The specularExponent attribute controls the focus for the light source. The bigger the value the brighter the light.
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="diffuseLighting1" x="0" y="0" width="100%" height="100%">
<feSpecularLighting in="SourceGraphic" specularExponent="1">
<fePointLight x="60" y="60" z="20" />
</feSpecularLighting>
</filter>
<filter id="diffuseLighting2" x="0" y="0" width="100%" height="100%">
<feSpecularLighting in="SourceGraphic" specularExponent="5">
<fePointLight x="60" y="60" z="20" />
</feSpecularLighting>
</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);" />
