The pointsAtX attribute represents the x location in the coordinate system established by attribute primitiveUnits on the <filter> element of the point at which the light source is pointing.
You can use this attribute with the following SVG elements:
Example
<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
  <filter id="lighting1" x="0" y="0" width="100%" height="100%">
    <feDiffuseLighting in="SourceGraphic">
      <feSpotLight x="60" y="60" z="50" pointsAtX="0" />
    </feDiffuseLighting>
  </filter>
  <filter id="lighting2" x="0" y="0" width="100%" height="100%">
    <feDiffuseLighting in="SourceGraphic">
      <feSpotLight x="60" y="60" z="50" pointsAtX="400" />
    </feDiffuseLighting>
  </filter>
  <rect x="0" y="0" width="200" height="200" style="filter: url(#lighting1);" />
  <rect x="0" y="0" width="200" height="200" style="filter: url(#lighting2); transform: translateX(220px);" />
</svg>
