Williams Quantity Estimator & Layout Calculator

Use this calculator to find out how many Williams light fixtures are needed to achieve given light levels for a simple, rectilinear room. This calculator does NOT give comprehensive point-by-point data.

  1. Go to any section in the Product Catalog.
  2. Click on the Quantity Estimator link in the right hand margin of a selected product. Some products (e.g. Emergency/Exit) do not have a calculator.
  3. Wait while the Estimator loads. This can take a few seconds.
  4. Select from the Luminaire pull-down list to begin your calculations.
  5. When you want to print out a report, click the Print button in the Lower-Right corner of the estimator.

For point-by-point calculations or more complicated layouts, contact your H. E. Williams, Inc. Agent.
