The vast majority of people are under the impression that there is only one type of recessed lighting: recessed lights. However, these light fixtures actually come in a variety of different types. If you're not sure what the differences are, it can be stressful to discover that there are indeed differences once you're out shopping for them. Plus, let's face it, the teenager who works there on the weekends doesn't know the difference either, no matter how hard he tries to sell you on the idea that he does! Here's the low down on different types of recessed light fixtures.
Differences in Name
As expected, recessed light fixtures can go by a variety of different names. This includes canister lights, in-ceiling lights, recessed lights, can lights, pot lights, pots and so forth. Remember that these are just different names and typically does not mean anything other than that is what the manufacturer has chosen to name the product.
Different Types of Recessed Light Fixtures
Time to get down to the nitty-gritty truth of recessed lights: there are four classifications currently for recessed light fixtures.
The first type is known as insulation contact, also referred to as 'IC.' Insulation contact recessed light fixtures are those that are approved for contact with insulation, simple, right? Though this is true, these ceiling fixtures also need to be attached to the ceiling supports of the home. This means that they are only useable for homes that are just being built, they're not suitable for installation in existing homes because you'd have to remove the entire ceiling just to install them. Furthermore, IC rated recessed light housings are only rated up to a 75 watt maximum bulb. Put in anything higher in wattage and you could easily end up with a fire.
For existing homes, a type of IC canister exists that falls under the 'remodel' category. This means that these light fixtures are suitable for installation in an existing home. Much like the IC housings meant for new construction, these must be installed in a way that they come in contact with insulation as these fixtures have been designed to work together with the insulation to prevent issues. So keep in mind that you cannot install insulation contact canisters in a space where no insulation is present, as this can create issues.
The last two types are meant for non-insulation situations. As expected, there are recessed light fixtures meant for new construction as well as the recessed ceiling fixtures that can be installed in a 'remodel.' It is extremely important that you do not install these light fixtures in a way that they will come in contact with insulation, as they are not rated for or designed for use with insulation and therefore will quickly cause a fire.
Final Notes
The most important difference when choosing recessed light fixtures for your home is of course, whether they are meant for new construction or remodeling and that they are rated for use with or without insulation. Once you've determined what you need, you will find that each variety also comes in a number of different sizes, typically available in 4, 5 or 6 inches in diameter. Some speciality companies also offer smaller recessed light fixtures ranging from 2 to 3 inches, but these may not be available depending on what type you require.
