BackMatrix-49-2080 Nichia LED Module tunnable white CRI80 2700-6500K 2400lm 98 LEDs 24V 10.1W 180° 28x28cm (16000 lm/sqm)

BackMatrix-49-2080 Nichia Tunable White LED Module 2700-6500K, 180° Beam Angle, 28 x 28 cm

The BackMatrix-49-2080 Tunable White brings adjustable color temperature to light boxes, luminous ceilings and backlit surfaces. Its 98 chip-scale packaged Nichia LEDs in two channels, warm white 2700K and cold white 6500K, have an ultra-wide 180° beam angle, so the light blends evenly behind a diffuser even in very shallow constructions. With a 2-channel controller, any color temperature between 2700K and 6500K can be set, from warm, relaxing light to bright, activating daylight: ideal for human-centric luminous ceilings in homes, offices, schools and healthcare, also in rooms with low ceiling heights.

Each channel delivers up to 1150 lm (2700K) or 1250 lm (6500K) at about 10 W, up to 2400 lm per module with both channels at full output. The module operates at 24 V constant voltage, needs no additional cooling, and is made in Germany with a 5-year warranty.

Applications of the BackMatrix-49-2080 Tunable White LED Module

Designed for even backlighting of large surfaces, the BackMatrix-49-2080 Tunable White is used in the following main applications:

• Billboards and luminous ceilings: For backlit billboards, large light boxes and luminous ceilings, BackMatrix-49-2080 Tunable White modules are mounted side by side behind the translucent surface to light it evenly from edge to edge. See our LED modules for luminous ceilings.
• Signage: In illuminated signs, logos and display boxes, the modules provide bright, uniform backlighting with a low number of components. The 180° LEDs keep signs and light boxes shallow. More about LED modules for signage backlighting.
• Backlighting behind translucent materials: Behind stretch ceilings, acrylic, onyx, marble, textiles or printed graphics, BackMatrix modules create evenly lit walls, ceilings, counters and 3D elements, as well as displays at trade fairs and exhibitions. Read our guide on how to create a light ceiling with LED modules.
• Tunable white and human-centric lighting: With a 2-channel controller, the color temperature of a luminous ceiling or wall can follow the time of day: activating, cooler light during the day and warm, dimmed light in the evening, supporting well-being and the natural circadian rhythm. Read more about Human Centric Lighting with adjustable intensity and color temperature.
• White light: Both channels provide clean, uniform white light with CRI above 80. Find out which color temperature suits your project in our guide Choosing the right color temperature for LED lighting.

Why BackMatrix for Large Illuminated Surfaces

• Fewer parts per square meter: each module covers 280 x 280 mm with an even grid of Nichia LEDs, so about 13 modules light one square meter, much faster to install than rows of LED strips or many small modules.
• Even light distribution: the regular LED grid blends into a uniform surface behind a diffuser, without visible hotspots, the basis for homogeneous light boxes, signs and luminous ceilings. Match the distance to the diffuser to the LED spacing and the beam angle, as described in our guide on LED pitch and distance to cover for optimum backlighting.
• Solder-free connection: an insulation displacement terminal accepts connection cables of up to 1 mm² (AWG 18), for example our cable SKU 37592, without soldering; we recommend the BackMatrix tool bit (SKU 95402). Holes on the board allow the cables to be fixed with cable ties.
• Simple 24 V system: modules are connected in parallel to one 24 V constant voltage power supply, so any number of modules can be combined to the size of the surface, limited only by the power supply and the cable cross-section.
• Consistent color: Nichia LEDs binned to a 3-step MacAdam ellipse keep brightness and light color uniform across all modules of a large surface.

Installation and Operation

• Mounting: fix the module flat on a stable surface, supporting the board at suitable mounting points; do not bend the board or clamp the components. No additional cooling is required.
• Connection: connect the modules with the solder-free insulation displacement terminal, using cables of up to 1 mm² (AWG 18), and fix the cables with cable ties through the holes on the board; soldering is possible as an alternative.
• Power supply: connect several modules in parallel to a stabilized 24 V DC constant voltage LED driver with short-circuit, overload and overtemperature protection, sized for the total load (up to 19.7 W per module with both channels at full output) plus a safety margin. For large surfaces, feed the modules in groups with adequately sized cables to keep the voltage drop low.
• Handling: observe standard ESD precautions, keep the modules away from aggressive chemicals, and store and operate them at 10% to 60% relative humidity.
• Safety: installation must comply with all applicable electrical and safety standards and should be carried out by a qualified electrician.

Why the BackMatrix-49-2080 Tunable White Outperforms Low-Cost LED Modules

Compared with low-cost LED modules, the BackMatrix-49-2080 Tunable White differs in three 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 strips 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.
• Realistic specifications: all values are measured at a junction temperature of 65°C, so the performance in our datasheet matches what you get in a real installation.
