What Is an LED Garden Luminaire? Types and Selection Criteria
An LED garden luminaire is an outdoor luminaire with a dust- and water-protected housing that lights garden paths, lawns, terraces and the area around buildings.
An LED garden luminaire is an outdoor luminaire with a dust- and water-protected housing, used to light garden paths, lawns, terraces, steps and the area around buildings. The light source can be an LED built into the housing, or the luminaire can have an E27 or GU10 lamp holder and be used with an LED lamp. Indoor wall lights and spotlights do not meet the protection needed outdoors.
Types of LED garden luminaire
| Type | Construction | Where it is used |
|---|---|---|
| Garden post luminaire | A luminaire on top of a post fixed to the ground | Paths in residential complexes, large gardens, car park edges |
| Lawn luminaire (bollard) | Short body that sends light sideways and downwards | Along footpaths, lawns |
| Garden wall light | Mounted on a wall | Entrances, terraces, building facades |
| Pillar-top luminaire | Sits on top of a garden wall or pillar | Garden walls, gate pillars |
| Recessed luminaire | Set into soil, concrete or paving, shines upwards | Highlighting trees, facades and path lines |
| Solar garden luminaire | Runs off-grid with a solar panel and battery | Places where no cable can be laid |
Selection criteria
- IP rating: IP65 (dust-tight, protected against water jets) is common for post, wall and lawn luminaires exposed to rain. For luminaires recessed into the ground, where water can collect, IP67 or higher (protected against temporary immersion) is required.
- Impact and load resistance: For a luminaire recessed into ground that people walk or drive over, the data sheet must state whether it can be stepped on and what load it withstands. In public areas, check the IK impact rating.
- Integrated LED or lamp holder: With an integrated LED, power and colour temperature are fixed, and on failure the LED module or the luminaire is replaced. With a lamp holder you choose the lamp later; do not exceed the maximum lamp wattage on the label.
- Light colour: Warm white (3000 K) is common in landscaping. Coloured models such as green and amber are available for highlighting plants and for decorative use.
- Supply: Use cable suitable for underground laying and sealed connections for a supply that runs under the ground, and protect the outdoor lighting circuit with a residual current device. On solar luminaires, the wattage in the name may not reflect the light output; compare lumen values instead.
Common mistakes
- Using an indoor luminaire outdoors: Moisture gets into the housing and the driver and LED soon fail.
- Setting a recessed luminaire into ground without drainage: Water collects underneath; leave a gravel or drainage layer.
- Joining cables in the soil with tape: Use a sealed joint or junction box.
- Lighting a footpath with powerful upward-facing luminaires: They cause glare; a lawn luminaire that sends light downwards suits a path better.
- Placing a solar luminaire in the shade: If the panel does not get sun all day, the battery does not charge.

IP ratings are defined in IEC 60529 and IK impact ratings in IEC 62262.

Frequently asked questions
Which light colour should an LED garden luminaire have?
For garden and path lighting, warm white (3000 K) is common and gives a warm look. If whiter light is wanted for security, 4000 K or 6500 K can be chosen.
How long does a solar garden luminaire stay lit?
It depends on the battery capacity, the sun the panel gets and the light setting. The time given in the data sheet is for a full charge; it is shorter in winter and on cloudy days.
