+			This light gets emitted uniformly across the face a rectangular plane. This can be
 
+			used to simulate things like bright windows or strip lighting.<br /><br />
 
+
 
+			This light can cast shadows - see the [page:RectAreaLightShadow] page for details.<br /><br />
 
+
 
+			<em>NOTE:</em> this class is currently under active development and is probably not
 
+			production ready yet (as of r83). Check back in a month or two! And feel free to try it out in the meantime.

+
 
+		<h3>[name]( [page:Integer color], [page:Float intensity], [page:Float distance], [page:Radians angle], [page:Float penumbra], [page:Float decay] )</h3>
 
+		<div>
 
+			[page:Integer color] - (optional) hexadecimal color of the light. Default is 0xffffff (white).<br />
 
+			[page:Float intensity] - (optional) numeric value of the light's strength/intensity. Default is 1.<br /><br />
 
+			[page:Float width] - (optional) width of the light. Default is 10.<br />
 
+			[page:Float height] - (optional) height of the light. Default is 10.
 
+
 
+			Creates a new [name].
 
+		</div>
 
+
 
+		<h2>Properties</h2>
 
+		<div>
 
+			See the base [page:Light Light] class for common properties.
 
+		</div>
 
+
 
+
 
+		<h3>[property:Boolean castShadow]</h3>
 
+		<div>
 
+			If set to *true* light will cast dynamic shadows. *Warning*: This is expensive and
 
+			requires tweaking to get shadows looking right. See the [page:RectAreaLightShadow] for details.
 
+			The default is *false*.<br /><br />
 
+
 
+			<em>Note:</em> this is not yet implemented for this light type! (r83)
 
+		</div>
 
+
 
+		<h3>[property:Float decay]</h3>
 
+		<div>
 
+			The amount the light dims along the distance of the light.<br />
 
+			In [page:WebGLRenderer.physicallyCorrectLights physically correct] mode, decay = 2 leads to
 
+			physically realistic light falloff. The default is *1*.<br /><br />
 
+
 
+			<em>Note:</em> this is not yet implemented for this light type! (r83)
 
+		</div>
 
+
 
+		<h3>[property:Float distance]</h3>
 
+		<div>
 
+			If non-zero, light will attenuate linearly from maximum intensity at the light's
 
+			position down to zero at this distance from the light. Default is *0.0*.<br /><br />
 
+
 
+			<em>Note:</em> this is not yet implemented for this light type! (r83)
 
+		</div>
 
+
 
+		<h3>[property:Boolean isRectAreaLight]</h3>
 
+		<div>
 
+			Used to check whether this or derived classes are spot lights. Default is *true*.<br /><br />
 
+
 
+			You should not change this, as it used internally for optimisation.
 
+		</div>
 
+
 
+		<h3>[property:Vector3 position]</h3>
 
+		<div>
 
+			This is set equal to [page:Object3D.DefaultUp] (0, 1, 0), so that the light shines from the top down.
 
+		</div>
 
+
 
+		<h3>[property:RectAreaLightShadow shadow]</h3>
 
+		<div>
 
+			A [page:RectAreaLightShadow] used to calculate shadows for this light.<br /><br />
 
+
 
+			<em>Note:</em> this is not yet implemented for this light type! (r83)
 
+		</div>
 
+
 
+
 
+		<h3>[property:Object3D target]</h3>
 
+		<div>
 
+			The RectAreaLight points from its [page:.position position] to target.position. The default
 
+			position of the target is *(0, 0, 0)*.<br />
 
+
 
+			*Note*: For the the target's position to be changed to anything other than the default,
 
+			it must be added to the [page:Scene scene] using
 
+			<code>
 
+				scene.add( light.target );
 
+			</code>
 
+
 
+			This is so that the target's [page:Object3D.matrixWorld matrixWorld] gets automatically
 
+			updated each frame.<br /><br />
 
+
 
+			It is also possible to set the target to be another object in the scene (anything with a
 
+			[page:Object3D.position position] property), like so:
 
+			<code>
 
+var targetObject = new THREE.Object3D();
 
+scene.add(targetObject);
 
+
 
+light.target = targetObject;
 
+			</code>
 
+			The RectAreaLight will now track the target object.
 
+		</div>

+		<h2>Methods</h2>
 
+		<div>
 
+			See the base [page:Light Light] class for common methods.
 
+		</div>
 
+
 
+
 
+		<h3>[method:RectAreaLight copy]( [page:RectAreaLight source] )</h3>
 
+		<div>
 
+		Copies value of all the properties from the [page:RectAreaLight source] to this
 
+		RectAreaLight.
