If you've ever experienced a partial power outage, you know just how weird it seems. You thought you had a steady stream of power, so if it was compromised, you’d experience less power throughout the house rather than half on, half off, right? That’s not always the way it works. From the viewpoint of an engineer or a professional electrician, a partial power outage would be better described as a phase loss.

Although the bulk of your appliances run on 110 volts, your stove and laundry use 220 volts, as does your water heater ad HVAC system. That extra amount of power isn't a doubling of your electric flow, but full use of what's available. Your lights and appliances are actually running on half your available electric source in order to cut your bill by using the electricity more efficiently. The power flow coming into your home is actually two sets of 110 volts, designated as “phase 1” and “phase 2” that share a ground to safely eliminate excess power.

What that means in layman’s terms is that you have two distinct power sources. They run together in what appears as a single line, but that’s why you have a breaker box. There’s more going on in that box than just safety circuits to prevent overflow. It directs the power according to your needs.

In the breaker box, that power that is supplied is magnified exponentially. The full 220 volts is sent to those few appliances that need it. The rest of your home, the lights, outlets, television and hair dryer, well, they are actually only running on one phase, or half the available power. That’s why you think in terms of 110 volts, because your plug-in electric units only use 110 volts.

Around the world, every city offers something different. Though they all have hustle and bustle, lots of buildings, and usually traffic, when you’re on their streets you would never mistake San Francisco for Cairo, Toronto for Tokyo, or Berlin for Rio de Janeiro. But what about from space? During the day, these cities tend to blend in with their surrounding countryside. However, when lit up at night, it’s easy to see how varied these cities can be.

Is it possible to tell anything about the life and culture of our cities when viewing their lights from above? You might be surprised at how much.

Landmarks

Can you guess which cultural icon jumps out of this landscape?

Now, take a look at this photograph of Denver, a much newer city. The streets are mapped out in a much more orderly, grid-like way, aligned North-South and East-West.

The majority of urban areas in Tokyo use green mercury vapor lamps. Only the most newly built areas glow the standard orange.

Development

When examining a city’s lights from above, you can also learn about development, community growth, and infrastructure. Check out this unique photo of two cities from two countries side-by-side – the border towns Cuidad Juarez, Mexico and El Paso, Texas.

Are you still using incandescent light bulbs? Your electrician would recommend a different course. Efficient lighting technology has blown up in the last few years, and advanced technologies are just getting better. Light emitting diodes, or LEDs, are at the forefront of modern lighting thanks to their inexpensive and long-lasting luminescence. Some of these new diodes are leading the pack in must-have lighting features, including smart home integration that you can control with your phone. Read on to learn more about the latest in LED technology.

Upfront Costs are Dropping

One of the biggest complaints about early LEDs was the price. Almost any LED will save you money over time compared to an incandescent bulb, since they use 25 to 80 percent less electricity and can last up to 25 times as long, but many consumers balked at paying the $35 or higher retail price for a single bulb. Newer models, however, can recreate the look of that classic 60 watt incandescent bulb with fewer LED panels, meaning they are cheaper to produce and sell for $10 or less.

Options are Expanding

Other common complaints about the first LED models were that the warmth of the light wasn't quite right and they didn't work with accessories like dimmers. With today's technologies, however, you can find LEDs that give off almost any color and lighting profile, allowing you to mimic the look and feel of your old incandescent bulbs or tailor your room to fit more eclectic tastes. Not every LED is compatible with standard dimmers yet, but many are – just check the label on the box to make sure.

Make it a Smart Bulb

Many new LED models are designed specifically to work with smart technology. That means you can control them from your phone no matter where you are, set up a schedule for them to turn on and off, and even have different colors or light intensities at different times. Newer bulbs are also optimized to work with your other smart home systems to move you closer to a goal of integrated whole-house control.

Turnkey Functionality

One of the biggest advantages of upgrading to LEDs is how easy it is. There's no need to hire an electrician to set up new wiring or fixtures – the bulbs screw right into the pre-existing bases, out of the box. If you want tips on how to make the most of your new lighting options and create the room profile that fits your home, however, don't hesitate to call up your local electrician for guidance and advice.

Your home is supposed to be your safe place, your sanctuary, but if you have an older home, it can quickly become a nightmare. Old home wiring, especially if the wiring is 50 years or older , can put your home and everyone it it at risk for an electrical fire. While wiring doesn’t quickly age, it does age, it does break down, and it does carry risks. Keeping an eye on your home’s wiring and the way that it behaves is one of the best ways to avoid an electrical fire and protect your home. Your home is trying to tell you exactly what it needs more often than not, so keep an eye out for some of the following signs that your home’s wiring is too old and needs to be replaced by a professional electrician.

While there could be a variety of reasons you might have dimming or flickering lights in your house, if it becomes a regular occurrence, it’s time to get an electrician out to your house. These kinds of symptoms are your house telling you that there is something going on in your electrical system. Whether it’s that there is too much power being drawn at one time or that the wiring is failing, a licensed electrician can help to diagnose and fix the issue.

If you’ve had a rodent problem in your home at any time, it’s exceptionally important to have your electrical system evaluated. While rodents would prefer to munch on the cereal in your cabinet, there is something about home wiring that is exceptionally appealing to them. While they’re burrowing around in your walls, there is a high chance that they either chomp through wiring or knick it enough to expose the wiring to the insulation in your walls. Both scenarios can put your home at risk for an electrical fire at any time.

If you’ve never had a circuit breaker trip on a regular basis, then you probably don’t know how absolutely frustrating it can be, especially when the problem is probably hidden somewhere behind the walls. A circuit breaker that continues to trip is a big indication that something is wrong with your wiring. Instead of trying to force it on, make sure to call your electrician to help root out the cause of the problem in order to fix it.

If you’ve ever gone to plug in an appliance and been shocked, that’s probably not a good sign. However, if this happens regularly where you get shocked or your switches and outlets start to look discolored from burns, you have a big problem on your hands. These signs are indicative of a wiring problem and wiring shorting from the energy heavy appliances that are more common today. Don’t just hide the problem with a new outlet cover, have the problem checked out and repaired.

Lastly, don’t dismiss random burning smells or the sharp smell of burning ozone. Both could be indicators that something is going on behind your home’s walls that you can’t see. When you flip a light switch, this connects a live electrical wire and allows power to continue into a light fixture or appliance. If there is burning when the switch is flipped on, the odds are the problem is in the wiring that connects the switch and the light fixture. However, a licensed electrician can determine the extent of the damage and what the problem is.
