Candlepower and lumens are both measurements of light, but they measure different qualities of light. Convert candlepower to lumens by multiplying the amount of candlepower by 12.57. The resulting figure is the equivalent amount of lumens.Continue Reading
Candlepower, also known as candela, is the fundamental unit of photometry. Candlepower measures the amount of light produced at the source, which is light intensity. It does not account for the direction or quality of light beyond that. Lumens measure the amount of light at the object being illuminated. Lumens are technically complex units of measurement because they account for human sensitivity to total electromagnetic emission, but you can think of them simply as the total amount of visible light.
Determine the total amount of candlepower you wish to convert. That is the starting figure.
Multiply the starting figure by 12.57. The resulting answer is the number of lumens equivalent to the initial figure, the amount of candlepower. Now you know the amount of visible light that corresponds to a certain amount of emitted light. To convert in the opposite direction, divide the initial number of lumens by 12.57 to get the equivalent amount of candlepower.
To use a watts-to-lumens conversion table or calculator, such as those at RapidTables.com or MGE.com, find the type of light source on the table or calculator, and then find the lumens associated with the wattage rating for the light source. The brightness of a light source, often measured in lumens, depends on many factors including the light source's type, color and power rating, which is typically measured in watts.Full Answer >
A light's output in lumens can be found by checking the Lighting Facts label prominently displayed on the packaging of most lighting fixtures. If lacking a Lighting Facts label, the output of lumens can be determined through the use of a watts to lumens calculator.Full Answer >
In science, neutral means one of three things: something that is gray and without hue or zero chroma; something that does not have a charge and is not magnetized; or something that does not exhibit acid or alkaline qualities. Neutral has many meanings outside of science as well and can mean belong to a neutral state or party and not taking part or giving assistance during a dispute or war between others.Full Answer >
According to Energy Star, a standard 100-watt incandescent light bulb emits 1,600 lumens of visible light. The luminous efficacy of an incandescent light bulb is set at 16 lumens per 1 watt.Full Answer >
