An in-ground, pneumatically-operated, extensible-and-retractable landscape light comprised of an elongated outer housing having an air inlet in its body and an opening in its upper end into which is received in a telescoping, mating relationship an elongated inner housing which has a light source operably connected to the upper end thereof. The light source may be comprised of a light bulb and a source of electrical power, and the light source may be sheltered by an interchangeable light source sheltering unit. In use, the injection of air into the outer housing through the air inlet raises the inner housing from its retracted position to its extended position. The inner housing may be selectively locked in its extended position by a locking mechanism such as a solenoid with a solenoid plunger attached to one housing and a notch for receiving the plunger in the other housing.
