When winter temperatures dip below freezing, families across the country fire up their furnaces, boilers, space heaters, woodstoves and other heating devices to beat the cold and keep their homes warm and snug. Unfortunately, the very appliances that ward off the winter chill can put you in danger of a house fire. January is the leading month for residential home fires, accounting for 21 percent of the total, according to the U.S. Fire Administration, and home heating is the second leading cause of all fires, after cooking.

Don't let your home become a statistic. Take these steps to reduce your risk of a house fire:

Clean your chimney: Creosote can build up from normal fireplace usage and clog the chimney from below; the chimney can also be clogged from above if debris falls in or if the chimney itself starts to deteriorate. Either way, it's a danger. Make sure your chimney is cleaned each year before using it.

Get your HVAC equipment serviced: You should have a technician pay a visit once a year to make sure your furnace and other equipment is in good working order. Your service professional can perform routine maintenance, repair any issues and instruct you on how to maintain your unit. Some maintenance, like replacing air filters monthly, you can do yourself in compliance with manufacturer instructions.

Careful with that space heater: Space heaters can be a convenient way to heat a small area, but they come with several caveats. Be very wary of liquid-fueled heaters -- older models shouldn't be used indoors at all, although newer models can be safe as long as you diligently follow all instructions regarding fueling and operation. Even electric heaters can cause problems, because they draw a lot of power which can overload the circuits in older homes. If you decide to use a space heater, make sure it is in no danger of tipping over, and never leave it running unattended. Space heaters account for one third of all heating fires, according to the National Fire Protection Association, so be careful.

Keep combustible material away from heat sources:  Leave a few feet of clearance between your stove, space heaters, vents, radiators and other heat sources combustibles like furniture, carpet or curtains.

Don't thaw pipes with a blowtorch: Frozen pipes are a serious problem, and thawing the ice is critical to avoiding a burst pipe and the expensive damage that can accompany it. You have a number of good options to heat the problem area -- a hair dryer, heat lamp, space heater, hot towel or specialized heat tape will do the trick. Avoid open flames, which create a fire hazard.

Test your smoke detectors: It just takes only a moment to ensure your smoke detectors work. If you do have a fire, they could save your life.

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:

Jewelry doesn’t sparkle and shine on its own – the reason a gem looks radiant is because of the way it reflects light! That being said, lighting is integral to retail design in a jewelry store. You want your displays to entice customers and show off your products in all their brilliance! Hopefully, we can help. This post will lay out options for various jewelry lighting displays.

puck lights to call attention to individual pieces, as seen in the photo to the right. Puck lighting above jewelry creates beautiful silhouettes and puts a spotlight on each piece.

If you love the look of evenly illuminated in-wall shelving displays, there is a way to avoid the spotlight effect. For a more subtle glow, install light fixtures on the inside edges of your shelves. See Xenon Low Voltage Light Strip or any of our

You’re showing off your most valuable items in the counter-style showcase, so it’s important to get the lighting right. However, make sure the actual light fixtures do not become focal points.

With a glass showcase, you need to integrate the lighting so that your display will shine, and so that it’s not blocked in any way by wires or lamp heads. The best way to do this is to install thin lighting strips inside the showcase, just below where the edge of the counter is. You can see an example in the photo to the right.

Our Your window display can be the number one determinant of store traffic. Like the counter showcase, it’s ideal if the light fixtures aren’t visible at all here so that your most alluring items take center stage.

You will likely have wall space to work with on all four sides of the window display, so it wouldn’t be too difficult to align microfluorescent fixtures against the edges for even illumination.

Depending on what types of items you are featuring, you might want to incorporate some spot lighting as well. You could use an adjustable adjustable recessed lights in the ceiling above the window display.
