What is Lux in LED light?

Tony Black |

We use lux because it is an efficient measurement for determining what we see as the brightness of a beam. How can we calculate the number of lux? One lux is equal to one lumen per square meter here is the formula to get the value of lux: lux = lumens / m2 We need to determine what is a lux and how we can have the value of lux . Lux is a unit of measurement, which describes how much light falls on a certain area. (This is different from a unit of lumens, which tells you the total amount of light emitted by a light source.) The number of lux gets smaller as you get farther away from a light source. Sometimes we use the unit called “foot - candles”. Are there differences between lux and foot - candles? There is no difference between foot candles and lux in respect of what they measure. In the same way that feet, inches and metres both measure length, foot - candles and lux both measure the illuminance (the amount of light). The only difference would be the result of calculation because one foot - candle equals 10.764 lux and one lux equals 0.09 foot - candle. Why is different? It is different because lux uses meters and foot - candle uses feet.

You will need different amounts of lux or foot - candles for each space such as:
Supervisory work on machinery, equipment or products. Transportation or movement of materials. Location of heavy material. Here you will need 10 lux.
Common Reading or writing or word processing jobs or using computers or files or receipt of documents. Here you will need 300 lux. Servere or prolonged tasks with visual requirement to fine details, painting or detail work, work with small parts. Here you will need 750 lux. Hand crafting or manual work on tiny pieces or parts or tiny. Inspection or assembly or assembly of tiny or minute parts. Here you will need 1500 lux and for exceptional tasks difficult or with extraordinary visual requirement you will need 3000 depending the task.

Fortunately here at Hyperlite we are working with “lighting simulations” that will help you determine how many lights and the spacing for each light also these simulations will provide you the amount of lux or foot - candles, you can choose what unit you want to use.
