I have 2 of the 50 watt LED lights in the yard about 100 feet apart and 10' up, pointing to each other and there is plenty of light to do "stuff". I don't know that they make "daylight" out about 50 yards, but what he describes here is pretty close to what I've got.From my experience - these flood lights will make "daylight" out about 50 yards in front of your operation. Thereafter - diminishing out to about a quarter mile.
