Can You Use Party Lights Outside? A Guide to IP Ratings & Outdoor Safety

Are outdoor party lights safe? Are waterproofing party lights really rain-proof?

If you are thinking of using party lights in your backyard, outdoor venue or in any other application where it can be exposed to the elements, you are likely worried about the risk of damage or safety posted by your choice of lighting.

Here at DJ City, we stock a wide range of affordable, effective and completely safe waterproof party lights that are perfect for any occasion.

Are Outdoor Party Lights Safe?

Yes, the right outdoor party lights are completely safe in the rain.

It is important however to:

  • Purchase reputable brands of outdoor party lights
  • Buy party lights from a known supplier
  • Check the IP-rating of your outdoor gear

What is an IP-rating?

IP stands for: Ingress Protection.

It is an international classification code that tells you how well the electrical enclosure of the lighting equipment, or other product, is protected against solid objects (such as dust) and liquid (like rain).

For party lights, this is the big difference between indoor‑only light fixtures and weather‑resistant outdoor party lights.

What Are the Different IP Ratings and Which Are Safe for Outdoor Party Lights?

1. IP20: Indoor lights only

An IP rating of IP20 indicates indoor-use only.

The 2 indicates that the electrical equipment has basic protection against fingers and medium‑sized objects. The 0 means it does not have protection against water (or dust). If exposed to rain or water, the live components and electronics can be damaged and there may even be a risk of shock and injury upon contact.

Examples of typical lighting with an IP20 rating:

  • Disco balls
  • Cheap pars
  • Lounge, bar or stage effect lighting

2. IP20: Outdoor party lights 

An IP-rating of IP65 indicates that the lighting is safe for use outdoors. The 6 refers to the protection from dust, whilst the 5 indicates that it is insulated from low-pressure water from any direction. This is why IP65 lights are the right choice for outdoor gigs and parties.

It offers full protection from light rain, splashes, hose mist, dew, and even damp coastal air.

It is ideal for use:

  • On patios
  • In gardens
  • Along driveways
  • With marquee exteriors
  • Or as building washes.

If you need waterproof party lights, make sure any fixture under consideration is labelled IP65 as well as weatherproof and suitable for outdoor use.

Can You Use Indoor Lights Outside With an Extension Cord?

Using indoor lights outside and running an extension cord is neither safe nor smart.

It is one of the more common DIY mistakes and it contributes to the nervousness surrounding outdoor party lights’ electrocution and damage risks.

  • Indoor lights have open vents, exposed switches and non-sealed components making them susceptible to water and rain
  • Often the joins and power boards are also not waterproof
  • Power boards can fill up with water, even if not directly exposed
  • Tape is not effective for waterproofing connections and joins
  • Extension cords also present a tripping hazard, especially in the dark
  • Power cords can be accidentally pulled on and turn off or destroy the lighting

If the lights are specifically determined for indoor use only, we highly recommend only using them indoors.

Using them outdoors even under a patio or roof  can void the warranty, cause damage to the lighting and present a safety risk.

For stress-free and lost cost outdoor party lights, there is no need for corner-cutting. DJ City is here to help you find the perfect waterproof party lights for your needs.

What About Solar Party Lights?

Solar party lights are becoming more and more popular. Whilst a low maintenance option, for sure, there are some pros and cons.

Pros of Solar Party Lights

  • Independently powered.
  • Low running cost
  • Good for gentle ambience lighting

Cons of Solar Party Lights

  • Operation time and output can be limited
  • Often less colour-flexible or customisable
  • Not suitable for big or high-energy parties alone

But when it comes to safety, the same rule applies: Make sure that, even though it is assumed to be designed for outdoor use, that your choice of solar party lights are:

  • Made for the outdoors
  • Fully sealed
  • Properly IP-rated (i.e., IP65)
