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|
