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 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. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.
How many lumens are in a foot?
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.
What is the difference between a lumen and a foot-candle?
Lumens are defined as a measure of the total amount of light emitted from a source. Foot-candles are the measured amount of light falling on a specific point or object.
How many candlepower are in a lumen?
Candlepower and lumens measure different light qualities, and 1 candlepower equals 12.57 lumens. When measuring lumens, you can also think of it as the light illuminated in a 1-square-foot area one foot away from a single candle.
How many foot-candles is low light?
Plants referred to as low light intensity plants generally should receive between 50 and 250 foot-candles. Under artificial light, a few plants in this group can be maintained at as little as 10 foot-candles. Low-light plants should receive between 10 and 15 watts of fluorescent light per square foot of growing space.
How many lumens is 100 square feet?
Lumens calculation summary Multiply your room square footage by the footcandle requirement. For example, a 100-square foot living room, which needs 20 footcandles, will need 2,000 lumens.
How many foot-candles is bright indirect light?
1000-2000 foot candles of light are considered bright indirect light.
How do you convert candlepower to lumens?
Candle power and lumens measure two different things, therefore it’s impossible to accurately convert between the two. However, you can get a good approximation with the following candle power to lumens formula: L=C/0.07958, where L is lumens and C is candle power.
How many candles equal a lumen?
Candlepower and lumens measure different light qualities, and 1 candlepower equals 12.57 lumens.
How many foot candles is bright indirect sunlight?
Bright indirect light is light that does not directly land on the leaves of your plant when sent from the sun. They land on something else first and then bounce off. 1000-2000 foot candles of light are considered bright indirect light.
How many lumens does a monstera need?
Grow lights work well for a Monstera Deliciosa. Make sure they are not too close to your plant and ensure that your Monstera gets sufficient light from the grow light. The light is often measured in lumen, lux, PAR or FC (foot candle). A good value to aim for is around 1000-2500 FC.
How many lumens is a candle?
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 are foot candles of light measured?
Picture a candle set in the middle of a sphere measuring 0.60 meters (2 feet) in diameter. If we cut a hole that measures 0.09 square meters (1 square foot) in the centre of this sphere, the light that shines through is what we define as a lumen. A foot-candle equals one lumen per square foot.
How many footcandles equal a lumen?
How many foot candles are in a lumen? 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.
The first thing that you need to do is use your light meter to measure the number of foot-candles that there are hitting the subject. Once you have this number, you can then use it to convert it into Lumens or Watts depending on what you want to do.
How do you convert lumens to foot candles?
– Understand the meaning of lumens and candlepower Candlepower, also known as candela, is the fundamental unit of photometry. – Start with the amount of candlepower Determine the total amount of candlepower you wish to convert. That is the starting figure. – Multiply by 12.57 Multiply the starting figure by 12.57.
