The licensed electricians at Expert Electric receive a lot of questions about how motion sensing lights work and where to install them. Since our team has plenty of experience installing motion sensing lights in residential homes and commercial buildings, we figured it would be beneficial to help answer some of the more popular questions we receive. Keep reading to learn more about how motion sensing lights work, where to install them and how to install them.

Many of us are familiar with motion sensing lights as they have been around for some time now. They frequently make appearances in spy films and may even have been installed at your workplace. Nowadays, motion sensing lights are becoming an increasingly popular security measure in both commercial business buildings and residential homes. These motion sensing lights work by detecting infrared heat waves that can be found on moving objects. In order to ensure that the sensors are not triggered by non-human objects, it is necessary to dial them to a specific sensitivity setting that usually falls between 8 to 12 micrometers. To ensure that sensing lights are installed and working properly, it is best to contact a licensed electrician.

For residential homes, it is important to install motion sensing lights in different areas around the outside of the home, in both the front and back yard. For the front yard, consider installing the motion sensing lights to cover walkways, driveways, entranceways and stairs. For the backyard, it is important to cover any similar areas as well as patios, hot tubs, swimming pools and gates. Don’t feel that you should limit yourself to these areas. The placement of motion sensing lights is based upon each individual home. A good rule of thumb is to cover the most common pathways to home entrances as well as dark and hazardous areas throughout the property. The same goes for commercial properties although these properties will likely require a larger scale of motion sensing lights due to their size and valuables on hand. For questions about where to install motion sensing lights on either residential properties or commercial properties, contact the expert electricians at Expert Electric.

For commercial buildings and businesses, it is recommended that a licensed electrician takes care of the installation of motion sensing lights. This will ensure that the lights are working properly to protect the building and its valuables. Nowadays installing motion sensing lights in residential homes can be a simple process; however, dialing in the sensitivity settings so that the lights are not being prompted by non-human movement every hour of the night can be tricky. A licensed electrician at Expert Electric can have your residential motion sensing lights up and running in no time, allowing you to sleep safely and peacefully, free of frustrating false alarms.

One of the best ways to save on your energy bills is to limit the amount of energy you use in the bathroom. Easily save money and energy in your bathroom by following these 9 simple steps.

Water heating is the second largest household energy expense, after heating and cooling. Cutting your shower time by two minutes can reduce your water use and lower your energy bills.

Lowering your water heater’s thermostat to 120 °F can help you to improve the performance of your water heater and cut your water heating costs. If you plan to be away from home for at least three days, turn off your water heater or turn the thermostat down to the lowest setting.

Lighting accounts for about 10 percent of your household electricity costs. Turning the lights off when you leave the bathroom is an important energy conservation measure.

Switching to energy-saving light bulbs is one of the easiest ways to start saving energy in your bathroom. When shopping for light bulbs, look for the Energy Star label to identify energy-saving products. For further energy savings, choose LED light bulbs, which typically use 75 percent less energy than incandescent light bulbs.

Leaving your bathroom extractor fan on too long can remove heat from your home. Save energy by turning off your fan when you leave the bathroom.

Ventilating your bathroom can go a long way toward creating an energy-efficient environment; research reveals that it costs less to cool or heat a dry environment than a damp one. Improve the ventilation in your bathroom by leaving a window open when you’re taking a bath or shower.

Sealing any air leaks with caulk, weatherstrips, or sealant can cut your energy costs and create a healthier indoor environment. For best results, focus on filling gaps around your windows and plumbing.

Older water heaters can use more energy than new ones, so replacing them can help you cut your energy bills. When shopping for a new water heater, consider the size, fuel type, and energy efficiency before making a purchase.

Leaving appliances plugged in wastes energy, even when they’re not being used. Be sure to unplug your appliances after using them, or switch them off at the wall.

Learning how to conserve energy in the bathroom doesn’t have to be a challenge. By following the above tips, you can maximize your energy savings and cut your energy bills.

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.

Rolling blackouts occur when delivery of electricity from a large power source is intermittently stopped in varying places across a wide area. Rolling blackouts usually occur in tandem with natural disasters or energy crises.

Rolling blackouts prevent large power sources from blacking out completely. They have been implemented in places with a high demand for electricity, such as Japan, the U.S., Pakistan, and Ukraine.

By limiting the amount of power that can be used at one time to only certain areas, power station operators can control the power output from their generators. Should a part of the generator be at risk for failure, operators can begin a rolling blackout to limit the amount of work the generators must do. From there, they can pinpoint the problem areas and find a useful fix without taking away power from an entire area.

Rolling blackouts can prevent power outages from:

In the case of power output problems like station faults, short circuits, and electrical overloads, a rolling blackout can mitigate the risk of explosion and prevent the acceleration of large scale disasters.

Since power can only be distributed over a limited area, 100% of the electricity supply to some places will be temporarily cut off. Household items such as lights, outlets, and appliances will cease operation for a predetermined amount of time. You can gather information about rolling blackouts from the radio or news before they occur.

You should have an emergency kit in your home or business that has the necessary supplies for survival without electricity. Items to include in an emergency kit are:

Be sure to lock all of your doors and windows if possible. In developed countries, law enforcement will bolster its forces to protect areas affected by a rolling blackout. You should still remain safe and prepared whenever possible.

Should a rolling blackout elevate to a blackout, don’t be afraid to use your supplies. Even if electrical generators are running at low capacity, they still have the potential to cause larger problems should they become overloaded. A rolling blackout can quickly become a city-wide blackout.

Rolling blackouts are relatively rare. Conditions must be extreme for a rolling blackout to take effect. While the climate in the U.S. varies widely across the country, devastating natural disasters don’t compromise the electric grid more than once every 20 years.

How do tripped circuit breakers happen in the first place? An overloaded circuit is the most common reason for a breaker tripping and usually happens when a circuit has more electrical load connected to it than it really should have. Let’s say you have a 15 Amp circuit breaker that is protecting a 15 Amp circuit. If 20 Amps of current start flowing through it because a toaster, TV, radio and space heater were all connected to the same circuit and were on at the same time, then what you’re left with are tripped circuit breakers aimed to prevent overheating of the circuit.

Allow Kolb Electric, one of the premier electricians in Alexandria, Arlington, Fairfax and all of Northern VA, to guide you through the process of resetting tripped circuit breakers, which is actually quite easy.

If your breaker continues to trip immediately after you’ve reset it, this is indicative of a direct short. Do not try to reset your breakers at this point. If these steps don’t help you resolve your tripped circuit breaker problem, it’s time for you to contact a quality electrician in Virginia who can uncover the source of the problem, which could be due to one of the following:
