Mounting Height
The user can change the mounting height (ft. or m) in the MH text box by using the up and down arrow keys on the keyboard or by manually entering a value. The arrow keys increment and decrement the mounting height according to the current snap setting. Once the Locate button has been depressed, you may change the mounting height for subsequent luminaires by using the arrow keys or entering a new mounting height.
Mounting height corresponds to the symbol insertion point. This is not necessarily analogous to the location of the Photometric center. Please reference the following topics.
