Flex 240 xCCT: Technical Specifications for a Dimmable LED Strip with Color Temperature Control

Flex 240 xCCT is a flexible LED strip designed for projects where you need to adjust the color temperature without changing products or duplicating installations.

Its CCT technology allows the light to be adjusted between 2,700K and 6,500K by combining warm and cool LEDs using a compatible dimmer. This makes it possible to adapt the lighting to different scenes, uses, or visual needs within the same space.

In addition to its CCT control, the Flex 240 xCCT stands out for its CRI >90% and for its particularly impressive color rendering in the mixing channel, where it achieves a CRI of 94.9% and an R9 of 85.6% at 4,400K. This is particularly relevant in applications where color accuracy is technically or commercially important.

General characteristics

Parameter	Technical data
Product	Flex 240 xCCT
Format	Flexible LED strip
Dimensions	5,000 × 10 × 1.5 mm
Cutting width	50 mm
Average voltage	24 V
Power Consumption	9.6 W/m
LED Type	SMD 2216
Number of LEDs	240 LEDs/m
PCB	Flexible copper

The high density of 240 LEDs/m results in a more continuous light line, especially when integrated into suitable profiles or indirect lighting solutions.

Key Lighting Specifications

Parameter	Value
CCT Range	2,700K to 6,500K
Luminous flux	≈ 774 lm/m
Efficiency	≈ 81 lm/W
CRI	> 90%
Beam of light	120°
Dimmable	Yes
Flicker-free	Yes, without a dimmer

Flex 240 xCCT is designed for applications where light quality and visual versatility are more important than a fixed color temperature. Its CRI >90% provides adequate color rendering for interior architecture, decor, commercial furnishings, and product displays.

High CRI and R9 performance

The CRI indicates a light source’s ability to reproduce colors naturally. In Flex 240 xCCT, the CRI remains above 90 in the main settings.

The most distinctive feature is found in the 4,400K mix, where the product achieves:

Featured Settings	CRI	R9
4,400K Mix	94.9%	85.6%

The R9 value is particularly important because it evaluates the reproduction of saturated red, a critical color in many materials and products.

Good R9 performance helps improve rendering:

Skin tones
Textiles
Woods
Warm finishes
Cosmetics
Feeding
Decorative surfaces
Premium Products in Retail

For this reason, the Flex 240 xCCT should not be presented merely as a dimmable CCT LED strip, but rather as a variable white light solution with good color rendering.

Performance by Color Temperature

Settings	Lumen	CRI / R9	TM-30-18 RF	Recommended for
2,700K	≈ 726 lm/m	CRI 91.7% / R9 57.4%	RF 91%	Warm environments, relaxation areas, hospitality, residential spaces, home décor, and comfortable indirect lighting.
4,400K Mix	≈ 774 lm/m	CRI 94.9% / R9 85.6%	RF 90%	Retail, display cases, showcases, materials, textiles, cosmetics, commercial furniture, and spaces where color accuracy is a priority.
6,500K	≈ 822 lm/m	CRI 92.6% / R9 73.3%	RF 88%	Spaces requiring greater visual clarity, definition, technical precision, and work areas.

The 4,400K color temperature offers the most interesting technical balance between luminous flux, color rendering, and visual naturalness. This setting is particularly useful when seeking neutral light with high color fidelity.

Durability and Stability

Parameter	Value
Service life	> 36,000 hours
Maximum temperature	60 °C
% of failures	Category F10
Luminous Flux Maintenance	Category B L70
Color Coordinates	5-step MacAdam ellipse

MacAdam’s 5-step ellipse helps maintain adequate color consistency between sections, which is important in visible linear installations or continuous runs.

Installation and Assembly

Flex 240 xCCT is designed for indoor use.

For proper installation, we recommend:

Weld cables and sections at 350°C
Use flux paste to improve adhesion
Do not overlap the pads between LED strips
Insulate connections with heat-shrink tubing
Do not cover the LEDs with heat-shrink tubing
Avoid power strips with screws
Use Easyconnector for connection wiring
Mount the strip so that it is centered and flat on the profile

At corners, it is recommended not to use crimp connectors but to use 0.3 mm bare, rigid wire bent at a 90° angle.

Recommended Profile: Flex Cover

For safer and cleaner integration, this system allows for:

Protect the LED strip
Improving visual integration
Organize the installation for decorative or architectural applications

The wiring diagram includes a 24V power supply and a 2- to 4-channel dimmer.

Technical Differences Compared to a Generic CCT LED Strip

Flex 240 xCCT delivers value through a combination of:

240 LEDs/m for greater visual continuity
CRI >, 90% within the usable range
R9 85.6% in a 4,400K blend
CCT range from 2,700K to 6,500K
50 mm cutting width
Flexible copper PCB
Multichannel Dimmer Compatibility
Recommended installation on a Flex Cover profile

It’s not just a dimmable white LED strip. It’s a flexible solution designed to integrate ambient lighting control, color quality, and linear continuity into professional projects.
