Combining the best of both worlds, the 5005 Up & Accent Fixture comes factory installed with Vista's new MR-16 LED lamp. Boasting the energy savings of LED technology and the flexibility and performance of MR-16 Halogen lamps, Vista's new MR-16 LED lamps come in your choice of 4.5W (equivalent to 20W halogen) or 5.5W (equivalent to 35W halogen) factory-installed. Available in 15°, 25°, 36° and 60° beam spread options. This low voltage up & accent fixture is constructed of die-cast, copper-free aluminum for strength and reliability. The housing is equipped with an oversized silicone O-ring to protect against moisture and dust intrusion. At the base of the housing is a high temperature silicone diaphragm gasket which incorporates an innovative air valve that prevents a vacuum from forming within the fixture during dramatic temperature changes. A clear, tempered, shock and heat-resistant, soda-lime glass lens safeguards the lamp and optics. A super durable polyester powder coat finish is available in 18 colors. The intelligently engineered fully adjustable knuckle is made from injection-molded, fiber-reinforced composite which effectively isolates the fixture from the harmful corrosive soil. The 5005 is shipped with a standard 4.5W, 36° flood MR-16 LED lamp, unless otherwise specified. Mounting hardware is included – choice of ABS ground stake, mounting canopy, or tree-mount canopy.
