IP Ratings for Garden Lights Explained

IP54 means a light fixture is protected against dust (a small amount may get in, but not enough to affect how it works) and against splashing water from any direction. The first digit of the IP code tells you how well it is protected against dust and solid objects, and the second how well it is protected against water. For the garden, the simple rule is: IP44–IP54 under the eaves or on a covered terrace, at least IP65 wherever the light stands in the rain, IP67 for in-ground spotlights and IP68 for lighting submerged in water.

Outdoor lighting matters as much for the look of your garden as for safety on paths, steps and around the entrance. For your lights to last for years, they need to be chosen by their IP rating (Ingress Protection), as defined by the international standard IEC 60529.

What an IP rating means

The IP code is made up of two digits:

• The first digit (0–6) shows protection against solid objects and dust. From 5 upwards we are talking about dust: 5 means “dust-protected”, 6 means “dust-tight”.
• The second digit (0–9) shows protection against water: from drops falling vertically to powerful jets, temporary immersion (7) or continuous immersion (8).

If the letter X appears instead of a digit (IPX4, for example), it means the product has not been tested for that type of protection – not necessarily that the protection is missing. The images below sum up what each digit means.

IP44, IP54, IP65, IP67, IP68: what each one means

IP code	Protection against dust and solids	Protection against water	Where to use it in the garden
IP44	Objects larger than 1 mm	Splashes from any direction	Verandas, covered terraces and balconies, under the eaves
IP54	Dust-protected (limited ingress does not affect operation)	Splashes from any direction	Partly exposed walls, areas only occasionally reached by rain
IP65	Dust-tight	Water jets (6.3 mm nozzle)	Façades, paths, bollards and wall lights directly exposed to rain
IP66	Dust-tight	Powerful water jets (12.5 mm nozzle)	Areas hosed down or very exposed to the weather
IP67	Dust-tight	Temporary immersion (up to 1 m, 30 minutes in testing)	Spotlights set into or close to the ground, where water can collect
IP68	Dust-tight	Continuous immersion, under conditions stated by the manufacturer	Fountains, ponds, swimming pools (underwater lighting)

A useful detail: for water, the ratings do not automatically “add up” beyond 6. An IP67 product has been tested for immersion, but not necessarily for water jets as well. That is why some manufacturers mark both tests, for example “IP65/IP67”. If an in-ground spotlight will also be hosed down, look for this double marking on the technical data sheet.

What IP rating you need for outdoor lighting

To work safely outdoors, a light fixture has to be chosen according to how exposed its mounting position is:

• IP44 – protection against splashes and small solid particles. Suitable for semi-covered areas: verandas, covered terraces, balconies.
• IP54 – greater protection against dust and splashes, for areas occasionally exposed to the weather.
• IP65 – dust-tight and protected against water jets. The standard choice for paths, façades and open spaces exposed to rain.
• IP67 – dust-tight and protected against temporary immersion. Recommended for lights set into the ground or wherever water may pool.
• IP68 – the highest level of water protection, for continuous immersion. Essential for underwater lighting in fountains, ponds and swimming pools.

Choosing garden light fixtures, area by area

Where the light goes	Minimum recommended IP	What else to check
Wall light under the eaves or on a covered terrace	IP44–IP54	If the wind drives rain onto it, go for IP65
Wall light on an exposed façade	IP65	The housing material (painted aluminium, stainless steel) and the seal
Bollards and path lights	IP65	How it is fixed to the base and where the cable enters
Recessed in-ground spotlights	IP67 (ideally IP65/IP67)	Drainage beneath the spotlight and whether it can be walked on
Spike spotlights for trees and shrubs	IP65 or higher	The cable and connectors must also be rated for outdoor use
Fountains, ponds, swimming pools	IP68	Extra-low voltage and installation by a qualified electrician

Outdoor wall lights

Wall lights by the front door, on the terrace or on the façade are usually the first to be chosen. Under deep eaves, IP44 or IP54 is enough. On an open wall where the rain beats down directly, choose IP65. In our range of outdoor wall lights, the IP rating is listed on each product's technical data sheet, so you can compare models side by side.

Bollards and path lights

Bollards and path lights stand out in the rain, dust and snow all year round, so they need at least IP65. For a path that is comfortable to walk along, low lights between 50 and 80 cm tall light the way without dazzling. Space them evenly and keep them on the same side of the path for a tidy look.

In-ground spotlights

Outdoor spotlights set into the ground need IP67 or IP68 to cope with moisture in the soil and the water that collects after rain. Lay a bed of gravel beneath the spotlight so water can drain away, and if it sits on a path or terrace that people walk on, check the technical data sheet to see whether the manufacturer declares it suitable for this.

Lighting for fountains and swimming pools

For lighting in water, the only correct choice is IP68. Electrical installations in swimming pools and fountains are subject to special safety rules, with extra-low voltage and additional protection, so installation must be carried out by a qualified electrician.

Practical tips before you buy

• Look at the IP rating of the whole installation, not just the light: outdoor junction boxes and connectors must also be rated for outdoor use.
• Installation matters. An IP65 light fitted incorrectly, with a crushed seal or the cable entering from the top, loses its protection.
• Residual current protection. Outdoor circuits should be protected by an RCD (residual current device); ask your electrician to include one.
• Warm light (around 3000 K) creates a welcoming atmosphere in the garden, while neutral light (4000 K) is better suited to work areas or parking spaces.

Frequently asked questions

What does IP54 mean?

The 5 means protection against dust: a little dust may get in, but not enough to affect operation. The 4 means protection against splashing water from any direction. IP54 is good for partly sheltered areas, not for direct, continuous rain.

What does IP65 mean?

IP65 means dust-tight (6) and protected against water jets (5). It is the most widely used rating for wall lights, bollards and floodlights installed outdoors.

Is IP44 suitable for outdoor use?

Yes, but only in covered spots: under the eaves, on a veranda or on a covered balcony. IP44 withstands splashes, not water jets, so for a wall directly exposed to rain choose IP65.

What is the difference between IP67 and IP68?

IP67 withstands temporary immersion, tested at a depth of no more than 1 m for 30 minutes. IP68 withstands continuous immersion, under conditions (depth, duration) stated by the manufacturer and tougher than those for IP67. For in-ground spotlights IP67 is usually enough; for lighting in fountains or swimming pools you need IP68.

What does the X in IPX4 mean?

The X shows that the product has not been tested for that category. IPX4 means that protection against dust has not been declared, but protection against splashing water is there.

Choosing the right IP rating ensures durability and safety in every season. Whether you are lighting paths, the façade or decorative features in the garden, compare the IP rating first, then the design. If you are also doing up your bathroom, read our guide to IP ratings for bathroom lighting.
