Tunable white for professional linear luminaires

The 2700–6500 K range allows one luminaire to move from warm ambience to daylight-white task lighting. This is useful in offices, healthcare, education, hospitality and multi-purpose spaces where the visual atmosphere changes during the day.

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.

Troffers and diffuse commercial luminaires

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.

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.

Two-channel constant-current driver integration

Each channel operates at 144 mA and approximately 37.2 V. Use a two-channel tunable-white constant-current driver or two coordinated regulated current channels; do not connect the module directly to a constant-voltage supply.

If several modules are combined, keep warm and cool channels electrically separated and design the series or parallel architecture around the driver voltage window and validated current sharing.

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.
