Load Data from EditorWindow to Prefab

So I’ve created a EditorWindow where I can input some variable to set some settings that will later be used by a script. I store away the variables using the EditorPrefs.SetFloat(). What I wonder is how I can retrieve the variable from the script later. Can I use EditorPrefs or do I need to use something else?

Here is the script for the settings window:

 class PowerUpSettings : EditorWindow 

{ #region Members

 bool showAttackRange   = false;
 bool showEffectRange   = false;
 bool showPushForce     = false;
 bool showTime          = false;

 //Attack Range
 float rangeMelee    = 1;
 float rangeShort    = 5;
 float rangeMedium   = 10;
 float rangeLong     = 15;
 float rangeVeryLong = 20;

 //Effect Range
 float effectSmall   = 1.5f;
 float effectMedium  = 3f;
 float effectBig     = 5f;

 //Push Force
 float pushShort     = 2;
 float pushMedium    = 4;
 float pushLong      = 6;

 //Time
 float timeVeryShort = 1f;
 float timeShort     = 2.5f;
 float timeMedium    = 5f;
 float timeLong      = 10f;
 float timeVeryLong  = 15f;

 #endregion
