OSRAM SYLVANIA Showcases QUICKTRONIC® QTO Outdoor Metal Halide and High Pressure Sodium Dimming Systems
Industry Leading Low-Frequency Electronic Dimming Ballasts Increase Lamp Life and Deliver Improved Energy Savings


Las Vegas and Danvers, Mass. (May 9, 2012) – Known for market leadership with industry leading sustainable lighting solutions, OSRAM SYLVANIA introduces LIGHTFAIR Innovation Award-winning QUICKTRONIC® QTO Outdoor metal halide and high-pressure sodium dimming ballasts. These RoHS compliant electronic ballasts offer incredible versatility for highly efficient and controllable outdoor lighting as they are suitable for use with METALARC® POWERBALL Ceramic metal halide, METALARC quartz metal halide and LUMALUX® high pressure sodium lamp types from 100W to 200W. The QUICKTRONIC QTO outdoor electronic dimming ballasts are also the industry’s first UL Type II wet location listed, electronic dimming HID ballasts meeting the line transient protection requirements of IEEE/ANSI C62.41 Category C, which eliminates the need for additional surge protection.

When the QUICKTRONIC QTO outdoor dimming electronic ballasts are paired with the new METALARC POWERBALL Ceramic 100W ET23.5, 150W ET23.5 and 200W ET18 metal halide lamps, there are energy efficiency gains as well as the flexibility of the ballast’s dimming functionality. These lamps have an average rated life of 24,000 hours, 80 percent mean lumens, excellent color stability and high CRI in the mid 90s.  These SYLVANIA lamp and electronic ballast systems reduce energy costs by up to 25 percent when compared with standard quartz metal halide and magnetic ballast systems. Even further energy savings are possible with the ballast’s three dimming modes: 0-10V dimming, step-dimming from 100 to 50 percent power and an innovative option called Astrodim. Astrodim enables the ballast to learn the operating cycle of the luminaire system and dim over an application-defined time period without the need for additional control wires.  When QUICKTRONIC QTO outdoor dimming ballasts and SYLVANIA high intensity discharge lamps are specified together, the system is covered by the comprehensive QUICK 60+® System Warranty.
