Lumen is among the four basic terms that are used to describe light and how it affects us, the others are Foot-Candle, Watt, and Lumens per Watt. It is the measurement of light available at a given distance.
How many lumens is the sun on earth
The general “rule of thumb” I use is between 1 and 1, 000, 000, 000 per square foot, however the sun output is affected by the weather condition, the area the sun is exposed to and time of the day.
To calculate the amount of sunlight reaching the ground, both Earth’s elliptical orbit and the attenuation by Earth’s atmosphere have to be taken into account
Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux. This is higher than the efficacy (of source) of most artificial lighting (including fluorescent).
Multiplying the figure of 1050 watts per square metre by 93 lumens per watt indicates that bright sunlight provides an illuminance of approximately 98 000 lux (approximately 10, 000 lumens per square foot.). To better illustrate it – about 100, 000 Lumen chandelier is like having the sun a few feet above your head.
How many lumens is the sun during Summer
During summer, Sun daylight is about 10, 000 foot candles. This is equal to 10, 000 lumens per square foot. This output is equivalent to about a thousand watt metal halide bulb.
How many lumens is the sun during an eclipse
am waiting to hear from you….. how many lumens do you think the sun produces during a full eclipes? please comment below
How many lumens is the sun during an overcast day
During an overcast day, the amount of lumens that the sun produces drops to about 1, 000.
how many lumens is the sun per square foot
How many lumens is the moon
under the light of a full moon you would be subjected to .02 foot candles.
