Optanium ballasts for T5 and T8 lamps are part of our effort to promote environmental responsibility through energy efficient products, lighting systems, services and expertise through Philips Advance branded products. These ballasts are part of an overall high-efficiency lighting system that can help you achieve LEED certification, meet ASHRAE standards and become compliant with California title 24 energy efficiency standards or any other local energy code applicable to you or your customers. Optanium ballasts will help you and your customers meet a variety of application challenges, including luminaire design, installation, maintenance and evolving lamp technology. Optanium ballasts are available in standard light output, low-watt and high light output designs. Also these ballasts come in options with cold-starting capability down to -20 deg F (with standard fluorescent lamps). These two features combined make them ideal for just about any T5 or T8 fixture design and application. These ballasts are available in either instant start or programmed start ignition for extended lamp life in frequent switching applications such as those where occupancy sensors or motion detectors are being used. Optanium ballasts are also available in program start with parallel wiring.
