Frequently Asked Questions About Outdoor Christmas String Lights

Q1: What is the main difference between your ConnectGo® and ConnectPro® outdoor lighting systems?

A: The primary difference lies in scale and construction. ConnectGo® is a high-quality, low-voltage system ideal for domestic use, allowing runs of up to 100 metres from one plug. ConnectPro® is a premium, heavy-duty 240V system with thicker rubber cabling and superior IP65 weather-resistance, designed for large-scale, professional, and commercial installations, capable of running up to 950 metres from a single plug.

Q2: How do I know what length of outdoor string lights I need for my house or tree?

A: We recommend a density ratio for the best results. For sparse coverage on a fence or roofline, measure the linear distance and match the light length (e.g., a 10m run for a 10m roof). For a dense, 'wrapped' Christmas tree look, divide the tree's height (in metres) by its width (in metres), then multiply this ratio by 40 to get the approximate metres of lights needed.

Q3: Are your LED string lights expensive to run throughout the Christmas season?

A: No, our LED string lights are highly energy efficient. They use up to 90% less power than old-fashioned incandescent bulbs. For example, a long 100m run of our LED string lights might consume less energy than a single traditional light bulb, making them a very cost-effective choice for long festive displays.

Q4: Are the lights fully weatherproof and safe to leave outside in a UK winter?

A: Yes, all our outdoor lights are manufactured to be fully weatherproof, with high IP ratings (typically IP44, IP65 for ConnectPro®). This means they are protected against water ingress and can safely withstand typical British winter conditions, including rain, snow, and frost.

Q5: Can I connect lights from different brands or models to your ConnectGo® or ConnectPro® systems?

A: No, to ensure safety, reliability, and guaranteed weatherproofing, you must only connect lights within the same system. For example, ConnectGo® accessories and extensions are only compatible with other ConnectGo® sets, and they cannot be mixed with ConnectPro® or other brand lights.

Q6: Do your outdoor fairy lights come with a built-in timer function?

A: Many of our popular outdoor string light sets, especially those from the Festive Productions™ and Noma™ ranges, include a multifunction controller with a useful timer function (often 8 hours on/16 hours off). This feature automates your display, saving energy and providing peace of mind.

Q7: What is the estimated lifespan of your outdoor LED Christmas lights?

A: The LEDs in our string lights have a significantly long lifespan, typically rated for up to 50,000 hours of use. Under normal seasonal use (around 4-6 weeks per year), you can expect them to last for many years, making them a durable and sustainable investment.

Q8: What if a single bulb stops working on a long string of lights?

A: Our modern LED string lights are wired in a way that if one bulb fails, the rest of the set will remain lit. The single faulty bulb can often be replaced, but it will not cause the entire set to go out, ensuring your festive display remains intact.

Q9: Can I buy replacement power supplies or additional accessories like extension cables?

A: Yes, we stock a full range of accessories for both our ConnectGo® and ConnectPro® systems, including replacement power supplies, extension cables, splitters, and controller units. This makes maintaining, expanding, or modifying your existing display simple and straightforward.

Q10: What is your returns policy if the lights are not the right colour for my display?

A: We offer a comprehensive returns policy. If the colour (e.g., Warm White versus Cool White) or style isn't quite right, you can return the unused item in its original packaging within a specified period (please check our full T&Cs at checkout) for an exchange or refund.
