Note: This documentation is for the old 0.5.0 version of A-Frame. Check out the documentation for the current 1.6.0 version

The light component defines the entity as a source of light. Light affects all materials that have not specified a flat shading model with shader: flat. Note that lights are computationally expensive we should limit number of lights in a scene.

<a-entity light="color: #AFA; intensity: 1.5" position="-1 1 0"></a-entity>

By default, A-Frame scenes inject default lighting, an ambient light and a directional light. These default lights are visible in the DOM with the data-aframe-default-light attribute. Whenever we add any lights, A-Frame removes the default lights from the scene.

<!-- Default lighting injected by A-Frame. -->
<a-entity light="type: ambient; color: #BBB"></a-entity>
<a-entity light="type: directional; color: #FFF; intensity: 0.6" position="-0.5 1 1"></a-entity>


We will go through the different types of lights and their respective properties one by one.

Property Description Default Value
type One of ambient, directional, hemisphere, point, spot. directional
color Light color. #fff
intensity Light strength. 1.0


Ambient lights globally affect all entities in the scene. The color and intensity properties define ambient lights. Additionally, position, rotation, and scale have no effect on ambient lights.

We recommend to have some form of ambient light such that shadowed areas are not fully black and to mimic indirect lighting.

<a-entity light="type: ambient; color: #CCC"></a-entity>


Directional lights are like a light source that is infinitely far away, but shining from a specific direction, like the sun. Thus, absolute position do not have an effect on the intensity of the light on an entity. We can specify the direction using the position component.

The example below creates a light source shining from the upper-left at a 45-degree angle. Note that because only the vector matters, position="-100 100 0" and position="-1 1 0" are the same.

<a-entity light="type: directional; color: #EEE; intensity: 0.5" position="-1 1 0"></a-entity>

We can specify the direction of the directional light with its orientation by creating a child entity it targets. For example, pointing down its -Z axis:

<a-light type="directional" position="0 0 0" rotation="-90 0 0" target="#directionaltarget">
<a-entity id="directionaltarget" position="0 0 -1"></a-entity>


Hemisphere lights are like an ambient light, but with two different colors, one from above (color) and one from below (groundColor). This can be useful for scenes with two distinct lighting colors (e.g., a grassy field under a gray sky).

<a-entity light="type: hemisphere; color: #33C; groundColor: #3C3; intensity: 2"></a-entity>
Property Description Default Value
groundColor Light color from below. #fff


Point lights, unlike directional lights, are omni-directional and affect materials depending on their position and distance. Point likes are like light bulb. The closer the light bulb gets to an object, the greater the object is lit.

<a-entity light="type: point; intensity: 0.75; distance: 50; decay: 2"
position="0 10 10"></a-entity>
Property Description Default Value
decay Amount the light dims along the distance of the light. 1.0
distance Distance where intensity becomes 0. If distance is 0, then the point light does not decay with distance. 0.0


Spot lights are like point lights in the sense that they affect materials depending on its position and distance, but spot lights are not omni-directional. They mainly cast light in one direction, like the Bat-Signal.

<a-entity light="type: spot; angle: 45"></a-entity>
Property Description Default Value
angle Maximum extent of spot light from its direction (in degrees). 60
decay Amount the light dims along the distance of the light. 1.0
distance Distance where intensity becomes 0. If distance is 0, then the point light does not decay with distance. 0.0
penumbra Percent of the spotlight cone that is attenuated due to penumbra. 0.0
target element the spot should point to. set to null to transform spotlight by orientation, pointing to it’s -Z axis. null
