How can I make sure that mobs don't spawn?

I play minecraft and wanted to ask if it is enough if I place torches outside of my house so that no mobs spawn and is that also possible with soul lanterns?

If you press F3 you will also see a light value, this should be> 10 and then no more monsters will spawn there. As far as I know, it makes no difference where the light source comes from.

Yes that is enough. The main thing is that it is bright.

You can use any kind of light source, including sea lanterns.

> 7 as far as I know

You can also just put slaps. Monsters don't spawn on half a block

Everything that makes light prevents mobs from spawning, and you don't have to place a torch on every block, but only every four to five blocks as far as I know

But I prefer to use steps so I build my whole floor full of steps and this is how I prevent mobs from spawning

But a little bit of light doesn't do any harm (I just set my brightness so high that I don't need any torches
