ConextBar4 LED Module Warm White 2700K CRI90, 4 Nichia LEDs, 64 lm, 24 V, 2.07 cm
The ConextBar4 is a 20.7 mm long, 10 mm narrow LED module with 4 warm white 2700K Nichia 757 series LEDs and a color rendering index above 90, delivering 64 lm at about 0.48 W. With the patented Conext puzzle connection, ConextBar modules plug together into LED bars of variable length, without tools, solder or cables, and run on 24 V constant voltage. At only about 2 cm, the ConextBar4 lets you adjust the length of a ConextBar line in fine steps.

Applications of the ConextBar4
With the Conext system, the ConextBar4 is used for the following main applications:
- Signage and illuminated shapes: Letters, logos, symbols and pictograms can be built directly from ConextBar4 modules, without a separate PCB layout, and placed behind a diffuser or in an illuminated sign. More about LED modules for signage backlighting.
- Light lines and designer luminaires: LED bars of exactly the required length for luminaires, light bodies and shelf lighting, combining 10.4 cm and 2.07 cm modules.
- Showcases and detail lighting: The slim 10 mm wide modules fit into narrow profiles and display cases and bring warm, high-CRI light to merchandise and details.
- Warm white light: Nichia LEDs provide warm white light for a cozy, inviting atmosphere. The 2700K color temperature gives a cozy, intimate warm white light. Find out which color temperature suits your project in our guide Choosing the right color temperature for LED lighting.
The Conext Connection System: LED Modules That Connect Like Puzzle Pieces
With the patented Conext connection system, LED modules are plugged together like pieces of a puzzle and are electrically connected at the same time: electrical contacts on the noses and in the matching indentations conduct the current reliably from module to module. No soldering, no cables and no plugs are needed, and the modules lie flat without any additional connectors, so they fit into very slim designs. Anyone who has ever done a puzzle can assemble a Conext light shape, without tools or technical knowledge.
ConextBar modules run on 24 V constant voltage and form LED bars of variable length from four parts: the 10.4 cm ConextBar20 module with 20 LEDs, the 2.07 cm ConextBar4 module with 4 LEDs for fine length adjustment, and two power supply modules (a female module with mouth and a male module with nose) with connection terminals. One supply module feeds up to 50 ConextBar20 or 250 ConextBar4 modules.
Modules connect within their own series: ConextPlay runs on 5 V, while ConextMatrix and ConextBar run on 24 V.
Technical Data of the ConextBar4
- Article number (SKU): 32127
- LED: Nichia 757 series
- Number of LEDs: 4
- Light color: Warm white, 2700K
- Color rendering index: CRI (Ra) >90
- Luminous flux: 64 lm
- Power: about 0.48 W (calculated)
- Efficacy: about 133 lm/W (calculated)
- Operating voltage: 24 V DC constant voltage
- Dimensions: 20.7 x 10 x 2.33 mm
Installation and Operation
- Assembly: plug the modules together on a flat surface until the noses sit fully in the indentations; only completely engaged contacts conduct the current reliably.
- Mounting: fix the assembled shape on a flat, non-conductive surface and make sure that no metal parts bridge the contacts.
- Power supply: connect the terminals of a ConextBar power supply module to a stabilized 24 V DC constant voltage LED driver, sized for the total load plus a safety margin. One supply module feeds up to 50 ConextBar20 or 250 ConextBar4 modules (about 120 W, calculated); for longer runs, use several supply modules.
- Handling: do not touch or press the LEDs, observe standard ESD precautions, and use the modules only indoors in dry environments.
Why the ConextBar4 Outperforms Low-Cost LED Modules
Compared with low-cost LED modules, the ConextBar4 differs in two areas that decide how long a lighting installation performs well:
- LED quality: we use only brand-name LEDs from Nichia, the Japanese LED market leader whose researchers invented the blue and white LED technology, with full manufacturer datasheets and performance tested in the lab and in real applications. Low-cost modules often use LED chips of unknown origin, without certified data, so their quality and color vary from one purchase to the next.
- PCB design and materials: high-quality materials and a design without mechanical and electrical weak points, for good current flow, heat transfer and long-term reliability.
