I have 2 standard issue flood lights with the 2 bulbs and love them. They lit up the old pool that was 75 ft away.There is only the light fixture at our back door currently.
One (double) might be enough but they don't do so well when facing opposite directions and it would be easy enough to stagger a 2nd one a few feet over.

I have the 3 way LED one in the driveway and it is uncomfortably bright close to the house but doesn't go very far.
