Svater Outdoor Festoon Lights Mains Powered (25ft) with 13 G40 E12 LED Bulbs – IP45 waterproof, connectable up to 20 strings
Product description
Looking for garden string lights that are actually easy to set up outdoors and don’t guzzle power? Svater’s mains powered festoon lights come as a 25ft strand with 13 LED G40 plastic bulbs, built for patio, backyard and party use where you want a warm, festive look without the fuss of constantly replacing bulbs.
That said, there are a couple of real-world limits worth noting: the dimmer is not included, and while the set is connectable, your final layout will still depend on where you can run the mains connection.
The essentials
These are outdoor festoon style string lights designed to plug into the mains. They include 13 G40 LED bulbs and use E12 bulbs, with 12 feet of E12 socket spacing mentioned in the product details and a total length of 25ft. The bulbs are made from plastic, and the strand is IP45 waterproof, which is a key point if you’re hanging lights outside and don’t want to baby them every time the weather turns.
There’s also a practical benefit in the way the lights are wired: they’re connected in parallel. So if one LED filament breaks or is removed, the remaining LED filaments should stay lit. On paper, that’s the kind of small design detail that makes maintenance easier.

What matters most for outdoor use
Outdoor string lights are mostly about “will they cope?” and “will they be easy to live with?” Here, the manufacturer positions the strand as resistant to water and the elements, and gives it an IP45 rating. It also includes clips on the side of each bulb, intended to help you clip onto branches or secure with a nail.
A micro example: imagine you’re stringing lights along a garden pergola. You can clip each bulb to the support using the side clip, move along the run in a straight line, and only later tidy spacing—if one bulb needs adjustment, it shouldn’t take the whole run out.
One limitation to consider: IP45 is helpful for typical outdoor conditions, but it’s still wise to think about how exposed your setup is (for example, if it’s in the direct path of heavy rain or water jets, you may want to use more protection and secure fixing points).


Quick overview of performance and savings

The bulbs are described as LED G40s designed to save more than 90% energy compared with incandescent bulbs. That matters if you plan to leave them on for evenings through the warmer months.
The claimed lifespan is up to 30,000 hours, which—assuming they’re used in sensible outdoor conditions—can reduce replacement frequency. If you’ve ever had to swap festoon bulbs mid-season, you’ll appreciate how this shifts the stress from “maintenance” to “setup once”.
Connectable festoon lights for custom layouts
A standout feature is that the strand is described as connectable from one end to the other, with the ability to connect up to 20 strings. If you’re building a longer run for a party or filling a wider patio, that flexibility can be more valuable than buying a single, awkwardly long set.
What you’ll want to check in your space is the distance between anchor points and where your mains outlet is. Even if you can connect many strands, you still need practical cable routing, and you don’t want to end up with sagging or too-tight spacing because the power feed limits your placement.

Dimming and controls: small detail, big impact
The product is described as “dimmable”, but it also says a dimmer is not included. So if you want adjustable brightness, you’ll need to plan for the missing dimmer separately.
It’s a sensible arrangement for buyers who already have compatible outdoor dimming equipment, but it can feel incomplete if you were expecting a full “plug in and tweak brightness” kit.

Who it suits (and who should look elsewhere)
It’s a good fit if you’re planning outdoor patio, backyard or party lighting and you want mains powered convenience, included LED bulbs, and a set that’s built for being installed outdoors with an IP45 waterproof rating. The parallel connection design is also a plus if you’d rather not have one failed bulb ruin the whole visual line.
It might not suit you as well if you expected the dimmer to be included, or if your installation requires fully weatherproof protection beyond IP45 in very harsh conditions. Also, because it’s mains powered, it’s less flexible than battery or solar options if you don’t have a nearby outdoor outlet.
Final verdict
Worth considering if you want plug-in outdoor festoon lights with included E12 LED G40 bulbs, connectability for custom runs, and an IP45 waterproof focus for everyday garden use. It’s best thought of as a practical, mid-range style outdoor lighting solution where setup ease and lower running/maintenance hassle matter.

You may want to skip it if you need a complete dimming kit in the box, or if your space makes mains routing awkward. In that case, a different power setup approach could save you effort.
