Sylvania Metalarc® M250/U/ED28/64032 Standard Metal Halide Lamp, 250 W Wattage, E39 Mogul Lamp Base, Quartz Metal Halide Lamp, ED28 Shape, 20000 Lumens

SYLVANIA Metalarc PRO-TECH® and Metalarc PULSE START low wattage E17 and PAR38 lamp's premium performance provides opportunities for higher maintained illumination levels and substantial energy savings. The Metalarc Pro-Tech lamp design enhances safety in open or enclosed fixtures and includes a shroud around the arc tube and, in some cases, a thicker walled outer jacket. In addition, Metalarc Pro-Tech lamps have a reduction in UV output compared to standard metal halide lamps. The use of open fixtures means more light output over life and lower maintenance costs because there are no lenses to gather dirt and dust, thus extending lamp replacement procedures. The Metalarc enclosed rated E17 lamps provide a solution for enclosed rated fixtures and contain all the benefits of the pulse start technology including reduction in color shift over the life of the lamp, better lumen maintenance and potentially longer life.
