Degrees of IP and IK protection
IP and IK standards. What does IP44, IP65, IP66 or IK10 mean?
When choosing a luminaire, it is important not only to consider the appearance of the luminaire, but also its compliance with the environmental conditions in which it will be used. If the luminaire is intended for lighting residential areas, e.g. a corridor, living room, bedroom, etc., luminaires with a class of IP20 are sufficient. For luminaires that will be in damp rooms, higher requirements apply – IP44 or higher classes. Outdoor luminaires intended for lighting facades, parks, streets or courtyards can be IP65, IP66, IP67. If the luminaires must be anti-vandal, resistant to mechanical impact – it is important to pay attention to the IK class of the luminaire.
IP protection degree (Ingress protection code) ![]()
The degree of protection of a luminaire, indicating its resistance to various external factors. The IP standard designation consists of the letters IP and two digits, which indicate the class of mechanical protection and protection against moisture of the electrical device.
First digit – Solid particle protection
Second digit – Liquid ingress protection
| Solid particle protection | Protection | Description |
| 0x | No protection | Not rated for protection |
| 1x | Protection against solid objects | Protection against solid objects larger than 50 mm, but not against deliberate contact (contact with open hand palm) |
| 2x | Protection against medium-sized objects | Protection against solid objects larger than 12 mm (contact from finger) |
| 3x | Protection against small objects | Protection against solid objects larger than 2,5 mm (wire or tools) |
| 4x | Protection against very small objects | Protection against solid objects larger than 1 mm (slender screws or nails, larger insects or potentially invasive small objects) |
| 5x | Protection against dust | Partial protection against dust and similar particles |
| 6x | Full protection against dust | Full protection against dust and other similar particles |
| Liquid ingress protection | Protection | Description |
| x0 | No protection | Not rated for protection |
| x1 | Protection against vertically falling water | Protection against vertically falling water droplets (condensation) |
| x2 | Protection against water, drops up to 15 degrees | Protection against vertically falling water droplets when tilted at 15 degrees |
| x3 | Protection against moisture spray water | Protection against moisture spray at up to 60 degree angles |
| x4 | Protection against splashing water | Protection against splashing water from any direction for at minimum 10 minutes |
| x5 | Water protection | Protection against low-pressure jets of water |
| x6 | Protection against powerful jets of water | Protection against powerful jets of water at a rate of 100 liters per minute (100 kPa of pressure at a distance of 3 m for 15 minutes) |
| x7 | Protection against immersion in water | Protection against full immersion up to 1 m in depth for 30 minutes. Always check manufacture specification for products with this rating |
| x8 | Protection against immersion in water | Protection against full immersion up to 1 m or more in depth for more than 30 minutes. Always check manufacture specification for products with this rating |
| x9 | Resistant to high-pressure, high-temperature water jets | Protection against flooding with a strong jet of water under pressure (80-100 bar and temp. +80 °C) |
IK Impact Protection (Mechanical impact resistance) ![]()
An international standard rating that defines an electrical enclosure’s resistance to mechanical impacts:
| IK rating | Impact energy (Joules) | Impact test details |
| 00 | No protection | No protection against mechanical impact. Luminaire is vulnerable to damage |
| 01 | 0,15 | Impact by a 0,25 kg mass dropped from 56 mm height |
| 02 | 0,20 | Impact by a 0,25 kg mass dropped from 80 mm height |
| 03 | 0,35 | Impact by a 0,25 kg mass dropped from 140 mm height |
| 04 | 0,50 | Impact by a 0,25 kg mass dropped from 200 mm height |
| 05 | 0,70 | Impact by a 0,25 kg mass dropped from 280 mm height |
| 06 | 1,00 | Impact by a 0,25 kg mass dropped from 400 mm height |
| 07 | 2,00 | Impact by a 0,5 kg mass dropped from 400 mm height |
| 08 | 5,00 | Impact by a 1,7 kg mass dropped from 300 mm height |
| 09 | 10,00 | Impact by a 5,0 kg mass dropped from 200 mm height |
| 10 | 20,00 | Impact by a 5,0 kg mass dropped from 400 mm height |
| 11 | 50,00 | Impact by a 10,0 kg mass dropped from 500 mm height |
