What kind of lamp should I use to catch frogs?

Because it will be temporarily blind and can't see the surrounding situation clearly, it will definitely not make a move. In fact, not only frogs, but all nocturnal animals are temporarily blind under strong light, and can't see clearly until they are visually adapted. Hunters use this feature to illuminate animals at night and then shoot.

When we suddenly enter a very bright place in the dark (or turn on the light in the middle of the night), we will feel that our eyes can't be opened.
