EDC = Flood mostly.
If you burst into a dark warehouse, and want to know if someone ELSE is in there...a flood lights the place up like you flipped on a light switch, and you can see the entire space at once.
If you have a tight beamed light, you have to sweep it methodically across the entire potential space a few feet at a time, like looking at the room through a long paper towel tube a little at a time, and then trying to stitch together your views to take it all in.
The OTHER guy of course sees you, and, can even see your little circle of light sweeping across the room, and has plenty of time to duck and hide when the when its finally time for the beam to sweep HIS position, etc...."Here it comes - DUCK!"
If they want to shoot you, or run for it...they know when the best time is, because they KNOW WHERE YOU ARE LOOKING at any given moment.
If you are doing a search over a long distance, like a large hillside, etc...there are no floods that light up several acres at a time...you need a search light, and you DO need to sweep methodically back and forth to cover the areas of concern with a tighter pattern, as that's the only practical way to get enough lux on a target far away....to tell what you are looking at.
A strong floody beam might be able to tell you there's a guy standing 200 yards away with something in his arms....but maybe not really give enough light on the target to tell if its firewood or firearm...whereas the dedicated thrower might tell you that....
...If he lets you CATCH HIM in that spot light beam, etc.
