As the sparkling centrepiece of your home at Christmas, it’s only natural you want your tree to look its absolute best. So there’s nothing more frustrating than decorating it—only to realise the lights are too short or there aren’t enough bulbs. Fortunately, we’re here to help. In this blog, we’ll show you exactly how many lights you need to give your 5ft, 6ft, 7ft, or 8ft tree the perfect festive glow.
Choosing a Christmas Light Length
At Christow, we stock a range of LED string lights that are perfect for adding festive sparkle to both real and artificial Christmas trees. Each set includes flashing light modes and a handy timer function to light up automatically each night. Plus, they’re energy-efficient and low-cost to run—so you can keep the magic going without breaking the bank.
When it comes to choosing the right length, it’s all down to personal preference. Fewer lights give a softer, more natural glow, while extra lights create a bolder, more dazzling display. Our recommendations aim for the sweet spot—just the right amount of sparkle for a perfectly balanced festive look.
LED Christmas Tree Lights
Working out how many lights you need is easy with our LED Christmas Tree Lights because they're tailormade to the perfect length. The 3mm micro LEDs are smaller than standard 5mm bulbs, so they blend beautifully with your branches for a more seamless look. With 2.5cm spacing between each light, they deliver a bright, even glow—perfect for a showstopping festive display.

What Colour Christmas Lights Should You Choose?
Now that you know how many lights your tree needs, it’s time to pick a colour. At Christow, our lights come in warm white, white, mixed white, and multi-coloured to suit every festive theme and personal style.
Warm White Lights
The timeless choice. Warm white LEDs are ideal for traditional Christmas trees, casting a soft, golden glow that creates a cosy, welcoming feel in any room.
White Lights
Cool, clean, and modern. White LEDs are brighter than warm white and perfect for contemporary spaces. They also pair beautifully with darker baubles and décor.
Mixed White Lights
Can’t decide between warm or cool white? Enjoy the best of both worlds. Mixed white lights combine warm and cool white LEDs to create a beautifully balanced glow—ideal for both classic and modern styles.
Multi-Coloured Lights
Fun and festive. With vibrant red, green, blue, and orange LEDs, multi-coloured lights are perfect if you want your Christmas tree to stand out and make a cheerful statement.
What About Baubles and Decorations?
Always decorate after adding your lights. Hanging baubles first only leads to chaos—and broken glass, à la Home Alone. Save the drama for the movies and not your Christmas tree.
Decorating your tree is also a chance to show off your personality. Whether you love traditional trinkets or fancy a Taylor Swift bauble or John McClane tree topper, it's your tree, your rules.
- Start with a mix of matte, shiny, and sparkly baubles in your base colour.
- Add complementary tones—gold with red, silver with white, blue with icy hues.
- Layer in statement pieces, like a glittery Santa or a sparkly sausage dog.
- Try a theme, such as a woodland wonderland or enchanting Frozen look.
- Step back, assess your tree, and shuffle things around if it looks bare in places.
- And don’t forget a topper—star, fairy, or a festive favourite like a fluffy sprout.
We love pairing trees with our light-up parcel decorations. Sold in sets of three, they come in a range of colours and styles, beautifully lit by warm white LEDs to add a cosy glow beneath your tree.
Launched in 2024, our LED Christmas Tree Mats are lit by 80 warm white LEDs to add a festive glow beneath your tree stand. Perfect for turning your festive centrepiece from lovely to wow.
Now all that's left is to pour a glass of Buck's Fizz and admire your festive masterpiece.
