LumiFlex3090 Cree LED Strip warm white CRI90 2700K 8900lm 24V 70 LEDs/m 5m reel (1780lm/m 12.5W/m)

LumiFlex3090 Professional High-Efficiency CRI90 LED Strip Warm White 2700K

The LumiFlex3090 2700K is a high-efficiency, high color rendering LED strip for hospitality, residential and architectural projects where warm light, accurate colors and low energy consumption must go together. It is built with 350 Cree JB2835 mid-power LEDs per 5 m reel (70 per meter) and delivers 8900 lm per reel (1780 lm per meter) at only 12.5 W per meter. With 142 lm/W at a junction temperature of 65°C and a mains voltage luminous efficacy of 155 lm/W, it reaches energy efficiency class D, a very economical choice for projects where operating costs matter.

A color rendering index above 90 and LEDs binned to a 3-step MacAdam ellipse ensure accurate colors and visually identical light from strip to strip, which is essential wherever several runs are installed in the same field of view. The strip is made from one continuous 5-meter printed circuit board, produced in our reel-to-reel line in Germany, so there are no soldered joints between sections, and integrated linear current control keeps the brightness constant over the entire length.

The LumiFlex3090 can be cut every 100 mm and is mounted quickly with its double-sided, heat-conducting adhesive tape. With its slim 8 mm width, 1.2 mm height, 24 V constant voltage operation and full dimmability, it fits into aluminum profiles, coves, troffers and custom luminaires without additional cooling, and with only 2.6 A per 5 m reel it keeps the load on drivers and wiring low.

Applications of the LumiFlex3090 LED Strip 2700K

Thanks to its combination of very high efficacy, high color rendering and a slim, flexible format, the LumiFlex3090 2700K is designed for the following main applications:

• Linear lighting: Mounted in an aluminum profile with an opal diffuser, the LumiFlex3090 creates continuous, even lines of light for ceilings, walls and furniture. With 70 LEDs per meter (a pitch of about 14 mm), choose a profile with enough distance between strip and diffuser, or a cover with high diffusion, for a dot-free line; for very shallow profiles, a strip with 140 LEDs per meter is the better choice. The absence of soldered joints along the 5 m reel ensures a perfectly uniform line. With 1780 lm per meter, one strip covers accent and ambient lighting, while two strips in parallel reach the brightness needed for general lighting. Read more in our guides on creating lines of light with LED strips and designing efficient LED linear lamps.
• Cove lighting: Installed in a ceiling or wall cove, the strip produces soft, glare-free indirect light. Its output of 1780 lm per meter is ideal for strong ambient room light from a single cove line, and the 3-step MacAdam binning prevents visible color shifts along long cove runs. The 2700K light color creates a cozy, intimate warm white light, well suited to living rooms, bedrooms, hotels, restaurants and boutique retail. Learn how to plan it in our cove lighting guide.
• Troffer and panel lighting: For troffers and LED panels in suspended ceilings, several LumiFlex3090 strips can be mounted in parallel on the base plate behind the diffuser. The slim 8 mm PCB, high efficacy and CRI>90 make it a high-quality replacement for fluorescent tubes in reception areas, hotels, shops and other spaces where a warmer, welcoming light is preferred. More about LED strips and modules for troffer lights.
• High-quality white light: With a color rendering index above 90, the LumiFlex3090 reproduces colors more faithfully than standard CRI80 LED strips, while its very high efficacy keeps energy consumption low. 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.

Installation and Operation

• Cutting: the strip can be cut with scissors every 100 mm, at the marked cutting points.
• Mounting: clean and degrease the surface, then fix the strip with the double-sided, heat-conducting adhesive tape. For the best heat transfer, light diffusion and mechanical protection, we recommend mounting it in one of our aluminum profiles.
• Connection: connect the strip by soldering leads to the connection pads provided for this purpose.
• Power supply: operate the strip with a stabilized 24 V DC constant voltage LED driver that has short-circuit, overload and overtemperature protection. A full 5 m reel draws 62.5 W (2.6 A).
• Handling: avoid sharp bending and mechanical stress on the components, observe standard ESD precautions, and keep the strip away from aggressive chemicals. Store and operate it 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 LumiFlex3090 Outperforms Low-Cost LED Strips

Compared with low-cost LED strips, the LumiFlex3090 differs in three areas that decide how long a lighting installation performs well:

• LED quality: we use only genuine Cree JB2835 LEDs. As a member of the Cree LED branding partner program, we source them through Cree's authenticated supply chain, 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 varies from one purchase to the next.
• PCB design and materials: a single continuous circuit board made of high-quality materials, designed without mechanical and electrical weak points, with integrated linear control for constant brightness. This gives better 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, even at high operating temperatures that would damage many other strips.
