If you are fitting out a garage, shed or workshop, the IP rating printed on a light is one of the most important numbers on the box, and one of the most misunderstood. This guide explains exactly what IP ratings mean for fixed ceiling lighting in an Australian garage or workshop, which rating suits each type of space, and how IP sits alongside the AS/NZS standards your fitting has to meet. It is written for real garages and sheds, not caravans, 4WDs or truck spotlights.
Quick answer for a typical Australian garage
For a normal enclosed home garage or lock up shed used for parking, storage and light DIY, aim for a fixed LED fitting rated at least IP44, and step up to IP54 or IP65 if there is noticeable dust, timber or metal dust, or the space ever gets damp. In most Australian garages the bigger enemy is dust, not water, so the first IP digit (solids) usually matters more than the second (water). Anything you hard wire into the ceiling still needs to be an AS/NZS 60598 compliant luminaire carrying a valid RCM mark, regardless of its IP number.
What an IP rating actually means
IP stands for Ingress Protection. It is an international code, defined under the IEC 60529 system, that tells you how well a fitting is sealed against solid objects and water. It is written as the letters IP followed by two digits, for example IP65.
- First digit (solids): 0 to 6. This covers protection against fingers, tools, dust and other particles. 0 means no protection, 5 means dust protected (a little fine dust may enter but not enough to interfere), and 6 means fully dust tight.
- Second digit (liquids): 0 to 8. This covers water, from 0 (no protection) through 4 (splashing from any direction), 5 and 6 (jets and powerful jets), up to 7 and 8 (temporary or continuous immersion).
So an IP65 fitting is fully dust tight and protected against water jets from any direction, which is a sensible upper level for most hard working garages. Higher is not automatically better, as we explain below.
The X notation and IP69K explained
Sometimes you will see an X in place of a digit, such as IP4X or IPX4. The X simply means that digit was not rated or not tested, not that it scored zero. IP4X tells you the solids protection (protected against objects above 1mm) but says nothing about water. IPX4 tells you the water protection (splash resistant) but says nothing about dust. For a dusty workshop an IPX4 claim is close to useless, because it is silent on the very thing that matters most to you.
You may also see IP69K, which is a separate high pressure, high temperature wash down test used in industrial and food settings. It is its own standard and does not automatically mean a fitting also passes IP67 or IP68 immersion. Treat IP69K as a specialist rating, not a trophy digit for a home garage.
Garage and workshop IP decision table
Use this as a starting point, then step up a level if your space is dustier, damper or closer to the coast than average.
| Space or zone | Main risk | Recommended minimum IP |
|---|---|---|
| Dry enclosed lock up garage | Light dust | IP20 acceptable, IP44 preferred |
| Everyday working garage with dust | Dust and debris | IP44 to IP54 |
| Timber or metalworking workshop (fine dust) | Fine airborne dust | IP54 to IP65 |
| Detailing or wash bay with direct water | Water jets and spray | IP65 |
| Carport or semi open bay | Wind driven dust and rain | IP54 to IP65 |
| Under eave or exterior soffit | Splash and humidity | IP54 minimum, IP65 near coast |
| Damp or coastal areas | Moisture and salt | IP65 and suitable materials |
You can browse fittings built for these spaces in the Garage Lighting collection and the Workshop Lighting collection.
Why dust beats water in most Australian garages
In the majority of Australian garages and sheds, water rarely touches the ceiling. Dust, on the other hand, is constant: brake dust, tyre grit, timber and MDF dust, grinding and sanding particles, and general airborne grime. Fine dust settles on heat sinks and works its way into seams, which is why the first digit often deserves more attention than the second in a workshop. A fitting that is only IPX4 splash rated but has a weak solids rating can clog and run hot over time. For a serious timber or metal workshop, prioritise a strong first digit (5 or 6) so the fitting stays clean inside and sheds dust rather than trapping it.
How IP ratings fit Australian standards
An IP rating is a performance measure, not a licence to sell. In Australia, a fixed mains light is separately governed by safety and compliance rules:
- AS/NZS 60598 is the luminaire safety standard that the fitting itself must meet. A high IP number does not replace this.
- AS/NZS 3000 (the Wiring Rules) sets out how fixed wiring is installed and defines wet area zones where minimum IP levels apply, for example around wash bays and wet zones.
- The RCM mark (Regulatory Compliance Mark) shows the supplier has taken responsibility for electrical safety and electromagnetic compliance. Look for it.
- SAA approval and the EESS national database cover approval of electrical equipment. In line electrical products should be traceable through the Electrical Equipment Safety System.
For a deeper look at luminaire safety specifically, see our technical blog, which covers AS/NZS 60598 and garage compliance in detail.
Heat, roof cavities and sealed fittings
Sealing a light tightly helps keep dust out, but it also keeps heat in. Australian roof cavities and garage ceilings can get very hot in summer, and LEDs lose life if they run hot. A high IP rating is only useful when it is paired with proper thermal design, so the fitting is engineered to shed heat even while sealed, and remains AS/NZS 60598 compliant. Do not assume a higher IP number means a better or cooler running light. Good fittings balance sealing with effective heat management.
How to read a spec sheet and spot fake IP claims
A genuine IP rating appears on the product label, the box and the spec sheet, usually near the voltage, wattage and the AS/NZS compliance details. When you are comparing fittings, watch for these warning signs common on cheap imports:
- An IP rating quoted in the marketing copy but missing from the actual spec sheet or label.
- Vague wording like "waterproof" or "dustproof" with no IP number at all.
- An IP rating but no mention of AS/NZS 60598, no RCM mark and no traceable approval.
- Impossible or inconsistent claims, such as a flimsy open fitting labelled IP68.
If the IP figure is not backed by a clear compliance statement, treat the whole listing with caution.
IP is not IK, and IP is not a quality measure
Two common misconceptions trip buyers up. First, IP does not cover impact resistance. That is the separate IK rating, which measures how well a fitting resists knocks (useful if a reversing car, a ladder or a flying offcut might strike it). Second, an IP rating says nothing about brightness, colour quality or how long the light lasts. It only describes sealing against solids and water. A cheap, poorly built light can still carry a high IP number, so judge the whole package, not just the two digits.
Can you self install, or do you need a licensed electrician
In Australia, hard wiring a fixed light into mains power is electrical work that must be carried out by a licensed electrician. That is a legal requirement, not a preference. Plug and play fittings that connect to an existing power point without any mains wiring can be set up yourself, which is one reason plug and play hexagon systems are popular for garages. If a fitting has to be wired into the circuit or switched from a standard wall switch via fixed wiring, book a licensed electrician. You can pair professionally installed or plug and play options from the Hexagon LED Lighting collection to suit either path.
Maintenance and longevity
The right IP rating directly extends the life of a fitting. Dust that cannot get in cannot coat the internals and drive up running temperatures, and seals that keep moisture out prevent corrosion. Over time, gaskets and seals do age, harden and shrink, so even a well rated fitting benefits from an occasional check and a gentle wipe down of the exterior. Choosing an appropriate IP level for your actual conditions, rather than the highest number you can find, keeps fittings cleaner, cooler and working for longer.
Frequently asked questions
What IP rating do I need for a garage in Australia?
For a typical enclosed home garage, aim for at least IP44, and step up to IP54 or IP65 if the space is dusty, damp or used as a working garage. IP44 handles everyday splashes and light dust, while IP65 is fully dust tight and jet resistant for harder working spaces.
Is IP20 okay in a dry garage?
IP20 can be acceptable in a clean, dry, fully enclosed lock up garage used mainly for parking and storage, since it offers no water protection and only basic solids protection. In any garage with real dust, humidity or DIY work, IP44 or higher is the safer choice.
Do I need IP65 in a workshop?
For a timber or metalworking workshop with fine airborne dust, IP54 to IP65 is recommended so the fitting stays sealed against dust. In a workshop, a strong first digit (dust protection) usually matters more than the water digit, and IP65 gives you full dust tightness.
What IP rating is best for a wash bay or detailing area?
For a detailing or wash bay where direct water and spray are used, choose IP65 so the fitting is protected against water jets from any direction. Also check that the installation follows AS/NZS 3000 wet area zone requirements, which a licensed electrician can confirm.
Is a higher IP rating always worth paying for?
No. A higher IP rating is only worth paying for if your space genuinely needs it, because over sealing can trap heat and the number says nothing about brightness, build quality or lifespan. Match the IP rating to your real conditions and make sure the fitting is AS/NZS 60598 compliant with a valid RCM mark.
