There are two main components to recessed lighting: the housing and the trim. While picking the right trim is largely based on your personal taste, picking the right housing can be a little more technical (you might have to ask your electrician a few questions). Understanding the following is the key to getting the right recessed light:
Remodel or New Construction
In order to pick the correct housing, you will need to know whether to use a "Remodel" or "New Construction" style housing. Although these terms seem straightforward, they are somewhat of a misnomer. "New Construction" housings are appropriate when you have accessible space around where the light is going to be placed. "New Construction" housings are used when: A) You are building in a new space where you have full access to the wall/ceiling/floor without sheet rock or plaster hindering your access to beams, etc., or B) You have access to the space due to an overhead attic, a pop out ceiling panel, etc. The reason you need all this space? "New Construction" housings are bulkier and are installed in between joist beams or onto hanger bars from T-Bar or drop ceilings. Conversely, "Remodel" housings are less bulky and appropriate when you have limited or no access to the space above the new fixture. This is common in apartments or homes without crawl spaces or attics. Remember, even though "Remodel" housings are less bulky, it does not mean that you won’t have to remove sheetrock or make holes in your ceiling to accommodate your new lighting plan.
IC or Non-IC Rated
Understanding whether you need IC or Non-IC rated components is the other critical aspect to picking the right housing. An IC, or insulation contact, rating means that the fixture can come in direct contract with thermal insulation. Conversely, a Non-IC, or non insulation contact, rating means that the fixture can not come in direct contact with thermal insulation and should be kept at least 3 inches from any insulation.
Line or Low Voltage
The final "technical" component decision is to determine whether you want line or low voltage. Line voltage operates directly off of the normal household 120 volt current. No transformer or special dimmers are needed. Line voltage is recommended when you have high ceilings and/or the need to provide general illumination to a room, as you can use up to a 150W bulb. Low voltage is a more energy efficient alternative that uses a 12 volt current instead of a 120 volt current. A special transformer is needed to reduce the voltage and special dimmers are required if you want a dimming feature. Low voltage is recommended when you want to create high contrast and/or are using the recessed lights as a form of task or accent lighting.
The trim is the visible part of the light and hence should reflect your style and the application for which it is gong to be used. First you need to pick the size. Trims come in multiple sizes ranging from 3" to 6" in diameter. The size of the trim is a personal preference; however, larger sized trims are able to produce broader amounts of light. Obviously, smaller trims are less conspicuous and are hence often seen to be more modern and architecturally desirable. Again, while the trim size can be based on your aesthetic, some common applications include: 6" trims are still the mainstay for general residential downlight and wall wash illumination, due to their ability to accommodate a wide range of lamps, wattages, and efficient optics. 5" trims have become popular for task lighting and even general lighting in smaller scale settings. 4" line voltage trims are useful for task and accent lighting with short throw distances and/or lower light level requirements, such as over a bar or counter. 4" low voltage MR16 trims have become the choice for inconspicuous yet powerful precision accent lighting.
After you’ve decided on the size, it is then important to understand the style of trim you want. The appropriate style is largely based on the application and the desired effect you are going for:
Baffle Trim: Baffle trims are the most popular choice of all recessed lighting trims. They are the perfect choice for use in living spaces such as living rooms, dining rooms, dens, bedrooms, etc. These trims feature large uniform grooves which are designed to absorb excess light. Baffles help to reduce glare and are typically offered in two color choices, black or white. Black baffles reduce the most amount of glare from the bulb, while white baffles help to reduce or eliminate the appearance of dark holes in the ceiling.
Reflector Trim: Reflector trims are the preferred choice for use in kitchens, very high ceilings and commercial applications. Reflector trims use a highly polished smooth interior trim to maximize the amount of light produced from the bulb. These trims are available with multiple tints which can aid in either obscuring the bulb from view, or warming the room.
Adjustable Trim: Adjustable trims are used in a variety of applications. They can be used in general lighting, task lighting, accent lighting and wall washing. These types of trims allow the bulb to "float" in the housing and give the user the ability to position the bulb to reach a desired area. A benefit to using adjustable trims is that the housing can be installed off center and the trim can compensate for the housings position and still accomplish the desired lighting technique.
Lensed Trim: Lensed trims are designed to protect the bulb and the interior of the housing from moisture or taking direct hits of water. They are the preferred choice for use in bathrooms, showers, eave lighting and in closets.
Wall Washed Trim: Wall Wash trims are combinations of a directional reflector and a light "scoop" direct light toward the wall. Most scoop wall washers utilize A-lamp or CFL lamps. Higher wattage commercial style scoop wall washers utilize R/BR Lamps. Scoop wall wash trims are generally spaced 20"- 30" from the wall and 20"- 30" apart.
Decorative Trim: Decorative trims have become very popular over the last few years. They combine the ability to provide a pleasing look on the ceiling while utilizing a powerful and efficient low voltage halogen bulb.
Note: Not all trim sizes and styles work with all housings. Therefore, it is important to understand the type of housing you need before falling in love with a certain trim. Similarly, some trims are suited or line voltage and some low voltage; therefore, make sure you understand all of your other constraints before picking your trim.
