Buyer's tips
- Indoor vs outdoor matters. Indoor-only sets are not weatherproof; outdoor-rated sets cost a little more but are safe in rain.
- Count the LEDs and length. A 6ft tree wants around 300–400 LEDs; bigger trees more. Check the cable length reaches a socket.
- Warm or cool white? Warm white is the classic cosy choice; cool white is crisper and more modern.
- When to buy. Order in October before stock thins; the biggest savings land in our Christmas Deals UK 2026 hub through late November and early December.
FAQ
How many lights do I need for a Christmas tree? A rough guide is 100 LEDs per foot of tree — so a 6ft tree wants around 600 LEDs for a full, bright look.
Can indoor Christmas lights be used outside? Only if they're marked for outdoor use. Indoor-only sets aren't weatherproof and can be dangerous in rain.
Are smart Christmas lights worth it? For a single feature tree, yes — the Twinkly app lets you map animations that ordinary lights simply can't do. For everyday string lights, a simple timer set is plenty.
