The National Electrical Manufacturers Association (NEMA) published ANSI C136.41-2013 For Roadway and Area Lighting Equipment–Dimming Control Between an External Locking Type Photocontrol and Ballast or Driver. This standard describes methods of light level control between an external locking type photocontrol (or similar device) and a dimmable ballast or driver for street and area lighting equipment. […]
NEMA Publishes NEMA BL 3-2013 Dimming Ballast Energy Performance
The National Electrical Manufacturers Association recently published NEMA BL 3-2013 Dimming Ballast Energy Performance. This standard provides a methodology for applying existing test methods for program start ballasts to fluorescent dimming ballasts. It also provides a method to calculate ballast luminous efficiency (BLE) for fluorescent dimming ballasts. Information for proper lamp and ballast compatibility for […]
Last Chance for Commercial Buildings Deduction?
The Energy Policy Act of 2005 created the Energy-Efficient Commercial Buildings Tax Deduction (CBTD) to encourage owner investment in energy-efficient building systems. The CBTD establishes a special tax deduction rewarding investment in energy-efficient interior lighting, HVAC/hot water systems and building envelope, subject to a cap of up to $1.80/sq.ft. It’s an accelerated tax deduction, meaning […]
IEC Publishes New Ultra-Low Power Consumption Wireless Technology Standard
The International Electrotechnical Commission (IEC) has ratified a new standard–ISO/IEC 14543-3-10–for wireless applications with ultra-low power consumption pioneered by EnOcean. The standard can be downloaded from www.iso.org. The new standard is geared to wireless sensors and wireless sensor networks with ultra-low power consumption. It also includes sensor networks that utilize energy harvesting technology to draw […]
