The lux to lumens calculator will help you choose the illumination solution that best meets the specific requirements of your application. We offer a number of high-quality, energy-efficient LED strips and modules that can be used to solve a diverse range of lighting applications. Providing the right amount of light for a task can have a significant impact on efficiency, productivity and safety. The amount of light needed to properly illuminate a task or process can vary depending on the application.

Lux to lumens conversion

In the world of flashlights and headlamps, lumen is king. It is the number one most heavily marketed specification and the first thing people look for when choosing a flashlight or headlamp. But it is not the only unit that can be used to describe how bright a light is. Most models have different lumen levels, so pick the one you use regularly or try with the different levels. Be aware that some lights have a focusing system, so you can try with both the wide angle beam and the spot beam. Lumen lm is the total amount of light emitted from a flashlight or headlamp, so the more lumen a light has the brighter it is — roughly. Lumen is measured in a closed sphere that captures all the light emitted from the light source, but it does not take the optics into account. This is why the number of lumen not necessarily corresponds to how bright the light appears in reality. And this is where lux comes into the picture. Lux lx is also a unit used to measure light but unlike lumen, lux takes area into account. Lux is used to determine the intensity of the light over an illuminated area, to be specific; 1 lux equals 1 lumen pr. A flashlight or headlamp cannot be marketed with a specific amount of lux, because it depends on how far away the light source is and the angle of the light beam. Lux can be measured using a lux meter.

Lumen is measured in a closed sphere that captures all the light emitted from the light source, but it does not take the optics into account, lux to lumens conversion. The superior electronics often produce more of the shortcomings described below compared to the cameras with superior optics.

Lux to Lumens Calculator. Lux to Lumens calculator It is a conversion calculator that converts the illuminance in lux lx to luminous flux in lumens lm. It has three text fields and two controls that perform independent functions of the calculator. The initial step is to enter the value of illuminance in lux. Select the unit type either area in square feet or area in square meters. Proceed to the next text fields where you can either enter the spherical radius or the surface area. The luminous flux result in lumens will be displayed below the two controls in the bottom platform of the calculator. For example; If the illuminance is lx and the spherical radius is 16 feet, determine the luminous flux result in lumen. Solution; If you are using the calculator, you will first enter in the illuminance in lux text field. Select the unit type as area in square feet and enter 16 as the spherical radius.

Enter the illuminance in lux lx , select area unit type, enter radius in meters for spherical light source or surface area. Candela to lumens Lumens are now the most common measurement for a light bulb. The lumen lm is a measurement of luminous flux, or the total amount of visible light. To put it simply, the lumen rating is how much total visible light is produced by a light source. For a bulb emitting 1 cd, that bulb would also have a luminous intensity of Obscuring half the bulb making it a hemisphere instead of a full sphere , a 1 cd bulb will emit only 6. This is because lumens measure the total amount of visible light from a light source. So why all of the different ratings?

On the other hand, a lamp of the same brightness with a small beam angle or short distance has a larger lux value. Cancel Continue Shopping. More information about the exposure value. The definition of the exposure value EV ignores the units of the denominator and uses only the numerical value of the exposure time in seconds. You can use this online converter to convert between several hundred units including metric, British and American in 76 categories, or several thousand pairs including acceleration, area, electrical, energy, force, length, light, mass, mass flow, density, specific volume, power, pressure, stress, temperature, time, torque, velocity, viscosity, volume and capacity, volume flow, and more. Note: Integers numbers without a decimal period or exponent notation are considered accurate up to 15 digits and the maximum number of digits after the decimal point is In addition, a camera will have either one chip to process the light that is coming in, or three — one for each color red, green, and blue. Units One of the most common units for measuring Illuminance is a lux. We could also think of the area as being bright, or the object as being bright, or the light source as being bright. More info

NOTE: Converting between geometry-based measurement units is difficult and should only be attempted when it is impossible to measure in the actual desired units. You must be aware of what each measurement geometry implicitly assumes before conversion.

The larger the area illuminated by a given light source, the more dimly this area will be lit by this light source. On the other hand, a shiny white car can be perceived as relatively bright even though the absolute amount of light that falls onto its surface can be even smaller than that on a surface covered with black velvet. This can be considered as light intensity within a certain range. Some cameras work better in low light than others — camera manufacturers sell cameras designed for these conditions.

Flashlights and headlamps from different brands are constructed very differently which reflects in how efficiently they perform. Compact Calculator Full Calculator Unit definitions. This formula is used in the illuminance converter to convert EV to lx and vice versa. On the other hand, the brightness of your LED light fixture is usually expressed in lumens. It is generally used to determine whether the lighting in the area is problematic and needs more testing, not for final testing.
