What IP rating does an outdoor LED floodlight need?
For most Australian homes, sheds and yards, an outdoor LED floodlight should be rated at least IP65. Choose IP66 where the fitting faces tropical downpours, wind driven rain, coastal weather or regular hosing. A sheltered position under eaves can get by with IP44, but IP65 costs little more and gives a far bigger safety margin.
The rest of this guide explains outdoor LED floodlight IP ratings in plain English, then covers the part most guides skip: the weatherproofing details that decide whether a floodlight actually stays dry.
How to read an IP code
IP stands for Ingress Protection. The code is defined in IEC 60529, published in Australia as AS 60529, and it always has two digits.
| Part of the code | What it covers | Range |
|---|---|---|
| IP | Ingress Protection | Fixed letters |
| First digit | Solid objects and dust | 0 to 6, where 5 is dust protected and 6 is dust tight |
| Second digit | Water | 0 to 9, covering drips, splashes, jets, immersion and high pressure hot water |
| X | That digit was not tested or not declared | For example IPX5 |
So an IP65 floodlight is dust tight (6) and protected against water jets (5). An X does not mean zero protection. It means no claim is made for that digit.
IP44 to IP68 compared: what each test involves
| Rating | Dust | The water test | What it means for a floodlight |
|---|---|---|---|
| IP44 | Blocks objects of 1 mm or larger, not dust | Water splashed from all directions | Sheltered spots only, such as under eaves |
| IP54 | Dust protected, some dust may enter without causing harm | Water splashed from all directions | Covered areas with dust, light rain exposure |
| IP65 | Dust tight | Water jet from a 6.3 mm nozzle at 12.5 litres per minute, from about 3 metres | Open weather and normal rain, the practical minimum outdoors |
| IP66 | Dust tight | Powerful jet from a 12.5 mm nozzle at 100 litres per minute, from about 3 metres | Driving rain, storms, coastal and wash down areas |
| IP67 | Dust tight | Temporary immersion, up to 1 metre deep for 30 minutes | Fittings that may sit in pooled water |
| IP68 | Dust tight | Continuous immersion at a depth and duration set by the manufacturer | Submerged fittings, not typical floodlights |
Notice that the IP66 test uses eight times the water flow of the IP65 test. That is the real difference between the two most common floodlight ratings.
Why a higher IP rating is not always better
The water digits are not one continuous ladder. Digits up to 6 are spray and jet tests. Digits 7 and 8 are immersion tests. Under the standard, a fitting marked only IP67 or IP68 is not assumed to have passed the jet tests. A seal that holds under still water can still leak when hit by a hard, directional jet.
If a floodlight needs both, look for a dual rating such as IP66/IP67, which shows it passed each test separately.
IP65 vs IP66 vs IP67 for floodlights
- IP65: the right choice for most walls, sheds, driveways and yards in temperate areas.
- IP66: worth the extra cost for fully exposed poles and gables, northern wet seasons, coastal sites and anywhere the fitting gets hosed.
- IP67: only useful where water can pool around the fitting, such as ground level or in ground positions. A wall or pole mounted floodlight is hit by rain, not submerged, so the jet rating matters more.
Which IP rating for each Australian location?
| Location | Suggested rating | Also consider |
|---|---|---|
| Under eaves or alfresco | IP44 minimum, IP65 preferred | Wind blown rain still reaches covered areas |
| Fully exposed wall or pole | IP65, or IP66 in storm prone areas | Cable entry facing down |
| Shed and garage exterior | IP65 | Dust tight first digit for rural blocks |
| Driveway and security lighting | IP65 | Impact rating if mounted low |
| Sports court or yard | IP65 or IP66 | Impact rating for ball strikes |
| Coastal property | IP66 | Corrosion resistant housing and stainless fixings |
| Pool surrounds | Set by the AS/NZS 3000 pool zones | Your electrician must confirm the zone and fitting |
| Wash down and workshop areas | IP66 | Never aim a pressure washer at seals |
Climate changes the answer. Northern Australia brings intense downpours and wind driven rain. The coast adds salt spray. Rural and outback sites add fine dust, so a first digit of 6 matters. Harsh UV and summer heat age seals and plastics everywhere, and frosty southern nights drive condensation.

Weatherproofing beyond the IP rating
An IP rating describes the fitting as tested in a laboratory. It says nothing about how the cable enters or how the light was mounted, and that is where most real failures start.
- Cable glands: the gland must match the cable diameter and be tightened correctly. An oversized or loose gland is an open door for water.
- Connectors and junction boxes: any join outdoors needs its own suitable IP rating. A sealed floodlight wired into an unsealed box is not a weatherproof installation.
- Drip loops: let the cable dip below the entry point so water runs off the low point instead of tracking into the fitting.
- Mounting orientation: follow the manufacturer's instructions, keep cable entries facing down or sideways, and avoid positions where water pools on the lens or housing.
- Driver placement: if the driver is separate, it needs the same protection as the light or a sheltered location.
Why IP rated floodlights still fail
Condensation is the most common complaint. A floodlight heats up when on and cools quickly when switched off or hit by cold rain. The cooling air inside contracts and pulls moist air past any weak seal or along the cable. Better fittings use a pressure equalisation vent, a membrane that lets air through but blocks liquid water.
Other causes are gaskets pinched during assembly or hardened with age, UV degraded seals and lenses, damaged cable sheaths, and housings opened and not resealed properly.
Corrosion and impact are separate from IP
An IP code does not measure corrosion resistance. Near the coast, look for a die cast aluminium housing with a quality powder coat, stainless steel fixings and a tempered glass lens, which resists UV yellowing better than polycarbonate. Polycarbonate handles impact better.
Impact resistance has its own scale, the IK rating under IEC 62262, running from IK00 to IK10. IK08 withstands a 5 joule impact and IK10 withstands 20 joules. It matters for low mounted fittings, driveways, sports areas and public spaces.
Australian standards and who can install a floodlight
- AS 60529 defines the IP code and its tests.
- AS/NZS 3000, the Wiring Rules, requires electrical equipment to suit the conditions where it is installed, and sets specific rules for wet areas and pool zones.
- The RCM (Regulatory Compliance Mark) shows a supplier has declared the product meets applicable Australian electrical safety and EMC requirements.
- A licensed electrician must install any hardwired floodlight in Australia. Fixed wiring is not legal DIY work.
You can read more about compliance in the HEXA technical guides, or see why Australians choose HEXA.
Maintenance and buying checklist
Once a year
- With power isolated, check the lens and seals for cracks, yellowing or gaps.
- Look for moisture or water marks behind the lens.
- Check the gland is tight and the cable sheath is intact.
- Rinse salt and dust off gently. In coastal areas do this more often.
- Check fixings and brackets for rust and looseness.
Before you buy
- IP65 minimum, IP66 for harsh exposure, with the rating clearly stated.
- RCM marking and an Australian supplier.
- Housing, lens and fixings suited to your location.
- An IK rating if the light can be struck.
- A clear warranty and installation instructions.
Frequently asked questions
Is IP65 enough for an outdoor floodlight?
Yes, IP65 is enough for most outdoor floodlights in Australia. It means the fitting is dust tight and protected against water jets, which covers normal rain on an exposed wall. Step up to IP66 for tropical storms, coastal sites or areas that are hosed down.
Is IP67 better than IP66 for a floodlight?
Not necessarily. IP67 is an immersion test and IP66 is a powerful water jet test, and passing one does not prove the other. For a wall or pole mounted floodlight, IP66 is usually the more relevant rating. A dual rating such as IP66/IP67 covers both.
Why is there condensation inside my IP65 floodlight?
Condensation usually comes from thermal cycling. As the floodlight cools, the air inside contracts and draws in moist air through a weak seal, a loose cable gland or along the cable itself. Check the gland and gaskets, and have an electrician inspect the fitting if moisture keeps returning.
Can I hose down an IP65 floodlight?
An IP65 floodlight is tested against a low pressure water jet, so a gentle rinse with a garden hose is within its rating. Do not use a pressure washer, which is far more severe than the IP65 or IP66 tests and can force water past the seals.
Do I need an electrician to install an outdoor floodlight in Australia?
Yes, if the floodlight is hardwired. Fixed electrical wiring in Australia must be carried out by a licensed electrician, who will also make sure the cable entry, connections and circuit protection suit an outdoor location under AS/NZS 3000.
