How do I convert from 6 inch to 3 inch recessed lights?

Recessed lighting has been the lighting of choice for home builders and homeowners alike since the 1980s. These fixtures give a ceiling a clean and uncluttered look while at the same time providing ample lighting and avoiding dark spots that occur with conventional lighting schemes. Depending on taste, some people prefer the 3-inch recessed lighting to the 6-inch recessed lighting that is more common. Changing from the 6-inch recessed lights to the 3-inch is very simple and can be performed in a few hours.

Skill level:

Things you need

  • Step ladder
  • 3-inch light bulbs
  • Clean rag
  • 6-inch reducer ring

  1. 1

    Make sure the lights are off. Set up your step ladder underneath the 6-inch recessed light and set a 3-inch bulb and the 6-inch reducer trim on the top of the ladder.

  2. 2

    Climb up the ladder and pick up your clean rag. Unscrew the 6-inch trim piece from the recessed light by turning it counterclockwise. Set it down and remove the 6-inch bulb.

  3. 3

    Install the 3-inch bulb in the socket. Screw in the 6-inch reducer trim. This trim is made for reducing the opening in the can light from 6 inches to 3 inches. Only the 3 inch bulb is now visible. Repeat this for the remainder of the recessed lights that you want to reduce to 3 inches.

Tips and warnings

  • Reducer kits come in many different colours and styles so make sure you choose something that goes with the rest of your decor.
  • Use caution when working with electricity. Do not stick your fingers in or on the metal socket piece to avoid electric shock.
