Animated Christmas Window Lights

Christmas window lights that do more than twinkle. Lumalyn hangs inside your window like a curtain and plays animated Christmas pictures, messages and patterns that neighbors can see from the street, while it stays warm and dry indoors.

Indoor Christmas window lights you can see from outside

Most indoor window lights look great from the sofa and disappear from the street. Lumalyn is a window curtain light made of thin clear strands carrying 400 individually controlled RGB LEDs. Hung close to the glass, the strands form a bright low-resolution screen, so a waving Santa, a snowman or a "Merry Christmas" message is easy to read from across the road.

  • App + remote control – change designs, colors and brightness in seconds
  • Timers – the window lights up at dusk and switches off at bedtime

Which size fits my window?

Size Best for
2 × 2 m (6 ft 7 in) Standard windows and bay-window panels
3 × 3 m (9 ft 10 in) Patio doors, French doors and wide picture windows

Pick the size closest to your window width: curtain lights look best hanging straight, not bunched up.

How to hang Christmas lights in a window

  1. Clip the top wire to your curtain rail or to clear adhesive hooks along the top of the frame.
  2. Let the strands drop straight and keep them a few centimeters (about an inch) from the glass.
  3. Plug the USB controller into a USB wall adapter (not included) and pick a design in the app.
  4. Close the curtains or blinds behind the lights. A dark background makes the picture pop.

Frequently asked questions

Can I use these Christmas lights inside a window?

Yes. Lumalyn is ideal indoors behind the glass: it is safe, dry and still clearly visible from outside at night.

Do the lights work in the US, UK and Europe?

Yes. They run on 5 V USB power, so they work anywhere with a USB wall adapter for your local plug. The adapter is not included.

Will the lights reflect inside the room?

Keep the strands close to the glass and lower the brightness to around 50–70% at night to reduce reflections.
