Light

Light causes an object to glow like a torch, shedding bright light in a 7m radius (and dim light for an additional 7m feet) from the point the caster touches. The effect is immobile, but it can be cast on a movable object. Light taken into an area of psionic darkness does not function.

A light ability (one with the light descriptor) counters and dispels a darkness ability (one with the darkness descriptor) of an equal or lower level.
