Key Takeaways
- Divide your ceiling height by two to estimate downlight spacing.
- Adjust spacing based on beam angle and room purpose.
- Avoid overcrowding lights or creating dark spots.
- Always use a licensed electrician for installation and design.
Installing downlights is one of the most effective ways to modernise your home and improve lighting comfort. But to get that perfect, even glow across your rooms, spacing matters just as much as style. Incorrect downlight spacing can make a space feel patchy, dim, or overly bright, wasting energy and affecting the room’s overall look. In this guide, we’ll explain how to choose the right downlight spacing for each room, common mistakes to avoid, and when to call a professional for help.
Why Downlight Spacing Matters
Proper spacing ensures your lighting looks balanced, efficient, and functional. When done correctly, downlights can:
- Provide consistent illumination across the entire room.
- Reduce shadows and glare.
- Highlight specific areas or design features.
- Improve the overall aesthetic appeal of your home.
If your downlights are placed too close together, the room may appear overly bright or uneven. Too far apart, and you’ll end up with dark patches or insufficient light in key areas.

General Rule for Downlight Spacing
A simple rule of thumb is to divide the ceiling height by two.
For example:
- In a room with a 2.4-metre ceiling, lights should be spaced about 1.2 metres apart.
- In a room with a 3-metre ceiling, spacing can increase to around 1.5 metres.
This formula provides balanced lighting coverage without overlap or dim spots. However, the right spacing also depends on beam angle, room size, and purpose.
Consider the Beam Angle
The beam angle is the spread of light emitted from each downlight, measured in degrees.
- Narrow beam (≤ 40°): Ideal for highlighting artwork, benchtops, or specific features.
- Medium beam (around 60°): Best for general-purpose lighting in most rooms.
- Wide beam (≥ 90°): Suitable for open-plan spaces or low ceilings where broader coverage is needed.
Choosing the correct beam angle will help determine how far apart your downlights should be to achieve even illumination.
Adjusting Spacing by Room Type
Different rooms require different lighting intensities and layouts. Here’s how to tailor downlight spacing for each area of your home:
1. Living Rooms
For living areas, aim for an even, comfortable glow rather than intense brightness. Space your downlights approximately 1.2 to 1.5 metres apart, depending on ceiling height and beam width. Consider adding accent lights above seating areas or display shelves to create a warm, inviting atmosphere.
2. Kitchens
Kitchens need functional task lighting, especially over benches, sinks, and cooktops. Place downlights directly above work areas and maintain about 1 metre spacing between lights for consistent coverage. Avoid placing lights directly above cabinet doors, as they can cast unwanted shadows.
3. Bathrooms
Bathroom lighting should balance brightness and safety. For general lighting, keep downlights spaced 1 to 1.2 metres apart, using IP-rated fittings suitable for wet zones. Avoid over-lighting by pairing ceiling downlights with wall-mounted fixtures or vanity lighting.
4. Hallways and Corridors
For narrow spaces, downlights can be spaced slightly closer together around 1 to 1.2 metres apart to eliminate shadows and provide clear visibility.
5. Bedrooms
Bedrooms benefit from softer, ambient lighting. Space downlights 1.5 to 2 metres apart, or use dimmable fittings to adjust brightness as needed.
Avoiding Common Downlight Mistakes
Even the best lights won’t perform well if installed incorrectly. Here are a few common mistakes to avoid:
- Overcrowding lights: Too many downlights increase glare and waste energy.
- Uneven placement: Irregular spacing can create dark patches or hotspots.
- Ignoring furniture layout: Always plan lighting around where beds, sofas, and benches are located.
- Using the wrong fittings: Low-quality or non-compliant lights may not distribute light evenly and could pose safety risks.
