To diffuse LED light strips, you can use a variety of materials to soften the appearance of the light and reduce harsh shadows. Some options include frosted tape or film, a diffuser panel, a lampshade, a lightbox, or sheer fabric.
You can also try using “double diffusion,” or adding an additional layer of diffuser material between the LED light strip and the first layer of the diffuser, to create an even softer, more diffuse light.
These methods can help you create a softer, more comfortable lighting environment in your home.
Why people diffuse LED lights and strip lights:

- To reduce harsh shadows: LED lights can create harsh shadows, especially when they are used in task lighting or accent lighting. Diffusing the light can help to soften the shadows and create a more even, comfortable light.
- To create a softer, more even light: Diffusing LED lights can create a softer, more even light that is less harsh and more comfortable to look at. This can be especially useful in spaces where you want to create a warm and welcoming atmosphere, such as a living room or bedroom.
- To add interest to a space: Diffusing LED lights can add visual interest to a space by creating a more dynamic and layered lighting effect.
- To hide the source of the light: Diffusing LED lights can help to hide the source of the light, which can be especially useful if you don’t want the light fixtures themselves to be the focus of the room.
- To protect the eyes: LED lights can be very bright and harsh, especially if they are not diffused. Diffusing the light can help to protect the eyes from glare and reduce eye strain.
There are a few ways you can diffuse LED light strips to soften the appearance of the light and reduce harsh shadows. Here are a few options you can try:
Use frosted tape or film: You can apply frosted tape or film to the LED light strip to diffuse the light. This will create a softer, more even light.
Use a diffuser: There are diffuser panels or sheets that you can attach to the LED light strip to diffuse the light. These can be made of acrylic, plastic, or other materials.
Use a lampshade: If you’re using LED light strips to provide task lighting or accent lighting, you can use a lampshade to diffuse the light.
Use a lightbox: A lightbox is a box that has a translucent surface, such as frosted acrylic or plastic. You can place the LED light strip inside the box, and the light will be diffused as it passes through the surface of the box.
Use a sheer fabric: You can hang a sheer fabric, such as a white or off-white sheer curtain, in front of the LED light strip to diffuse the light. This will create a softer, more diffuse light that is less harsh and more comfortable to look at.
Diffusing by using Buffers
Yes, using buffers or “double diffusion” is another way to diffuse LED light strips.
By adding an additional layer of diffuser material between the LED light strip and the first layer of the diffuser, you can create an even softer, more diffuse light.
This can be especially useful if you find that the light from the LED strip is still too bright or harsh after using a single layer of the diffuser.
You can use any of the materials mentioned in the previous answer, such as frosted tape or film, a diffuser panel, or a lampshade, as a buffer to create this double diffusion effect.
Few fun DIY ways to diffuse LED light strips:
Use paper lanterns:

You can place LED light strips inside paper lanterns to create soft, diffuse light. This is a simple and inexpensive way to add a decorative touch to your lighting.
Use mason jars:

You can place LED light strips inside mason jars to create a rustic, vintage-inspired look. You can use frosted tape or film to diffuse the light even more.
Use tin cans:

You can repurpose tin cans, such as soup cans or coffee cans, as diffusers for LED light strips. Simply cut a hole in the bottom of the can and run the LED strip through it. The light will be diffused as it passes through the metal of the can.
Use recycled bottles:

You can cut the bottoms off of recycled bottles, such as wine bottles or beer bottles, and use them as diffusers for LED light strips. This is a fun and eco-friendly way to add some personality to your lighting.
Use a shoebox:
You can create a simple light box by cutting holes in a shoebox and placing an LED light strip inside. This is a fun and easy way to diffuse LED light strips for a DIY project.
FAQ
What is a diffuse light source?
A diffuse light source is a light source that emits light in all directions, rather than in a specific direction. This creates a softer, more even light that is less harsh and creates fewer shadows.
What is the main difference between clear and diffused LED strips?
The main difference between clear and diffused LED strips is the way the light is emitted. Clear LED strips emit light directly, while diffused LED strips emit light in all directions, creating a softer, more even light.
What is a light diffuser?
A light diffuser is a material that is used to diffuse light, creating a softer, more even light. Light diffusers can be made of a variety of materials, such as frosted glass, plastic, or fabric.
Can I cover an LED light strip?
Yes, you can cover an LED light strip with a diffuser material to soften the light and reduce harsh shadows. This can be done using frosted tape or film, a diffuser panel, a lampshade, or a lightbox.
