In these times of rapidly-developing LED technology, it can be difficult to keep up with all the terminology. Here at LED Monkey HQ, we like to make things as easy as possible for you, which is why we created this article to keep you informed about IP (Ingress Protection) Ratings, so read on…

 What exactly is an Ingress Protection Rating?

The Ingress Protection or “IP-Rating” of electrical enclosures like LED Light Bulbs and fittings, denotes the level of its protection from solid objects and liquids (usually water).

With bulbs and fittings that are to be used in bathrooms, kitchens and outdoors, you need to know whether  they'll function properly when subjected to the incessant moisture and dampness of the British weather, so that’s where IP-ratings come into play!

Every electrical enclosure is given an IP-rating consisting of two numbers, which you’ll find clearly marked on the packaging of all our IP-rated products.

What do the two numbers signify?

Both the digits that follow the prefix “IP” has a significance; the first tells us the enclosure’s degree of protection from foreign (solid) bodies. As you’ll see in the table below, this can mean anything from the finest dust, to a sledgehammer!

The second digit indicates the level of protection you can expect against moisture, such as drips, sprays and submersion etc.

So, here are two tables illustrating the various IP-Ratings and what they signify:

1st Number Level of Protection from Solid Objects
0 None.
1 Protection from a large part of the body like a hand, but no protection from deliberate ingress. Protection against solid objects larger than 50mm.
2 Protection against fingers or other objects, not greater than 80mm long and 12mm wide.
3 Protection from entry by tools, wires etc, with a width of 2.5 mm or more.
4 Protection against solid bodies larger than 1mm (fine tools like screwdrivers and wires etc).
5 Protected from dust.
6 Completely dust-tight.
2nd Number Level of Protection from Moisture
0 None.
1 Protection given from condensation and air-bound moisture.
2 Protected against water droplets, deflected up to 15° from vertical.
3 Protected against liquid sprayed up to 60° from vertical.
4 Protection given from liquid sprayed from any direction.
5 Protected against low-pressure jets of liquid from any direction.
6 Protection from strong jets and waves of liquid.
7 Protected against temporary, short-term immersion in a liquid (up to 1-metre).
8 Protected against the prolonged effects of complete immersion, under pressure (beyond 1-metre).

So, if you’re looking for an LED Bulb for your bathroom or for the exterior of your home, you’ll want one that has a fairly high second number. For this purpose, we recommend an IP67-rated bulb, as not only will it be totally dust-tight, it will also resist water exceptionally well.
