LED Color Changing RGB Recessed Installation Guide


At under 4" tall, our 3.5" round RGB and RGB + White LED recessed light can fit into tight spaces that a traditional recessed can light can’t, such as ceilings with ductwork/piping/obstructions, hot-roof ceilings with limited vertical clearance, and tight soffits.

These lights feature an easily adjustable LED face that can be pointed straight downward, making them compatible with sloped ceilings (up to 6/12 pitch or 26.57°). Our slope ceiling recessed lights also make perfect art spotlights or wall accent lights, as they can also be installed in flat ceilings and adjusted to point at walls, artwork, or sculptures.
Use the RGB Color Changing capability of these unique lights to create a truly unique aesthetic for your space.

Before You Begin

We know how boring it can be to read instructions, so we’ll keep this installation guide as short and sweet as possible. Before you begin with your installation, be sure to fully read the installation instructions. This installation guide is intended to be a helpful supplement, containing useful tips and pointers that will help to ensure a perfect installation, save you time, and ensure your safety. It is important that you install this product (and all other electrical products) in accordance with the National Electric Code (NEC) and all applicable local building and electrical codes for your area. If you are unfamiliar with the NEC, your local building/electrical codes, and/or the proper installation methods for electrical devices, you should hire a qualified and licensed electrician to do the work for you.

Before doing any electrical work, always disconnect power at the fuse or circuit breaker.

Planning your layout

Most electricians space recessed lights equally apart from each other forming a grid pattern on the ceiling. The distance between each light generally depends on the LED wattage of your light. Here are a few rough rules of thumb for spacing when using the lights as primary lighting (if you are using the lights as accent lighting or you have other lights in your room, you can space them further apart):

LED Wattage Incandescent Equivalent Recommended Spacing
3 Watts 25 Watt 3W fixtures are generally used for accent/cabinet lighting and are not usually used as general room lighting. If you do use them as general lighting, you’ll want to space them roughly 2-3 feet apart.
6 Watts 50 Watt 6W fixtures are generally laid out in a grid such that they are 2’- 3’ off each wall and 4-5’ apart from each other.
9 Watts 65 Watts 9W fixtures are generally laid out in a grid such that they are 3’ off each wall and 5-6’ apart from each other.
12 Watts 75 Watt 12W fixtures are generally laid out in a grid such that they are about 4-5’ off each wall and about 6-7’ apart from each other.
18 Watts 125 Watts 18W fixtures are generally laid out in a grid such that they are 5-6’ off each wall and about 8-10’ apart from each other.

Important Considerations
This fixture is suitable for use in dry or damp locations
When using this fixture in damp locations, it must be installed in a ceiling where it is protected moisture by a roof or floor above.

Wiring Connections

New Construction
For new construction applications using sheet rock ceiling, we recommend using aspectLED’s Rough-In Bracket/Plates.

Before installing ceiling, layout your light locations and securely fasten the rough-in plate to your joists at each light location. The rough-in brackets have convenient slots in them allowing you to make minor adjustments to the bracket positioning after you’ve mounted them. Run wire (following the conventional or low clearance installation instructions below) to each of your light locations before drywalling.

Before drywalling, double check the location of each light. Once you’ve drywalled, you won’t be able to adjust the positioning.

Instruct your drywallers to cut-out the holes for each light using the rough-in bracket as a template. Then, once drywall is finished, install your lights by following the remainder of the low voltage or line voltage installation instructions below.

  • Determine a suitable location to install your fixture, power supply, and color changing controls.
    This will include suitable wire installed between the power supply, the LED light fixture, and any controls. It is important to choose the correct wire for the specific application, this is dependent on voltage drop, amperage rating, and environment. Please consult a voltage drop and wire sizing chart to determine adequate wire size. Using the incorrect wire size will damage your products! If installing wiring in a wall or ceiling, always use in-wall rated wiring.

  • Cut the hole that you’ll install the fixture into.
    Begin by drawing the appropriately sized cut-out hole on your ceiling using a pencil. Then, using a jab saw (or a drill with a hole saw), make a hole in your ceiling that is the correct size and shape for your light.

  • Run appropriately sized low voltage wire from your central driver location to each light location.
    You can wire these in series from the power supply to your first light, from your first light to the second, to the third, etc, as shown in System Diagram. But, we do not recommend exceeding 80 watts on a single wire run.
    • If you choose to run your own low voltage wire from the driver box to each light, we always recommend using a 2 conductor stranded wire with a voltage rating of at least 300V.
    • Please consult a voltage drop and wire sizing chart to determine adequate wire size. Using the incorrect wire size will damage your products! If installing wiring in a wall or ceiling, always use inwall rated wiring.
    • You’ll need a little bit of slack in your wire at the light location to allow you to install the light (and to remove it if you ever need to), so be sure to leave about 6-8” of wire sticking out of your hole at the light location. Also, be sure to leave some extra wire at the driver/junction box location, so you have enough slack to neatly organize your wires.

  • Mount and connect your power supply.
    At the location where you’ve decided to install your power supply, securely mount your power supply and run your electrical wire from the controls location to the power supply. Be sure to check your local code for which type of wire is required.

  • Connect your low voltage.
    At each light location, connect the incoming low voltage wires to the LED driver for each light fixture using wire nuts or crimp connectors.

  • Install your light into the hole
    Gently lift upwards on the retention clips on each side of your fixture and carefully push it into the cut-out hole. Once the light fixture is in the hole, allow the spring-loaded retention clips to come down, holding the light firmly in place against the drywall or ceiling material. The maximum ceiling material thick that these lights are designed to work in is 1.25".

  • Once you’ve finished, double check all connections and turn on power to your circuit.
    Test functionality of your installation. If you experience issues, see the trouble shooting guide on page 12, or contact technical support at (888) 503-1317 option 3 or

  • Congratulations! You’ve successfully completed the installation process.
    Once your light is installed, your project is finished. Now is a great time to take a moment to sit down and enjoy your favorite beverage while giving yourself a pat on the back for a job well done.
