Abstract
A bollard style light fixture, which allows the user to vary the fixture's light distribution pattern, while also eliminating the fixture's emission of glare. The fixture of this invention is also designed to absorb a minor amount of shock without damage, and provides a mechanism whereby the fixture may be quickly and easily leveled and releveled even after installation. The fixture of this invention comprises a base; a compressible base pad upon which the base rests; a support sleeve vertically extending from the base; a light source located within the support sleeve; a light-emitting window located on the support sleeve opposite the base; and an adjustable cap assembly located atop the light-emitting window vertically adjustable for variably covering the light-emitting window, thus varying the light distribution pattern of the fixture and redirecting the light rays towards the ground, eliminating glare.
