  <filter id="diffuseLighting1" x="0" y="0" width="100%" height="100%">
    <feDiffuseLighting in="SourceGraphic" surfaceScale="1">
      <fePointLight x="60" y="60" z="20" />
    </feDiffuseLighting>
  </filter>
  <filter id="diffuseLighting2" x="0" y="0" width="100%" height="100%">
    <feDiffuseLighting in="SourceGraphic" surfaceScale="15">
      <fePointLight x="60" y="60" z="20" />
    </feDiffuseLighting>
  </filter>

  <rect x="0" y="0" width="200" height="200" style="filter: url(#diffuseLighting1);" />
  <rect x="0" y="0" width="200" height="200" style="filter: url(#diffuseLighting2); transform: translateX(220px);" />
