This tool converts lux to lumens to help you understand the light output needed for your space.
Lux to Lumens Calculator
How It Works
The Lux to Lumens calculator converts illuminance in lux to luminous flux in lumens. Illuminance (lux) is the amount of light that falls on a surface, while luminous flux (lumens) is the total amount of light emitted by a source. The calculation is straightforward:
Lumens = Lux x Area
You need to input the illuminance in lux and the area over which the light is spread in square meters. The calculator multiplies these two values to give you the luminous flux in lumens.
How To Use
- Enter the illuminance value in lux in the “Illuminance (Lux)” field.
- Enter the area over which the light is spread in square meters in the “Area (square meters)” field.
- Click the “Calculate” button.
- The result will be displayed in the “Result” field as lumens.
Limitations
While the calculator provides accurate conversion, it is based on the assumption that the light is uniformly distributed over the area. In real-world scenarios, light distribution can be affected by various factors such as obstacles, light sources positioning, and reflectivity of surfaces.
Use Cases for This Calculator
Calculate the Total Lumens Needed for a Room
Specify the dimensions of the room and the type of lighting you prefer, then use the calculator to determine the total lumens required to adequately light up the space. This will help you choose the right light fixtures for optimal brightness.
Compare Different Bulb Options for Brightness
Input the lux level you desire and compare the lumens output of different light bulbs to find the most suitable one. You can easily see how various bulbs stack up in terms of brightness and make an informed decision.
Determine Lumens for Task Lighting
Whether it’s for reading, cooking, or studying, input the required lux level for your task and calculate the corresponding lumens needed. This will ensure that your workspace is well-lit and conducive for the specific activity at hand.
Calculate Lumens for Outdoor Lighting
For your garden, pathway, or outdoor patio, enter the lux requirements to find out how many lumens you need for optimal outdoor lighting. Enhance the ambiance and safety of your outdoor spaces with the right amount of light.
Estimate Lumens for Artwork Illumination
Specify the lux level needed to highlight your art pieces and obtain the corresponding lumens output. This will assist you in choosing the appropriate lighting fixtures to showcase your artwork in its best light without causing damage.
Plan Lighting Design for Events
Input the lux requirements and determine the total lumens for event lighting, whether it’s a wedding, party, or corporate function. This will help you create the desired atmosphere and ensure that the venue is well-lit for the occasion.
Calculate Lumens per Square Foot
Enter the area of your room in square feet and the desired lux level to calculate the lumens required per square foot. This will give you a clear idea of how bright your lighting needs to be to illuminate the entire space effectively.
Adjust Lighting Intensity for Energy Efficiency
Experiment with different lux levels to see how they impact the total lumens needed for lighting. Find the right balance between brightness and energy efficiency by adjusting the intensity levels according to your preferences.
Verify Existing Lighting Setup
Input the current lux levels in your room along with the area size to calculate the total lumens provided by your existing lighting setup. This will help you identify any areas that might need additional lighting or adjustments for better illumination.
Ensure Proper Lighting for Plants
Enter the lux requirements for your indoor plants and calculate the necessary lumens for optimal growth and photosynthesis. This tool will assist you in providing the right amount of light to keep your plants healthy and thriving.
