This light has an IP Rating - what does it all mean ?
IP rating stands for “Ingress Protection” or “International Protection”. This is a standard rating that determines how waterproof and dust / solid object proof a light fitting is.
The first digit in an IP rating refers to how dust proof a fitting is and the second digit refers to how waterproof a fitting is. With the 2 numbers combined this will determine the likelihood of any foreign objects getting into the light fitting and possibly damaging it.
Below is a table, which represents the various levels of protection as well as what each number means. Generally speaking, high-end outdoor lighting will be IP rated 67 or 68, however a rating of 44 will be suitable for general outdoor use though preferably not exposed directly to heavy rain.
|Number ||First Digit ||Number ||Second Digit |
| ||Protection against ingress of solids || ||Protection against ingress of water |
|0 ||No Protection ||0 ||No Protection |
|1 ||Protected against solid objects over 50mm in size. Eg large tools ||1 ||Protected against vertically falling drops of water |
|2 ||Protected against solid objects over 12mm in size. Eg fingers and hands ||2 ||Protected against direct sprays of water with light tilted 15 degrees from vertical - light rain |
|3 ||Protected against solid objects over 2.5mm in size. Eg wires and small tools ||3 ||Protected against direct sprays of water with light tilted 60 degrees from vertical - strong rain |
|4 ||Protected against solid objects over 1mm in size. Eg wires and bugs ||4 ||Protected against sprays of water from all directions - gentle spray with a hose pipe |
|5 ||Limited protection against dust ingress - harmfull amounts cant get in. ||5 ||Protected against low pressure jets of water from all directions - strong spray with hose pipe |
|6 ||Totally protected against dust ingress - dustproof ! ||6 ||Protected against strong jets of water from all directions - cleaning light with high pressure hose |
|7 || ||7 ||Protected against temporary immersion in water no deeper than 50cm - bit of flooding |
|8 || ||8 ||Protected against continuous immersion in water no deeper than 100cm - pool or pond light |
