How To Measure Recessed Lighting Size? A Detail Guide

How To Measure Recessed Lighting Size

From a plain and simple space to an extraordinary one, recessed lighting does magic. Attention to detail is the secret behind slick installations that look professional among other things. To make sure they fit perfectly, we’ll delve into some critical steps for measuring recessed lighting.

Precisely measured can lights will blend seamlessly into the ceiling giving it a modern and good look. Incorrect measurements lead to ill-fitting lights that protrude from the ceiling unsightly.

Key Measurements for Recessed Lighting

Before setting up can lights you need two dimensions namely: its diameter and depth (height).

1. Measuring the Diameter

Measuring the diameter of a recessed light is often misunderstood by many people. Many people make mistakes by measuring from edge to edge of fitting. However, this is wrong. To measure diameter correctly remove either trim or LED module from your recessed light fitting and measure across the inside opening of the housing at its widest point.

  • Remove Trim or LED Module: This will give you access to housing.
  • Measure Across Interior of Housing: Measure at the widest point inside the housing so that light will fit snugly into the ceiling opening.

2. The Depth of Unite

The depth also matters equally as much as other factors mentioned above. At the backside LED downlights have a cylinder called a can which contains a bulb for light fitting wiring and sometimes a transformer too. When taking depth measurements check if there’s enough space behind your ceiling for such units. This measurement is crucial since it ensures that your downlight fits snugly into your ceiling without any obstructions.

  • Inspect Space Behind Ceiling: Make sure there’s enough room for the can.
  • Measure from Ceiling Surface to Back of Can: This helps ensure the fixture will fit without hitting any obstacles.
