How many lumens do you really need for home defense? When is it too bright?

I read a few days ago something about washing out your target with high lumen - narrow hot spot white light i.e. facial recognition. Any experiences or thoughts?

500 lumens inside had been great - especially if you need to illuminate a large room with vaulted ceilings, staircases, etc. You just have to make sure you use light discipline with one that bright.
