The WOF-4xP7 flood puts out a huge amount of light, light an extremely bright 3000 lumen yard light, but will not throw the beam very far, perhaps good for 75 to 100 feet at most. Lights up a room like daylight, or your back yard, etc. Great for photography work, no hot spot, etc. The WOF-4xP7-4x27mm, using customized 27mm reflectors, has a beam that will light up objects easily at 100 yards and more, and still has tons of side spill. My poor photography does not come close to doing justice to what you actually see with your eyes.
