What is the main advantage of this 270° diffuser?

Its primary benefit is the double side emitting design, which provides a much wider and more immersive light output than typical 120° or 180° top-emitting or side-emitting neon diffusers.

What kind of LED strip can I use with this diffuser?

You can use any flexible LED strip with a PCB width of 10mm or less. This includes our single color led strip, CCT, RGB, RGBW, and addressable strip lights.

Can I cut this silicone tube to a custom length?

Yes, the silicone diffuser is designed to be cut easily with sharp scissors or a utility knife at any point along its length to fit your project's exact requirements.

How does the free assembly service work?

When you purchase this silicone diffuser and any of our compatible 10mm LED strips in the same order, our technicians will insert the strip, solder a lead wire, and seal the ends for you, delivering a ready-to-install neon light.

Is this product suitable for outdoor use?

Absolutely. It is made from UV-resistant silicone and achieves an IP67 waterproof rating when the end caps are properly sealed with silicone adhesive, making it perfect for outdoor applications.

What are the available mounting options?

You can install it using dedicated mounting clips, press it into a rigid aluminum channel for perfectly straight lines, or use it with flexible profiles for creating precise curves.
