Black LED Solar Wall Light with Auto Sensor and 8 Hour Runtime

This black LED solar wall light provides a functional and energy-efficient method for illuminating exterior spaces. Designed to operate independently of mains electricity, it utilises a built-in solar panel to charge an internal battery during daylight hours. The unit features an automatic light control mechanism that detects ambient light levels, triggering the lamp to switch on at dusk and off at dawn. This functionality makes it a practical choice for enhancing safety and visibility around homes and commercial properties without incurring ongoing energy costs.

Technical Specifications

The core performance of this lighting unit is defined by its specific component ratings and physical dimensions.

Solar Panel and Battery

The system is driven by a 2V 0.25W solar panel, which captures solar energy to charge the included power storage unit. Inside the housing sits a 1.2V 1000mAh NiMH (Nickel-Metal Hydride) battery. This battery type is selected for its ability to handle repeated charging cycles from solar input, storing sufficient energy to power the lamp through the night.

Lamp Bead Configuration

Illumination is provided by 2835 specification lamp beads. These LEDs are chosen for their balance of brightness and energy efficiency, ensuring the stored battery power is utilised effectively. The 2835 designation refers to the physical package size of the LED chip, a standard industry specification that indicates the component's thermal and luminous characteristics.

Dimensions and Form Factor

The unit measures 75mm in width and 120mm in height. This compact footprint allows for installation in tighter spaces where larger fixtures might be obtrusive. The black finish provides a neutral aesthetic that blends with various architectural styles and garden furniture.

Operational Features

The primary operational benefit is the automated light control function.

Automatic Light Control

Equipped with a photosensitive sensor, the light requires no manual switching for daily operation. When the sensor detects that natural light levels have dropped below a certain threshold, typically at sunset, the circuit completes and the LEDs illuminate. Conversely, when morning light is detected, the unit switches off to conserve battery charge for the subsequent night.

Lighting Duration

Under normal operating conditions with a full charge, the light provides approximately 8 hours of illumination. This duration is designed to cover the typical hours of darkness throughout most of the year, ensuring the area remains lit until sunrise. Actual runtime may vary slightly based on seasonal sunlight exposure and battery condition.

Installation and Application

Proper placement is key to maximising the performance of any solar-powered device.

Optimal Placement

To ensure the 2V 0.25W solar panel receives adequate exposure, the light should be mounted on a wall or surface that faces south (in the northern hemisphere) or receives direct sunlight for a significant portion of the day. Avoid installing the unit under heavy shade, eaves, or behind obstacles that cast shadows on the panel, as this will reduce charging efficiency and subsequent runtime.

Suitable Environments

This 75mm x 120mm fixture is suitable for marking steps, lining driveways, highlighting garden features, or securing entry points. Its weather-resistant design intent allows it to withstand standard outdoor conditions, providing consistent performance in gardens, patios, and pathways.

Maintenance and Care

Maintaining the unit involves simple cleaning and periodic checks.

Cleaning the Panel

Dust, pollen, or bird droppings can accumulate on the solar panel surface, reducing its ability to absorb light. Wiping the panel gently with a damp cloth periodically will help maintain optimal charging speeds. Ensure the unit is dry before nightfall if cleaning during the day.

Battery Considerations

As with all rechargeable batteries, the capacity of the 1.2V 1000mAh NiMH cell may diminish over extended periods of use. If the lighting duration drops significantly despite good sunlight exposure, the battery may eventually require replacement to restore the original 8-hour performance level.
