There are focused ones as well at 8 degree beams angles, so that is pretty focused, still, they don't claim 300m. I have them, i would know. Mr. Singh has a flashlight that was good for 3 city blocks, but it was a $300 flashlight and the size of a canon.
All these light output ratings, 500, 1000, 10,000 is at the source of the light. When it's 20 feet away, it's a lot lower, at 300m (1050ft), like it said, it could be the moon. That flashlight was 5W. If it was a 5W laser beam flashlight, maybe.
