Over the past two years, light-emitting diode (LED) luminaires have begun competing effectively against the fluorescent troffer as performance increases and costs decrease. With nearly 1 billion fluorescent luminaires installed in the United States, according to the Department of Energy (DOE), this is a big opportunity.

ASHRAE/IES 90.1 2010, the national energy reference standard, requires building exterior lighting to be turned off and/or reduced when not in use. The goal is to save energy by ensuring exterior lighting is only used when needed; lights that are required to remain on for security after normal business hours must be dimmed. READ MORE

The organic light-emitting diode (OLED) is one of the lighting industry’s most exciting technologies. It offers extraordinary energy-saving potential, while enabling unique user experiences. However, its development is about seven years behind its popular cousin, the LED, and significant technical advances must occur before broader adoption is possible.
 The promise of OLED

ASHRAE/IES Standard 90.1 provides states and other jurisdictions a model commercial building energy code. The Department of Energy recognizes the 2010 version as the national energy reference standard, and the International Energy Conservation Code recognizes 90.1 as an alternate compliance standard.

In late 2012, the California Energy Commission (CEC) published a voluntary specification recognizing quality light-emitting diode (LED) lamps intended to replace screwbase incandescent lamps in luminaires. Called the Quality LED Lamp Specification (QLS), it covers a range of omnidirectional and directional (spot and flood) lamps.
