How do you calculate foot-candles?
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. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.

How many foot-candles is a full moon?
How many foot-candles of light does a full moon produce? Full daylight typically equals about 1,000 foot-candles, while an overcast day would have only 100 foot-candles of light.

How do you calculate lighting requirements for a shop?
Start by measuring your space and multiply the length by the width to get your square footage. Then multiply your square footage by 70 to get the minimum lumen requirement for your workshop. For example, my shop is 12′ x 16′ = 192 square feet. I would require a minimum of 192 x 70 = 13,440 lumens.
How many foot-candles is full sun?
Over 5000 footcandles–nearly full sun except at midday, when full summer sun in most latitudes may reach 10,000 fc. Full sunlight through clean fiberglass is usually 5000-7000 fc on a clear day.
How many foot-candles are in a 100 watt bulb?
Their efficiency is in the range of 4 lumens per watt. This means that a 100 watt bulb will generate 400 lumens – TOTAL. (Here’s the big leap) Now, if we COULD reflect all of that 400 lumens onto 1 square foot we would get a light intensity of 400 foot candles.
