Description
10mm | 24V | 120LEDs | 50mm/cut | #2176-B | 2835 1 SDCM Classic High Consistency LED Strip Light By adopting 1-Step (1 SDCM) binning LEDs, chromaticity tolerance is strictly controlled within one MacAdam Step at the source. Built on the classic 2835 SMD LED platform, this strip features 120 LEDs per meter, delivering stable output and smooth linear illumination. Compatible with multiple dimming systems including PWM, DALI, and 0–10V, the strip enables flexible and precise lighting control. Ideal for retail lighting, architectural lighting, display showcases, and high-end residential applications.
We use 99.99% gold wire, large-size chips, and thickened FPCB, backed by a 5-year warranty.

Frequently Asked Questions
What are the key specifications of 2176-B?
2176-B: 2835, 120, 24V, 10 PCB, 3oz copper FPCB, cuttable 6LEDs/50mm, IP20/IP54/IP65/IP66/IP67/IP68, CRI Ra≥90. 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 1 SDCM LED strip offer?
This model is supplied as a 1 SDCM LED strip with CRI Ra≥90 and 2700-6500 colour temperature options. DENO bins every batch for colour consistency, and custom CCT or spectrum combinations can be produced for project quantities.
Can DENO customise this 1 SDCM LED strip for a project?
Yes. DENO manufactures the 1 SDCM 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.
What does 1 SDCM mean on a high CRI LED strip?
1 SDCM means every LED falls inside one MacAdam ellipse, so no visible colour difference exists between reels or between fixtures. Combined with Ra>90 and R9>50, this high CRI LED strip keeps white points matched across a whole project, which matters in retail, museum and hospitality installations where several runs sit side by side.
1 SDCM LED Strip — Buyer Questions
What does 1 SDCM mean on an LED strip?
SDCM is the Standard Deviation of Colour Matching — the size of the MacAdam ellipse a batch's chromaticity falls inside. A 1 SDCM LED strip keeps every LED within one ellipse of the target point, which is below the threshold the human eye can resolve, so a wall wash reads as one continuous colour instead of a series of slightly different whites.

3 SDCM vs 1 SDCM — is the difference visible on a real installation?
On a single short run, rarely. On a long cove, a mirrored pair of coffers or two reels butted end to end, 3 SDCM shows as a visible pink-to-green drift between sections, while 1 SDCM does not. Specify 1 SDCM whenever two lit surfaces are seen at once, on white joinery, or in retail and gallery lighting where the colour of the merchandise is the product.

How does DENO hold 1 SDCM colour consistency across a production batch?
Three controls stack: single-bin LED sourcing from one wafer lot, in-line chromaticity sampling on the SMT line, and reel-level records so a repeat order can be matched to the original batch. Boards outside the ellipse are pulled before packing rather than blended into the run.
Will a re-order months later still match my installed 1 SDCM LED strip?
Yes, when the original batch reference is quoted on the purchase order. DENO archives the bin and reel data for each 1 SDCM build, so a replacement section or a phase-two extension is produced from the same bin instead of the current stock bin — the usual cause of a mismatched repair on architectural projects.

Does tight colour binning affect brightness or efficacy?
Not measurably. Binning narrows chromaticity, not flux: a 1 SDCM board is drawn from the same flux bin as the standard build, so lm/W and lm/m stay on the published matrix. What does change is yield, which is why colour-critical builds carry a small premium over 3 SDCM tape.
Which applications actually need a 1 SDCM LED strip?
Museum and gallery lighting, retail displays and cosmetics counters, hotel and residential coves with sightlines across several bays, film and photo studio fill, and any white-on-white joinery detail. For back-of-house, machine and signage work 3 SDCM is normally sufficient and the cheaper specification.
