Recessed lights are installed in a drop ceiling with pot lights
Recessed lights can be installed in a drop ceiling, and this type of lighting is a popular choice for offices, basements, theatres, and schools. This is because it offers an attractive, sleek, and unobtrusive look, and is often used to conceal air ducts or pipes. Recessed lights are also known as pot lights, can lights, or downlights.
Before installing recessed lights, it is important to take safety precautions, especially when electricity is involved. You should also ensure that you are using the right fixtures for your installation, including whether you need IC-rated recessed lights. If you are uncomfortable working with electricity and wiring, it is best to hire an electrician to make the connections.
To install recessed lights in a drop ceiling, you will need to purchase a recessed lighting kit, which includes the lights, trim, and installation hardware, as well as instructions for installation. First, use graph paper to create a map of your room and plan where your lights will go, taking into account ceiling height, brightness, and focal points. Next, cut a hole in the ceiling tile and mount the light housing, connecting the wiring and securing the trim. Depending on the type of light and wiring in the ceiling, additional installation steps may be required. For example, you may need to install wire supports or suspension clips to support the weight of the lights. Finally, insert the light bulb into the recessed lighting housing and attach the trim ring to the rim of the light can.
In the past, recessed lights would include a metal box with a built-in junction box, with the light unit inserted after drywall. With the advent of ultra-thin LED lights, the electrical rough-in process has changed, and it is now common to rough in the wire location, leaving slack in the ceiling for the electrician to cut the hole, pull down the cable, and wire the driver to the cable.

The electrical rough-in must be done before putting up drywall
When installing recessed lights, it is essential to understand the electrical rough-in process and why it must precede drywall installation. Recessed lights are a great way to provide functional lighting that seamlessly blends into the ceiling. However, the electrical rough-in for these lights can be a complex process, and careful planning is necessary to ensure safety and compliance with local codes.
The electrical rough-in refers to the preliminary work done to prepare the electrical wiring and connections for recessed lights before the drywall is installed. This process typically includes installing the wiring, junction boxes, and, in some cases, the light housings. It is crucial because it ensures that the electrical components are safely and securely installed, providing a foundation for the finished lighting fixtures.
One key aspect of the electrical rough-in is addressing the wiring. The wires must be run from the breaker panel to the locations of the recessed lights. Since the drywall will conceal a portion of this wiring, it is essential to complete this step before installing the drywall. Leaving a tail of wiring at the location of the first light can be a good practice, ensuring that the wires are easily accessible during the final installation.
Additionally, the electrical rough-in may involve installing junction boxes, which house the electrical connections for the lights. These boxes must be secured and properly installed to meet local codes and safety standards. In some cases, the light housings themselves may need to be installed during the rough-in phase to pass inspection. This is especially true for ultra-thin LED recessed lights, where the junction box and LED are unitized, requiring careful consideration during installation and future maintenance.
Completing the electrical rough-in before putting up drywall is essential for several reasons. Firstly, it ensures that the electrical work is done correctly and safely, reducing the risk of fire hazards or electrical issues. Secondly, it allows for rough-in inspections, where inspectors can verify that the electrical components meet local codes and standards. Finally, it provides a solid framework for the drywall installers to work around, ensuring that the lights are properly positioned and that the drywall cutouts are accurately sized and placed. By following this process, homeowners and professionals can ensure that their recessed lighting installations are safe, functional, and compliant with all relevant regulations.

Remodel cans and new construction cans are the two types of pot/can light fixtures
Recessed lights, also known as can lights, downlights, or pot lights, are a popular choice for contemporary homes due to their low-profile design and ability to emphasise the home's geometry. These lights are installed into a ceiling, wall, or other surfaces, with the light bulb concealed within the surface.
When it comes to installing recessed lighting, there are two main types of pot/can light fixtures: remodel cans and new construction cans. The type you choose depends on the specific requirements of your project, such as your preferred method of sheetrocking and the inspector's preferences.
Remodel cans, also known as "cut-in" or "drop-in" cans, are typically used when you cannot access the space above the ceiling to run the wiring. The housing for a remodel fixture is usually supported by pushing metal clips through the housing onto the top of the ceiling, which can be drywall or plaster. This type of fixture is often chosen when there is limited access to the ceiling cavity, making it a common choice for retrofit installations.
On the other hand, new construction cans are used when you have access to the space above the ceiling where the fixture will be located. These fixtures are supported by screwing or nailing the fixture's frame directly to the ceiling joists. New construction cans are generally less expensive and offer a wider range of trim options compared to remodel cans.
It is important to note that electrical rough-in work, including wiring for pot lights, is typically completed before sheetrock or drywall is installed. This allows for easier mounting and facilitates the inspection process. However, it is always recommended to consult with a qualified electrician and follow local building codes and regulations to ensure safe and proper installation.

Ultra-thin LED lights have free-floating junction boxes
Recessed lighting, also known as can lights or downlights, is a type of lighting where a light fixture is installed into a ceiling, wall, or other surface, with the light bulb concealed inside the surface. It is a popular choice for those looking to brighten up their space, as it provides cost-effective energy savings and adds value to homes.
One of the more recent additions to the recessed lighting market is the ultra-thin LED light, which has no housing and is therefore extremely slim. These lights are a good choice for those looking to save energy and money, as they are cool to the touch and highly energy-efficient. The ultra-thin LED lights also have free-floating junction boxes, which means they don't take up insulation space and can be more easily installed in various spaces.
The free-floating junction boxes of these ultra-thin LED lights have sparked some debate among electrical professionals. Some inspectors have claimed that the junction boxes need to be secure, while others argue that if they are listed products, they are already approved for use. The accessibility of these junction boxes is also a point of discussion, as some believe that having them accessible through the light opening is more user-friendly, especially in remodelling situations with no attic access.
When installing ultra-thin LED recessed lights, it is important to follow the instructions and labelling provided by the manufacturer. The installation process typically involves cutting a hole in the ceiling, connecting the junction box to the cable, and using a spring clip to fix the light in place. This type of lighting is suitable for various spaces, including kitchens, living rooms, and bathrooms, and can be installed in as little as a few minutes.
