Description
2835 2-in-1 CCT Tunable LED Strip Light | 10mm | 12V | 120LEDs | 25mm/cut | #19937 Outfitted with 128 LEDs/m using a 2-in-1 CCT chip, it delivers a smooth transition between warm and cool white without noticeable dark spots. Only one loop CCT tunable LED strip is outfitted with extremely bright LED chips, fully compatible with standard PWM dimmers and smart control systems. By adopting 3-Step MacAdam binning (3 SDCM), these strips provide elegant, discreet, and highly consistent lighting across every batch. The flexible design is quite suitable for back lighting and general lighting in aluminum frames or under cabinets, commonly used by lighting designers in professional installations.
Tunable White Led Strip built for cct smd strips projects.

Frequently Asked Questions
What are the key specifications of 19937?
19937: 2835, 120, DC 12V, 10mm PCB, 2oz copper FPCB, cuttable 3LEDs/25mm. 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.
