The short answer
Ultra-narrow COB LED strip is designed for slim channels, furniture grooves, narrow shelves and compact decorative details where standard-width strips cannot fit cleanly.
Doen Lighting's COB range includes narrow options such as 3mm and 5mm versions for buyers who need smooth light in tight installation spaces.
When to use 3mm COB LED strip
A 3mm COB LED strip can fit very narrow grooves and compact decorative channels. It is useful for furniture details, display edges and small architectural features where the strip must remain hidden.
The trade-off is that narrow PCB width can limit power, connector choice and heat management, so sample testing in the real profile is important.
When to use 5mm COB LED strip
A 5mm COB LED strip gives a little more room for brightness and installation handling while still fitting many slim profiles. It can be a practical middle option for furniture, shelves and decorative linear lighting.
Buyers should compare 3mm and 5mm samples with the same CCT, CRI, profile and diffuser to decide which version balances appearance and output.
Brightness, heat and connection trade-offs
Narrow COB strips can create a clean line, but high wattage in a small space may require better heat management. Aluminum profiles can improve both appearance and operating stability.
Connector space is also limited. For ultra-narrow COB, soldering or factory-prepared cables may be more reliable than standard clip connectors.
Profile fit checklist
Before ordering, confirm internal profile width, diffuser distance, cable exit, cutting unit, bending route, power feed position and whether the installer needs field cutting.
Send drawings or profile photos to the supplier so the sample can be matched to real installation conditions.
FAQ
What is ultra-narrow COB LED strip?
It is a COB LED strip made with a narrow PCB, such as 3mm or 5mm, for slim channels and compact profiles.
Is 3mm COB LED strip bright enough?
It depends on the wattage and application. Test samples in the actual profile before bulk order.
Can ultra-narrow COB strip use connectors?
Some projects may need soldering or factory-prepared cables because connector space is limited.
