Upgrading garage lighting is one of the most popular home improvement projects for homeowners across Australia and New Zealand. A well-lit garage improves visibility, safety, and the overall look of the space.
One of the most common questions homeowners ask is: How many lumens do I actually need in a garage? Will my hexagon lights be too bright for my garage?
The answer depends on three key factors:
- Garage size (sqm)
- Intended use (parking, DIY work, detailing)
- Lighting layout and ceiling coverage
Many garages still rely on a few fluorescent tubes in the centre of the ceiling. While these fixtures provide basic illumination, they often create shadows around vehicles and work areas.
Advanced lighting systems such as hexagon lights distribute light more evenly across the ceiling, improving overall visibility and reducing shadows around vehicles.
In this guide, we’ll explain:
- How to calculate the correct lumen level for your garage
- Recommended brightness for different garage sizes
- Why lighting coverage matters as much as brightness
- Which hexagon lighting kits work best for typical Australian and New Zealand garages
What Are Lumens and Why Do They Matter?
Lumens measure the total amount of visible light emitted by a light source. In simple terms: more lumens equals brighter light.
However, brightness alone does not determine lighting quality. Good lighting design also requires uniform distribution to reduce shadows and improve visibility across the whole garage.
Garage Lighting Calculator (sqm Method)
Lighting designers often estimate required brightness using lux, which represents the amount of light reaching each square metre.
Formula
Required Lumens = Garage Area (sqm) × Target Lux
Typical brightness levels for garages:
| Garage Use | Recommended Brightness |
|---|---|
| Parking / Storage | 500 to 700 lux |
| DIY / Workshop | 700 to 1000 lux |
| Showroom / Display Garage | 800 to 1200 lux |
| Car Detailing | 1000 to 1500 lux |
Example Calculation
Example: 36 sqm double garage
- Parking: 36 × 500 to 700 lux = 18,000 to 25,200 lumens
- DIY: 36 × 700 to 1000 lux = 25,200 to 36,000 lumens
- Showroom / Display: 36 × 800 to 1200 lux = 28,800 to 43,200 lumens
- Detailing: 36 × 1000 to 1500 lux = 36,000 to 54,000 lumens
Important: lumen output alone does not guarantee good lighting performance. Lighting layout and ceiling coverage also play a major role.
Why Coverage Matters for Garage Lighting
Many people focus only on lumen output, but in garages, even lighting distribution is just as important. If lights cover only a small portion of the ceiling, you may still get shadows around vehicles, darker areas near walls, and uneven brightness across the garage.
Recommended ceiling coverage targets:
| Usage | Ceiling Coverage Target |
|---|---|
| Daily parking | 40% to 60% |
| DIY workspace | 60% to 80% |
| Detailing / showroom | 80% to 100% |
This is one reason hexagon lighting systems are popular. Their grid layout spreads light across the ceiling, improving uniformity and reducing shadows.

Recommended Kits by Garage Size (sqm)
Below are realistic recommendations based on typical garage sizes in Australia and New Zealand. These suggestions consider both lumen needs and ceiling coverage for more even lighting.
Single Garage (about 18 sqm)
Target lumen ranges
- Daily use: 9,000 to 12,600 lumens
- DIY / workshop: 12,600 to 18,000 lumens
- Showroom / display garage: 15,000 to 24,000 lumens
- Car detailing: 18,000 to 27,000 lumens
Recommended kits
- 3 Grid (≈10,500 lumens): suitable for basic daily parking and storage.
- 5 Grid (≈15,500 lumens): good brightness for daily use and DIY garages.
- 8 Long Grid (≈24,400 lumens): wider ceiling coverage and ideal for showroom-style garages or entry-level car detailing.
Most single garages install one kit.
Double Garage (about 36 sqm)
Target lumen ranges
- Daily use: 18,000 to 25,200 lumens
- DIY / workshop: 25,200 to 36,000 lumens
- Showroom / display garage: 28,800 to 43,200 lumens
- Car detailing: 36,000 to 54,000 lumens
Recommended kits
- Two 3 Grid kits (≈21,000 lumens total): suitable for basic daily parking.
- Two 5 Grid kits (≈31,000 lumens total): better brightness and coverage for daily use and DIY tasks.

One Large Kit or Multiple Kits?
When lighting larger garages, you may choose between one large kit or multiple medium kits. Each option has its own advantages depending on your ceiling layout and how the space is used.
Large kit advantages
- Uniform lighting coverage across the entire ceiling
- Minimal dark spots and fewer shadows around vehicles
- Strong visual impact with a clean, continuous lighting layout
- Creates a premium showroom-style appearance
Multiple kits advantages
- More flexible installation for different garage layouts
- Easy to install around ceiling obstacles such as garage door openers
- Kits can be positioned on both sides of the opener for balanced lighting
- Allows lighting to be placed directly above work areas such as workbenches
- Zone control is possible, making it easier to control lighting in different areas
For many double garages, two medium kits provide the most even light distribution. For larger garages, one large kit can create a cleaner ceiling layout and a strong full-ceiling look.
Best Colour Temperature for Garage Lighting
Colour temperature affects how clearly surfaces and details appear under lighting. Choosing the right colour temperature can improve visibility for everyday garage tasks, workshops, and precision work such as car detailing.
| Colour Temperature | Appearance | Best Use |
|---|---|---|
| 4000K | Neutral warm white | A slightly warmer and more comfortable light. Suitable for relaxed garages, hobby spaces, or areas where strong task lighting is not required. |
| 5000K | Natural daylight white | Balanced brightness for everyday garage use, including DIY projects, general workshops, and household tasks. |
| 6500K | Cool daylight white | High-clarity lighting ideal for precision work such as car detailing, barber shops, mechanical work, and other environments where fine surface details need to be visible. |
For most residential garages, 5000K is the most popular choice, as it provides bright, natural lighting without appearing too cold.
Many car detailing professionals prefer 6500K lighting, because the cooler colour temperature helps highlight swirl marks, scratches, and paint imperfections more clearly.
High colour rendering is also important for task lighting. Lighting with CRI >85 provides more accurate colour reproduction, helping reveal surface details more clearly during work such as polishing, mechanical repairs, or detailing.
FAQ
How many lumens do I need for a double garage lighting setup?
Most double garages require 25,000 to 35,000 lumens for comfortable lighting, depending on ceiling height, layout, and how you use the space.
Will hexagon lights be too bright?
Not usually. Evenly distributed lighting often feels more comfortable than a few concentrated bright fixtures. If you're unsure, choose a layout that improves coverage and consider a softer colour temperature such as 5000K.
Is one large lighting kit better than two smaller ones?
Two kits often provide more even coverage, which reduces shadows around vehicles. One large kit can create a cleaner ceiling layout and a stronger full-ceiling look.
Conclusion
Good garage lighting is not only about brightness. The best lighting combines:
• Sufficient lumen output
• The right colour temperature for the task
• Even ceiling coverage to reduce shadows
