Canless recessed lighting, also known as wafer-thin LED lights or slimline recessed lights, has become increasingly popular due to its sleek design and energy efficiency. Compared to traditional downlights, canless recessed lighting fixtures are easy-to-install and require minimal modifications to the ceiling. In this article, we will guide you through the process of installing canless recessed lighting.

How to Install Canless Recessed Lighting

Tools Required

Before you start installing canless recessed lighting fixtures, gather these essential tools:

  • Canless Recessed Light Fixtures
  • Wire Strippers
  • Voltage Tester
  • Screwdriver
  • Drywall Saw (if necessary)
  • Drill & Drill Bits
  • Fish Tape

Step-by-step Guide on Installing Canless Recessed Lighting

Step 1: Cut a Hole in the Ceiling

To install canless recessed light fixtures, you’ll need to cut a hole into your ceiling for each fixture. Determine where you want to place your fixture(s) using a stud finder and mark it with a pencil. Use a drywall saw or drill with an appropriate bit size to create the hole in the marked area.

Step 2: Install Junction Box for Wiring

With a voltage tester tool make sure there is no electric current running through that circuit before starting any electrical work.
After cutting out holes for placement of desired light location install junction box from one side of room’s ceiling rafter then fish tape wire from either second floor above or attic space then after pulling wires do proper fittings.
Remember that every connection needs proper insulation covering on it.

Step 3: Connect Fixture Wiring

Connect individual wires coming out from junction box with respective wires within each fixture according color code.(black black / white white .etc ) keeping proper insulation covered over them .
Then carefully fit back main body chassis by rotating it gently clockwise.

Step 4: Place Fixture in the Ceiling

Insert your canless recessed lighting into the opening you created, and carefully attach it to the ceiling with screws. Ensure that each fixture is flush with the ceiling.

Step 5: Testing

After fitting all downlights on their respective locations if everything went in correct order. Finally test them once before turning off any electric source from main board by putting a small amount of electricity supply of this circuit.

Advantages of Canless Recessed Lighting

If you are looking for a way to brighten up your home while also saving energy, canless recessed lighting may be the perfect solution for you. This type of lighting comes with many advantages over traditional incandescent lighting. In this article, we will explore some of those advantages.

Energy Efficiency

One major advantage of canless recessed lighting is its energy efficiency. Traditional incandescent lights consume a lot more energy compared to LED lights which are typically used in canless recessed lighting fixtures. Given that these lights operate for hours every day, it’s important to choose energy-efficient options to keep your electricity bills low.


Canless recessed light fixtures emit little or no heat when compared with other forms of lighting such as halogen bulbs or fluorescent tubes, making them safer than their counterparts and suitable around children and pets.


Canless recessed light fittings come in various colors and styles that cater to different tastes and decor choices There is one available color temperature option called ‘warm white’, which creates an inviting look and feel within any living space without necessarily feeling too sterile or cold.

Ease of Installation

Compared to traditional incandescent bulbs, which may require electrical expertise due to varying voltage levels, canless downlights often come pre-wired, making installation a breeze with just a simple plug-and-play system.

If you’re looking for an effective way to save money on your energy bills while keeping your living spaces well-lit and safe, consider switching from traditional incandescent bulbs to canless recessed LED lights.

What type of wiring is required for canless recessed lighting installation?

Answer: Canless recessed lighting requires a dedicated circuit with wiring rated for at least 15 amps. The wiring should be run from the junction box to the light fixtures using non-metallic sheathed cable (NM).

Can I install canless recessed lighting in an insulated ceiling?

Answer: Yes, you can install canless recessed lighting in an insulated ceiling, but you will need to use insulation contact (IC) rated fixtures that are designed to be installed in direct contact with insulation material.

How do I determine how many canless recessed lights I need for a room?

Answer: To determine how many canless recessed lights you need for a room, measure the length and width of the room and multiply those numbers together. For example, if your room is 10 feet by 12 feet, it has an area of 120 square feet. For general ambient lighting, divide this number by four to get the recommended wattage needed (i.e., 120 ÷ 4 = 30 watts). Divide this wattage by the wattage of your chosen LED bulbs to get the number of fixtures needed (i.e., if your LED bulb is 10 watts each; then you will need three fixtures).
