![]() Be careful when making a comparison between two lamps. Lux can be measured from different distances. The number of lux is thus found as the quotient of the total received luminous flux, expressed in lumens, and the size of the illuminated area expressed in square meters therefore 1 lux = 1 lumen / m². The lux thus corresponds to the illuminance that is obtained when each square meter of the considered surface receives a luminous flux of one lumen. The lux (symbol lx), latin for light, is a unit of illumination: 1 lux is the illuminance produced by 1 candela on a surface perpendicular to the light rays at a distance of 1 meter from the source. The smaller the angle of radiation in which the light is emitted, the higher the luminous intensity (with constant luminous flux). An incandescent lamp gives a luminous flux of approximately 12 lm / W. The luminous flux depends on the power of the source and on the color of the light. If one sees a part of a light beam, that part has a smaller luminous flux (in lumen) but (in principle) the same luminous intensity (in candela) as the whole beam. Light intensity is a measure of the light density. Luminous flux is a measure of the total amount of light in a light beam. Lumen is therefore the unit to measure the brightness of a light source independently of the direction of the light beam. Luminous flux takes into account the sensitivity of the eye to the visible part of the electromagnetic radiation. ![]() It measures the total amount of light emitted by a light source in all directions. ![]() It does not store any personal data.The lumen (symbol: lm) is the unit for luminous flux.

P (W) = Фv (lm) / η (lm/W), which means that the power in watts is calculated by dividing the luminous flux in lumens by the luminous efficacy in lumens per watt. This calculator uses a particular formula in executing the conversions. The power result in watts will be displayed as The luminous efficacy in lumens per watts is automatically determined by the calculator as it is displayed in the text field.Ĭlick the ‘Calculate’ button to perform the calculation. The first step is to enter 5000 as the value of the luminous flux in lumens and select fluorescent lamp as the light source. If a fluorescent lamp has 5000 luminous flux in lumens, calculate the power in watts. The power result in watts will be displayed in the bottom platform of the calculator below the two controls. If you want to perform new conversions, the ‘Reset’ button will be useful in erasing all data of the previous calculations from the text field. Confirm that you have entered the appropriate values in the required text field and then click on the ‘Calculate’ button to execute the conversion. Afterwards, you can select the light source or enter the luminous efficacy in lumens per watt. The initial step is to enter the value of luminous flux in lumens. It has two controls, the ‘Calculate’ and ‘Reset’ buttons which perform different functions of the calculator. It delivers accurate results based on the values entered in the text fields which makes it an effective calculator in performing the conversions. It is a conversion calculator that is used to convert the luminous flux in lumens (lm) to the electric power in watts (W). What is a Blog and Why Do You Need One to Make Money Online from Your blog.
