		<h1>[name]</h1>

		<div class="desc">This illuminates the scene from a complete surface. This light only works in the [page:WebGLDeferredRenderer deferredrenderer]. </div>


		<h2>Example</h2>
		<code>areaLight1 = new THREE.AreaLight( 0xffffff, 1 );
areaLight1.position.set( 0.0001, 10.0001, -18.5001 );
areaLight1.rotation.set( -0.74719, 0.0001, 0.0001 );
areaLight1.width = 10;
areaLight1.height = 1;

scene.add( areaLight1 );</code>

		<h2>Constructor</h2>


		<h3>[name]( [page:Integer hex], [page:Float intensity])</h3>
		<div>
		[page:Integer hex] — Numeric value of the RGB component of the color.<br />
		[page:Float intensity] — Numeric value of the light's strength/intensity.
		</div>
		<div>
		This creates a arealight with color.
		</div>


		<h2>Properties</h2>


		<h3>.[page:Vector3 right]</h3>
		<div>
		Sets or gets an unit vector that indicates the right side of the light. This is calculated in local space. 
		</div> 

		<h3>.[page:Vector3 normal]</h3>
		<div>
		Sets or gets an unit vectorSets or gets an unit vector that indicates the right side of the light. This is calculated in local space.
		</div> 

		<h3>.[page:number height]</h3>
		<div>
		Sets or gets the height of the illuminating plane. 
		</div> 

		<h3>.[page:number width]</h3>
		<div>
		Sets or gets the width of the illuminating plane. 
		</div> 

		<h3>.[page:Float intensity]</h3>
		<div>
		Light's intensity.<br />
		Default — *1.0*.
		</div>

		<h3>.[page:number constantAttenuation]</h3>
		<div>
		Sets or gets the attention of the light in constant space. This is independant of the distance of the light. 
		</div> 

		<h3>.[page:number linearAttenuation]</h3>
		<div>
		Sets or gets the attention of the light in linear space. This increases the attenuation linearly with the distance from the light.
		</div> 

		<h3>.[page:number quadraticAttenuation]</h3>
		<div>
		Sets or gets the attention of the light in linear space. This increases the attenuation quadratic with the distance from the light.
		</div>
