Building owners interested in entertaining a lighting upgrade proposal often are interested in an energy-saving retrofit, but they may actually need a redesign that saves energy and improves lighting quality. READ MORE

Metal halide lamps occasionally fail "non-passively" at end of life, which may cause hot quartz elements to be ejected from the light fixture, presenting a fire risk. READ MORE

Energy codes provide a minimum standard for new construction of commercial buildings. Your local code may be a unique one developed by the state or municipality, such as California’s Title 24, or may be based on a version of ASHRAE 90.1 (1999, 2001, 2004, 2007) or the International Energy Conservation Code (IECC) (2001, 2003, 2006) standards.

There currently is a push to replace linear fluorescent T8 and T12 lamps with linear light-emitting diode (LED) replacement lamps, but are LEDs ready to take on this workhorse in general lighting? The evidence suggests no, not yet anyway, except perhaps in some specialty applications, such as refrigerated display cases. READ MORE

Here’s a light source with the potential to reduce the nation’s energy costs by 6–7 percent, to reimagine the light fixture as a highly compact and dynamic element, to keep 2 to 4 tons of mercury out of landfills and incinerators each year, and to give building owners lighting that doesn’t require lamp replacement for up to a decade or longer.
