Spotlight plan mark
Plan mark for a directional spotlight, drawn as a luminaire with a beam arrow showing aiming direction.
In plain English
What does Spotlight plan mark mean?
Spotlights are drawn with a luminaire mark and a short arrow or beam lines showing aim. On retail and gallery plans the arrow tells the installer where to point the head on commissioning, saving a separate aiming schedule for simple projects.
A simple example
Spotlights may be on tracks, recessed adjustable housings or surface mounts. The tag identifies which, and the beam angle sets how tightly the light is concentrated. The arrow shows approximate aiming only, not tilt angle or beam spread.
What the drawings help you do
Follow the arrow for aiming direction. Check whether the spotlight is on a track. A floodlight spreads wide light over an area; a spotlight concentrates a narrow beam on an object.
