What Is Can Light Placement?

Can light placement determines:

• Number of recessed lights needed
• Distance between lights
• Distance from walls
• Balanced light distribution

Correct placement ensures uniform brightness across the room.

Required Inputs

1. Room length
2. Room width
3. Ceiling height
4. Desired spacing factor (optional guideline based on ceiling height)

---

Placement Formula

General spacing rule:

Spacing = Ceiling Height ÷ 2

Number of Lights (Length Direction) = Room Length ÷ Spacing
Number of Lights (Width Direction) = Room Width ÷ Spacing

Total Lights = Length Lights × Width Lights

This creates evenly spaced lighting.
