Overview
The Solar Outdoor Wall Light – Optically Controlled Sensor (Model 1218, Pack of 4) is an all-in-one, off-grid solar wall light supplied as a pack of 4 units, designed for housing colony compound entrance walls, housing society boundary walls, hotel and resort exterior perimeter panels, farmhouse entrance and exterior walls, residential gate pillars, staircase walls, porch surfaces, and any Indian outdoor wall surface requiring reliable warm-white dusk-to-dawn illumination without mains wiring. Each unit in the pack features 6 Lens LED output in warm white, optically controlled auto on/off operation — activating automatically at dusk and switching off at dawn via the integrated optical sensor — IP65 waterproofing, and a compact 6.5 x 10 x 2.5 cm wall mount housing. A 3W solar panel charges the 1.5V 1800mAh battery within 6-8 hours daily. The Pack of 4 format enables complete coverage of a standard compound entrance — two units per gate pillar or entrance wall — or a full set of four boundary wall lights in a single procurement. The optically controlled auto switch distinguishes this product from motion-sensor solar wall lights, providing continuous warm-white illumination from dusk to dawn without triggering on and off.
LED Performance & Light Output – 6 Lens Warm White
Each Solar Outdoor Wall Light in the Pack of 4 (Model 1218) features 6 Lens LED output producing warm white illumination. The 6-lens configuration distributes LED output across six optical lenses in the compact 6.5 x 10 x 2.5 cm housing — providing broader, more uniform warm white illumination from the wall mount position than a single-lens alternative at the same housing size. Warm white at approximately 3000K is the confirmed light colour, appropriate for housing society compound boundary walls, hotel exterior facade panels, and farmhouse entrance walls where warm, welcoming ambient light quality is preferred over cool white for residential and hospitality environments. The optically controlled sensor design means each unit operates at consistent warm white output throughout the dusk-to-dawn cycle — without the brightness variation or switching behaviour of PIR motion-sensor solar wall lights. On Amazon.in and IndiaMart, “solar lights outdoor auto on/off” and “solar wall light dusk to dawn” are confirmed high-purchase-intent buyer search phrases for this product category.
Battery – 1.5V 1800mAh Capacity & Backup (Per Unit)
Each unit in the Solar Outdoor Wall Light Pack of 4 (Model 1218) contains a 1.5V 1800mAh battery confirmed in the product specification. The 1.5V cell voltage is characteristic of Nickel-Metal Hydride (Ni-MH) rechargeable chemistry — the standard battery type for compact solar wall lights in this form factor, providing the energy density required for the 6-lens LED array within the slim 6.5 x 10 x 2.5 cm housing. At 1800mAh, the battery capacity is at the premium end of the Ni-MH solar wall light category on Amazon.in and IndiaMart, where competing solar outdoor wall lights at equivalent price points typically specify 800-1200mAh cells. The 1800mAh capacity at 1.5V enables the 8-12 hour dusk-to-dawn operation across India’s range of night lengths — from 10-hour summer nights in south India to 14-hour winter nights in north Indian states. The battery charges automatically from the integrated 3W solar panel during daylight hours. Each of the 4 units operates as an independent solar-charged system with its own battery and panel.
Body Build & Weatherproofing – IP65, 6.5 x 10 x 2.5 cm
Each unit in the Solar Outdoor Wall Light Pack of 4 (Model 1218) 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 solar wall lights deployed year-round across India’s full range of climate conditions. IP65 protects each unit’s 6-lens LED array, optical sensor, driver circuitry, and 1800mAh battery from the monsoon rainfall of Kerala, Maharashtra, and the Western Ghats; the coastal salt-air humidity of Mumbai, Goa, and Chennai; and the dust and UV exposure of Rajasthan and Gujarat. At 6.5 x 10 x 2.5 cm, each unit has the most compact wall mount footprint of any solar wall light in the LumenCity range — the slim 2.5 cm depth keeps the housing almost flush to the wall surface, minimising visual projection from the compound boundary wall, gate pillar, or porch surface. The compact, silver-toned housing visible in the product photograph presents a clean, architectural aesthetic appropriate for housing society entrance walls, hotel exterior facades, and residential porch surfaces.
Optically Controlled Sensor – Auto On at Dusk, Auto Off at Dawn
Each Solar Outdoor Wall Light in the Pack of 4 (Model 1218) operates via optically controlled automatic switching — confirmed as “Auto Switch on at Night, Auto Switch off in Day (Charging)” in the product specification. The integrated optical (LDR — Light Dependent Resistor) sensor detects ambient light levels and activates the warm white LED output when ambient light drops below the dusk threshold each evening, and deactivates it when daylight rises above the dawn threshold each morning. During daytime switch-off, the 3W solar panel charges the 1800mAh battery for the following night’s operation. This optically controlled dusk-to-dawn operation is the primary differentiator from PIR motion-sensor solar wall lights — where PIR sensors trigger on movement and switch off after a preset interval, the optical sensor in the Model 1218 provides continuous, consistent warm-white illumination from dusk to dawn without any motion-triggered switching. On Indian housing society compound walls and residential gate pillars, continuous all-night illumination without motion-triggered on-off interruption is the confirmed buyer preference in this product category.
Solar Panel & Charging Efficiency – 3W (Per Unit)
The 3W solar panel integrated into each unit of the Solar Outdoor Wall Light Pack of 4 (Model 1218) charges the 1800mAh battery within 6-8 hours of direct sunlight — confirmed from the product specification. The 3W panel is the highest solar panel rating in the LumenCity solar wall light series, providing greater daily energy harvest than the 2W panels in the 3+3 and 6 Way models and matching the 3W panel in the 6+6 Model 1254. The compact 6.5 x 10 cm housing face accommodates the 3W panel in a slim, wall-flush installation profile visible in the product photograph. For Indian buyers installing the Pack of 4 on housing society compound boundary walls, south-facing wall positions maximise the daily 3W solar harvest across all seasons. In high-rainfall monsoon zones of Kerala, Karnataka, and the Western Ghats, the 3W panel provides greater daily energy harvest under diffused irradiance conditions than smaller panels, improving the reliability of full 1800mAh recharge on overcast monsoon days. Each of the 4 units has its own independent 3W panel and 1800mAh battery.
Installation & Wall Mounting – Pack of 4
The Solar Outdoor Wall Light Pack of 4 (Model 1218) installs on any outdoor wall surface without external wiring, underground cable, or mains power connection. Each unit wall mounts using standard masonry fixings — screws and wall plugs appropriate for Indian brick and concrete construction. The compact 6.5 x 10 x 2.5 cm housing is the smallest wall mount solar light in the LumenCity range, requiring minimal wall surface area and a low-profile 2.5 cm projection from the wall. Each unit is mounted with the solar panel face unobstructed for maximum daily charging, and the optically controlled sensor activated immediately from the first evening after the initial 6-8 hour charge. The Pack of 4 format is the correct procurement unit for the most common Indian installation scenarios: four compound boundary wall positions (one per wall section); two gate pillars with two lights each; four staircase riser positions; or a complete set of porch and entrance wall lights for a residential property. The off-grid design eliminates electrician engagement and ongoing electricity costs across all four installation positions. IP65 waterproofing on each unit ensures year-round performance without maintenance.
