Outdoor Christmas Lights

These are our Christmas lights for outside, the outdoor Christmas lights we supply across Ireland with free delivery on every order. Exterior Christmas lights for an Irish house need a stated outdoor rating, usually IP44, and a dry, weatherproof connection for every plug joint. Outdoor Christmas lights for Irish homes, from an independent Irish electrical supplier. Every light in this collection is rated for outdoor use, so it can go on a fence, a hedge, a gable wall or a garden tree and stand up to an Irish December. Free delivery applies to every order from the first euro, with no minimum spend. For help planning a display, read our outdoor Christmas lights buying guide.

Are these Christmas lights safe to use outdoors in Irish weather?

Yes. Every product in this collection carries an outdoor rating, which means it is built to handle rain, wind and cold without water reaching the electrics.

Irish winters are wet rather than especially cold, so water ingress matters more than temperature. Lights sold for indoor use only have no seal around the lamp holders or the joins, and moisture will eventually reach live parts. That is why we keep the outdoor rated products in their own collection rather than mixing them with indoor string and novelty lighting. If you are unsure about a set you already own, check the box or the plug label for an IP number. No IP number means indoor only.

What do IP44 and IP55 mean on outdoor Christmas lights?

IP44 means the light is protected against splashing water from any direction. IP55 adds protection against dust and against low pressure water jets.

For Christmas lights hung on a wall, a hedge or a tree, IP44 is the normal and appropriate rating and covers rain from any angle. IP55 is what you want for anything sitting at ground level, in a flower bed, or anywhere it could take standing water or spray. The rating covers the light itself, not the plug or the extension joint, which is a separate problem covered below.

Do I need a weatherproof box for outdoor Christmas lights?

Yes, for any connection made outdoors. The lights may be rated for outdoor use but the plug and socket join between them almost never is.

This is the single most common outdoor Christmas lighting fault we see. People run a correctly rated set of lights, then join it to an extension lead and leave the connection sitting on the grass or wedged behind a plant pot. A weatherproof connection box holds the join inside a sealed enclosure so rain cannot bridge the contacts. It is an inexpensive part and it is the difference between a display that lasts the season and a tripped RCD in the middle of December.

Can outdoor Christmas lights be connected together?

Many sets can, up to a stated maximum number. The limit is printed on the product and exists because each additional set adds load to the first plug.

Connectable sets use a coupler at each end so you can run one continuous line from a single socket. The maximum is typically three or four sets. Exceeding it overloads the first lead in the chain. If you need to cover a longer run than the maximum allows, take a second supply from a different socket rather than adding more sets to the same chain.

When should outdoor Christmas lights go up in Ireland?

Most Irish households put outdoor lights up in the last week of November or the first week of December, and take them down after Little Christmas on 6 January.

There is a practical argument for fitting the brackets and running the cable earlier, in milder weather, and simply not switching on until you are ready. Working at height on a wet ladder in December is the part worth avoiding. Plan the run and the power source before you buy, so you know how many sets and what length of lead you actually need.

What kind of Christmas lights are best for outside?

LED sets with a stated outdoor rating, like the IP44 icicle and string lights here, joined on couplers and powered through a dry, weatherproof connection.

The 5M 80 LED icicle lights are IP44 and draw 8.8W, with up to 12 sets connectable. The 120 LED string light is IP44, 12 metres long and draws 17.4W, with up to 6 sets connectable. For a focal point without a ladder, the LED lighted Christmas star sits on a ground spike and the pre lit LED Christmas tree is built for outdoor use. Our outdoor Christmas lights buying guide covers window lights, colours and safe power in more detail.

Can you use indoor Christmas lights outside?

No. Christmas lights for outside need a stated outdoor rating, such as IP44, on the box or the plug label. An indoor set has no seal against rain and belongs indoors only.

Even under a porch or a canopy, an indoor set picks up driving rain and condensation, and once water reaches a lamp holder it can trip the RCD and take out the whole circuit. The IP44 5M 80 LED icicle lights and the IP44 120 LED string light here both state their rating in their own listings. Whatever lights you use, keep every plug joint outside in a weatherproof enclosure such as the DRiBOX IP55 box.
