For a super hand-wavy, ballpark answer, let’s say it’s a pine pole, 30 ft tall and 1 ft in diameter (0.5 ft radius). The volume of that pole is 30 * pi * 0.5^2, so 24 cubic feet. The density of pine is ~30 lbs per cubic foot, so this hypothetical pole weighs 30 * 24 = 720 pounds.
Why are LED street lights bad?
The first is discomfort and glare. Because LED light is so concentrated and has high blue content, it can cause severe glare, resulting in pupillary constriction in the eyes. Blue light scatters more in the human eye than the longer wavelengths of yellow and red, and sufficient levels can damage the retina.
