Required Lumens and Watts

Calculate Perfect Lighting: Lumens and Watts Tailored to Your Space
Creating the perfect ambiance in your home starts with the right lighting. However, choosing the right bulbs with the right power can be confusing. Our app makes your life easier
We take everything into account:
Room Size: Simply enter the dimensions of your room (square meter) into the app.


Space Type: Is it a retail, bedroom, living room, or office? Choosing the space type helps our app recommend optimal lighting levels.
Behind the scenes, our app uses common average lux (unit of illumination) and lumens-per-watt (a measure of energy efficiency) values based on typical fixture types and light source combinations. This helps us recommend appropriate lumen and wattage. Keep in mind that actual lumens needed may vary slightly due to factors like wall color, furniture types, and personal preferences.
Disclaimer: Our app uses common average lux and lumens-per-watt values based on typical lighting fixture types and light source combinations to calculate recommended lumens and watts. Actual lumens and watts needed may vary due to factors like specific fixture design, reflector materials, and variations in light source output. Please note: The calculations and data provided in this app are approximate and for general informational purposes only. For precise lighting requirements and recommendations, we advise consulting with a lighting expert or professional electrician. Factors such as light losses, degradation over time, room architecture, number of windows, and wall colors can significantly impact lighting needs and performance. This calculation is based on our experience in selling electrical equipment and may not account for all individual circumstances.
The goal of this application is to attempt to calculate the required lumens and watts. It does so by using commonly taken average values for lux levels of space types and lumens per watt for the light type, along with user input of the size of the specific space. Calculations in some cases may be very close to actual and realistic data. However, because the application only utilizes some of the data for calculation, we advise you not to take these results as accurate.
