		<div class="desc">
			Creates a visual aid for a [page:RectAreaLight].
		</div>

		<h3>Example</h3>

		<code>
var light = new THREE.RectAreaLight( 0xffffbb, 1.0, 5, 5 );

var helper = new THREE.RectAreaLightHelper( light );

scene.add( helper );
		</code>


		<h2>Constructor</h2>

		<h3>[name]( [page:HemisphereLight light] )</h3>
