The short answer: what is the best lighting for an epoxy garage floor?
The best lighting for an epoxy garage floor is a continuous, diffused LED layout, such as a hexagon grid or evenly spaced linear fittings, in 5000K to 6500K with a high colour rendering index (CRI). A gloss epoxy floor behaves like a mirror. Continuous, diffused light reflects as one clean, deliberate pattern, while scattered point sources show up as a field of bright dots and hotspots. Get the shape, spread and colour of the light right and the floor looks like a showroom instead of a reflection of every fitting on the ceiling.
Why an epoxy floor changes your lighting plan
A bare concrete slab soaks up light and hides how it is spread. Epoxy does the opposite, so the lights you choose become part of the look of the floor.
Gloss, satin and matte finishes
- High gloss epoxy or polyaspartic: acts close to a mirror. You see a sharp, second image of every fitting on the floor.
- Satin: softens reflections into glowing patches. Point sources still show as bright blobs.
- Matte or textured flake: diffuses reflections. Brightness and colour matter more than fitting shape.
Hotspots, doubled images and crouching glare
On a gloss floor each fitting appears twice: once on the ceiling and once below you. Small, intense sources create hard hotspots and uneven pools between them. The worst glare happens when you crouch beside a car to check paint or work on wheels, because your eyes are close to the floor and catch the reflected light at a low angle. A lighter coloured floor, such as light grey flake, also bounces more light around the room than charcoal or black, so the same fittings will feel brighter.
Hexagon grids vs battens, panels, high bays and downlights on gloss epoxy
Here is how the common garage ceiling options behave on a reflective floor. Cost is relative for a typical double garage and depends on size and specification.
| Fitting type | Reflection on gloss | Glare | Uniformity | Shadows under cars | Look | Best ceiling height | Relative cost |
|---|---|---|---|---|---|---|---|
| Hexagon grid | One clean, continuous pattern | Low, diffused tubes | Very high | Low, light comes from many directions | Showroom, feature ceiling | 2.4 m to 3 m | $$ to $$$ |
| LED battens in rows | Neat parallel lines if aligned | Low to medium | Good with close spacing | Medium | Functional | 2.4 m to 3.5 m | $ to $$ |
| Flat panels | Bright squares on the floor | Low | Good | Medium | Office style | 2.4 m to 3 m | $$ |
| UFO high bays | Few intense circles | High at low heights | Patchy below about 4 m | High between fittings | Industrial | 4 m and above | $$ |
| Downlights | Grid of hard dots | Medium to high | Poor to fair | High | Residential | 2.4 m to 2.7 m | $ to $$ |
For most Australian garages with 2.4 m to 2.7 m ceilings, a hexagon LED lighting grid gives the most even light and the best looking reflection. High bays are designed for tall sheds and warehouses, and they tend to create glare and hard pools at standard garage heights.
How much light does an epoxy garage need?
Plan in lux (light landing on a surface) and convert to lumens (light output of the fittings). These practical targets work well in residential garages:
- Parking and storage: about 150 to 200 lux
- General workshop and hobby work: about 300 to 500 lux
- Detailing, paint correction and fine work: about 750 to 1,000 lux or more at the panel
A simple estimate is: lumens needed = target lux x floor area / 0.65. The 0.65 allows for light lost to walls and fittings in a room with a white ceiling. A light, gloss floor reflects more light back up than bare concrete, so if you plan to the upper end of the range you can usually stay near the lower end of the lumen estimate rather than overlighting. Dimming is the easiest safety net. HEXA's dimmable hex lighting Classic models dim straight from a standard wall switch with no separate dimmer required, so you can run full output for detailing and drop it back for parking.
Layouts for single, double and triple Australian garages
| Garage | Approx. area | Lumens for 300 lux | Lumens for 750 lux | Layout suggestion |
|---|---|---|---|---|
| Single (3 m x 6 m) | 18 m2 | about 8,300 lm | about 20,800 lm | One hexagon grid centred along the bay, or two rows of linear fittings |
| Double (6 m x 6 m) | 36 m2 | about 16,600 lm | about 41,500 lm | A grid spanning both bays, or one grid over each bay |
| Triple (9 m x 6 m) | 54 m2 | about 24,900 lm | about 62,300 lm | Grids over each bay with linear fittings over benches |
Adjusting for ceiling height
At 2.4 m, fittings sit close to the car roof, so spread the light wider and keep the grid larger rather than brighter. At 2.7 m, standard surface mounted grids work well and the reflection looks more balanced. Above 3 m, add output or consider a suspended installation to bring the light closer to the work while keeping the clean pattern. Our garage lighting range includes kits sized for single, double and larger bays.
Running costs in AUD
LED running cost is simple to work out: watts / 1,000 x hours x your electricity rate. As a worked example, a 200 W layout used 3 hours a day at 35c per kWh costs about 21c a day, or roughly $77 a year. Check the wattage on the product page and your own tariff for an exact figure.
Colour temperature and CRI on epoxy and paint
4000K vs 5000K to 6500K
4000K is a neutral white that suits a garage doubling as a living or rumpus space. 5000K reads as clean daylight and is the all round choice for workshops. 6000K to 6500K is crisp and cool, popular with detailers because it makes metallic paint, chrome and silver or grey flake look sharp. Warm white under 3500K tends to make light grey flake look yellow and hides paint defects.
Why CRI matters
CRI measures how accurately a light shows colour, out of 100. Low CRI light flattens colour, so flake blends look muddy and paint swirls, holograms and touch up mismatches are harder to see. Aim for CRI 80 as a minimum for general garage use and look for higher CRI if you detail or correct paint.
Controlling glare on a gloss floor
- Use diffused fittings. Opal diffusers spread the light so the reflection is soft and continuous rather than a pinpoint.
- Light the space between cars, not just above them. Centre grids slightly towards the sides of each bay so light reaches doors, wheels and lower panels.
- Avoid fittings directly above where you stand. If you always work at a bench or the driver's door, offset the brightest fittings so their reflection is not in your natural line of sight.
- Keep light near the walls. A row of linear lighting over benches and cabinetry lights vertical surfaces and stops the floor reflection being the only bright thing in the room.
- Paint the ceiling white. It reduces contrast between fittings and ceiling, which cuts glare in the floor reflection.
Install sequencing, ceilings and Australian compliance
Fit lights before the coating
Where possible, run cabling and mount the lights before the floor is coated. Ladders, scaffolds and dropped tools are the main cause of scratches and dents in fresh epoxy. If the floor is already done, stand ladder feet on offcuts of carpet or rubber matting and respect the coater's full cure time before heavy foot traffic or ladders.
Ceiling and mounting types
Plasterboard ceilings suit surface mounting with appropriate fixings, ideally into battens or joists. Exposed trusses and steel sheds often suit suspended mounting from purlins. In Colorbond sheds, check the purlin spacing before planning the grid so it can be fixed securely.
RCM, AS/NZS 60598 and electricians
Lighting sold in Australia should carry RCM marking and be designed to AS/NZS 60598, the luminaire safety standard. Plug and play kits connect to a standard power point. Any hardwired installation, including connection to a wall switch or a new circuit, must be done by a licensed electrician. Our technical guides cover compliance and mounting in more depth.
Frequently asked questions
Do hexagon lights look good on an epoxy garage floor?
Yes. A hexagon grid reflects in gloss epoxy as one continuous, even pattern, which is why it is a popular choice for showroom style garages. Point sources such as downlights reflect as scattered dots instead.
What colour temperature is best for an epoxy garage?
5000K to 6500K suits most epoxy garages. 5000K is a balanced daylight white for workshops, while 6000K to 6500K makes metallic paint and grey or silver flake look crisp. Choose 4000K if the garage doubles as a living space.
How many lumens does a double garage with an epoxy floor need?
About 16,000 lumens for general use at 300 lux in a 36 m2 double garage, and about 40,000 lumens for detailing at 750 lux. A light coloured gloss floor reflects extra light, so dimmable fittings help avoid overlighting.
Should I install garage lights before or after epoxy flooring?
Before, where possible. Fitting lights first keeps ladders and tools off the new coating. If the floor is already coated, wait for the full cure time and protect it with matting under ladder feet.
