Can you install can lights on vaulted ceiling?

Installing can lights on a vaulted ceiling can add drama and style to a room, but it does require some special considerations. With good planning and the right techniques, it is certainly possible to add recessed lighting to a vaulted ceiling.

What are Can Lights?

Can lights, also known as recessed lights or downlights, are cylindrical light fixtures that are installed into the ceiling. The trim and bulb of the light sit flush with the ceiling, creating a clean, built-in look. Can lights direct light downward, providing task lighting or accent lighting focused on a particular area.

Benefits of Can Lights in a Vaulted Ceiling

There are several benefits to installing can lights in a room with a vaulted ceiling:

  • Creates a focal point – The lights can draw attention to a particular area or architectural feature.
  • Adds drama – Can lights add style and atmosphere to a high, sloped ceiling.
  • Provides task lighting – Focused beams from can lights can illuminate work areas or living spaces that need bright, direct lighting.
  • Versatile – Available with a range of beam spreads and bulb types to customize the lighting effects.
  • Easy to install – Wiring and installing the lights is relatively straightforward.

Challenges of a Vaulted Ceiling Installation

Although installing can lights in a standard flat ceiling is fairly simple, a vaulted ceiling presents some unique challenges:

  • Angled surface – It can be difficult achieving even spacing and getting the lights properly aligned on an angled, irregularly shaped ceiling.
  • Accessibility – Vaulted ceilings are higher, so accessing the installation points may require scaffolding or tall ladders.
  • Wiring – Running wires through framing on a sloped ceiling takes more planning and effort.
  • Heat buildup – Recessed lights in a tight, enclosed vaulted ceiling space need adequate clearance to prevent overheating.

Tips for Installing Can Lights in a Vaulted Ceiling

To successfully install recessed lighting in a vaulted ceiling:

Choose the Right Fixtures

  • IC rated – Use insulation contact (IC) rated can lights that are designed to be in direct contact with insulation.
  • Adjustable – Models with rotating trims or adjustable beams help angle the light on uneven ceilings.
  • Trimless – These fixtures are designed for ceilings with tight spaces and optimal heat dissipation.

Plan the Layout

  • Map it out – Sketch the ceiling with measurements to plan optimal fixture placement and spacing.
  • Account for angles – Adjust the layout to accommodate uneven areas and slopes.
  • Mind the height – Place lights lower on the ceiling since vaults are so high up.
  • Focus on key areas – Illuminate important living and work spaces.

Cut the Holes

  • Use a template – Trace the can light template onto the ceiling to cut uniform holes.
  • Follow codes – Fixtures must be a certain minimum distance from joists, rafters, etc.
  • Make it bigger – Size the holes an 1/8 to 1/4 inch bigger than the can to allow airflow.

Run the Wiring

  • Plan the circuitry – Run wiring to tie all fixtures together on a single circuit.
  • Use 14/2 wire – For lighting, use 14-gauge wire with black, white, and ground wires.
  • Protect wires – Secure wires to avoid tension and leaving insulation exposed on sharp corners.

Install the Lights

  • Attach to framing – Use included braces to secure each can firmly between ceiling joists or rafters.
  • Adjust the angle – Tilt and rotate adjustable fixtures to aim the beam.
  • Insulate properly – Pack insulation around and over IC lights, leaving no gaps.
  • Connect wiring – Connect black (hot), white (neutral), and copper ground wires.

How Many Can Lights in Vaulted Ceiling?

The number of recessed lights needed depends on the size and layout of the vaulted ceiling:

Room Size Recommended Number of Can Lights
5×5 feet 1-2
10×10 feet 2-4
15×15 feet 4-6
20×20 feet 6-8

Space the lights evenly at 2-4 feet apart down the length of the vault. Focus extra lighting over important living and workspace areas.

Conclusion

Installing recessed can lights in a vaulted ceiling requires careful planning and execution. Choosing adjustable IC rated fixtures, mapping a good layout, making clean wire runs, and properly securing the lights are keys to success. With the right techniques and safety precautions, you can add beautiful, functional can lighting to any vaulted ceiling space. The dramatic light and shadows will enhance the aesthetic appeal of your unique ceiling.
