New article by Campus Facility Maintenance Magazine on Lamp Recycling

Bulb Eater As most university maintenance personnel and electricians already know, nearly all lamps are considered hazardous waste and spent bulbs can no longer be tossed into dumpsters. Due to the mercury content in fluorescent, mercury vapor and other lamps and lamp fragments, the United States Environmental Protection Agency (EPA) recommends recycling of lamps and lamp components as the proper method of disposal.

Besides federal regulations, institutions must also follow all applicable state and local regulations. For example, some states prohibit even the newer non-hazardous low-mercury lamps from being disposed of in solid waste landfills. To eliminate the liability and risk of fines due to improper disposal, universities must recycle their lamps.

Should I Turn Off Fluorescent Lighting When Leaving A Room?


Short Answer: Turn them off if you will be gone for more than about 15-20 minutes (for details keep reading).

There are a few misconceptions about fluorescent lighting that keep too many people from turning lights off to save energy. The first misconception is that it takes more energy to start a fluorescent light than it takes to run it. The second misconception is that turning a fluorescent light off and on will wear it out right away. Like many of our myths about energy, there is a small amount of truth in the belief. (Special thanks to Steve Selkowitz of Lawrence Berkeley National Labs for doing the research that this article is based on.)

Are Super T-8s Really Super?


A group of energy-efficient fluorescents have been dubbed "super T-8s." The name implies something special. The Lighting Research Center recently covered whether they're really so super in a "LIVE! From the LRC" teleseminar.

Peter Morante, director of Energy Programs at the LRC, explained that Super T-8s have an alias: "High Performance T-8s."

"There are no standards to describe what a 'super' T-8 is, and each manufacturer describes the product differently," he said.

From LRC studies, the high performance T-8s have a:

  • Mean system efficacy (mean lumens/watt) of greater than, or equal to 90, compared to 85-92 for a standard T-8;
  • Color rendering index of greater than or equal to 81, compared to 75-82 for a standard T-8;
  • Minimum initial lamp lumens greater than or equal to 3100, compared to 2800-2900 for a standard T-8;
  • Lamp life (in hours) greater than or equal to 24,000, compared to 20,000 for a standard T-8;
  • Lumen maintenance of greater than or equal to 94 percent, compared to 90-92 percent for a standard T-8.

In answer to the question, "where do I use Super T-8s," Morante recommended the following:
