Outdoor Solar Wall Lights

1. Measured in Lumens
The brightness of any light—including solar wall lights—is measured in lumens (lm), not watts.

Low-output solar wall lights typically range between 20–100 lumens, suitable for decorative purposes or ambient lighting along fences or garden walls.

Medium-output models offer 100–300 lumens, which is bright enough for porches, patios, or general entryway lighting.

High-performance solar wall lights, especially those designed for security or with motion sensors, can produce 400–1,000 lumens or more, comparable to a small mains-powered floodlight.

2. Factors That Affect Brightness
Panel Efficiency: Higher quality solar panels charge better and power brighter LEDs.

Battery Capacity: A larger battery (e.g., 2,000 mAh or more) supports stronger and longer-lasting light output.

LED Technology: Newer models often use SMD or COB LEDs, which are brighter and more efficient than older LEDs.

Motion Sensors: Many lights operate in dim mode until motion is detected, then temporarily switch to full brightness to conserve battery.

3. Practical Application Examples
40–100 lumens: Ideal for decorative ambiance—e.g., along a garden fence or flower bed.

150–300 lumens: Suited for illuminating entryways, garden paths, or garages.

400+ lumens: Excellent for security purposes or when strong visibility is needed, such as in dark alleyways or driveways.

1.Yes—artificial lighting can prevent them from turning on at night.

Install them away from other light sources like streetlamps.

2.You can test by covering the solar panel—if the light comes on, nearby light may be an issue.

1.Yes, but efficiency is reduced due to weaker sunlight and shorter days.

2.They still charge on cloudy days, but more slowly.

3.Positioning the panel in a sunny, south-facing spot maximises performance.
