LumiFlexTW-1080 Nichia LED Strip 2 in 1 Tunable white CRI80 2700-6500K 4850lm 24V 112 LEDs/m 5m reel (940+970lm/m and 7.68W/m)

LumiFlexTW-1080 Nichia 2-in-1 Tunable White LED Strip 2700-6500K

The LumiFlexTW-1080 Nichia 2-in-1 uses one of the most advanced tunable white LEDs available: the Nichia NF2W757G-MT. Each LED contains warm white 2700K and cold white 6500K chips under a single, small light emitting surface, so the color temperature is mixed directly in the LED. The result is a smooth transition from warm to cold white with excellent color uniformity, without the colored fringes, shadows or stripes that strips with separate warm and cold LEDs can produce, and without the need for bulky mixing distances.

With 560 LEDs on a 5 m reel (112 per meter), the strip delivers 940 lm per meter in warm white and 970 lm per meter in cold white at 7.68 W per meter and channel, with an efficacy of up to 126 lm/W. Thanks to linear control on the strip, the brightness remains constant over the whole length, and the light is homogeneous from batch to batch. This makes it ideal for cove and base lighting, kitchen and furniture lighting, exhibition stands and luminaire construction.

Applications of the LumiFlexTW-1080 Nichia 2-in-1 LED Strip

With its tunable white light and flexible format, the LumiFlexTW-1080 Nichia 2-in-1 is designed for the following main applications:

• Cove lighting: Installed in a ceiling or wall cove, the LumiFlexTW-1080 Nichia 2-in-1 produces soft, glare-free indirect light whose color temperature can follow the time of day or the occasion: warm light for a relaxed evening atmosphere in living rooms, hotels and restaurants, neutral or cool light for activity and concentration in offices, shops and kitchens. With 940 lm per meter in warm white and 970 lm per meter in cold white, it is ideal for ambient light from coves and accent lighting around furniture and architectural elements, and the 3-step MacAdam binning prevents visible color differences along long cove runs. Because the colors are mixed inside each LED, the light on the ceiling stays even, without colored fringes, even in shallow coves. Learn how to plan it in our cove lighting guide.
• Tunable white light: With a color rendering index above 80, the strip provides clean, uniform white light at every setting. Where color accuracy is critical, choose our CRI95 LumiFlexTW-3095. Find out which color temperature suits your project in our guide Choosing the right color temperature for LED lighting.
• Human-centric lighting with 2 channels: The warm white and cold white channels are controlled separately with a 2-channel (tunable white) controller, so you can set any color temperature between 2700K and 6500K and the brightness independently. Cooler, brighter light during the day supports alertness and concentration, while warmer, dimmed light in the evening supports relaxation, the principle of human-centric lighting for homes, offices, schools, hotels and care facilities.

Installation and Operation

• Cutting: the strip can be cut with scissors every 62.5 mm, at the marked cutting points.
• Mounting: clean and degrease the surface, then fix the strip with its self-adhesive tape. For the best heat transfer, light diffusion and mechanical protection, we recommend mounting it in one of our aluminum profiles.
• Connection: solder leads to the connection pads provided for this purpose, observing the marking of the warm white and cold white channels.
• Power supply: operate the strip with a stabilized 24 V DC constant voltage LED driver that has short-circuit, overload and overtemperature protection.
• Control: connect the two channels to a 2-channel (tunable white) LED controller or dimmer to set color temperature and brightness, for example a wireless Casambi controller or a wall dimmer.
• Driver sizing: each channel draws up to 38.4 W (1.6 A) per 5 m reel; size the driver for both channels at full output, 76.8 W per 5 m reel, plus a safety margin.
• 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 LumiFlexTW-1080 Nichia 2-in-1 Outperforms Low-Cost LED Strips

Compared with low-cost tunable white LED strips, the LumiFlexTW-1080 Nichia 2-in-1 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.
