Frequently Asked Questions
What are the key specifications of 20480?
20480: 2835, 180, DC24V, 8 PCB, 3oz copper FPCB, cuttable Free Cut. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.
What makes the construction of this micro cut LED strip different?
It is built as a micro cut LED strip on 3oz copper FPCB with a cutting unit of Free Cut and an LED pitch of 5.568mm, so it holds its electrical and mechanical performance where standard strips fail.
Can DENO customise this micro cut LED strip for a project?
Yes. DENO manufactures the Micro-Cut 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 makes a full spectrum LED strip different from a normal high CRI strip?
A full spectrum LED strip fills the cyan gap and the deep red region that standard phosphor LEDs leave weak, reaching Ra 95 to 98 with R9 above 90. Colours, skin tones and printed material look closer to daylight, which is why museums, retail and studios specify it.
How short can you cut a micro-cut LED strip?
Cut points come as close as 12.5 mm, against 50 to 100 mm on a conventional cuttable LED strip. Short segments matter in cabinets, stair nosings, signage letters and display cases where a standard cut interval would leave a dark gap at the end of the run.
Full Spectrum LED Strip — Buyer Questions
What makes a full spectrum LED strip different from a normal high CRI strip?
A high CRI board raises the average of eight pastel test colours; a full spectrum LED strip reproduces a continuous 380–780 nm curve with no cyan gap and a low blue peak. DENO builds them at Ra 95+ with R9 above 90, so saturated reds, timber and skin tones render as they do in daylight rather than simply scoring well on a datasheet.
Is a violet-excited full spectrum LED better than a blue-chip white LED?
For colour fidelity, yes. A violet-excited LED pumps a multi-phosphor blend with a ~405 nm die, filling the 420–500 nm region that a 450 nm blue chip leaves as a spike and a dip. The trade-off is efficacy: expect 80–110 lm/W instead of 130–150 lm/W. Blue-pump Ra 95 remains the better choice where lumens per watt drive the energy calculation.

What CRI and R9 values do your full spectrum LED strip lights reach?
Standard production is Ra 95+ with R9 greater than 90, typically TM-30 Rf 93 and Rg around 100. Every reel ships with spectral test data, and 1-SDCM binning is available when several reels must match visually in the same room. Ra 98 selections can be produced for gallery and film work on a project basis.

Which full spectrum model should I choose for a shallow cove?
Pick density by mounting depth: with 6–12 mm between board and diffuser the 8 mm 256 LEDs/m 2216 build at 3.9 mm pitch stays dot-free, while the 10 mm 128 LEDs/m board is the efficient choice behind deeper profiles. For runs that must not drift in brightness, the 12 mm constant-current board regulates each segment independently.

Are full spectrum LED strips available in 24V and are they dimmable?
All five DENO full spectrum boards are 24V, which keeps current low enough for 5 m single-feed runs and 10 m with dual feed. They dim on PWM, 0–10V, DALI and TRIAC drivers down to 1% without colour shift, because the phosphor blend is fixed rather than mixed from separate colour channels.

Can full spectrum LED strip lights be used for plants or human-centric lighting?
Yes for both, within limits. The continuous spectrum supports supplementary horticulture and human-centric schemes where a magenta grow bar would be unacceptable, and melanopic content is tuned by CCT rather than by adding a channel. For dedicated high-PPFD growing, a purpose-built horticultural board is still the more efficient option.

Can I order a custom full spectrum LED strip — width, CCT or IP class?
Board width from 8 mm to 20 mm, 1800K–6500K including dual-CCT tunable white, 2 oz or 3 oz copper, free-cut segmentation and IP20 to IP68 protection are all configurable on the existing full spectrum stack-ups, so a non-standard build is a production setup rather than new tooling. MOQ and lead time are quoted per specification.
What wavelength range does the spectrum actually cover, and is the cyan gap really filled?
Emission runs continuously from 380 nm to 780 nm. On a violet-pump board the 405 nm die feeds a three-phosphor blend, so the 480–500 nm cyan region sits within roughly 15% of the neighbouring bands instead of collapsing into the dip a 450 nm blue chip leaves. Measured SPD files (5 nm resolution), TM-30 Rf/Rg and the duv figure ship with each production lot, so the curve can be verified rather than assumed.
Which colour temperatures are available, and can the CCT be tuned after installation?
Fixed CCT options run 1800K, 2200K, 2400K, 2700K, 3000K, 3500K, 4000K, 5000K and 6500K, all held inside a 3-SDCM ellipse and 1 SDCM on request. For adjustable schemes a dual-channel tunable board mixes two full-spectrum phosphor sets, so 2700K–6500K tuning keeps Ra 95 across the whole travel — unlike RGB-based tuning, which loses fidelity away from its calibration point.

Where is a continuous-spectrum board worth the efficacy penalty?
Museums and galleries (low UV, faithful pigment rendering), fashion and jewellery retail where saturated reds decide a purchase, dermatology and dental rooms, food halls, colour-grading suites and photo studios, plus high-end residential where timber and skin tones dominate. In warehouses, car parks and back-of-house corridors the 30–40% efficacy gap is not justified — a blue-pump Ra 80 board is the correct specification there.

How does the spectrum affect flicker, UV and blue-light exposure?
A 405 nm pump sits below the 450 nm blue-hazard peak, so the RG0 exempt-group rating is easier to hold at the same lux; UV-A leakage beyond the die is filtered by the phosphor layer and measures below 2 µW/lm, which suits archival display. Flicker is a driver property, not a spectral one: on constant-current segments DENO measures Pst LM below 1.0 and SVM below 0.4, so the same board stays camera-safe.

Can a continuous-spectrum board be built waterproof or in long outdoor runs?
Yes. IP65 silicone coating, IP67 extrusion and IP68 filled builds are all available, and the phosphor blend is unaffected by the encapsulation because it sits under the LED lens. For long façade or landscape lines the 12 mm and 20 mm constant-current versions hold brightness across 10 m per feed, and 48V variants extend that further where trenching cost dominates.
