What is the maximum width of the LED strip I can use?

This diffuser is designed for LED strips with a PCB width up to 10mm. It is also suitable for narrower strips, such as 8mm.

Is this a complete, ready-to-use light?

No, this is a silicone diffuser tube only. You need to purchase LED strips and a compatible power supply separately to create a functional light.

How do I mount this neon tube?

You can purchase the kit that includes mounting clips, which can be screwed onto a surface to hold the tube securely in place.

Is it difficult to insert the LED strip?

For longer lengths, it can be helpful to use a pulling string and a silicone-safe lubricant. For your convenience, if you purchase compatible LED strips from us in the same order, we offer a free assembly service.

This unique Φ22mm diffuser transforms standard 10mm LED strips such as our addressable COB strips into a continuous, perfectly round neon light. Unlike typical neon channels that have limited viewing angles, this tube provides seamless, all-around illumination, perfect for creating floating light installations and dynamic art pieces.

Crafted from durable, food-grade black silicone, it offers a sleek, modern aesthetic that appears as a discrete black rod when off and erupts with vibrant, dot-free color when lit. Its IP67 waterproof and UV-resistant construction makes it ideal for both indoor and outdoor architectural lighting, custom signage, and landscape design.

Frequently Asked Questions

Q: Do I need one or two LED strips for this tube?

A:To achieve the full 360-degree glow, you must install two LED strips back-to-back inside the tube. A single strip will only illuminate approximately 180 degrees.

Q: Does the black tube affect the light color?

A:The black silicone provides a sleek, non-luminous look when off. When lit, it diffuses the light from your LED strip, creating a vibrant, uniform glow. The perceived color will be true to your LED strip's output.
