How many foot candles is 1000 lumens?
How many foot candles is 1000 lumens?
How many foot candles is 1000 lumens?
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.
Can you convert foot candles to lumens?
One foot-candle equals 10.76 lumens (a lumen is considered the same as lux, which is what most modern light meters calculate their measurements in), so in order to convert your foot-candles to lumens, you will need to take the amount of foot-candles measured and multiply by 10.76 to get the number of lumens.
How many watts is 1000 foot candles?

How many foot candles is 2000 lumens?
20 footcandles
Lumens calculation summary For example, a 100-square foot living room, which needs 20 footcandles, will need 2,000 lumens.
How many lumens is a 10×10 room?
As a handy rule of thumb, a sitting room or bedroom will generally require around 10-20 lumens per square foot, while a bathroom or kitchen will need a stronger level of lighting, at around 70-80 lumens per square foot. To work out the lumens you need, simply multiply the square footage of the room by this figure.
At what distance are lumens measured?
In simple words, luminous flux tells how much light a lamp puts out in all directions per second, luminous flux is expressed in units called lumens (lm). Luminous flux only measures light radiated over visible wavelengths to a human eye from about 400-750 nm.
How many lumens is a candle?
12.57 lumens
Since the area of a sphere is 12.57 times the radius, it follows that one candle has the power of 12.57 lumens. It is important to remember that a lumen is like an energy source. When the lumens are directed onto or through an area, you get lumens per square foot or footcandles.
How do you calculate lumens of a light?
If one candela of luminous intensity is emitted evenly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen. That is, lumen depends on the surface that will be illuminated and the intensity of the light called lux. It follows that: lumen = lux x mq.
Is 1200 lumens too bright?
This type of light is no brighter than a 60 watt incandescent bulb. It is better for closets that do not have a lot of space. The brightest option for a room would be 1,200 lumens or more.
