create objects by script and fill them into array

hi all,

quite new to c# and struggling to create an array objects, I can use later on in my code. right now I'm doing this:

  public Light light0;
  public Light light1;
 
 void Start()
     { lightArr = new Light[]
         {
             light0,
             light1,
         };
 }
 void Update()
 {for (int i = 0; i < lightArr.Length; i++)
         {
             lightArr[i].transform.position = (new Vector3(UDPClient.lights[i * 3], UDPClient.lights[i * 3 + 1], UDPClient.lights[i * 3 + 2]));
         }
 }

I can generate those lightobjects by code, but I don't know how to fill them into an array like my old one. I want to update thier positions via UDP.

 for (int i = 0; i < 2; i++)
         {
             GameObject gObjekt = new GameObject("generatedLight" + i.ToString());
             Light gLight = gObjekt.AddComponent<Light>();
             gLight.color = Color.blue;
             gLight.transform.position = new Vector3(0, 0, 0);
             
 
         }

would appreciate some help on this :) and btw do you guys instantiate or generate? is it more practable to have this prototype you can modify or whats the reason?

thanks!
