Floodlight plan mark
Plan mark for a floodlight that lights an area, drawn as a luminaire with a widening beam.
In plain English
What does Floodlight plan mark mean?
Floodlights for yards, sports areas, facades and car parks are drawn as a luminaire mark with diverging beam lines, showing a wide spread. The aiming direction is shown by the beam and mounting height is noted.
A simple example
Floodlights are typically controlled by a photocell, time switch or contactor because the load is large. The plan symbol often sits on a building wall or a pole and is linked to that control scheme. Beam lines are indicative. Photometric calculations, not the symbol, confirm coverage.
What the drawings help you do
Note aiming direction and mounting height. Find the control scheme. A spotlight has a single narrow beam arrow; a floodlight shows a diverging beam.
