FAQ:
How many lumens is a street lamp?
From what I have read low pressure sodium puts out approx 180 lumens/watt so a 100 watt bulb would be 1800 lumens, a 400 watt bulb would be around 72,000 lumens using that figure
What wattage are LED street lights?
Some LED street lights require only 73 watts and, according to the U. S. Department of Energy, produce a higher quality of light. Fluorescent bulbs were used in street lights from the 1950s to the 1970s, but because of their low reliability and size, they gave way to high-pressure sodium lights rated at 250 watts.
How long do LED Street Lights last?
An LED light can last 100,000 hours [source: Rosenthal and Barringer]. These lightsalso have reduced maintenance costs because of their long lives, and they give off less heat than other bulbs.
