It really depends on what you want to model. Time a of day, sunny weather ect.
I am going with led Par64 wash and spots dmx controlled. This will give me the ability to program a slow k shift from early morning to noon then sunset.
The spots will give single point source and a hard edge shadow like sunny days.
As a lighting designer when i was doing professional shows and the led technology first came out it would have been cost prohibitive but today consumer led stage lighting is so cheap the whole setup can be done almost for the price of a locomotive.
