Security lighting is a great way to protect your home from intruders at night—but only when it’s working properly! Malfunctioning security lights may stay on longer than they’re supposed to, not turn on when they should turn on, or face a number of other problems that prevent them from working effectively. The following is a guide to troubleshooting security lights for some of the most common issues people face. Here’s what to do if you have the same problems!

Motion sensor lights are designed to come on when they detect movement and shut off after a few minutes when everything stops. But sometimes, motion stops and the lights stay on—usually as a result of a spike in current.

The first step in troubleshooting security lights with motion sensors that won’t shut off is to check if the time interval has been changed. Most motion sensors allow you to set a length of time for the light to stay on, usually anywhere between 30 seconds to 10 minutes. If the interval has been changed and the lights are staying on for too long, change it back to the time you want.

If that doesn’t work, go outside during the day and see if there’s anything in range of the motion detector that might be constantly moving, like a flag or even an animal nest (you might even look outside at night and see if you can see anything). If you don’t see anything, try shutting the lights off at the breaker, then restarting them.

Lights that won’t shut off are bad enough, but what about lights that won’t turn on? One common reason this happens is that artificial light is coming in from another source and is mimicking daylight, preventing the sensor from activating properly. Try to find where the light is coming from, and cover or change the direction of the sensor to avoid the light.

The underlying issue behind constantly flickering lights may vary depending on a number of factors, including whether the problem is only occurring with a single bulb or more than one at a time. If it’s only a single bulb, carefully check it to see if it’s secure in its fitting. If it is, try replacing it with a new bulb. If that doesn’t work, call an electrician for a security light repair.

This one isn’t as common as the others on our list, but in the past we’ve had customers whose security lights have been faulty when the weather was damp, rainy, or snowy. This is usually the result of low quality motion sensors, which can be temperamental in very hot or very cold weather. The certified, DC-area electricians at Kolb Electric recommend spending a little more upfront to get a quality product that you’ll be able to rely on for years with little need for security light repair.

ballast-compatible LED T8 tube for office lighting, school lighting, hospital lighting, basement lighting, and more. The energy-efficient F32T8 tube light can be used in direct-wire fixtures or to replace T8 tubes in fluorescent fixtures without removing ballasts. Designed to last 50,000 hours—5 times longer than fluorescent tubes—the LED T8 tube reduces costly repairs, disposal fees, and the need for replacements. This energy-efficient LED light uses just 18 watts of power and is comparable to a 32-watt fluorescent tube light.

Temperatures are falling rapidly, and some regions of the country have already seen snow. With winter settling in, renters and homeowners are cranking up their thermostats to stay warm and cozy while bracing themselves for a big bump in utility bills due to heating costs. Savvy consumers looking for a way to save money without sacrificing comfort might ask: Can I cut down on my winter heating budget if I lower the thermostat and make up the difference with an electric space heater?

Fuel Matters

Savings are possible, though, no matter what kind of central heat you have. According to Grist magazine, if you are using a space heater for less than one half to one third of your living space, and you lower the temperature on your thermostat for the rest of it, you can save money even if your main heater is an efficient gas model. So if your family spends most of its winter indoor time in just a few rooms of the house, go ahead and experiment with a portable heater and see if you can reduce your bills.

For even more savings, don't forget to take other steps to winterize your home, like sealing any drafty areas and hanging heavy curtains. Wear a sweater, too, so you can minimize the amount of time you need the extra boost in warmth from your heater.

Finally, avoid kerosene heaters if at all possible. They pose a greater fire hazard than electric models and can affect your indoor air quality. If they are your only option, take extra care to comply with the safety instructions. Only refuel outside and be sure the indoor space where it is used is properly ventilated. Some kerosene heaters are even illegal in certain areas, so be sure to check your local laws before you buy.

The federal Energy Star program does not rate portable heaters, but the Energy Department does provide more information about specific types of space heaters.

If you’ve ever watched the show “Holmes on Homes” on HGTV, you’ve likely seen the problems associated with old or faulty wiring.  Mike Holmes tends to get very agitated by safety issues, and for good reason.  Each year, over 40,000 homes suffer fire damage due to home electrical problems.  These electrical fires account for hundreds of deaths and thousands of injuries.  And what’s the main culprit?  Old wiring!

If you live in a classic home built before 1940, chances are you have old wiring in the house.  You may have knob-and-tube or Romex wiring, both of which can become brittle over time.  The insulation dries out and starts to crumble, causing the inner wire to become exposed. The cloth insulation around the wire deteriorates with age and eventually becomes unsafe.

But perhaps one of the biggest threats of Romex and knob-and-tube wiring is that these types of wires aren’t grounded.  That means if one of your appliances shorts out, you could become the path to the ground for the electricity.

Even if your home is only 20 or 30 years old, you could still experience electrical problems at home due to a lack of capacity.  Most homes built more than 10 years ago are not designed to handle the amount of electronics we use today.  Think about it:  if your house was built in 1980, it was built before home PCs and laptops and HDTVs and surround sound and all of the other toys and gadgets we use today.  These appliances can draw a lot of power, and your current electrical wiring may not be up to the task.

If you own one of the one million houses in the DFW area that’s more than 20 years old, it’s a good idea to have a licensed electrician come out and take a look at the wiring.  He or she can make sure that your house will be safe and productive for many years.
