The old house is a bit dim, and the visibility is not good even during the day? Why not try this real "fluorescent lamp" below, which does not require any electricity or power generation equipment, just prepare a mineral water bottle~< /p>
Fill the bottle with water and put it on the roof. It will have a good lighting effect during the day. O(∩_∩)O Haha~ Remember to make sure it is waterproof~
