Technical Guide
The short answer: quality LED house numbers are not just waterproof — they are weatherproof to IP65 standard, which is the correct and more meaningful rating for outdoor UK use.
IP stands for Ingress Protection, defined by IEC standard 60529. The rating tells you exactly how well a product resists dust and water. An IP65 rating means the product is fully dust-tight (rated 6 — the highest) and protected against water jets from any direction (rated 5). This covers driving rain, wind-blown water, and sustained UK winter weather.
| IP Rating | Liquid protection | Suitable for UK outdoors? |
|---|---|---|
| IP44 | Splash from any direction | Limited — not for exposed locations |
| IP54 | Water splashes, limited jets | Marginal — may fail in heavy rain |
| IP65 | Sustained water jets, any direction | Yes — fully suitable |
| IP67 | Temporary immersion up to 1m | Yes — overkill for most installs |
Important: The correct term for outdoor LED house numbers is 'weatherproof', not 'waterproof'. IP65 weatherproof is the correct and sufficient standard for all UK residential and commercial installations. Luxello illuminated house numbers are IP65 rated.
Fully protected against driving rain, wind-blown water, and sustained outdoor exposure. The correct standard for UK outdoor house numbers. All Luxello numbers are IP65 rated.
Without an IP rating number, "waterproof" is a marketing term that could mean anything from a basic splash rating to full immersion. Treat unspecified waterproof claims with caution.
A quality IP65-rated LED house number made from solid anodised aluminium should last 15–20+ years in UK outdoor conditions. The LED components typically have a rated lifespan of 50,000+ hours. Anodised aluminium will not rust, corrode, or fade — the anodising creates a hard oxide layer bonded to the metal surface.
Luxello illuminated house numbers carry a 10-year replacement parts guarantee — replacement LED panels are guaranteed available for a minimum of 10 years from the date of purchase. The metal housing lasts a lifetime; if an LED panel ever needs replacing, it can be ordered and fitted without replacing the entire number.
