ABSTRACT:
An adjustable-length light fixture having a standard fitting for connection to an incandescent light socket and providing for convenient conversion of a light fixture from incandescent use to use with another type of light source, such as fluorescent. The adjustable-length fixture includes an extensible member with two telescopically engaging portions and a positive action latch to inhibit further extension of the member once a desired length has been selected. The latch includes a resilient latch member on one telescopically engaging portion, and a number of rachet-like recesses on the other of the telescopically engaging portions, the recesses being so shaped as to inhibit further extension of the length of the fixture, but to facilitate shortening of the length as needed for installation purposes.
