This is a huge solar-powered LED night light that is put down during the day to collect sunlight and convert it into electrical energy for storage. When it is turned over at night, the LED light will turn on and the stored energy can be used for a whole night.
The advantage is that the LED is very time-consuming to use. The disadvantage is that it is relatively easy to attract small flying insects.
