Smarter Sensor Modes
Mpow Solar Motion Sensor Light now has Three Intelligent Modes for your choice.
1.Strong Long Light Mode: When it fades into darkness, the light will keep strong and bright until the environment becomes bright.
2.Dim Light Sensor Mode: When in dark night, the light will be dim without people coming near. If people comes, it will brighten up, and the bright light will last 15 seconds until it returns to dim light again.
3.Strong Light Sensor Mode: In night, the light will be strong bright when people comes, and then 15 seconds later, the light dies out automatically.
Brighter Lights Last Longer
This Mpow light is now equipped with 20 bigger LED lights, which is far more brighter than other similar LED lights in the market. And what’s more, we increase the battery capacity from 600mAh to 1500mAh, thus getting some two more hours’ duration.
Better Sensor Ballhead
When received this Mpow Solar LED Light, you will find distinct difference compared to its previous version or similar lights in the market, We update the PIR motion sensor and ray sensor, so it becomes more powerful that it can detect people’s coming within 26 feet!
Phenomenal Overall Quality
To improve the waterproof level, we now add two layers, tightly sealed inner loop to its back case, hence, this Mpow light becomes more durable and weatherproof. And we have also updated the solar panel, thus getting a high-efficient, frosted, anti-scratch solar panel.
