Advantages
The Super Slim 3mm Cob Led Strip's 3mm width is a game-changer for space-constrained projects, solving the frustration of ill-fitting lighting solutions:
Seamless Integration:
At just 3mm wide, the ultra slim COB strip fits into 4mm-wide grooves, narrow furniture edges, and tiny display case gaps where standard 5mm+ COB strips won't fit.
Extreme Flexibility:
The ultra-thin PCB supports a minimum bending radius of 3mm, making it ideal for curved surfaces like circular shelves, arc-shaped signage, or furniture contours.
Discreet Aesthetics:
The slim design stays hidden when installed, creating a "floating light" effect.
◆ Ulti-Voltage Compatibility (DC5V/12V/24V): Adapt to Any Project
3mm Ultra Thin 400Leds/m 5V 12V 24V Cuttable's multi-voltage design eliminates the need for separate strips for different Projects, streamlining inventory and reducing hassle:
◆ DC5V for Safety & Portability: Perfect for residential use, DIY projects, or battery-powered setups (e.g., camping gear, temporary displays). DC5V's low voltage eliminates electrical shock risks, making it safe for use around children and pets.
◆ DC12V for Balanced Performance: Ideal for medium-scale projects (e.g., home shelves, small retail displays) with a balance of safety and run length (up to 15 meters single-end run).
◆ DC24V for Large-Scale Commercial Use: Supports long single-end runs up to 25 meters (≤2% brightness variation) for architectural lighting, building facades, or large retail spaces.
400chip/m Density & Multi-Color Options
With 400 high-brightness Epistar chips per meter and 7 single-color options (Blue/Green/Red/Pink/Purple/Yellow/White), the strip delivers uniform, vivid illumination:
♦ Seamless "Light Sheet" Effect: The dense chip layout eliminates hotspots and visible diodes, even at 3cm viewing distance.
♦ Vivid Single-Color Impact: Each color option is calibrated for true-to-tone performance (e.g., 6500K cool white for clarity, warm yellow for coziness, vibrant red for accent lighting).
♦ Energy Efficiency: With wattages as low as 5.5w/m (DC5V) and 7w/m (DC12V/24V), the COB strip consumes less power than standard 10w/m slim COB strips while delivering 800 lumens/m of bright light.
Wiring Options for Ultra Slim 3mm 400leds COB Strip
We offer three practical wiring solutions to fit diverse installation needs:
1.DC Head: Pre-installed standard DC connector for direct plug-and-play with DC power supplies, ideal for quick setups.
2. USB Head: Integrated USB connector, compatible with USB adapters or power banks-perfect for portable use like pop-up displays or DIY projects.
3. Naked Black/Red Wire: Exposed 10cm tinned copper wires (black for GND, red for VCC) for soldering or custom wiring, suitable for commercial installations requiring stable connections.
▲ All options maintain the COB strip's slim profile and CE/ROHS compliance, ensuring safe, reliable power transmission for DC5V/12V/24V setups.

FAQs
Q1: How do I choose the right voltage for my project?
A: Opt for DC5V for small, portable setups (≤10m) or residential use (safety priority). DC12V works for medium-scale projects (≤15m) like home or small retail displays. DC24V is ideal for large commercial projects (≤25m) like building facades or big-box stores. Our team can recommend based on your project size and power setup.
Q2: Can I cut the ultra slim 3mm COB strip to custom lengths, and how small can I go?
A: Yes-cut only at the marked intervals (10mm for DC5V/12V, 20mm for DC24V), clearly labeled with a scissors icon. The smallest usable segment is 10mm (DC5V/12V) or 20mm (DC24V), perfect for tiny spaces like jewelry display compartments. For IP65/67 variants, seal cut ends with included silicone glue to maintain waterproofing.
Q3: Is the 3mm width less durable than wider ultra slim 3mm COB strips?
A: No-our 3mm COB strip uses a reinforced double-layer FPC and 2Oz copper foil, ensuring durability comparable to 5mm COB strips.
Q4: Can I connect multiple ultra slim 3mm COB strip together?
A: Yes-you can daisy-chain up to the maximum single-end run (10m for DC5V, 15m for DC12V, 25m for DC24V) with a single power supply. For longer runs, add a power injector at the maximum run length to avoid voltage drop.
Q5: Does the ultra slim 3mm COB strip work with smart home systems like Alexa or Google Home?
A: Yes-pair it with a Tuya WiFi controller (compatible with our multi-voltage design) to control brightness and power via voice commands or the Tuya app. g room accent light" for instant ambiance.
