Curtain lights look simple until you start comparing them. One set is made for a small window, another is large enough to cover a feature wall. Some give you a fixed glow, while smart versions can display photos, GIFs, messages and animated effects. If you are comparing the best LED curtain lights in the UK, the useful differences are size, control, power, brightness, safety and what you actually want the display to do.
This guide explains those differences without assuming that the most expensive option is automatically the right one.
The short answer
- Choose the size by the space, not just the LED count. A smaller curtain suits a window or desk backdrop, while a larger one makes more sense for a bed wall or feature wall.
- Choose smart curtain lights if you want the display itself to change. A simpler set is enough if you only want a steady decorative glow.
- Check the power source before buying. USB powered lights need a compatible USB power source. Mains powered sets need a socket nearby.
- Check the IP rating and product instructions. An IP code tells you how the product is protected, but it does not replace the maker's guidance on where the lights can be used.
What are LED curtain lights?
LED curtain lights use vertical strands of LEDs hanging from a top cable or rail so the lights fall like a curtain. They can sit across a wall, in a window, behind a desk or behind a bed. Their main job is decorative lighting rather than replacing a ceiling light.
The biggest difference between products is how much control you get over the display. Basic sets usually focus on fixed colours or preset effects. Smart curtain lights can go much further by treating the curtain as a simple display that can change from one design to another.
Standard curtain lights or smart curtain lights?
This is one of the most important choices because it changes both the price and what the lights can actually do.
Standard curtain lights
Many standard sets focus on warm white, a fixed colour or a small group of preset effects. They work well when you want a simple decorative backdrop for a bedroom, window or seasonal display and do not need to upload your own content.
Smart curtain lights
Smart versions add app control and can turn the curtain into a changeable display. Depending on the product, that can include custom images, GIFs, text, drawings, music effects, brightness controls and schedules.
If you want one calm look and rarely plan to change it, a standard set may be enough. If you want the same lights to change for gaming, birthdays, Halloween, Christmas or parties, smart control is much more useful.
How big should LED curtain lights be?
Measure the width and height of the space before comparing products. The physical size matters more than the headline LED count because the curtain still needs to fit the wall, window or backdrop you have in mind.
| Space | Sensible size | Why |
|---|---|---|
| Small window or desk backdrop | 1 × 1m | Compact coverage without overwhelming the space |
| Standard window or part of a wall | 2 × 2m | A balanced option for medium sized spaces |
| Bed wall, feature wall or large backdrop | 3 × 3m | The largest display area of the three |
LED count still matters, but it should be read alongside size. Zyko's current curtain lights use 400 LEDs on all three sizes. That means the 1 × 1m version places the same number of light points into a smaller area, while the 3 × 3m version spreads those points across a much larger display. The smaller size will therefore look denser when displaying artwork or text.
Power, safety and IP ratings
Power and safety information is easy to skim past on a product page, but it matters more than a long list of lighting effects.
Check how the lights are powered
USB powered sets need a compatible USB power source. Battery powered sets can be useful when a socket is not nearby, but battery life will depend on the product, brightness and effects being used. Mains powered decorative lights sold for UK use should use the correct UK plug and fuse.
Electrical Safety First recommends buying decorative lights from a reputable retailer, checking the rated voltage and following the manufacturer's instructions. It also says that extra low voltage decorative lights are the safer option because a suitable transformer reduces the risk of electric shock.
Read the IP rating properly
IP stands for Ingress Protection. The first digit relates to protection from solid objects and the second to water. An IP44 rating indicates protection from objects larger than 1mm and splashing water from different directions.
That does not mean every IP44 curtain light should be left exposed outdoors in any weather. Check the product instructions for where the full set can be used, and keep plugs, power connections and controllers protected as directed by the manufacturer. Electrical Safety First also advises that plugs and transformers stay indoors even when decorative lights themselves are suitable for outdoor use.
Simple safety habits
- Inspect the cable and connections before use.
- Keep decorative lights away from flammable materials.
- Do not connect separate sets together unless the manufacturer says this is supported.
- Switch the lights off when they are not in use and follow the product instructions.
What to look for before you buy
- Real dimensions. Look for the width and height in metres rather than vague descriptions such as small or large.
- Power source and voltage. Know whether the set uses USB, batteries or mains power and what you need to run it.
- IP rating. Check this if the lights may be used near moisture, then follow the product's specific placement guidance.
- Controls you will actually use. Image upload, timers, brightness, music effects and drawing tools can be useful, but only if they fit how you plan to use the lights.
- Delivery and returns. Check the expected delivery window and how long you have to return an eligible item.
- Support. A clear contact route matters if something arrives damaged or stops working.
A buyer's example: Zyko Smart LED Curtain Lights
Zyko currently sells one smart curtain light range in three sizes. It is useful as a real example of how the checks above come together without pretending that one product is right for everyone.
Sizes and standard prices
| Size | LED count | Standard price |
|---|---|---|
| 1 × 1m | 400 LEDs | £49.99 |
| 2 × 2m | 400 LEDs | £59.99 |
| 3 × 3m | 400 LEDs | £69.99 |
These are the standard reference prices for each size, so the guide does not depend on a temporary sale price. The current product page may show promotional pricing separately.
What the Zyko set includes
Every size uses 400 LEDs. The current listing states USB power, an input voltage of up to 36V, adjustable brightness and an IP44 rated design. Control is through a smartphone app.
The app supports custom photos and GIFs, custom messages, drawing your own designs, music reactive effects, timers and schedules. That makes the set better suited to someone who wants a display that can change rather than a single fixed lighting effect.
The product page currently quotes free worldwide delivery, most orders arriving within 6 to 12 business days, and eligible returns within 30 days of delivery.

Who it suits
The set makes most sense for gaming setups, streaming backgrounds, bedrooms, parties and seasonal displays where changing the design is part of the appeal. If you only want a plain warm white glow with no interest in app control or custom content, a simpler curtain light set may be the better buy.
If you are planning a setup around custom artwork, our pixel display comparison looks at another way to display images and designs. For tighter spaces, our small gaming room ideas guide can help with layout decisions.
Frequently asked questions
Are LED curtain lights safe?
They can be a low risk decorative product when bought from a reputable retailer and used according to the instructions. Check the rated voltage, inspect the cable and connections before use, keep them away from flammable materials and switch them off when they are not in use.
Can you cut LED curtain lights?
Do not cut a curtain light set unless the manufacturer specifically says it is designed for that. The safer approach is to choose the size that fits the space.
What size curtain lights do I need?
Measure the width and height of the area first. A 1 × 1m set suits smaller windows and desk backdrops, 2 × 2m works for medium sized wall or window coverage, and 3 × 3m is better suited to large feature walls and backdrops.
Are LED curtain lights good for a bedroom?
Yes, as decorative or ambient lighting. Brightness control and scheduling are useful if you want the display to feel less intense in the evening or switch off automatically later on.
Can curtain lights be used outside?
Only use a set outdoors where the manufacturer says it is suitable. An IP44 rating provides splash protection, but plugs, controllers and power connections still need the protection specified by the maker. Do not assume that an IP rating alone makes the whole set suitable for exposed weather.
Do smart curtain lights work without the app?
It depends on the product. If using the lights without a phone matters to you, check the control method before buying. Zyko's current listing describes smartphone app control for designs, brightness, effects and schedules, so app control should be treated as the main way to access those features.
The bottom line
Start with your measurements, then decide whether you want a simple decorative glow or a display you can keep changing. After that, check power, brightness, IP rating, delivery and returns before you pay.
