Dimmers are relatively old devices. Granville Woods patented a “Safety Dimmer” in 1896 in order to substantially reduce energy usage. Saving energy is actually the first reason on our list of reasons why you should install dimmer switches throughout your home.

The biggest advantage to dimmer switches is that they can reduce energy consumption and costs by allowing you greater control over your lighting. Traditional light switches only have two options—on (100% power) and off (0% power). However, if you want to save electricity, you have an entire spectrum of settings in between to choose from. For example, if your family is watching a movie in the living room, you don’t need the lights all the way up to see where the popcorn bowl is. Instead of leaving the living room light on during the entire movie, you can turn it down to maybe 40%.

One of the benefits of controlling the amount of power your lightbulb gets is also controlling the ambiance. In the above example, the family watching the movie managed the level of lighting in the room, allowing the living room to turn into a makeshift theater. Likewise, if a couple wanted to have a romantic dinner, they could lower the lighting in the dining room to 30% instead of relying on the dim illumination of a couple of candles.

Just a few years ago, an energy efficient LED bulb might have cost you $20 or more. But today, you may be able to get as many as six bulbs for that price, and consumers are taking notice.

LEDs were always extremely energy efficient and long lasting -- the high upfront cost was the last thing holding them back from being the obvious choice for most household lamps and fixtures. But while we waited for those prices to drop, many consumers turned to CFL bulbs -- the curly ones -- as a more affordable way to reduce their energy consumption.

Now that LEDs are so accessible, some homeowners are upgrading and wondering what to do with their collection of CFLs, some of which may have thousands of hours of light left in them.

Managing the Mercury

The primary reason why CFLs need to be handled and disposed of carefully is because each bulb contains a small amount of mercury. The mercury content is so low that you don’t need to worry excessively about health risks in the event of a broken bulb, but if thousands of CFLs pile up together in the same landfill, the combined mercury content could prove hazardous. Even in trace amounts per bulb, the risk of soil and water contamination is real.

To avoid this problem, every CFL bulb should be disposed of at a recycling facility, whether it’s broken, whole, burned out or still good.

Recycle Right

Not every recycling facility accepts CFLs. If you have curbside recycling, check the service provider’s website for information specific to CFLs. It may be that they’re able to collect and recycle these bulbs, but only if they’re packaged separately for disposal. Some facilities may require you to deliver CFLs yourself.

In addition to municipal recycling centers, CFL recycling is offered by many business, including hardware and electronics stores. If you’re looking for your nearest CFL recycling location, use Earth911’s recycling search tool.

Accidents Happen

CFLs are made of breakable glass -- a fragile barrier containing the mercury vapor within. Because of the low mercury content, you don’t need to call out the hazmat team if you accidentally break a bulb. But as a precaution, you should still treat cleanup more seriously than you would with an ordinary incandescent bulb.

If a CFL bulb breaks, immediately clear the area of people and pets. If possible, open a window or door to ventilate the room. Turn off the HVAC system so that the mercury isn’t circulated throughout the home.

When it’s time to clean up the mess, leave the vacuum behind. Like your HVAC system, it can blow the mercury vapor around your home. Instead, sweep up all the glass and bulb components into a dustpan and deposit them into a plastic bag.

Use a damp paper towel to wipe down the area, and if necessary, use sticky tape to collect small glass shards. Place all cleaning materials into the bag and seal it up. Afterward, take the bag to your nearest CFL recycling location for safe disposal.

And if you need help with more substantial lighting issues, don’t take the risk of playing with electricity alone -- call up your local, licensed electricians.

Well, they told us yesterday’s Super Bowl would be the greenest one to date, but they failed to mention that as part of the plan to save energy they were going to turn the lights out in the second half.

Just kidding. This year’s Super Bowl might go down in the books for its lighting “abnormality,” but certainly there were some “bright spots” about this year’s lighting as well. Today, I’m going to reflect on  both.

What actually caused this thing?

After the lights came back on and the game ended, Entergy New Orleans, the stadium’s energy provider, and Superdome operator SMG issued this statement in an attempt to “shed some light” on the situation:

“A piece of equipment that is designed to monitor electrical load sensed an abnormality in the system. Once the issue was detected, the sensing equipment operated as designed and opened a breaker, causing power to be partially cut to the Superdome in order to isolate the issue. Entergy and SMG will continue to investigate the root cause of the abnormality.”
