What Do the Terms on Energy-Saving Light Bulbs Mean?

There's a reason your parents used to scold you for not turning off a light when you left a room. According to the U.S. Department of Energy, an average American household uses up to 5 percent of their total energy expenditure on lighting. Living rooms get flooded with light. Dining rooms and dens are full of lighting accents. Motion lights, hallway lights, bathroom vanity lights, lamps—we like our lives to be nice and bright.

Fortunately, energy-saving lighting sources have largely replaced the conventional incandescent bulbs that once used up a substantial amount of power. Those bulbs heated up a coil, or filament, of tungsten wire that gave off light. Roughly 90 percent of the energy they passed on was in the form of heat, which siphoned off energy and kept utility bills inflated. Today's bulbs brighten without the waste. That's the good news. The bad? The varieties of bulbs can be confusing. If you've ever been lost in the fixtures section of the hardware store, here's a quick primer on what these terms mean.

Halogen Incandescent:

These are incandescent light bulbs that contain a halogen gas-filled capsule around the filament to help increase energy efficiency. While cheaper to operate than a conventional incandescent bulb—they use 25 to 30 percent less energy—they don't produce as much of a cost savings as other options. On the plus side, they reach full brightness immediately. Other choices may take time to warm up.

Compact Florescent Lamp (CFL):

When you see a coiled light bulb, it’s likely to be a CFL, which is simply a downsized version of the tubular florescent lighting seen in commercial spaces. Instead of an electric current traveling through a filament like in an incandescent bulb, the current goes through a tube containing argon and mercury vapor. The resulting ultraviolet light activates phosphor inside the tube, which emits light. It uses one-third of the energy of a halogen incandescent. The downside? They can take a little time to warm up, especially if used outdoors. They also contain mercury, a potential health hazard if the bulb breaks. (See the "mercury" entry below.)

Light Emitting Diode (LED):

This type of bulb uses a semiconductor to convert electricity into light. In addition to being energy-efficient, they usually last eight to 25 times longer than halogen incandescent bulbs and four to eight times longer than CFLs—perhaps as long as 18 to 46 years. You'll probably pay more up front, but the expense is offset by their durability. Most LEDs are compatible with dimming switches, too. Most CFLs aren't, so if that's important to you, you'll want to stick with LED.

Energy Star:

A bulb with an Energy Star label was evaluated by a third party to make sure its energy-saving claims are accurate, and they'll typically have a longer warranty than bulbs without the endorsement.

But what about the "nutritional label" style information box that appears on light bulb packaging? Let's take a closer look.

Federal Trade Commission

Brightness:

You have probably inferred that brightness refers to the light output given off by a bulb. This is measured in lumens and rounded off to the nearest five. (A bulb will never be 822 lumens. It's 820.) The higher the number, the brighter the bulb. Since you're probably used to shopping by wattage, consider that a bulb with 800 lumens is roughly the equivalent of a 60-watt incandescent. A 1100 lumen bulb will resemble a 75-watt bulb.

Estimated Energy Cost:

This is a rough estimate of much it will cost an average household to operate the bulb. What's average? The wattage of the bulb is calculated with three hours of daily operation at a cost of 11 cents per kilowatt. Your actual cost will go up or down whether you use it more or less or pay your energy supplier a different amount.

Life:

This is how long the bulb is expected to last based on the same usage estimated for the energy cost and rounded to the nearest tenth of a year.

Light Appearance:

This refers to the color temperature of the bulb measured in Kelvin, a temperature scale measuring light color. The range is from 2600 K (yellow and warm) to 6600 K (blue and cool). Bright white is about 3500 K. You should probably avoid anything above 3000 K for any interior room.

Energy Used:

This is how much energy the bulb will require and is measured in watts. The lower the wattage, the cheaper it costs to operate. This is where the energy savings materializes, as a 10-watt LED bulb may give off as much light as an old 60-watt incandescent.

Color Rendering Index (CRI):

It's not on all bulb packaging, but if you see it, it refers to how accurate colors will appear under the bulb's light on a scale of 0 to 100. Halogen incandescent bulbs score high. CFLs and LEDs aren't quite as accurate, though they may still get the job done. Try to get a high CRI if you'll be using the bulbs in a bathroom, as skin tone can appear off with lower CRI numbers.

Mercury:

You might see some CFL bulb packaging with a mercury disclosure. This isn't an issue if the bulb remains intact, but if it breaks, it might release potentially hazardous mercury vapor and the introduce the very small possibility of mercury poisoning. Avoid using CFL bulbs in kids' rooms if there's potential for knocking over a lamp or light. Broken bulbs that contain mercury should be cleaned up by following Environmental Protection Agency guidelines—picked up with tape, not vacuumed—and disposed of properly. Old bulbs should be recycled.

Can the Electoral College Reverse the Results of an Election?

Every four years, people talk about the oddness of the Electoral College. And just like 2000's popular vote/Electoral College mismatch, after the 2016 election, some citizens attempted to flip electors from Donald Trump to either Hillary Clinton or a third candidate (if enough electors go to the third candidate, the House would then have to choose from among the top three).

Which leads to the question: Can the Electoral College actually change the results of the election? It’s an awkwardly worded question for a very specific reason, and the answer is no. But for the question people think that they’re asking—could the Electoral College reverse the results of the election?—the answer is yes, although it’s profoundly unlikely.

The reason it’s an oddly worded question is that the November election is not a vote for president. The vote is for a set of electors who will then go and vote for the president in December. Therefore, the electors cannot change the results of the election since they’re the ones being elected. In one of the Federalist Papers, Alexander Hamilton explained the reasoning for forgoing direct democracy, as well as why they avoided letting politicians make the decision. Largely, the problem was that neither the public nor the politicians could be trusted. Hamilton wrote:

“The Executive should be independent for his continuance in office on all but the people themselves. He might otherwise be tempted to sacrifice his duty to his complaisance for those whose favor was necessary to the duration of his official consequence. This advantage will also be secured, by making his re-election to depend on a special body of representatives, deputed by the society for the single purpose of making the important choice.”

There were other issues the Founding Fathers were trying to avoid as well, such as the risk of a smorgasbord of regional candidates. As historian Jack Rakove told Stanford News in 2012, “it would become truly difficult to produce a popular majority with a field of favorite sons.”

More controversially, the Founding Fathers faced the issue of slavery. Because enslaved people couldn’t vote, a direct popular vote would weaken the power of the South. Thanks to the three-fifths compromise, however, the slave states had greater power under an electoral system than under a direct voting system, because enslaved people couldn’t vote but did count for the number of representatives. And more representatives meant more electors (the number of electors equals the state’s number of representatives plus the number of senators). As James Madison said in 1787:

“There was one difficulty however of a serious nature attending an immediate choice by the people. The right of suffrage was much more diffusive in the Northern than the Southern States; and the latter could have no influence in the election on the score of the Negroes. The substitution of electors obviated this difficulty and seemed on the whole to be liable to fewest objections.”

But objections to the elector’s powers appeared as soon as races got competitive. In 1796, Pennsylvanian Samuel Miles became the first known faithless elector when, despite being chosen as a Federalist, he voted for opposition candidate Thomas Jefferson. In a letter to the Gazette of the United States, a disgruntled Pennsylvania voter asked, “What, do I choose Samuel Miles to determine for me whether John Adams or Thomas Jefferson shall be President? No! I choose him to act, not to think.”

SO WOULD IT WORK?

As we have written about before, in about half the states plus Washington, D.C., electors are required to vote for their state’s popular vote winner—some states to the point that any attempt to defy this would forfeit the elector’s position. They’re extreme, but in the controversial 1952 Ray v. Blair case, the Supreme Court ruled that requiring pledges from electors to vote for a particular candidate was constitutional. But the question that remains unanswered is whether any punishment for breaking those pledges is constitutional. It’s never mattered, but would quickly become a critical issue if electors defected en masse.

Regarding the 2016 election, others say that because Hillary Clinton had already conceded, this strategy wouldn’t have worked. But there’s no requirement that an elector vote for a viable candidate. In 1976, one of the electors voted for Ronald Reagan, who hadn’t even won his party’s primary. In 1956, another elector voted for a local circuit court judge rather than Adlai Stevenson.

A stronger issue standing in the way is how electors are chosen. Generally, in spring and summer, each state’s political parties nominate a slate of electors from a list of party faithful. Any attempt to get defections would require electors to go against a party that chose them specifically for their loyalty.

The Ray v. Blair decision gave one of the most famous dissents in Supreme Court history, where Justice Jackson wrote, “No one faithful to our history can deny that the plan originally contemplated, what is implicit in its text, that electors would be free agents, to exercise an independent and nonpartisan judgment as to the men best qualified for the Nation's highest offices.” While it would be considered highly irregular and is highly unlikely, the possibility is there. And will remain there until January 6, 2021, when the votes are officially counted before a joint session of Congress.
