Pneumatic landscape light

An in-ground, pneumatically-operated, extensible and retractable landscape light comprising:

• a) an elongated outer housing adapted to be at least partially buried in a surrounding volume of ground, the outer housing having an upper end with an opening therein, a lower end, an inner surface. and an outer surface;
• b) an elongated inner housing having an upper end and a lower end, the inner housing being received into the opening in the upper end of the outer housing in a telescoping, mating relationship and being at least partially within the outer housing when in a retracted position and projecting at least partially outside the outer housing when in an extended position;
• c) an inlet in the outer housing for allowing air to be injected into the outer housing for pneumatically forcing the inner housing to an extended position;
• d) a light source operably connected to the elongated inner housing for illuminating an area of landscape surrounding the light;
• and
• e) a means secured to the light for selectively locking the inner housing in the extended position of the inner housing whereby the inner housing may be held in an extended position without a constant influx of pressurized air when the locking means is activated, and the inner housing may be allowed to retract when the locking means is deactivated.
