IP65 vs IP67 — Which Outdoor LED Neon to Choose?
IP65 vs IP67 — Which Outdoor LED Neon to Choose?
Choosing an LED neon for outdoor mounting requires understanding one critical specification — the IP ingress protection rating. These two digits decide whether your sign will survive a wet British autumn, side-driven March rain or a 30°C August heatwave. In this article we explain the differences between IP65 and IP67 based on the EN 60529 (PN-EN 60529 in Poland) standard, walk through real installation scenarios (facade, awning, pool, garden) and advise when paying extra for a higher rating is worth it and when it is pure waste. This knowledge translates directly into installation lifespan and the validity of the manufacturer’s warranty.
What is the IP rating — the EN 60529 standard
The IP (Ingress Protection) marking defines two independent values for an electrical enclosure’s resistance. The first digit covers solid objects (dust, grit, sand grains), the second — water. The EN 60529 standard precisely defines the test conditions for each level — from the nozzle diameter of the water jet, through exposure time, all the way to the depth of water immersion.
Importantly — IP values are not a linear scale. IP67 is not “better” than IP66 in every scenario. IP66 protects against powerful high-pressure water jets (e.g. a pressure washer), while IP67 provides resistance against short-term immersion — these are two different tests with different risk profiles.
First IP digit — protection against solid objects
| First digit | Protection against solid objects | Practical scenario |
|---|---|---|
| 4 | Foreign solid objects >1 mm | Wires, screws, larger grit |
| 5 | Dust-protected | Dust does not harm but can enter |
| 6 | Dust-tight | Zero dust inside the enclosure |
All outdoor neons we offer in our outdoor neon category have a first digit of at least 6 — that is, full dust-tightness. Over a long horizon dust is more destructive than water, because it settles on the PCB and forms creepage paths for leakage current.
Second IP digit — protection against water
| Second digit | Test conditions (EN 60529) | Real-world exposure |
|---|---|---|
| 4 | Water splashes from any direction | Bathroom, kitchen (zone II) |
| 5 | Water jets from a 6.3 mm nozzle, 3 min, 12.5 l/min | Rain, balcony awning |
| 6 | Powerful pressurised jets from a 12.5 mm nozzle, 3 min, 100 l/min | Facade, pressure washing, storm |
| 7 | Short-term immersion 1 m, 30 min | Pool, fountain, waterside installation |
| 8 | Continuous immersion above 1 m | Aquarium, underwater |
IP65 — semi-outdoor neon and awning installations
An IP65 neon is dust-tight and resistant to water jets at normal pressure — that is, typical rain, snow and drizzle. It is ideal for situations where water may fall onto the neon’s surface, but not under pressure and not with full frontal impact.
- Balcony awning or roof eaves — full protection, neon partially shielded
- Shop window from the inside — glass protects against frontal rain
- Restaurant entrance under a roof — typical hospitality signage location
- Signage in a driveway gateway — partial shielding, side-driven rain
- Logo on a facade under a cornice — the cornice drains water away
IP65 is also the most common rating for bathroom neons in zones 1 and 2 — zones where water does not strike directly under pressure but is a constant element of the surroundings (steam, shower droplets).
IP67 — full resistance to frontal rain and immersion
An IP67 neon withstands short-term immersion in water up to 1 metre for 30 minutes. In practice this is absolute protection for a typical European outdoor installation — against torrential rain, snow melting on the structure or flooding during heavy storms.
- Fully exposed facade signs — no shielding, frontal rain, wind
- Neons near pools and fountains — water spray, possible flooding
- Garden installations — near sprinklers, water features
- Pole-mounted signs in car parks — full precipitation exposure
- Neons on a facade without a cornice — vertical wall, water runs down the neon
Bear in mind that IP67 protects against short-term immersion, but not against continuous submersion — for aquariums or fountains with a permanently submerged neon you need IP68, which we do not offer as standard due to its niche use case.

When IP44 is enough — the indoor neon
If the neon is destined to glow in a living room, bedroom, office, restaurant or club — that is, an indoor space without direct water exposure — IP44 is sufficient. Specifying an IP67 neon for an interior room is spending money without added value; immersion protection does not activate in any real-world scenario.
Exceptions are rooms with elevated humidity — bathroom (zones 1 and 2), kitchen near the sink, indoor pool — where a minimum of IP65 is advisable. In our neon creator the system automatically suggests an IP class once you indicate the installation location.
FAQ — common questions about IP65 and IP67
Can I mount an IP44 neon under a covered canopy outdoors?
We do not recommend it. Even under a canopy, outdoor humidity (fog, dew, condensation) is far higher than indoors, and day/night temperature swings generate condensate inside the enclosure. An IP44 neon is designed for room conditions, and mounting it outdoors voids the manufacturer’s warranty — we require a minimum of IP65 for any location outside the interior of a building.
Is IP67 really necessary on a typical facade?
Yes — particularly in Central Europe, where wind-driven side rain (typical for autumn and spring) forces water in at every angle. IP66 is the safe minimum, but IP67 gives an additional margin for extreme cases (cloudbursts, blocked gutters above the neon, snow melting on the structure). The price difference between IP66 and IP67 is typically 10-15% — well worth it for a 5-year investment.
Does the power supply also need the same IP rating as the neon?
Ideally — yes. If you mount the driver underneath the neon on the facade, it should be IP65 or IP67. However, a common practice is to place the driver inside a mounting box with separate IP protection — in which case the driver itself can have a lower rating (IP20 for indoor use). In our complete outdoor neon kits the driver is always matched in rating to the installation scenario.
Will IP65 survive a Central European winter?
Yes, but with a caveat — IP65 protects against water, not against frost. All our neons intended for outdoor use have an operating range from -25°C to +50°C, which covers typical Polish and Central European conditions. The problem is not frost in itself, but the freeze-thaw cycle when water has already penetrated through a weak seal. That is why for an unshielded facade we strongly recommend IP67.
How can I be sure the declared IP rating is genuine?
Every one of our neons passes a conformity check against the declared IP rating, and the manufacturer issues an EU Declaration of Conformity (CE) together with technical documentation aligned with EN 60529. The full documentation is available on our certifications page — in case of inspection by sanitary, tax or building authorities you have a complete file ready.
What if the neon stops working after a year outdoors?
If you bought a neon with a rating matching the installation location (IP65 for an awning, IP67 for a fully exposed facade) and no mechanical interference has occurred — our 24-month manufacturer’s warranty applies. We describe the claim process in detail on the complaints page. Standard repair or replacement time is 7-14 working days.
