This entity is not in the FGD by default.
It should not be put directly in a map because it doesn't work in modern VRAD.

This entity is Obsolete. Its use is discouraged, and it may only exist/function in older engine branches.

light_glspot is a point entity available in all Source games. A leftover from Half-Life 2's early development (1999-early 2001). In the leaked Half-Life 2 "beta" builds of VRAD, it acted the same as light_spot, but this functionality was removed in retail VRAD.

AltNames:light, light_spot, light_glspot, and (in all games since ) light_directional are all tied to the same C++ class in game, and only differ in VRAD.
