* Lumens must be multiplied by ballast factor (BF) to get estimated lumen output per lamp. Also, lumen
depreciation is generally in the range of 5 to 30%, and should be considered in the actual lighting design.
** This is a rough estimate only. There is a tremendous range of performance based on manufacturer, age
of lamp, lumen output, type of ballast, ballast factor, CRI, etc. Actual figures should be obtained directly
from manufacturer for a proper calculation. Note that fixture watts change as ballast factor (BF) changes.
