the LumenCity solar flood light range — 50% larger than the 15W Model 12B1’s 5V 20W panel. The 5V 30W POLY panel provides proportionally greater daily energy harvest, enabling the 25Ah LiFePO4 battery to be replenished after Auto mode operation within the confirmed 6-8 hour charging window. At 30W panel output, the Model 1280 provides better charging resilience on partially overcast monsoon days in Kerala, Karnataka, and the Western Ghats — where the 30W panel achieves sufficient daily harvest under diffused irradiance to maintain 12-14 hour Auto mode operation across consecutive moderate-overcast days. For Indian housing society compound perimeter flood lighting installations in high-rainfall monsoon zones, the 1280’s 30W panel versus the 12B1’s 20W panel is the primary specification advantage for monsoon-season charging reliability. The panel connects to the flood light body via the semi-integrated cable, enabling south-facing skyward panel positioning independent of flood light mounting direction.
Installation & Mounting
The 20W Solar Flood Light Model 1280 installs on any outdoor wall, pole, or bracket surface without mains power connection or underground cable. The larger 32.8 x 6 x 25.5 cm flood light body mounts on a standard heavy-duty wall bracket or pole bracket using the mounting holes in the housing back. The 5V 30W POLY panel is installed separately on the optimal south-facing position, connected to the flood light body via the panel cable. For large compound perimeter and factory exterior wall floodlighting projects where the 20W Model 1280 is specified for multiple positions across a wide perimeter, the semi-integrated cable design enables each panel to face optimal irradiance while the flood light bodies are positioned for maximum coverage of the compound area. No grid connection, underground conduit, or switchboard is required at any installation position. The remote control operates all mode functions during and after installation. For Indian procurement buyers specifying the 20W flood light for housing society compound schemes and industrial facility exterior lighting, 10 units per carton enables direct bulk procurement.
