Is there such a thing as a sun meter?

“This meter measures the duration and intensity of sunlight falling at a given spot over a 12-hour period.” It might measure these things but it does not report them. It only reports sun, part sun, part shade or shade. You get neither duration nor intensity readings.

Is 2 hours of sunlight enough?

Plant Sunlight Requirements

Medium light plants that grow in partial sun/shade only need three to four hours of direct sunlight, while plants that thrive in shade need only two hours of sunlight daily. For optimal plant growth, it is important to group plants with similar light requirements together in the garden.

How do you measure light?

(In the US it's common to express light intensity in unit of foot-candles. One foot-candle is equivalent to one lumen per square foot). Summarizing, while light output is expressed in lumens, light intensity is measured in terms of lumens per square meter or lux.

The luminous efficacy of direct sunlight rises with the solar altitude, going from 70 to 105 lumens per watt, and for diffuse skylight it ranges from 110 to 130 lm/W, for an overall global mean rate of around 105 lm/W.


How do you measure natural light in a room?

Determine the Needed Lumens A lumen is a unit measurement of light. To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens.

But there are three useful astrophotography tools in PhotoPills. A “Star Trails” calculator will show you how long star trails will be for a given exposure time.


    What is midday sunlight?

    Midday, especially during summer, is the best time to get sunlight. At noon, the sun is at its highest point, and its UVB rays are most intense. That means you need less time in the sun to make sufficient vitamin D ( 5 ). Many studies also show that the body is most efficient at making vitamin D at noon ( 6 , 7 ).
