When it comes to lighting, candlepower and lumens are two of the most important elements. Candlepower or candle foot-candle (fc) is a measure of the intensity of light, while lumens (lm) measure the total amount of visible light emitted from a source. In other words, lumens measure the total ‘brightness’ of a light source, while candlepower measures the intensity of light at a point. It is important to understand the difference between candlepower and lumens in order to determine how much light is being emitted from a source.
To put it simply, one lumen is the amount of light emitted from a single candle of one foot-candle brightness. This means that one lumen is equal to one foot-candle. Therefore, one thousand lumens is equal to one thousand foot-candles, or one thousand candlepower.
What is a Candlepower?
A candlepower is a measure of the intensity of light at a given point. It is measured in candelas or foot-candles (fc). A foot-candle is equal to one lumen per square foot. A candlepower is a unit of measurement that is used to measure the intensity of light. It is the amount of light emitted from a single candle at a distance of one foot.
The candlepower of a light source is usually expressed in lumens per square foot or candelas per square foot. The higher the number, the brighter the light source. For example, a 100 watt bulb will typically have a candlepower of 1000 lumens per square foot.
How to Calculate Lumens to Candlepower?
To calculate lumens to candlepower, you need to know the distance of the light source from the point where the candlepower is being measured. This is because the intensity of light decreases over distance. You then multiply the lumens by the distance in feet, and this will give you the candlepower.
For example, if you have a light source of 1000 lumens, and the distance from the point where you are measuring the candlepower is 10 feet, then the candlepower is 10,000 (1000 x 10).
What is the Difference Between Candlepower and Lumens?
The main difference between candlepower and lumens is that candlepower measures the intensity of light at a point, while lumens measure the total amount of visible light emitted from a source. Candlepower is measured in candelas or foot-candles (fc), while lumens are measured in lumens per square foot.
Candlepower is a more precise measurement of light intensity than lumens because it takes into account the distance from the source. Lumens measure the total amount of visible light emitted from a source regardless of distance.
What is the Brightness of 1000 Lumens?
The brightness of 1000 lumens is equal to one thousand foot-candles or one thousand candlepower. This means that 1000 lumens is equal to one thousand foot-candles of light intensity.
The brightness of 1000 lumens is equal to that of a 100 watt light bulb that is placed one foot away from the point where the light is being measured. At this distance, the light intensity is 1000 lumens or one thousand foot-candles of light.
Conclusion
In conclusion, 1000 lumens is equal to one thousand foot-candles of light intensity, or one thousand candlepower. Candlepower is a measure of the intensity of light at a given point, while lumens measure the total amount of visible light emitted from a source. It is important to understand the difference between candlepower and lumens in order to determine how much light is being emitted from a source.
