Indoor vs Outdoor LED Neon Signs: IP Ratings & Weather Resistance

Not sure if you need an indoor or outdoor LED neon sign?

LED neon signs look similar indoors and out, but the differences in IP rating, power supply, mounting, and material matter — especially in Canada where weather conditions are demanding. This guide covers everything you need to know before choosing an indoor or outdoor LED neon sign.

At a glance

Indoor LED Neon

Controlled environments

IP20 or unrated — not weather resistant
Standard low-voltage power supply (12V or 24V DC)
Lighter mounting hardware required
Wider colour and finish options
Lower cost overall

Outdoor LED Neon

Exposed environments

IP65 rated minimum — dust and rain resistant
Weatherproof power supply and sealed connections required
Corrosion-resistant mounting hardware
Rated for –20°C to +40°C (Canadian winters included)
Higher upfront cost; longer lifespan outdoors

Understanding IP ratings for LED neon signs

IP20

Indoor only

Protected against solid objects over 12mm. No moisture protection whatsoever.

Bedrooms, studios, offices

IP44

Splash resistant

Protected against solid objects over 1mm and water splashing from any direction.

Bathrooms, kitchens, patios

IP65

Outdoor standard

Fully dust-tight and protected against low-pressure water jets. The minimum rating for outdoor LED neon in Canada.

Nightglow outdoor signs

IP67

Submersion resistant

Fully dust-tight and protected against temporary immersion up to 1 metre for 30 minutes.

Flood-prone or coastal areas

IP68

Continuous submersion

Highest rating — fully dust-tight and rated for continuous underwater use beyond 1 metre.

Specialty / industrial only

Full comparison: indoor vs. outdoor LED neon

Factor	Indoor LED Neon	Outdoor LED Neon
Protection & Weather Resistance
IP rating	IP20 (standard indoor) — no moisture protection	IP65 minimum — dust-tight and rain resistant
Rain resistance	None — must be kept dry	Rated for direct rain and low-pressure water jets
Snow & ice	Not suitable for any exposure	Rated for Canadian winter conditions down to –20°C
UV resistance	Standard silicone — may yellow over time in sunlight	UV-stabilised silicone maintains colour in direct sun
Wind & vibration	Not rated for wind exposure	Flexible silicone absorbs vibration; mounting hardware rated for wind load
Power & Electrical
Power supply type	Standard indoor-rated 12V or 24V DC transformer	Weatherproof (IP65+) sealed power supply required
Voltage	Both use low-voltage DC (12V or 24V) — safe for plug-in use
cUL certification	cUL-certified power supplies available — required by most Canadian landlords and insurers	cUL-certified weatherproof power supplies available for outdoor installs
Power consumption	Comparable — typically 10–25W depending on sign size; outdoor signs may draw slightly more due to longer runs
Installation type	Plug-in (standard outlet); hardwiring optional	Plug-in to weatherproof outlet, or hardwired by a licensed electrician (required in BC for hardwired installs)
Mounting & Installation
Mounting hardware	Standard acrylic backing, wall anchors, or hanging wire	Corrosion-resistant stainless or galvanized hardware; sealed cable entry points
Surface compatibility	Drywall, wood, brick, acrylic — most interior surfaces	Brick, concrete, metal, wood — all standard exterior surfaces; sealant required around entry points
Permit requirements	Generally not required for plug-in indoor signs	Sign permits required in most BC municipalities before installation; Vancouver By-law No. 11879 applies
Professional install needed	Most indoor signs are DIY-friendly with plug-in power	Hardwired outdoor installs require a Technical Safety BC–registered electrician
Appearance & Customization
Colour options	Full range — all colours and RGB options available	Most colours available; some specialty finishes are indoor-only
Backing options	Clear, black, white, or mirrored acrylic; wood; custom shapes	Clear or black acrylic (sealed); metal backing available for heavy-duty installs
Size limits	No practical size limits for indoor use	Larger signs may require structural assessment and additional mounting points
Cost & Longevity
Upfront cost	Lower — standard components and hardware	Higher — weatherproof power supply, sealed connections, and corrosion-resistant hardware add cost
Lifespan	50,000+ hours in a clean indoor environment	50,000+ hours; UV-stabilised materials resist degradation better long-term outdoors
Maintenance	Wipe clean as needed; no special maintenance	Periodic inspection of seals and mounting hardware recommended, especially after harsh winters
Warranty	Nightglow Studio offers a 2-year warranty on all signs, indoor and outdoor

Frequently asked questions

Can I use an indoor LED neon sign on a covered patio?

It depends on how sheltered the space is. A fully covered patio with no direct rain exposure may be fine with an IP44-rated sign. For any space with even occasional moisture exposure, we recommend IP65 as a minimum. If in doubt, choose outdoor-rated — it costs a little more but lasts significantly longer.

What IP rating do I need for outdoor signage in Canada?

IP65 is the standard minimum for outdoor LED neon signs in Canada. It protects against rain, dust, and the freeze-thaw cycles common in BC winters. IP67 or higher is only needed for signs in flood-prone areas or locations subject to high-pressure washing.

Do outdoor LED neon signs work in cold weather?

Yes. Nightglow's outdoor signs are rated for temperatures down to –20°C, which covers most Canadian winter conditions. The flexible silicone tubing maintains its shape and brightness in cold weather without cracking.

Do I need a permit for an outdoor LED neon sign in BC?

In most BC municipalities, yes — a sign permit is required before installation, not after. In Vancouver, the Sign By-law No. 11879 governs outdoor signage. Fines apply for unpermitted signs. Nightglow recommends checking with your local municipality before installing any exterior sign.

Can any LED neon sign be converted from indoor to outdoor use?

Not reliably. Indoor signs use standard silicone and non-weatherproof power supplies that aren't rated for moisture or UV exposure. The safest approach is to order an outdoor-rated sign from the start. Nightglow can advise on the right spec when you request your free mockup.

Bottom line: If your sign will be exposed to rain, snow, direct sun, or temperature extremes, always choose an IP65-rated outdoor LED neon sign with a weatherproof power supply. Indoor signs are not designed for outdoor conditions and will fail prematurely. Not sure which applies to your space?
