Shopping for outdoor string lights? You’ll probably come across two important ratings: IP44 and IP65. In a nutshell, these ratings tell you how well the lights can handle stuff like water and dirt. While both IP44 and IP65 withstand water splashes and solid objects, like dirt, IP65 rated lights are tougher. For example, they can withstand even heavy rain, though you should never dunk them underwater.
Why understanding these ratings is important? Well, for one, non-rated festoon lights or those that have a lower IP rating than 44 are not suitable for outdoor use. Using them increases the risk of fire, which I am sure is the last thing you want when installing outdoor lights for a get-together. Sub-standard lights often also increase the risk of power surges, arc faults, and other severe consequences.
In this post, we’ll demystify IP ratings and show you how you can select safe and long-lasting outdoor lights.
IP Ratings Explained
IP rating is made up of two numbers and denote how resistant an electrical device, like festoon lights, is to water and solids. The higher the IP rating of an electrical device, the more resistant it is to the elements. This is why IP65 rated festoon lights offer better protection than IP44 lights. That said, IP44 lights are perfectly suitable for outdoor use. But anything lower than that is not. Therefore, when you are shopping for outdoor lights, look whether it is IP rated or not and if it is, what its IP rating is.
If an outdoor light is not IP-rated, stay away from it. The same goes for outdoor festoon lights that are IP rated but have a lower rating than IP44.
IP44 Rating Explained
An IP44 rated electrical device is resistant to most solid objects. It also possesses the ability to withstand light rain or water splashes.
IP65 Rating Explained
An IP65 rated electrical device offers the same level of protection against solid objects as an IP44 rated device. But compared to the latter, it offers better protection against water. However, keep in mind IP65 lights aren’t build to withstand submersion in water.
IP44 vs. IP65 Festoon Lights — Which One You Should Pick?
If you’re planning to install festoon lights outdoor, you can pick either IP44 or IP65 rated lights. However, if you want greater protection against water, IP65 rated festoon lights are the right fit for you.
