The quick answer: to light a garage properly in Australia, measure your floor area in square metres, choose a target lux level for how you use the space (roughly 40 to 80 lux for parking and movement, 200 to 300 lux for general work, and 400 to 500 lux over a workbench or detailing zone), then size your lumens with a simple formula. A standard 36 square metre double garage set up for general work needs around 10,000 delivered lumens spread evenly across the ceiling. This guide gives you the exact calculation, a garage-size-to-coverage table, a concrete answer on how many hexagon lights a garage needs, and how to choose a plug and play LED garage lighting system that stays bright for years.
How much light does a garage actually need?
Most Australian garages are under-lit. One or two old fluorescent battens throw hard shadows across the car, leave the corners dark, and take a moment to flicker into life on a cold morning. Good garage lighting is not about finding a brighter globe. It is about choosing the right total light output for your floor area and the tasks you actually do in the space.
Lighting is measured two ways, and knowing the difference is the key to getting garage lighting right. Lumens are the total amount of light a fixture produces. Lux is how much of that light lands on a surface (one lux equals one lumen per square metre). You buy lumens, but what matters on the garage floor and workbench is lux.
Recommended lux levels for a garage
The Australian and New Zealand standard for interior lighting, AS/NZS 1680, sets recommended maintained illuminance levels by task. Use these as practical targets for the different zones of a garage:
- Parking, storage and general movement: around 40 to 80 lux. Enough to park safely, move around the car and find things.
- General work, maintenance and hobby tasks: around 200 to 300 lux. The right level for most home garages and home workshops.
- Workbench, fine assembly, car detailing and inspection: around 400 to 500 lux. Reserve this brighter level for the specific zone where close work happens, not the entire garage.
These figures are guidance drawn from the task levels in AS/NZS 1680, not a fixed legal minimum for a private home garage. If your garage is a registered workplace, check the current standard and any WorkSafe requirements for your state, because the safe level depends on the exact task being performed. For a deeper look at the numbers, see our full guide on how many lumens a garage needs in Australia.
The garage lighting calculation (worked example in metric)
Here is the formula lighting designers use, simplified for a garage:
Lumens needed = (target lux × floor area in m²) ÷ light loss factor
The light loss factor accounts for two real-world losses: not all of the light from a ceiling fixture reaches the floor (some is absorbed by walls, the car and the fitting itself), and every LED slowly dims over its life. For a typical garage with light-coloured or plasterboard walls, a factor of 0.7 is a sensible, conservative allowance. Using it means your garage still hits its target lux years later, not just on the day it is installed.
Worked example: a standard double garage
Take a common 6 m × 6 m double garage used for general work and the occasional detailing session:
- Floor area: 6 × 6 = 36 m²
- Target lux for general work: 200 lux
- Base lumens: 200 × 36 = 7,200 lumens
- Adjusted for real-world losses: 7,200 ÷ 0.7 = about 10,300 delivered lumens
So a 36 m² double garage needs roughly 10,000 to 10,500 lumens spread evenly across the ceiling to sit comfortably at general-work brightness. The word "spread" matters. Ten thousand lumens from a single fitting in the centre still leaves the corners and the sides of the car in shadow. Even coverage is exactly why linked hexagon panels suit garages so well: the output is distributed right across the ceiling rather than dumped in one spot.
Garage size to lighting coverage table
Use this table as a starting point. It assumes a 200 lux general-work target and the 0.7 light loss factor from the worked example above. For a bench or detailing bay, add dedicated task lighting to lift that zone to 400 to 500 lux. For a park-and-store garage, you can drop the target toward 80 to 150 lux and scale the lumens down accordingly.
| Garage type | Floor area | Target lux (general work) | Approx. lumens needed | Suggested HEXA system |
|---|---|---|---|---|
| Single garage (approx. 3 m × 6 m) | ~18 m² | 200 lux | ~5,000 to 5,500 lm | Single Garage Classic |
| Extended single / long garage (approx. 4 m × 6 m) | ~24 m² | 200 lux | ~7,000 lm | Extended Single Garage Classic |
| Standard double garage (approx. 6 m × 6 m) | ~36 m² | 200 lux | ~10,000 to 10,500 lm | Double Garage Classic |
| Large double garage (approx. 6 m × 8 m) | ~48 m² | 200 lux | ~13,500 to 14,000 lm | Large Double Garage Classic |
| Triple garage (approx. 6 m × 10 m) | ~60 m² | 200 lux | ~17,000 lm | Large Triple Garage Classic |
| Large workshop / commercial garage (72 m² and up) | 72 m²+ | 200 lux | 20,500 lm and up | Combine multiple hexagon systems, or add LED floodlights for high roofs |
Because every HEXA hexagon system is modular and links together, you are never locked in. Start with the configuration sized for your footprint, then add panels later if you extend the garage or want to lift the light level over a new bench. Ready to match a kit to your space?

How many hexagon lights do I need for a garage?
The honest, practical answer is that a garage is not lit by chasing a single number of panels. It is lit by delivering the right total lumens, spread evenly across the ceiling, for your floor area and tasks. Work out your lumen target from the calculation above, then choose the HEXA hexagon system configured to deliver it.
As a quick guide based on the table above:
- Single garage (~18 m²): one Single Garage Classic hexagon system, aiming for around 5,000 to 5,500 lumens.
- Standard double garage (~36 m²): one Double Garage Classic system, aiming for around 10,000 to 10,500 lumens.
- Large double or triple garage (48 to 60 m²): a Large Double or Large Triple Garage Classic system, or two linked systems.
Each HEXA kit is a pre-configured layout of linked hexagon bars and connectors sized to its garage footprint, so you are choosing a complete system rather than counting individual pieces. Because the ranges are modular, the exact panel and connector count varies with the configuration you pick. For the precise number of hexagons in each layout and a worked sizing walkthrough, see how many hexagon lights do I need, and for the most common Australian setup, how many hexagon lights for a double garage.
Choosing the right colour temperature for a garage
Colour temperature, measured in Kelvin (K), changes how the garage feels and how well you see detail and true paint colour.
- Warm white (about 3000K): cosy and yellow. Fine for a bar area or a display garage, but it feels dim for real work.
- Neutral white (about 4000K): a balanced all-rounder for a mixed-use garage.
- Cool white (about 5000K to 6500K): crisp, daylight-like, and the best choice for workshops, detailing bays and any garage where you need to judge true colour and see fine detail. This is the range most Australians want for a working garage.
HEXA hexagon systems let you select your colour temperature, so you can match the light to how the garage is used rather than settling for whatever a hardware-store globe happens to be. For a full breakdown, read our guide to the best colour temperature for a garage workshop.
Glare, even coverage and getting the layout right
Brightness is only half the job. Harsh glare from a single fierce light causes eye strain and casts hard shadows exactly where you are working. Two things fix it:
- Spread the light. Several linked panels across the ceiling give flat, shadow-free coverage over the whole floor and both sides of the car. This is the core advantage of a hexagon layout over one central batten.
- Diffuse the source. A diffused LED panel is far more comfortable to work under than a bare, high-output bulb pointing straight down at a glossy bonnet.
Mount fixtures across the ceiling rather than clustering them in the middle, keep the bench and detailing zones directly lit, and avoid leaving any corner in shadow. For a room-by-room plan, see our best garage lighting layout for a home workshop, and if you are weighing how to mount the system, read suspended vs surface mounted garage lighting.
Hexagon LED vs traditional garage lighting
Most garages still run fluorescent tubes, basic LED battens or scattered downlights. They light the space, but they light it unevenly, leaving shadows over the car and dark corners where you keep tripping over things. Modular hexagon LED systems solve the two problems battens cannot: they spread high output evenly across the whole ceiling, and they turn a plain ceiling into a clean architectural feature.
Compared with a run of LED strip, a linked hexagon system is a single engineered luminaire rather than a length of tape, with a diffused finish, honest output and a proper warranty behind it. For the full comparison, see hexagon lights vs LED strip lighting for garages.
Honest talk about lumens
Lumen numbers on cheap imported garage lights are often optimistic, quoted at the LED chip rather than what actually leaves the fitting, and measured brand new before any lumen depreciation. Two lights both labelled "10,000 lumens" can perform very differently on your garage floor. What matters is delivered, maintained lumens over the life of the product, backed by a real warranty. That is why this guide builds in a light loss factor, and why a genuine, long-life system is worth more than a big number printed on a box. When you compare options, weigh the warranty and the rated lifespan alongside the lumen claim.
Australian compliance: what RCM and EESS actually mean
Any mains-powered light sold and used in Australia must meet Australian electrical safety and electromagnetic compatibility rules. Two things prove a supplier is doing this properly:
- RCM certified: the Regulatory Compliance Mark shows a product meets the applicable Australian electrical safety and EMC requirements. It is the mark to look for on any light going into an Australian garage.
- EESS registration: the Electrical Equipment Safety System is the national scheme for in-scope electrical equipment. HEXA Lighting is a registered Responsible Supplier under EESS, registration number E20062. That registration is a supplier-level commitment to Australian electrical safety, not just a printed sticker.
Buying from an EESS-registered, RCM-compliant supplier matters most with imported lighting bought online, where compliance is often unverified. It is a genuine safety and insurance consideration for your garage. Damp, dusty or exposed spaces have their own requirements too, covered in our guide to IP ratings for garage and workshop lighting.
Plug and play installation and warranty
HEXA hexagon garage systems are plug and play. They run from a standard 240V power point using a standard 3-pin plug, so you can light a garage without running a new hardwired circuit, which keeps both the cost and the disruption down. The panels link together with precision adapters to form the layout your garage needs. If your garage already has a power point, you can set the system up yourself; if it has no power at all, a licensed electrician would install a power point first.
Every HEXA hexagon system is backed by a genuine 7-year warranty. The Classic hexagon range is rated for a 70,000-hour lifespan, while the RGB, RGBW and downlight ranges are rated at 50,000 hours. At a few hours of garage use a day, that is many years of reliable light before replacement would even cross your mind.

Garage lighting FAQ
How many lumens do I need to light a garage?
As a rule of thumb, multiply your garage floor area in square metres by 200 lux (a general-work target), then divide by 0.7 to allow for real-world light losses. A 36 m² double garage works out to about 10,000 lumens. Increase the target to 400 to 500 lux over a workbench or detailing zone, or reduce it to 80 to 150 lux for a park-and-store garage.
How many hexagon lights do I need for a garage?
Choose the hexagon system by garage size rather than counting individual panels: a Single Garage Classic suits a small single garage of around 18 m², a Double Garage Classic suits a standard 36 m² double garage, and Large Double or Triple systems suit garages up to 60 m². Each kit is a pre-configured layout of linked hexagons sized to that footprint, so you buy the complete system that delivers the lumens in the table above.
What is the best colour temperature for a garage?
Cool white, around 5000K to 6500K, is best for a working garage or workshop because it is crisp and daylight-like, making detail and true paint colour easy to see. Use warmer 3000K to 4000K light only for a bar area or display-style garage.
Can I install garage lights without an electrician?
HEXA hexagon garage systems are plug and play. They run from a standard 240V power point with a standard 3-pin plug, so if your garage already has a power point you can set them up yourself. If your garage has no power at all, you would need a licensed electrician to install a power point first.
Are LED garage lights better than fluorescent battens?
Yes, for most garages. LED starts instantly at full brightness even in the cold, does not flicker or hum, lasts far longer, uses less power, and does not contain the mercury found in fluorescent tubes. Fluorescent battens are slow to warm and struggle in unheated Australian garages in winter.
How long do HEXA garage lights last?
The Classic hexagon range is rated for 70,000 hours, and the RGB, RGBW and downlight ranges for 50,000 hours. Every HEXA hexagon system also carries a 7-year warranty.
Are HEXA garage lights compliant in Australia?
Yes. HEXA hexagon systems are RCM certified against the applicable Australian electrical safety and EMC requirements, and HEXA is a registered Responsible Supplier under the Electrical Equipment Safety System (EESS registration number E20062).
What size hexagon system suits my garage?
Match the system to your footprint: a Single Garage Classic suits a single garage of around 18 m², a Double Garage Classic suits a standard 36 m² double garage, and Large Double or Triple systems suit garages up to 60 m². Larger workshop and commercial garages can combine multiple systems or add LED floodlights. See the garage size to coverage table above.
