SlimFlexTW-2090 Nichia LED Strip Tunable white 2700-6500K 2140lm 24V 140 LEDs/m 2m reel (985+1070lm/m)

The SlimFlexTW-2090 is a very narrow professional tunable-white LED strip designed for architectural details where standard-width LED tape is difficult to install. At only 5 mm wide, it fits into slim profiles, furniture details, display elements and narrow coves while still providing two independently controllable white-light channels.

The 2 m reel uses 280 Nichia LEDs, equivalent to 140 LEDs per metre. Its compact construction, high CRI and adjustable white light make it especially useful where both space and light quality are important.

Tunable white for cove and indirect lighting

This product is particularly well suited to cove and indirect lighting, where the strip is hidden from direct view and the wall or ceiling becomes part of the lighting effect. Its 5 mm width is especially useful in narrow coves, shadow gaps and furniture details where a conventional 8–10 mm strip would be difficult to conceal.

With a suitable two-channel controller, the colour temperature and brightness can be adjusted to create different scenes from the same installation. Warmer white can support a softer evening atmosphere, while cooler white is useful for brighter, more task-oriented scenes.

Choosing the right white-light scene

Tunable white allows the installation to move between warmer and cooler white light without changing the luminaire. This is useful in residential, hospitality, retail, exhibition and workplace settings where the preferred appearance changes with the activity or time of day.

Ideal for compact furniture and display lighting

The narrow PCB makes the SlimFlexTW-2090 suitable for shelves, cabinets, display furniture and custom profiles where the lighting channel must remain visually discreet. The adjustable white light allows the same installation to move from a warmer presentation to a cooler, more neutral appearance without replacing the light source.

Control and installation

The strip is designed for 24 V DC operation and requires a compatible two-channel tunable-white controller so the warm and cool channels can be dimmed and mixed independently. The maximum recommended length per supply feed is 2 m, so longer continuous installations should be planned with additional power feeds.

The strip can be shortened every 100 mm at the designated cut points. The self-adhesive backing simplifies positioning on a clean, stable mounting surface. For longer runs, conductor sizing and feed-point placement should be planned to minimise voltage drop and keep the light consistent along the installation.

Our manufacturing and quality promise

We develop and manufacture professional LED strips and modules in Germany, combining more than 20 years of LED application experience with automated production and application engineering. Our focus is on repeatable performance, carefully selected components and products that can be integrated reliably into professional lighting systems.

For project customers, we can also support custom development, PCB adaptation, LED selection, thermal design, prototyping and series production. This allows the light engine to be matched to the luminaire or architectural application instead of forcing the project around a generic LED tape.
