Question
Which statement about beam angles is NOT true?
Beam angle refers to the angle between the two planes of light where the light intensity is at least 50% of the maximum intensity at center beam.
Common beam angles range from 10 degrees (narrow) to 60 degrees (wide).
The average beam angle on most PAR lamps is 25 degrees and will work well for most purposes.
You need to know the beam angle of the lamp to calculate the spacing criterion.
Actually, all of the above statements about beam angles are true.
None of the above statements about beam angles are true.

The statement that is NOT true is:
"Actually, all of the above statements about beam angles are true."
This is because this statement is a catch-all that implies there are no inaccuracies in the earlier statements; however, not all of them may accurately reflect the characteristics of beam angles, depending on specific lighting context and definitions. Therefore, "None of the above statements about beam angles are true" is also incorrect, as some statements can be considered true, leading us to conclude that there could be inaccuracies in one or more of the previous statements.
