Reputable manufacturers of power devices like LED drivers and transformers prioritize safety and longevity in the design phase because low voltage does not necessarily mean low risk. Safety classifications such as UL, Class 2 and Class P (discussed in our previous blog) are important to consider, but what about enclosure ratings for lighting systems installed in outdoor settings?

What LED Driver Ratings Are Important for Outdoor Installations?

While KSPOWER LED drivers rated for outdoor settings can also be installed indoors, the same is not true in reverse. This is because our outdoor power solutions are certified for either NEMA 3R, IP65, IP66 or IP67 which means they have been tested under various conditions.

What’s the Difference between IP and NEMA 3R?

KSPOWER’s H/L Series is rated for IP65 IP67, and our NT Series Recognized is rated for NEMA 3R. Designated by Underwriters Laboratories, IP is an international standard that uses a 2-digit numbering system, and if you look at the above charts, you’ll see the comparable ratings of NEMA vs, IP. Like NEMA 3R, IP66 and IP67 protect against rain, sleet and snow but also airborne dust, heavy splashes and even temporary submersion on IP67. Knowing the environment your lighting installation will be exposed to is important to determine whether you need NEMA 3R or the higher level of protection that IP66 and IP67 offer.

Obtaining a NEMA or IP rating is a time-consuming and expensive process, which explains why many “cheap” drivers and transformers don’t include them. However, we all know that cutting corners may save money in the short term, in the long term, it can cost more with eroded parts and a shortened life span.
