Give the Room
Its Own Signature.
Design inspiration for reception desks, hotel rooms, bars, restaurants, homes, corridors and feature walls. Illustrative applications; specify each installation individually for every distinctive lighting project.
Let Your Design
Take a Turn.
Sweep around a feature. Follow a wall. Trace a gentle arch. Flexible silicone opens up forms that rigid profiles cannot follow.
depending on orientation
Plan broad curves and avoid twisting or sharp folds. Confirm the bending limits before routing a curved channel throughout the entire planned installation.

A Considered Installation.

-
Prepare the channel
Route your surface to the chosen profile’s drawing, allowing for any heat sink. Keep the channel clean and free of dust.
-
Plan for heat
Use a suitable aluminium heat sink where required by your LED strip and diffuser. The 10 × 10mm profile guidance recommends one above 10W/m; check the requirement for your chosen model.
-
Fit the LED strip
Adhere a compatible LED strip to the prepared base or heat sink. For curved runs, consider SideWinder bendable LED tape.
-
Press in the diffuser
Cut the silicone cover to length and press it over the strip. The ribbed sides grip the channel, holding the diffuser in place for a flush finish.
A Flexible Diffuser.
Meet Its Perfect Partner.
SideWinder bendable LED strips follow intricate shapes and corners, with bends up to 90°. An adhesive backing makes fitting straightforward.

The Finer
Details.
A little planning makes all the difference. Start with the profile, then build the lighting system around it from the very beginning.
View All Silicone ProfilesIs this a complete LED light?add
These products are silicone diffusers for LED strips. Plan the diffuser, compatible LED strip, power supply and any controls as a complete system. Choose your profile first, then check its product page for strip compatibility and installation Details.
How do I achieve a dot-free finish?add
The opal silicone blends the LED output into a continuous line. Pair it with a suitable COB tape or a high-density strip with at least 120 LEDs per metre, and check the strip fits the chosen profile. The finished effect also depends on the LED-to-diffuser spacing and your installation.
Which profile should I choose?add
Choose a standard 20 × 20mm trimless profile for a minimal flush edge. A winged 20 × 20mm profile has a top flange that overlaps the routed edge. Specialty sizes include 10 × 10mm, 12 × 12mm, 16 × 16mm and 30 × 20mm. Compare all nine profiles and check the dimensional drawing before routing.
Can the diffuser bend around a corner?add
Use gentle curves, with up/down or left/right bending according to the profile orientation. Bend on one axis at a time; do not force sharp corners or twist the profile. Check the selected product’s bending guidance before setting out the channel. For a curved LED run, explore SideWinder bendable LED strips for smooth directional illumination.
Do I need an aluminium heat sink?add
Higher-power LED strips need appropriate heat management. The 10 × 10mm diffuser product page recommends an aluminium heat sink above 10W per metre. Check the chosen diffuser and strip specifications for the correct requirement, and allow for the heat sink when planning the channel.
Is it suitable for splash-prone areas?add
The silicone diffuser is described as IP65 splashproof. This does not establish the rating of the complete lighting installation: the LED strip, connections and sealing must suit the intended location. SideWinder strips are IP20, so they should not be treated as a waterproof lighting system.
Can I cut the roll to the length I need?add
Yes. The diffusers are available in 5 metre and 50 metre rolls and can be cut to the required length. Cut the LED strip only at its specified cutting points and follow the installation instructions for both components.
