Description
2835 CCT Tunable LED Strip Light | 10mm | 24V | 240LEDs | 50mm/cut | #17985
Tunable White CCT design offers both white light, making this lamp suitable for both work and leisure needs.
This tunable white LED strip features 2835 LED chips, creating a brighter, softer, and more uniform lighting effect.
With a high-density design of 240 LEDs per meter, it ensures even light distribution.
An 10mm narrow board design enhances installation compatibility, making it suitable for various tight spaces.
Light can be switched between warm and white using a controller, meeting a variety of lighting needs.
Ideal for decorative lighting, architectural lighting, commercial lighting, and home lighting in scenarios that require tunable white CCT effects.
Tunable White Led Strip built for cct smd strips projects.

Frequently Asked Questions
What are the key specifications of 17985?
17985: 2835, 240, DC 24V, 10mm PCB, 3oz copper FPCB, cuttable 12LEDs/50mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.
What colour temperatures and CRI options does this tunable white LED strip offer?
This model is supplied as a tunable white LED strip with high CRI options and the CCT range listed in the datasheet. DENO bins every batch for colour consistency, and custom CCT or spectrum combinations can be produced for project quantities.
Can DENO customise this tunable white LED strip for a project?
Yes. DENO manufactures the CCT SMD Strips series as an OEM and ODM supplier: reel length, colour temperature, CRI grade, PCB width, waterproofing and private labelling can all be specified. Request a quote for lead time and project pricing.
How does a tunable white LED strip mix colour temperature?
Two LED channels, typically 2700K and 6500K, sit on the same FPCB and are dimmed against each other. Mixing the channels sweeps the white point along the black body line while total output stays even, which is how a CCT LED strip supports circadian and human centric lighting schedules.
