Earlier this month, we discussed the signs you should notice that tell you the time for electrical rewiring in Fairfax, VA is near. Keeping an eye out for any indicators is important, but you also need to consider what types of rewiring would be beneficial for your home. If you notice your home has one too many extension cords, then it’s certainly time to get rewiring service that will eliminate over reliance on extension cords in favor of an alternative. Or maybe you notice your home is still equipped with dated aluminum wiring, which will require a different rewiring service altogether.

Unsure of what type of rewiring you need and for what purpose? Well, here’s a general overview of the 4 most common types of rewiring our team handles:

Understanding common household light bulb shapes, sizes, and styles is important whether you’re converting outdated incandescent fixtures into energy-efficient ones or using LED bulbs for new-construction applications.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:

We are all quite aware that ever since B. Franklin decided to go outside with his kite in the midst of a thunderstorm, this thing called electricity pretty much rules our life. To understand this, you must recall what it felt like that one time your power went out for the entire day. This meant nothing worked, no computer, no refrigerator, no television and not to mention no Wi-Fi!

We know that electricity plays an important role in people’s lives from the moment they wake up to the time they go to sleep. Since electricity is always available, people usually don’t think twice about how important it is in terms of complementing their lives. Electricity makes our lives comfortable. People are so accustomed to using electricity in a range of activities. When at home, electricity is used for lighting, air conditioning, , cooking food, using computers, watching TV, and operating other appliances and devices. With the help of electricity, people function better at night because electricity has enabled them to see even through the dark. Gee, thanks Benjamin Franklin!

However, there might come times when you should find yourself encountering problems with the wiring or any other electrical work. Often, homeowners decide to feed their ego when they think these are problems they can easily fix on their own, which is highly untrue. Whenever someone who lacks knowledge, experience and training to deal with electrical issues deals with electrical issues, it has catastrophic results.

Before you decide to put your hand inside the fuse box, you must know how power works, how it moves and what could happen should you be electrocuted. I am guessing these are things you didn’t think about as you didn’t even consider the possibility of something going wrong. Don’t fret, as you can easily call in a certified electrician.

Underrated as they may be, they are the reason the wiring in your house doesn’t go bonkers and burns your house. Certified electricians not only know their work inside out but they also adhere to the best practices and follow the guidelines and rules laid down by the state. You can rest assured they will deliver a level of service that ensures peace of mind for you.

Remember José from two blocks down? He hired an electrician who wasn’t certified and he had to get whole new electrical wiring done for his house at a great cost. Do you want to be that guy?

To conclude, there are numerous benefits of hiring a certified electrician for any electrical work you have around the house. Even the government trusts their capability, so why shouldn’t you! So, before you call the first electrician you find in the directory, ask whether or not they are licensed.

Now when most people would be shy asking, and most electricians offended when asked for a licence, you should know it is within your rights to ask for it. Should something go wrong, you are liable legally while certified and licensed electricians take full responsibility for their work and the leading ones guarantee the quality of their work. Now, think about that the next time you feel shy or reserved asking for a licence when hiring an electrician for electrical work. It will go a long way, my friend.
