Does this product include the LED lights?

No, this is a flexible silicone diffuser tube only. You will need to purchase a compatible LED strip light separately.

What size LED strip fits inside this tube?

This diffuser is designed for any flexible LED strip with a Printed Circuit Board (PCB) width of up to 10mm (0.39 inches).

How do I make it waterproof for outdoor use?

To achieve an IP67 waterproof rating, you must seal both ends securely using the provided end caps and a quality RTV silicone sealant.

What is the difference between this side-emitting model and a top-emitting one?

This side-emitting model glows from the tall, 22mm face of the tube, creating a wide 180° beam. This is ideal for signs and lighting a surface next to the tube. Top-emitting models glow from the narrow, 9mm face.

Can I cut this silicone tube to a specific length?

Yes, the silicone tube is easily cuttable with a sharp utility knife. You can cut it to match the cutting increments of your chosen LED strip.

What are the benefits of food-grade silicone?

Food-grade silicone offers superior flexibility, a wider operating temperature range (-50°C to 200°C), and excellent resistance to UV radiation, which prevents it from yellowing or becoming brittle over time.

How to Create a Neon Light with this Silicone Diffuser

Attach a thin, strong string or wire to the end of the LED strip to act as a guide.
Feed the guide string through the silicone tube from one end to the other.
Gently pull the LED strip through the channel until it is fully inserted and lies flat.
Select the appropriate end caps (with or without wire holes) for each end.
Apply a bead of RTV silicone sealant to the inside of the end caps and press them firmly onto the tube ends for a secure, waterproof seal. Allow to cure.
Mount your new neon light using your chosen installation method: mounting clips installation, aluminum channel installation, or flexible profile installation.
