Ultra-Narrow PCB
3mm and 5mm widths fit compact channels and detailed joinery.
Continuous Linear Light for Restricted Spaces
The BrotherLED 3–5mm COB LED strip series is designed for slim profiles, shelving, display fixtures and furniture details where standard-width tape is too large.
Seven catalogue models combine compact 3mm or 5mm PCBs with 300 to 480 chips per meter.

Product Features
Continuous COB Output
Closely mounted chips and a continuous emitting layer reduce visible spotting.
Low-Power 3mm Options
The two 3mm models use 5 W/m or 6 W/m for compact accent applications.
Seven Model Choices
Select from 300 to 480 chips per meter and multiple voltage configurations.
White & Color Options
Standard white CCTs and decorative colors are listed in the catalogue.
Flexible Installation
The narrow flexible tape follows straight and gently curved architectural details.
Made for Tight Installation Spaces
Standard LED tape can be too wide for miniature channels and precision furniture details. This series offers 3mm and 5mm flexible PCBs while retaining a continuous COB light-emitting surface.
Choose 3mm or 5mm
The 3mm versions prioritize compact dimensions and lower power. The 5mm range expands the available chip densities and reaches 14 to 16 W/m. Match the strip width to the channel before selecting voltage and power.
Color and Project Planning
Available catalogue colors include four standard white CCTs and multiple decorative colors. These products are listed as IP20 for dry indoor projects, so protected constructions should be specified separately where required.
Applications
Bedroom Accent Lighting
Add concealed colored or white light around beds, panels and ceiling edges.
Slim Ceiling Details
Fit narrow channels around compact ceiling coves and perimeter features.
Wall & Joinery Lines
Integrate continuous light into wall panels, display niches and custom furniture.

Frequently Asked Questions
How narrow is this COB strip series?
It includes 3mm and 5mm flexible PCB options.
Which version is best for a miniature channel?
Confirm the internal width of the channel first. The 3mm models are the narrowest, while 5mm models provide more power and density options.
What is the power range?
The catalogue lists 5 to 16 W/m, depending on model.
Can I order DC24V?
Yes. DC24V is listed across the series, with DC5V and DC12V available on selected models.
Can this strip be used in wet locations?
The listed models are IP20 for dry indoor use. Contact us for a suitable protected construction.
Custom LED Solution
Working with a very slim channel?
Send us the channel width, run length, voltage, color and target power so we can match the correct 3mm or 5mm model.
