Frequently Asked Questions

Q: What makes this 270° channel different from other side-emitting channels?

A:This model features a unique dome top that creates an extra-wide 270° beam angle, providing a much broader and more immersive glow compared to standard 120° or 180° channels.

Q: Can I use COB LED strip lights in this channel?

A:Absolutely. This channel was specifically designed with a large internal space (up to 6mm high) to accommodate taller strips like COB, ensuring a perfectly smooth, dot-free neon effect.

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

A:This channel is designed for LED strip lights with a maximum PCB width of 12mm (0.5 inches).

Q: Is this channel suitable for outdoor use?

A:Yes, it has an IP67 waterproof rating. To ensure full protection, you must properly seal both ends with the included end caps and a suitable silicone sealant.

Q: Does this product include the LED strip?

A:No, this is a silicone channel/diffuser only. You will need to purchase a compatible 12mm LED strip light separately.

Q: How do I mount this silicone tube?

A:You can secure it using mounting clips, install it within a rigid aluminum channel for straight runs, or use it with flexible profiles for custom curved designs. The clip size is about 15mm*19mm.

Three Ways to Fix LED Neon Tube Lights

Q: What is the advantage of food-grade silicone?

A:Food-grade silicone is a high-purity material that offers excellent durability, heat resistance, and flexibility. It is also UV-resistant, meaning it won't yellow or crack when used outdoors over time.
