Date Published: September 27th, 2020

After seeing a resurgence in the last few years, downlights are slowly making their way back into mainstream interior decor. Downlights are available in both mains voltage (240v) or low voltage (12v). They’re recessed lighting options that can light up large spaces without being too bright, and can be streamlined to make your room look pristine and modern. They’re relatively easy to install, and you’ll only need a few tools for the job. Below is our guide on how to install LED downlights in a ceiling.

Before You Start

Before starting the installation, ask yourself the following questions:

How Many Downlights Do I Need?

In reality, this comes down to personal preference. How many do you feel is needed in the room? Do you need more for certain areas? Kitchens tend to have some over different surfaces such as countertops and oven hobs. It’s best to measure out exactly where you want to place your LED downlights before installation so that you can account for the right number of bulbs.

What Tools Do I Need?

In order to install downlights, you will need the following tools:

  • Chaser
  • Pencil
  • Tape Measure
  • Saw
  • Hand Drill & Hole Saw Drill Bit
  • Small Drill Bit (for your pilot hole)

Can The Original Lighting Circuit Support The Extra Lights?

Circuits are usually on 6-amp circuit breakers (MCB’S). In order to know how many amps can be loaded onto the circuit breaker, use the following calculation:

Total Watts ÷ Voltage = Amps

Please note: do these calculations before starting any installation. Read on to discover how to install LED downlights in a ceiling.

How to install LED downlights in a ceiling

  1. Measure out where you want your downlights to be placed and mark where the central point of the light will be. Once this has been done and you’re happy with the placement, drill small pilot holes into the ceiling.
  2. Check there are no pipes or obstructions. An easy way to do this is by folding some wire and poking it through your pilot holes at a 90-degree angle and rotating it 360 degrees.
  3. Check the instructions in your downlight box for how big the cut out should be for your fixture. First mark out the size on the ceiling, then, using a hole saw, cut your hole to the correct size.
  4. Once this is done, pull the correct wiring through the hole and wire your LED downlight. In order to fit your downlight, hold the two springs back and push it up into the whole. Once released, these springs will lay flat with the ceiling and hold it in place.
