Disclaimer: Calculations are provided using industry recognized software and are provided for estimation purposes only. Input data for the calculations corresponds to the information provided to us (assumptions may be made for information that is not provided). It is the responsibility of those using this service to verify that our input data is consistent with expected field conditions. Results of the lighting calculations accurately reflect the input data. However, actual lighting levels will vary depending on field conditions such as room characteristics, temperature, voltage, and lamp/ballast output and other factors. Calculations are also subject to the limitations of the software. Due to the above considerations, Penn Lighting Associates cannot guarantee that actual light levels measured in the field will match our initial calculations.
