An IP Rating – or Ingress Protection Rating – is a two-digit number used to show the degree of protection provided by the enclosures of electrical equipment, such as light fittings.
The first digit of the IP rating indicates a devices level of protection from solid objects such as a finger, screwdriver or contaminants like bugs and dust.
The second digit of the IP rating indicates a devices level of protection against water, ranging from small drops to complete immersion in water for long periods of time.
The IP Rating is important to consider when buying lighting, especially as this score, will determine where in the home a light can be used. Generally, a light with an IP Rating of greater than IP44 is required for the bathroom to protect against splashes and steam or covered areas outdoors such as patios and under eaves. For exposed outdoor lighting such as garden lights and wall lighting, an IP Rating of greater than IP67 is required to ensure it can stand up to the elements.
