 ====== Spectral Light ======
-provided by the plugin LightLibrary
+//provided by the plugin LightLibrary//
 This library provides predefined SPD files for light sources.
+{{ :01_user_documentation:03_interacting_with_groimp:02_panels:19_assets_libraries:spectral_light.png?direct&400 |}}
+====== Functionalities ======
+From the panel it is possible to use the following functions on a selected spectral:
+  * __add as map__: to add a SpectralLightNode to the [[01_user_documentation:03_interacting_with_groimp:02_panels:02_explorers:14_light_spectra|Spectra explorer]]
+  * __add as light source__: to add as a light source to the [[01_user_documentation:03_interacting_with_groimp:02_panels:02_explorers:17_lightsources|]]
+  * __add to scene__: to create a lightNode with a light source with the spectral as input and add it to the current scene
+  * __apply__: apply on a selected object if possible (if the object is a light Node, or a light source). If the current light source of this object is not spectral it will be used as light input on the spectral Light
+  * __Light Sources__: open the Light explorer
+====== RGG usage ======
+To use this SPD through RGG code a set of functions can be used:
+to get a SPD:
+<code java>
+spdLib("LED Red (660 nm)")
+</code>
+to get a SpectralLightMapNode object:
+<code java>
+spectralMapLib("LED Red (660 nm)")
+</code>
+to get a SpectralLight object.
+<code java>
+spectralLightLib("LED Red (660 nm)")
+</code>
+to get a SpectralLight with a PhysicalLight as a source (see Spectral library).
+<code java>
+spectralPhysicalLightLib(High-PressureSodium(HPS),"LED Red (660 nm)")
+</code>
+A simple working example could be:
+<code java>
+protected void init ()
+[
+  Axiom ==> LightNode().(setLight(spectralLightLib("LED Red (660 nm)")));
+]
+</code>
