Weatherproof silicone tube, free 3D mockup, 3-year warranty, 10 to 14 day delivery." url: https://helioneon.com/en/neon-signs-for-business/outdoor-ip65/ --- # Waterproof outdoor LED neon IP65 made to measure Professional signage that stands up to every season and façade décor built to last: a neon designed, sealed and guaranteed for life outdoors. Driving rain, frost, UV, condensation, your neon holds firm. - 3D mock-up within 24 h - Delivered in 10 to 14 days - 3-year warranty - Certified IP65 waterproofing ## Why not every LED neon survives outdoors Many LED neons sold as "outdoor" are actually indoor models coated in a thin layer of silicone. Fitted on an exposed façade, they fail within a few months. Four enemies attack a **waterproof outdoor LED neon** every day. Driving rain seeps in through poorly sealed joints and connectors. UV rays bleach low-grade silicone and make it brittle within two years. Frost expands micro-pores and cracks the junctions. Condensation, more insidious still, settles inside the tube and clouds the light. A true outdoor neon is not a product, it is an assembly: monobloc silicone tube, remote IP65 power supply, heat-sealed connectors, ventilated acrylic mount. At Helioneon, every link in the chain is validated for outdoor use. Not an IP sticker stuck on an indoor product. They trust us for their outdoor signs ## The IP rating that changes everything: certified IP65 The IP rating, defined by the [IEC 60529 standard](https://fr.wikipedia.org/wiki/Indice_de_protection), measures how well an electrical product is protected against dust and water. The higher the second digit, the stronger the water protection. For a neon that lives outdoors, it is the only indicator that matters. **IP65 is the standard we apply to every outdoor neon we make**. In practical terms: total dust protection, and full resistance to water jets in every form (driving rain, high-pressure washing, sea spray, garden splash). It is the right level for 100% of professional signage projects, shop façades, restaurant terraces, residential gardens and outdoor events. ### Helioneon indoor neons All our standard indoor neons are IP44 protected: enough for a ventilated bathroom, kitchen, changing room or any dry to moderately humid interior. No surcharge, no option to tick. ### Helioneon outdoor neons Our outdoor version steps up to certified IP65: water jets, driving rain, frost, UV, weather from the north-east as much as the coast. Waterproofing certificate supplied with every outdoor order. **No IP67 or IP68 in our catalog**, and that is not a gap: those ratings only make sense for fully submerged products (fountains, permanently filled pools). For everything else, IP65 is the only relevant level, and it is the one we stand behind on every outdoor neon that leaves our workshop. ## Uses for a waterproof outdoor LED neon An IP65 rating opens up settings no indoor neon can handle. Here are the projects our customers order most. ### Restaurant and terrace bar signage Logo, name or slogan on the façade or hung over the terrace. Long-range visibility, instant atmosphere, strong identity. See our [restaurant neon](https://helioneon.com/en/neon-signs-for-business/restaurant/) or [bar neon](https://helioneon.com/en/neon-signs-for-business/bar/) page. ### Storefront and window display Permanent illuminated signage exposed to rain and sun. Our IP65 replaces traditional light boxes with a more modern graphic signature. Details on the [retail neon](https://helioneon.com/en/neon-signs-for-business/retail/) page. ### Garden and residential terrace A quote, the house name, a pergola outline, pathway signage. The neon survives storms and north-eastern winters with no visible change. ### Outdoor events and festivals Outdoor wedding, festival, trade show under a marquee. The neon goes out, comes back, goes out again, with no degradation. Hire or buy depending on your needs. ### Swimming pool and pool house Pool edge outline, pool house wall, outdoor décor near water. Our IP65 standard handles splashes, spray and poolside mist without issue. ### Architecture and agency projects Façade cladding, office signage, open lobby. We work hand in hand with architects and design offices through our [business neon](https://helioneon.com/en/neon-signs-for-business/business/) offer. ## How Helioneon guarantees IP65 waterproofing IP65 is not declared, it is built. Here are the four waterproofing engineering steps that set apart our [neon signs for business](https://helioneon.com/en/neon-signs-for-business/) made for outdoor use. To go further, read our [installation guide](https://helioneon.com/en/installation-guide/). Food-grade high-density silicone, extruded in a single piece, with no seam or glue. No weak point where water can seep in. UV resistance tested for [100,000](https://helioneon.com/en/flexible-led-neon/) hours with no color shift. Each end is closed with a laser-welded silicone cap, not glued. A process drawn from the aerospace industry and adapted for signage. Waterproofing validated at the factory on 100% of units. Threaded connectors with O-ring seals, no terminal blocks or Wago connectors. The cable exits the neon through a cable gland, never through a cut made with a knife. IP65 rating maintained all the way to the power supply housing. A 12V or 24V IP65 waterproof power supply is always included, never an indoor PSU "to protect yourself". Aluminum housing withstands thermal shock from -25 °C to +50 °C. 3-year parts warranty, identical to the neon. ## Pricing and lead times for a custom outdoor neon The ranges below reflect real projects delivered in 2025-2026, excluding installation.
