Let There Be Light

When decorating a room or building a new home, one consideration is the type of light fixture to use. As you consider fixtures, think about the type of light you want it to emit, and where it will be used. You wouldn't use the same type of bulb in a basement or kitchen that you would in a bedroom. Here are the basic types of light bulbs, and the best places to use them.


Incandescent lights are the most common and the most familiar. Electric current is run through a filament which produces light. This type of bulb is least expensive, provides a soft light, and is suitable for use in any room.


Halogen lights produce "white light" and are the closest to natural light. They're more energy efficient than incandescent bulbs, but also burn hotter. They're a good choice for under cabinet light, pendant lights, or pot lights. Don't use your bare hands to change halogen lights. Oil from your hands can create uneven heating and cause them to explode.


Florescent lights are best used in large areas such as a basement or an attic. The light has blue undertones, which can be too harsh or bright in small spaces. Florescents come in warm and cool tones, or special colors. They burn longer than incandescent bulbs, but aren't as versatile.


CFLs, or compact florescent bulbs, burn 10 times longer than incandescent bulbs and use one quarter of the energy. Unlike traditional florescent bulbs, CFLs are interchangeable with incandescent bulbs and don't have the harshness of their predecessor. They do contain a small amount of mercury so follow directions for use and disposal.


LEDs, or light-emitting diodes, are even more efficient to use, but they provide directional not diffuse light and aren't good for large spaces. Grouping LEDs in clusters creates a more diffuse effect, but they cost five to six times more than CFLs.


Whatever fixture you select, be sure to choose the bulbs carefully to get the best result. Consider the room and its function, the wattage capacity of the fixture, and the cost. JM Mullen Electrical Service can install any light fixture in your home or business. We continually educate our staff about new technology and can give you valuable advice. Call us today for help with your lighting needs.

Keep Young Children Safe Around Electric Outlets

Children and toddlers are curious about everything and they spend lots of time on the floor where electric outlets are located. If they can't put things in their mouths, they'll try putting their fingers into interesting looking places. Take advantage of the many options available to protect the little people in your home.



Tamper Resistant Receptacles


Believe it or not, most accidents involving children and electricity happen when adults are in the same room. Since 2008, tamper-resistant receptacles are required for all new or renovated homes. These receptacles have a spring-loaded shutter that closes the electrical slots when they're not being used. If you have a new home, or if you recently renovated your home, don't assume that the correct receptacles were installed. The outlets should have the letters "TR" or "tamper-resistant" printed on them.



Outlet Covers


If your home isn't new, and you're not planning a renovation in the near future, plastic receptacle covers will do the trick. These plastic covers have been on the market for years and will keep little fingers out of the outlet. One of the biggest challenges with these covers is remembering to put them back in the outlet when finished using it. It's an inexpensive way to add safety to your home.



Sliding Outlet Covers


Sliding outlet covers, or self-closing outlet covers, are a bit on the pricey side, but if you can afford them, they're worth the price. When the outlet isn't in use, the cover snaps back automatically.


There are other simple ways to safeguard babies and toddlers against electrical shock. When using extension cords, keep them hidden away and out of reach as much as possible. Avoid hanging cords, which pose a double hazard if there's an item that can fall if the cord is pulled. If you only need them for a short time, remember to promptly remove them when you're finished. Additionally, use furniture to block receptacles where possible.


JM Mullen can help you do a safety inspection of your home and provide solutions to keep your family safe. We monitor the latest technology and can keep you informed about new products. Contact us today for a free appointment at 410-266-6316 or online at www.jmmullenelectric.com.

Making Modifications Inside Your Home

With so much information on the internet and at specialty DIY stores, such as Home Depot, many people feel confident making changes they think are fairly simple. Remodeling projects for kitchens and bathrooms usually involve hanging cabinets or hardware. If you're going to drill into the walls of your home or business, you'd be wise to call in an electrician.

The Differences Between Residential and Commercial Electrical Services

Electrician, LightingsSterling Optical Commercial Electrical Work

There are some significant differences between residential and commercial electrical services, and not every electrici


an is qualified to do both types of work. Differences between commercial and residential services include the different levels of energy demands, the different grade or quality of materials, and the different environments where wiring is installed.

Residential wiring is typically plastic sheathed wiring and doesn't use conduits, even though they can be used. In commercial construction, conduit is always used. The power from the utility company varies greatly between residential and commercial applications. Homes use single-phase power that has two 120-volt wires (or legs) and a neutral wire. Commercial buildings use three-phase power which consists of two 120-volt legs, and one 208-volt leg and a neutral wire. Commercial electrical applications require power demands for larger electrical units and three-phase power enables power to flow more smoothly to needed areas.

The quality, or grade, of electrical materials also differs between residential and commercial buildings. Commercial materials are more resistant to heat, corrosion, and chemical exposure. They are subject to different standards, and are governed by different codes. Some commercial buildings, such as hospitals, need a secondary or backup source of power with the ability to withstand more demanding usage.


While homeowners may consult with an electrician when undertaking a major remodel, commercial electricians are more likely to confer with architects, designers, and contractors in the course of their work. They look at a project from a broader point of view and may provide detailed drawings and plans for electrical installations.


There are also differences in the electricians who are qualified to work on commercial versus residential buildings. Residential electricians have to be licensed by local and state agencies. Electricians who work in the commercial space are not only licensed, but have to complete a commercial electrician apprenticeship program in order to get their certification. They do some of the same jobs as licensed electricians, but they also take on more sophisticated and larger scale projects.


JM Mullen Electrical Services are experienced at new commercial construction, renovations, and have worked on projects such as an indoor soccer fields, religious buildings, and restaurants. Contact us today to find out more about our commercial services and qualifications.
