Questions before you decorate?
Find the right lights for your space, understand how connectable sets work and plan a display you’ll enjoy throughout the season.
Can indoor Christmas lights be used outdoors?
Only use lights outside when the product is specifically described as suitable for outdoor use. Check the rating of the lights, power supply and battery box where applicable. Indoor-only lights should stay inside. Browse our outdoor Christmas lights for exterior displays.
How many Christmas lights do I need for my tree?
Start with the tree’s height and the look you want. A light scattering needs less length than a tree wrapped through its branches. Compare each set’s lit length, rather than its total cable length, and allow extra length for fuller coverage. For a larger tree, consider compatible connectable lights .
Can I connect different Christmas light sets together?
Only connect sets confirmed as compatible within the same system. Check the connector, operating voltage, required power lead or transformer, and the maximum number of sets allowed. Never connect a low-voltage set directly to a mains-voltage set. If you are unsure, check the product details or ask our team before ordering.
Which lights work best for trees, windows and rooflines?
String and cluster lights work well around Christmas trees and greenery. Curtain lights create a backdrop across a window or wall, while icicle lights produce a hanging effect along an eave or entrance. For an outdoor location, choose a product specifically rated for exterior use. Explore the full Christmas lights collection to compare styles.
Can battery-operated Christmas lights be used outside?
Some can, but check the individual product description. Both the light set and its battery compartment must be suitable for the intended location. Battery lights are also useful for indoor wreaths, garlands and table displays where a nearby socket would be inconvenient. See our battery-powered lights .
How much electricity do LED Christmas lights use?
It depends on the product’s wattage and how long it runs. Divide the wattage by 1,000, then multiply by the hours used to calculate kilowatt-hours (kWh). For example, a 10W set used for five hours a day over 30 days uses 1.5 kWh. Multiply that figure by your electricity rate to estimate the cost, or use our energy calculator .
Can you help plan a larger or commercial Christmas display?
Yes. Tell us where the display will go, the approximate dimensions and the effect you want to create. Our team can help you compare suitable lighting systems and decorations for a larger home, business or public-space project.
