Warning:While this entity does exist in 
Black Mesa, it is very different from other games. Instead of using lightmaps it uses 
Deferred lighting. However, unlike Black Mesa's new lighting entities, it does not support specular reflections and dynamic shadows. This entity is used for some effects and entities, such as prop_flare or npc_alien_controller. Many inputs are missing, except TurnOff, TurnOn, Toggle and base entity inputs. Console commands for this entity don't work. To use all these missing features, see newLight_Point
Warning:If enable - light source will not work in Black Mesa.

Template:Entity It is an invisible light source that changes over time. Can be turned on and off through inputs, and can aim at any object, including moving ones. Dynamic lights are calculated on the fly in the game, which means they have a higher processing cost but are much more flexible than static lighting. It is also the only entity except env_projectedtexture that can light up brushes in real-time (but it doesn't replace their original lighting).

An example in Black Mesa
Black MesaKeyvalues
- Entity to point at (target) <targetname>
- The name of an entity in the map that the dynamic light will point at.
- Light color (_light) <color255>
- The RGB render color of the spotlight. Colors must be between 0 and 255.
- Light brightness (brightness) <integer>
- The intensity of the spotlight.
- Inner (bright) angle (_inner_cone) <integer>
- The angles of the inner spotlight beam. 0 makes it omnidirectional.
- Outer (fading) angle (_cone) <integer>
- The angles of the outer spotlight beam. 0 makes it omnidirectional.
- Pitch (pitch) <integer>
- Used instead of Pitch Yaw Roll's value for reasons unknown.
- Maximum distance (distance) <float>
- This is the distance that light is allowed to cast, in inches.
- Spotlight end radius (spotlight_radius) <float>
- This is the radius of the light, in inches, at the object that it is hitting.
- Appearance (style) <choices>
- Various Custom Appearance (see below) presets.
Flags
- Do not light world (better perf) : [1]
- Do not light models : [2]
- Add Displacement Alpha : [4]
Warning:If enable - light source will not work in Black Mesa.- Subtract Displacement Alpha : [8]
Inputs
- Color <color255>
- Set the light's render color (R G B).
- brightness <integer>
- Set the light brightness.
- distance <float>
- Set the maximum light distance.
- _inner_cone <integer>
- Set the inner (bright) angle.
- _cone <integer>
- Set the outer (fading) angle.
- spotlight_radius <float>
- Set the radius of the spotlight at the end point.
- style <integer>
- Change the lightstyle (see Appearance field for possible values).
- TurnOn
- Turn the light off.
- TurnOff
- Turn the light on.
- Toggle
- Toggle the light on/off.
Outputs
Console commands
- r_dynamic <boolean>

- r_maxdlights <integer>
- Sets the maximum amount of dynamic lights.
- r_portal_use_dlights <integer> (only in
) - Enables dynamic lights behind portals
