How bright will your space be after you convert to LED Lighting? That’s a great question. No one wants to spend money on a LED lighting conversion project only to find out the room isn’t bright enough. Or too bright. Saving money is one thing. Ending up with the right results is as important when upgrading to LED lights.
So, how can you make sure the light you choose will be the right choice? How many watts? How many lumens? What optics should you use? It’s hard to look at a cut sheet and determine that this is the perfect light for the job.
To use this calculator, enter the following:
- Length, Width and Height of room in feet
- Lumen output of the fixture you want to test
- The desired foot candles of the fixture
What it will return:
The approximate number of fixture you will need to get the required foot candle levels.
Please note: this is a lighting layout approximation tool. It should never be used in place of a lighting plan or photometric design. The basic tool we provide will not visually show how good the distribution is, light placement, what optic you may have to use or the avg/min foot candle ratios.

Lighting Calculations – Photometrics
Lighting Calculations gives you a virtual representation of what the lighting could be. Using lighting software, it models the dimension of your room including:
- ceiling, wall and floor reflectivity
- natural light
- existing light locations
- perception of the current light (too bright, too dark, just right)
- the existing fixtures
Using this information, we model the interior space utilizing different light fixtures, configurations and optics. When we perform the modeling, we observe the light levels at the floor or desired work plane, and how well the light is distributed. We run several models with different fixtures, calculating what the best option and results will be for you.
Lighting calculations can model any option. If you have high ceilings, you may consider a lower angle optic to put the light on the ground and less on the walls. If you have lower ceilings, we would choose a fixture with greater beam distribution to level out the light levels across the entire areas.
Example: Warehouse space 200 ft long, 100 ft wide, 35 ft high with a goal of 30 foot candles
The photometric shows 4 rows of 9 150W LED UFO needed to achieve 30 fc with uniform light distribution.
150W LED UFO High Bay (42 fixtures)
So by doing a simple lighting calculation, you can see what your space can look like before you even spend 1 dollar. We can assist you in determining the option with the best light distribution for your need.
We strongly believe that performing an interior lighting calculation before you purchase greatly reduces the risk of buying the wrong fixture.
