Introducing the New LumiFlex3090 Series: High-Performance Cree LED Strips for Professional Lighting

The new LumiFlex3090 with high efficacy Cree LEDs

Lighting design has evolved beyond simply adding more lumens. Today, performance is defined by a combination of efficiency, light quality, reliability, and consistency across real-world installations.

With the launch of our new LumiFlex3090 series, we bring together these critical factors into a single, high-performance flexible LED strip platform—engineered and manufactured in Germany, and powered by premium LEDs from Cree LED.

This new range is designed for professionals who need predictable results: lighting designers, luminaire manufacturers, architects, and engineers who cannot afford inconsistencies in light output or product quality.

A New Standard for Flexible LED Strips

The LumiFlex3090 series is built around a clear objective: deliver high luminous output, high efficiency, and high color quality in a format that is easy to integrate into demanding lighting systems.

Each 5-meter reel integrates 350 high-performance Cree LEDs, delivering up to 9450 lumens total output, depending on the selected color temperature. This creates a powerful and uniform linear light source for both direct and indirect lighting applications.

All variants offer CRI >90, 24VDC operation, 70 LEDs per meter, 120° beam angle, and a long lifetime of more than 60,000 hours.

What sets it apart from commodity flex strips

There is no shortage of 2835-package LED strips on the market. What differentiates them is not the package but what surrounds it: the LED source, the binning tolerance, the PCB construction, and the manufacturing process. These are the variables that determine whether a strip performs consistently over years of operation or degrades unpredictably within months.

Cree JB2835 — a traceable source

All four LumiFlex3090 variants use the Cree JB2835, sourced through the Cree LED Branding Partner Programme. This means the LEDs in every reel are traceable within Cree's authenticated supply chain — not grey-market components repacked under a recognisable name, which remains common in the flexible strip segment. Cree publishes certified photometric datasheets for the JB2835; our datasheet performance figures are measured at TJ = 65°C junction temperature, not at cold-start, reflecting conditions closer to actual installed operation.

With over 30 years of LED development experience, Cree is one of the few manufacturers that backs its component specifications with LM-80 test data and expert field support — a level of documentation that commodity sources rarely provide.

3-Step MacAdam binning

Colour consistency across strips is one of the most underspecified parameters in flexible LED procurement. A 5- or 7-Step MacAdam tolerance — common in commodity products — allows chromaticity variation that is visually detectable when two strips run side by side in a cove or linear channel. The LumiFlex3090 uses 3-Step MacAdam binning across all four CCTs, which keeps colour variation within a tolerance that is not perceptible under normal viewing conditions.

Reel-to-Reel manufacturing, made in Germany

The LumiFlex3090 is produced on our R2R Flex line in Germany — a fully automated, continuous-feed process. Unlike batch assembly, R2R moves the flexible PCB substrate through component placement, reflow soldering, and inspection as a single uninterrupted operation. There are fewer handling steps, fewer interconnects, and tighter placement tolerances than batch-produced strips. For specifiers buying multiple reels, this means lower variation between reels and more consistent field performance across an entire installation.

Single continuous PCB

Each reel is a single unbroken 5-metre flexible PCB — no soldered mid-strip joints. The integrated linear control circuit maintains stable current distribution across the full length, avoiding the brightness roll-off at the far end that is characteristic of simpler constant-voltage designs. The strip cuts every 100 mm at marked cut points; connection is via solder pads using standard lead-wire termination. Thermally conductive double-sided adhesive is included on the reverse for surface or profile mounting.

How to choose your colour temperature

Colour temperature is the single most consequential decision in any lighting specification — it cannot be corrected after installation without replacing the strips. The table below compares all four LumiFlex3090 variants across the parameters that matter most for specification: output, efficacy, typical applications, and the atmosphere each CCT creates.

2700K — warm white

The 2700K variant delivers 1780 lm/m at 155 lm/W at mains input. It is the closest approximation to incandescent light in the range — flattering to skin tones, warm natural materials, and wood finishes. It is the correct choice for hospitality, high-end residential, and any environment where relaxation and warmth are the design intent. It is not the right choice where visual tasks require colour discrimination, or where an energetic, alert feel is specified.

3000K — warm white, most versatile

The 3000K variant delivers 1820 lm/m at 159 lm/W. It is the broadest-application CCT in the range: warm enough for hospitality and residential contexts, crisp enough for commercial retail and office environments where a warm-neutral feel is specified. For projects where a single CCT must serve multiple zones or space types, 3000K is the most defensible specification choice.

4000K — pure white, highest efficacy

The 4000K variant delivers 1890 lm/m at 164 lm/W — the highest figures in the range. The neutral white CCT supports visual acuity and alertness without the clinical feel of 6500K. It is the natural choice for offices, healthcare environments, task lighting, workshops, and retail display where product colours must read accurately under artificial light. For specifiers where energy efficiency is the primary driver alongside colour accuracy, 4000K is the optimal selection.

6500K — cold white, daylight-aligned

The 6500K variant delivers 1870 lm/m at 162 lm/W. High-CRI performance at this daylight-aligned CCT is less common than at warmer colour temperatures, making this strip a technically specific choice: CRI >90 with 3-Step MacAdam binning at 6500K is a meaningful specification for laboratory, studio, inspection, and high-accuracy retail environments where colour fidelity under artificial light is non-negotiable. It is not suited to spaces where occupant comfort over extended periods is a design requirement.
