External street Light plan for carpark showing areas of light

We are looking for a design to show the light dispersement of street lights in a private carpark.

Its an open space and we know roughly where the lights need to go but need something showing where the light will be shining in the dark to ensure we have enough lights.

Ive attached some info for you to look at. The first doc is a basic excel doc showing the site plan along with where we believe the lights need to go

second is a google pic of the site (its only carpark 1 and not 2 aswell)

third is the document for the lights themselves so you have the data needed on the power output etc.

Examples of similar projects would be great to show what we can expect
