Lumen FX provides computer-aided calculations for both
indoor and outdoor lighting applications.

If there is a .CAD file of the space to be lit, we can import it into our system, vastly improving the speed and accuracy of the calc. In addition to the file, we will also need descriptive information per below. CAD files can uploaded to our FTP site by clicking here: UPLOAD SITE. Drag & drop your file into the folder, and let us know once you have uploaded the file, so we can pick it up.

A lighting calculation is a great tool to determine the number and type of fixtures required for a space, but as with any computer program, it is only as accurate as the information provided to the computer. Feel free to email or fax us your requests. Depending on our volume of requests, expect up to one week for the completion. To speed the process of getting an accurate calculation, we will need the following details:

INDOOR

    1. Room dimensions... Length   Width   Ceiling Height

    2. Ceiling type... Grid or open. Flat or sloped (if sloped provide side wall height and peak height). Any obstructions that migh affect lighting.

    3. Fixture mounting height. This is the measurement from the bottom of the fixture to the floor.

    4. Desired lighting levels in footcandles. If unknown, please accurately describe the activity taking place in the space and we will make a recommendation.

    5. Reflectances of the ceiling, walls and floor. If unknown, please provide the color finishes and flooring covering. 

    6. Fixture type you would like to use.

    7. Desired light source. (Metal Halide, Fluorescent, etc)

    8. Project name.

    10. Your company info.

    OUTDOOR

      1. Area dimensions.

      2. Drawing of the area (even if very rough) to help us understand what it looks like.

      3. Code limitations. (Cutoff / Pole Height etc.)

      4. Pole location limitations. (Show us where poles can be located and where they cannot).

      5. Tree locations.

      6. Desired lighting levels in footcandles. If unknown, please accurately describe the activity taking place in the area and we will make a recommendation.

      7. Are the lighting levels to be average or minimum.

      8. Fixture type you would like to use.

      9. Desired light source. (Metal Halide, High Pressure Sodium, etc)

      10. Project name.

      11. Is there an architect or engineer involved?

      12. Your company info.
