{{this is a|point entity|name=light_spot}} It is a cone-shaped, invisible light source. Can be turned on and off through inputs, though switchable lights may cause lightmap errors. This is a static spotlight that can be pointed at another entity. 
{{note|When using this entity it is often necessary to turn the brightness value up significantly for the effects of the light to be visible compared to other lighting entities. Values of 3000-4000 are sometimes necessary for light sources like streetlights.}}
{{altnames|{{mono|[[light]]}}, {{mono|light_spot}}, {{mono|[[light_glspot]]}}, and {{l4d|since}} {{mono|[[light_directional]]}} are all tied to the same C++ class in game, and only differ in VRAD.}}
==Keyvalues==
{{KV Targetname}}
:{{Light NameWarning}}
{{KV|Entity to point at|intn=target|target_destination|The name of an entity in the map that the spotlight will point at. This will override the spotlight's angles.}}
{{KV|Inner (bright) angle|intn=_inner_cone|integer|The angles of the inner spotlight beam.}}{{note|Values larger than 90 are clamped to 90; this can be circumvented with custom RAD compiler, but lighting on dynamically-lit models may behave unexpectedly.}}
{{KV|Outer (fading) angle|intn=_cone|integer|The angles of the outer spotlight beam.}}{{note|Values larger than 90 are clamped to 90; this can be circumvented with custom RAD compiler, but lighting on dynamically-lit models may behave unexpectedly.}}
{{KV|Focus|intn=_exponent|integer|Changes the distance between the umbra and penumbra cone. (higher values make the edge of the light more blurred.{{tip|When increasing the Focus value to for example 5 you can use the spotlight as a directional fill light.}}}}
{{KV|Maximum distance|intn=_distance|integer|This is the distance that light is allowed to cast, in inches. Non-functional in {{game link|Source 2013}} and later, use 50 and 0 percent falloff instead.}}
{{KV Angles}}
{{KV|Pitch|intn=pitch|integer|Used instead of {{code|angles}} value for reasons unknown.
:{{bug|Pitch has unexpected behavior if the <code>light_spot</code> is inside of a rotated [[instance]]. This is solved by collapsing the instance, or by using the "Entity to point at" keyvalue.}}}}
{{KV Light}}

==Flags==
{{Fl|1|Initially dark|Spawns with the light turned off, so a light switch or similar can turn it on.}}
