IP66 Waterproof Rating Explained: What You Need to Know
Shopping for a torch, you'll see ratings like IP66, IP67 and IP68 on the spec sheet. It's easy to assume any of them means "waterproof" — but each one says something specific about how much dust and water a torch can actually handle. Knowing what the IP66 rating means, and how it compares to IP67 and IP68, helps you pick a torch that survives the conditions you'll really use it in. Here's the plain-English version.
What is an IP rating?
IP stands for Ingress Protection — a standard set by the International Electrotechnical Commission (IEC 60529) that rates how well an enclosure keeps out solids and liquids. The rating is always two digits. The first digit describes protection against solids like dust, on a scale of 0 to 6. The second digit describes protection against water, on a scale of 0 to 9. So in "IP66", the first 6 is the dust score and the second 6 is the water score — both near the top of their scales.
What IP66 actually means
Two digits
The first digit rates protection from solids and dust (0–6); the second rates protection from water (0–9). Read them separately.
The first 6 = dust-tight
A 6 is the top solids score: the torch is fully sealed against dust ingress, with no particles getting inside at all.
The second 6 = water jets
A 6 means the torch withstands powerful high-pressure water jets from any direction — heavy rain, spray and a hose-down are no problem.
Not rated for submersion
IP66 covers jets and rain, not being submerged. For dunking or diving you need a higher water digit — IP67 or IP68.
For wet-weather cycling, IP66 is the sweet spot: the Fenix BC28R bike light carries exactly this rating — sealed against driving rain and road spray without paying for dive-grade sealing.
The "X" in IPX8
An X means that digit wasn't tested, not that there's no protection. IPX8 rates water only, with the dust score left unstated.
Higher isn't always needed
Match the rating to the job. For most land use IP66 or IP67 is plenty; reserve IP68 for water crossings and diving.
For a torch, IP66 means you can use it in heavy rain, hose it down and shrug off marine spray — but it is not rated to be submerged. If you expect to drop it in water or take it underwater, choose an IP67 or IP68 model instead.
How IP66 compares for torches
| Rating | Dust | Water | Typical torch use |
|---|---|---|---|
| IP65 | Dust-tight | Low-pressure water jets | Everyday outdoor use, rain |
| IP66 | Dust-tight | Powerful high-pressure jets | Heavy rain, hose-down, marine spray |
| IP67 | Dust-tight | Immersion to 1m for 30 min | Drops in puddles, brief submersion |
| IP68 | Dust-tight | Continuous immersion beyond 1m | River crossings, dive lights |
| IPX8 | Not rated | Continuous immersion (depth set by maker) | Water-focused lights, dust untested |
IP66 vs IP67 vs IP68
IP66 vs IP67
Both are dust-tight. The difference is the water score: IP66 handles powerful jets and rain but not submersion, while IP67 adds protection against temporary immersion in up to a metre of water for around 30 minutes. If you might drop your torch in a puddle or creek, IP67 is the safer floor.
IP66 vs IP68
IP68 is the highest common water rating, covering continuous immersion beyond one metre to a depth the manufacturer specifies. It's what dive lights and river-crossing torches carry. IP66 is more than enough for rain and spray, but it's not in the same class for underwater use.
The limits of an IP rating
An IP rating is tested in controlled lab conditions on a new, undamaged unit. Real-world performance depends on seals, O-rings and charge-port covers staying clean and seated, so grit, salt and wear can reduce protection over time. Treat the rating as a guide to design intent, keep covers closed, and rinse off salt water — and a well-rated torch will keep its sealing for years.

Frequently asked questions
What does the IP66 rating mean?
IP66 means a torch is fully dust-tight (the first 6) and withstands powerful high-pressure water jets from any direction (the second 6). It's excellent against dust, rain and spray, but it is not rated for submersion.
Is an IP66 torch waterproof?
It's highly water-resistant rather than submersible. An IP66 torch handles heavy rain, hosing and marine spray without trouble, but it isn't rated to be put underwater. For that you need IP67 or IP68.
IP66, IP67 or IP68 — which do I need for a torch?
For general outdoor and trade use in the rain, IP66 or IP67 is plenty. If you'll submerge the torch — river crossings, boating, diving — choose IP68. Match the water digit to how wet the job really gets.
Can I submerge an IP66 torch?
No — IP66 is not rated for immersion. Brief, accidental contact may be fine, but for deliberate submersion you should use an IP67 (temporary) or IP68 (continuous, depth-rated) torch.
What does IPX8 mean on a torch?
The X means the dust digit wasn't tested, while the 8 means the torch is rated for continuous immersion to a depth set by the maker. It tells you about water protection but not dust resistance.
Where can I buy a waterproof torch in Australia?
MaxBeam Australia stocks IP66, IP67 and IP68-rated torches from Fenix, Nitecore, Acebeam and more, shipped Australia-wide. Every torch is genuine Australian stock with full Australian warranty and local support — not grey-market import.
