Key Features

• 3mm width — narrowest in the series – Fits slim aluminium profiles, cabinet grooves, and tight architectural recesses where standard 8mm and 10mm strips cannot be installed.
• SDCM ≤3 colour consistency – The tightest colour tolerance across the D series. Adjacent reels and separate cabinet runs match visibly, which matters when a single kitchen or showroom uses multiple lengths.
• CRI 90 colour rendering – Renders timber grain, fabric, food, and merchandise accurately. Standard Ra80 strips flatten colour distinction in display applications.
• Dot-free continuous emission – COB construction spreads phosphor across the full surface, eliminating the LED dot pattern visible on SMD strips at close range.
• 10mm cut interval – The shortest cut pitch in the low-voltage single colour range, allowing accurate length matching in short cabinet sections without wasted strip.
• Six colour temperature options – 2700K, 3000K, 3500K, 4000K, 5000K, or 6500K specified at order stage.
• Extensive connector ecosystem – 2P board connectors, single and double lead wires, in-line joiners, and L-shaped transition pieces support corners and extensions without soldering.
• L80B20 at 20,000 hours – Retains 80% of initial output at 20,000 hours, with MTBF rated at the same figure.

Specifications

Materials & Finish

• Construction: COB (chip-on-board) flexible strip with phosphor coating applied across the full emitting surface, producing a continuous light line rather than discrete points.
• Profile: W3 × H1.65 ± 0.5 mm — the smallest cross-section in the D series, allowing installation in channels and rebates that will not accept wider strips.
• Surface treatment: coated silicone with phosphor-based colour temperature tuning.
• Colour performance: Ra 90 with SDCM ≤3, the tightest binning tolerance in the series.
• Thermal range: -25 °C to +45 °C operating; -40 °C to +60 °C storage, tolerating unheated warehouse conditions in winter.
• Photometric stability: L80B20 at 20,000 hours — 80% output retention, a tighter criterion than the L70 standard commonly quoted.
• Mechanical: flexible construction rated for bending, folding, and twisting without structural fatigue; 15,000 switching cycles.

Assembly & Installation

Tools needed: scissors or side cutters, and a clean dry cloth for surface preparation.

Steps:

1. Measure the run and confirm the total load against the 12V DC power supply capacity at 6W per metre.
2. Clean the mounting surface — adhesive bonding fails on dust, grease, and residual cleaning product.
3. Cut only at the marked 10mm intervals if length adjustment is needed.
4. Peel the backing film and press the strip firmly along its full length.
5. Connect using the appropriate 2P accessory: board connector, single-lead wire, double-lead wire, in-line joiner, or L-shaped transition.
6. Apply power. The strip illuminates immediately — no controller or driver programming required.

Note on the 3mm profile: the narrow cross-section makes this the most flexible strip in the series along its length, but also the most delicate at the cut points. Support the strip at both sides of a cut when handling, and avoid pulling on the connection joint during installation.

Applications

• Under-cabinet kitchen lighting – Fits the shallow rebate under wall units where wider strips protrude below the cabinet edge.
• Display and retail cabinets – CRI 90 and SDCM ≤3 render merchandise colour accurately in jewellery, cosmetics, and premium retail fixtures.
• Wine cabinets and bar shelving – Narrow profile disappears into shelf edges; high colour rendering displays labels and glassware.
• Wardrobe and closet interiors – Slim enough for shelf undersides and hanging rail recesses.
• Cove and perimeter lighting – Continuous dot-free line along ceiling coves and architectural reveals.
• Automotive and vehicle interiors – Compact section suits dashboard, door panel, and footwell ambient lighting.
• Showcase and museum display – Accurate colour rendering for exhibited objects and artwork.

FAQ

Q: How narrow is this COB LED strip light, and what does 3mm actually allow?
A: The strip measures W3 × H1.65 mm. It fits slim aluminium profiles, cabinet grooves, and shallow architectural recesses that cannot accept the 8mm and 10mm strips in the range. Where a channel is already installed, confirm its internal width before ordering — 3mm is the narrowest option available in the D series.

Q: What does SDCM ≤3 mean for a cabinet installation?
A: SDCM measures colour variation between LEDs and between production batches. At ≤3, differences are not visible to the eye under normal viewing. In a kitchen using several separate strip runs, or a showroom with multiple cabinets, all sections appear as the same white. This is the tightest tolerance in the D series; most strips here are ≤5.

Q: Can the colour temperature be changed after installation?
A: No. Colour temperature is fixed at production — select one of 2700K, 3000K, 3500K, 4000K, 5000K, or 6500K when ordering. For switchable warm and cool white, specify a Dual White model from the D series instead.

Q: Why choose CRI 90 over a standard Ra80 strip?
A: CRI 90 renders colour closer to natural light. In display cabinets, retail fixtures, and wine storage, Ra80 visibly flattens the distinction between similar tones — timber grain, fabric, and product colour all read less accurately. For general ambient lighting where colour accuracy is not critical, the Ra80 models are the more economical choice.

Q: How short can the strip be cut?
A: Every 10mm along the marked cut points, the shortest interval among the low-voltage single colour models. This allows close length matching in short cabinet sections without leaving unused strip.

Q: What is the minimum order quantity and lead time?
A: MOQ is 50 sets with a lead time of 15–21 days. The strip is supplied on 5m reels, 100 reels per carton, and ships from Guangzhou or Shenzhen.
