XH4025 vs. T4025 vs. YT4025

We offer three models of large, flexible silicone LED diffuser tubes with the same 40×25 mm dimensions. While their internal structures differ, their overall functionality is identical. If you’re unsure which one to choose, you can purchase a one-meter sample of each to test and determine which best suits your project’s needs.

Technical Highlights

  • The 23mm internal width is specifically engineered to accommodate high-power, multi-row, or wide LED strips such as SMD2835 and addressable pixels (up to 20mm), which are often used in projects requiring maximum brightness.
  • The high-quality silicone material eliminates hotspots, providing a completely uniform, seamless neon glow.
  • When properly sealed with end caps and silicone adhesive, the sleeve protects the internal LED strip from dust and water.
