LumiBarTW-26-4090 Nichia 2 in 1 Series LED Module 2700K-6500K Tunable White CRI80 1081lm 28cm module

The LumiBarTW-26-4090 is a compact tunable-white rigid module built around Nichia 2-in-1 LEDs. Warm and cool emitters are combined under one light-emitting surface, helping the luminaire achieve smoother colour mixing than a conventional alternating warm/cool LED layout.

Compact tunable-white luminaire design

The 2-in-1 LED architecture is particularly useful in shallow luminaires because warm and cool light are mixed inside each LED package rather than from separately spaced LEDs. This reduces the optical distance needed to obtain a visually homogeneous white-light transition.

Rigid light engine for professional linear luminaires

The rigid PCB is designed for linear luminaires, continuous light lines and compact commercial fixtures where a straight, mechanically stable LED board is preferable to flexible tape. The defined LED pitch helps create a smooth luminous line behind a suitable diffuser, while the rigid module simplifies repeatable positioning inside an OEM luminaire.

For guidance on profile depth, diffuser distance and LED spacing, see our linear fixture design guide.

The module is also suitable for troffers and diffuse ceiling luminaires. Multiple modules can be arranged in rows behind a diffuser to create a broad luminous surface for offices, classrooms, healthcare spaces, retail and other commercial interiors. Final spacing should be selected according to the diffuser, optical distance and required luminance uniformity.

Cove and architectural white-light control

The 2700–6500 K range also suits cove and indirect lighting where one concealed installation needs to cover both warm ambience and cool functional scenes.

Built around the Zhaga Book 7 linear-module standard

This module is designed around the Zhaga Book 7 L28W2 linear-module form factor. The L28W2 category gives the luminaire designer a recognized mechanical envelope and keep-out area for this class of linear LED module. This can simplify mechanical design, sourcing, servicing and later product revisions when a luminaire family is built around standardized module dimensions.

Zhaga Book 7 supports mechanical interoperability, but it does not make the electrical operating point, luminous flux, efficiency or optical performance identical between modules from different manufacturers. The LED driver current, forward-voltage range, connector arrangement, thermal conditions and photometric performance must therefore still be checked for the specific module and luminaire.

Book 7 has also been published as IEC 63356-2. The modules require a separate LED driver and are intended for professional luminaire integration and servicing.

Constant-current tunable-white integration

The warm and cool channels require a compatible constant-current control architecture. The driver and controller must be selected for the electrical operating point of the module rather than treating it as a conventional 24 V tunable-white strip.

Designed and manufactured in Germany

We develop and manufacture professional rigid LED modules and flexible LED light engines in Germany, combining more than 20 years of LED application experience with controlled SMT production and application engineering. Our focus is on predictable optical performance, specified LED components, repeatable electrical characteristics and light engines that can be integrated reliably into professional luminaires.

For OEM and project customers, we can also support LED selection, PCB adaptation, thermal design, prototyping, optical evaluation and series production. This allows the light engine to be matched to the luminaire and application instead of forcing the project around a generic LED board.
