Problem & Solution
Standard LED strips often suffer from visible 'dotting' where individual diodes create bright spots rather than a continuous light output. Additionally, traditional 8mm or 10mm wide strips are frequently too bulky to fit inside narrow aluminum tracks, cabinet crevices, or minimalist furniture gaps.
This 3mm ultra-thin COB (Chip-on-Board) LED strip addresses both problems directly. By placing 400 LEDs per meter under a uniform phosphor layer, it delivers continuous light without harsh dots. Its 3mm footprint allows seamless installation into tight spaces where standard width LED ribbons cannot fit.
Who Is It For?
This product is designed for DIY lighting builders, cabinet installers, and homeowners seeking discreet accent lighting. It is particularly useful for individuals creating micro lighting fixtures, display case illumination, or subtle cove accents in narrow spaces where regular width light strips are visually obtrusive.
Key Features
- 3mm Ultra-Thin PCBFits into tight channels, narrow furniture grooves, and micro aluminum profiles where standard 8mm or 10mm strips cannot fit.
- COB (Chip-on-Board) TechnologyProvides continuous, dot-free linear illumination across the ribbon without visible hot spots.
- High Density 400 LEDs/mDelivers dense light output for seamless accent lighting.
- Multiple Color Temperatures (3000K / 4000K / 6000K / Colorful)Allows selection of warm white, natural white, cool white, or colorful options to match decor preferences.
- Dimmable 12V OperationEnables brightness adjustment when paired with a compatible 12V DC dimming driver or controller.
- Flexible Circuit BoardAllows gentle curving along smooth interior surfaces and contoured furniture layouts.

Pros & Cons
Pros
- 3mm width allows installation in extremely narrow channels and tight spaces
- COB phosphor layer eliminates diode hot spots for continuous linear glow
- High diode density (400 LEDs/m) provides uniform light distribution
- Offers multiple color temperature variants (3000K, 4000K, 6000K) for different ambiance needs
Cons
- 12V power adapter and dimmer controller are not included and must be sourced separately
- 3mm narrow PCB requires precise soldering skills if cutting and re-joining segments
- Ingress protection (waterproofing) rating is not specified in available product data
FAQ
No. This is a 12V DC LED strip. It requires a compatible 12V power supply (transformer) to operate from standard AC mains voltage.
Yes, the strip supports dimming, but you must connect it to a compatible 12V LED dimmer controller or dimmable power supply.
Flexible LED strips generally feature marked copper cut points. However, because this strip is only 3mm wide, soldering wires to cut sections requires delicate handling.
The IP rating (water resistance) is not specified in the available product data. Check the listing details before considering use in moist or outdoor environments.
Final Verdict
Recommended for DIY project builders and crafters needing smooth, continuous light inside tight gaps under 5mm wide. Skip this model if you require a complete ready-to-plug kit with an included power adapter or guaranteed outdoor waterproofing. Verify that you have a 12V DC power source ready before purchasing.
