Questions about gel nail polish

Hi,


So I know nothing about gel polishes, and I want to buy my first one. However I want to apply it at home but I know salons have special LED lights for drying. I was told that the gel polish I want to buy would dry with any LED light, even my phones flash. Is this true? Can it dry with any LED light? Can it dry with no light at all?
Please help.

I didn't find the right solution from the Internet.
