Different kinds of recessed lighting

Some canned lights are designed specifically for certain conditions. Most canned lighting fixtures are easily installed between ceiling joists. Other canned lights are designed to replace existing ceiling fixtures by simply slipping into holes that have already been made and using the existing wiring. When working with electrical components such as these, you also want to make sure that the fixtures that you choose are rated for use near insulation (IC housing rated) whenever ceiling insulation is present.

Deciding where to place recessed light fixtures

When placing your canned lighting fixtures, there are a few things that you might want to keep in mind. Placing your light fixtures too closely together down the length of a room can give a very sterile and commercial type look to your room. A general rule of thumb to remember when deciding on the spacing of your lights is to match the size of your recessed lighting fixtures to how close together they can be installed. For example, 4-inch fixtures should generally be placed at least 4 feet apart and 6-inch fixtures about 6 feet apart. Overhead lights that are intended to be used as task light for an activity such as reading, should be carefully placed overhead so your head and shoulders will not block needed light.

Sizing canned lighting fixtures

There are typically three sizes available to you when you are looking for a canned lighting fixture. These sizes are four, five, or six inches in diameter. These sizes will generally come with standard line voltage, low voltage halogen, or fluorescent fixtures. In general, the 6-inch fixtures are used in tall entryways or two-story hallways where a stronger fixture is needed for sufficient light. The smaller 4-inch sizes work better in smaller spaces and have a sleeker, contemporary look that draws less attention to them as they are generally more noticeable in a room.

Choosing the right light bulbs

There are several types of light bulbs available to you depending on the fixtures that you have chosen and the lighting needs that you have for a particular space. Incandescent bulbs, or "A" bulbs, are inexpensive and good for general lighting tasks. The "R" bulbs are most common type of light bulb for canned lights. The "R" bulbs have a reflective surface included on the back of the bulb. Halogen bulbs offer a clean white light, and are available in a variety of lighting types and sizes. Low voltage halogen bulbs have a long life and put out more light than incandescent bulbs, but require the use of transformers and special low voltage housings making them a less common choice for do-it-yourself home remodelers.

Cautions

While upgrading from fluorescent to canned lighting is a good way to update the look of your home and improve the lighting conditions therein, any electrical project has its dangers. Make sure that you educate yourself beforehand. Get advice from an experienced electrical salesperson on what parts are needed for your space. In some local areas, you are required to obtain building permits to upgrade or install recessed lighting.
