The holidays are nearly here, which means it's time to string up the lights. And while it doesn't take an electrician to get that job done, it doesn't hurt to think like an electrician - especially when it comes to safety.

Whenever you're using electricity, heat-producing lighting and power cords, it's a good idea to observe some basic precautions to avoid accidental shock, burns, fire and tripping hazards. This and every holiday decorating season, observe these simple tips for a safe and festive experience:

Inspect and Test

Before putting up any electrical holiday decorations, take time to thoroughly inspect them for damage. If you find frayed wires or signs of melted plastic, don't use those decorations - throw them away and replace them. If they appear to be in good condition, test them before hanging them up. There's nothing more frustrating than stringing up a strand of lights only to find out it's a dud!

Upgrade Your Lights

If your lights are showing signs of wear or you just feel it's time for an upgrade, consider switching to LEDs if you haven't already. LEDs are not only brighter and more energy efficient, they're safer because they produce almost no heat.

No Dry Trees

If you have a live tree, be sure to give it plenty of water. A dry tree can burn quickly, and any significant source of heat could pose a serious fire risk. Be especially careful to hydrate your tree if you're using lights, and never allow candles in the area of your tree stand.

Careful With the Cords

Be deliberate about where you run all cords and wires, including strands of lights. Never run cords across walking paths, as this can create an unsafe tripping hazard. You should also never run cords under rugs or through doorways, as this can cause damage that could lead to electrical shock or fire.

Stay on Your Feet

If you need a ladder to hang your lights, have a friend hold the ladder and act as a spotter. Wear non-slip shoes and make sure your ladder is locked into position on a level surface before climbing.

Right Lights for the Job

Most strands of lights are rated for either indoor or outdoor use. Indoor lights are not designed to withstand all-weather conditions, and in the worst-case scenario, using them outdoors can lead to electrical shock or a fire.

Any homeowner can observe these smart tips, but they might not address all of your holiday decorating challenges. If you find that you need new outlets installed to make your lighting scheme a reality, reach out to your licensed, local electricians while there's still time to decorate!

Understanding common household light bulb shapes, sizes, and styles is important whether you’re converting outdated incandescent fixtures into energy-efficient ones or using LED bulbs for new-construction applications. Every light bulb has identifying characteristics that are represented by a letter or series of letters and a number; these are known as light bulb codes. The letter or letters in a bulb code indicate either shape or special features such as reflector type. Numbers in a bulb code indicate size in millimeters or eighths of an inch. These codes will tell you if a bulb will fit in your fixture and if it’s the right shape.

For every light fixture or application, there’s going to be a specific bulb or light bulb shape that will fit best and provide the right type of light. If you understand bulb codes, it’s easy to look at a light fixture and know right away what kind of bulb you’ll need.

Let’s talk about light bulb groups, their bulb codes, and what applications those bulbs are typically used for.

Standard/arbitrary (A) bulbs are the most widely used and thought of when it comes to household lighting. These bulbs work well for a variety of applications, such as ceiling lights, lamps, vanity lights, kitchen lights, closet lights, porch light fixtures, and so many more.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

A15 bulb: 15/8 = 1-7/8″ diameter

A19 bulb: 19/8 = 2-3/8″ diameter

A21 bulb: 21/8 = 2-5/8″ diameter

A25 bulb: 25/8 = 3-1/8″ diameter

Most common base types:

Globe (G) bulbs have a full, round shape and are available in various sizes. They can be used for many applications throughout the home, such as foyer lights, kitchen lights, chandeliers, and ornamental fixtures. The most common type is the large G30 bulb, which is used in bathroom and makeup vanities.

Depending on the bulb, numbers in each code can refer to the bulb’s diameter in one-eighths of an inch or in millimeters.

G11 bulb: 11/8 = 1-3/8″ diameter

G14 bulb: 14/8 = 1-3/4″ diameter

G16/G50: 16/8 = 2″ diameter

G60: 60 millimeters = 2-3/8″ diameter

G25/G80: 80 millimeters = 3-9/64″ diameter

G30: 30/8 = 3-3/4″ diameter

Most common base types:

All of the bulbs in these groups resemble the shape of a candle flame and are often referred to as candle bulbs. Conical (C) bulbs are shaped like a cone. Conical angular (CA) bulbs are shaped like a cone but have a bent tip. Blunt-tip (B) bulbs are very similar to C-type bulbs but have more of a torpedo or bullet shape. These bulbs can be used in chandeliers, wall sconces, pendant lights, night lights, decorative light strands, holiday light strands, and other decorative home lighting applications.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

B10 bulb: 10/8 = 1-1/4″ diameter

CA10 bulb: 10/8 = 1-1/4″ diameter

C7 bulb: 7/8 = 7/8″ diameter

C9 bulb: 9/8 = 1-1/8″ diameter

C15 bulb: 15/8 = 1-7/8″ diameter

Most common base types:

BR stands for bulged reflector. Traditionally, the inside surface of an incandescent BR bulb is covered in reflector material that is used to gather and cast a wide beam of light away from the bulb. LED BR bulbs don’t require the reflector material. These bulbs can have a frosted, clear, or patterned dome-shaped lens that diffuses light and provides a gradual fade into nonilluminated areas. BR bulbs also produce less shadows when compared to PAR bulbs. They’re a bit longer than PAR bulbs and tend to protrude from light housings but are used in similar applications, such as track lights, recessed lights, display lights, or can lights.

BR20 bulbs are often referred to as R20 but have the same characteristics of other BR bulb types. The R stands for reflector.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

BR20/R20 bulb: 20/8 = 2-1/2″ diameter

BR30 bulb: 30/8 = 3-3/4″ diameter

BR40 bulb: 40/8 = 5″ diameter

Most common base type:

Multifaceted reflector (MR) bulbs are small in size with a reflective, faceted interior. The facets create a concentrated beam of light that can be displayed in a narrow spot or wide flood beam pattern. Because of the directional light they provide, MR LED bulbs don’t require the facets but often still have them. These bulbs are available in a variety of colors and can be used for many applications, including track lighting, recessed lighting, desk lights, and display case lighting. Many MR bulbs operate on low-voltage wiring systems, which makes them great for outdoor and landscape applications such as driveway lights, path lights, gazebo lights, paver lights, and malibu lights that have weatherproof housings.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

MR11 bulb: 11/8 = 1-3/8″ diameter

MR16 bulb: 16/8 = 2″ diameter

Most common base types:

Tubular (T) bulbs come in a variety of lengths and widths. Depending on their size, these bulbs can be used in applications ranging from chandeliers, wall sconces, and pendant lights to basement and garage troffer light fixtures.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

T7 bulb: 7/8 = 7/8″ diameter

T8 bulb: 8/8 = 1″ diameter

T10 bulb: 10/8 = 1-1/4″ diameter

T14 bulb: 14/8 = 1-3/4″ diameter

Most common base types:

Do you find that your home’s indoor air is extremely dry? Are you frustrated by dry skin and sore throats during the winter time? Do you need something a bit more comprehensive than the small humidifiers that you can buy at the local hardware store? If you own a central air unit/furnace combo or a heat pump, then you also have a network of ducts installed in your home. A whole house humidifier may be just what you need to ensure that your air is optimized when it comes to the humidity level. Dry air can disrupt your comfort and aggravate health issues.

Mr. Electric® wants to make sure everyone is ready for the fall and winter months in case any weather-related disasters occur.  The importance of having alternate reliable energy when the need arises cannot be stressed enough. Electricity is the lifeline of many local businesses, hospitals and city buildings, and the amount of electricity usage in households is often taken for granted.

Generators propose a great solution when temporary power is needed, but they also require special care and attention to detail for safe operation and maintenance. Follow these tips to stay safe while operating permanently placed and portable generators.

Always operate generators outside in well-ventilated areas and away from windows, doors and vents. Enclosed or partially enclosed areas, even with ventilation, can result in CO poisoning.

“One generator produces as much CO as hundreds of cars. CO from a generator is deadly and can incapacitate and kill you within minutes.”

- Consumer Product Safety Commission

Plugging the generator into a wall outlet, also known as backfeeding, can pose an electrocution risk to utility workers as well as other homeowners and businesses served by the same utility transformer.

Mr. Electric licensed service professionals will be able to install a transfer switch, which will prevent a back feed in electrical current.

Before refueling, always turn off the generator and allow time for it to cool off before refueling. Continuous operation heats up the generator and any fuel spilled on hot engine parts could ignite.

Store fuel away from any fuel-burning appliance and outside of living areas in properly labeled, non-glass containers.

Always make sure the generator is kept dry during use, and dry your hands before touching it. Operate the generator under an open, canopy-like structure.

Never use the generator in wet or rainy weather or manipulate the electrical components if you are in standing water. Correctly storing and maintaining generators will prolong the life of the unit.

Being aware of the inherent hazards of electric generators will help prevent harmful situations. These tips from Mr. Electric will keep homeowners safe while operating permanently placed and portable generators.
