As of Jan.1,2011, manufacturers that want the Energy Star label must get certification from an independent lab. As a result, there are rumors afoot that manufacturers may start dropping out of the U.S. EPA's Energy Star program. These issues and more are the topic of the upcoming Illumination Summit commencing on Feb. 17 in Orlando, Fla. Keynoter Alex Baker, the EPA’s Lighting Program Manager for Energy Star will discuss Energy Star certification and the EPA’s position. Also on the agenda is Energy Star testing organization CSA, whose CEO Ash Sahi will talk about the certification process.

My friend Terry and I had each finished off a bottle of beer. I looked around for a recycling bin while Terry just pitched his bottle in the trash. Was Terry indifferent to the environment? Nah. He works at one of the biggest breweries in the U.S. and knows first-hand what happens to recycled glass. “We can't use recycled glass for making bottles. It's just too brittle. So glass put in recycling bins generally ends up in landfills anyway,” he explains. READ MORE Read More
One aspect of energy efficient lighting that is rarely discussed is the way in which it will affect the utility power system. With this in mind, we decided to measure the new modern light bulbs. We tested incandescent light bulbs (ICBs), compact fluorescent light bulbs (CFLs), and light emitting diode bulbs (LEDs). This is not an exhaustive test in that it covers only a few representative samples available from large retail chains. Nevertheless, we feel the results are a good snapshot of how present-day lighting products behave. READ MORE Read MoreFear and loathing in smart meter land
You can say one thing for smart meters: The concept of a utility or some other entity having an influence on homeowner electrical demand seems to have driven certain members of the blogosphere off the deep end. The Web is rife with conspiracy theories about sinister ulterior motives for putting such devices in the home. A lot of them have the tone of this one: “They will be able to shut your power OFF anytime they want. There will be rolling blackouts in your future caused only by your supplier wanting to conserve energy or re-route it to large corporations, and nothing else." READ MORE Read More
The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can't be dimmed. For example, even with electronic ballasts, HID (high-intensity discharge) lamps cannot be dimmed to much more than half of their maximum light output. In contrast, it is much more straightforward to dim LEDs. LEDs' p-n junction has a fairly constant forward voltage drop constituting a stable load that can be driven by a constant dc current source.
