Outdoor house illumination
(1/1)

Hi everyone, I'm new to the forum.
I need to light up a wall of an house at night, with one led floodlight.
How can I calculate the lumens needed in order fot that to work and nicely light up the wall?
Here is a quick sketch of the house: https://pasteboard.co/IWt9HrM.bmp (yellow-outlined area is the area i need to light up).
The wall is about 15m long, and the floodlight would be about 15m away from the house.
Is that possible or would it need a power so high that id doesn't even exist?
