Video of a 1 watt green (520nm) laser and a 7 watt blue (450nm) pointed toward an iPhone from about 1.25 miles away. - JetLasers PL-E mini - 1 watt 520nm - Zeus X - 7 watt 450nm
The 7W is a tad more distinct.. but also fascinating to see the difference from a distance, as when you standing with them, you feel like you have a ducking lightsaber in hand that could cut the moon in two, at will.
