how much light does the sun give off
Sunlight 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 (lumens per square meter) on a perpendicular surface at sea level. The illumination of a horizontal surface will be considerably less than this if the Sun is not very high in the sky. Averaged over a day, the highest amount of sunlight on a horizontal surface occurs in January at the South Pole (see insolation).
I Won't Let the Sun Go Down on Me "I Won't Let the Sun Go Down on Me" is a song written and performed by the English singer-songwriter Nik Kershaw. It was his first single, released in 1983 to little success, but was re-released in 1984 and became his highest charting hit, peaking at no. 2 in the UK. The song was included on Kershaw's debut album Human Racing.
