I’m currently planning a linear lighting project and still in the product selection stage.
Project background:
Application: Indoor commercial space
Installation: Recessed aluminum profile
Strip length: Multiple continuous runs
Main requirements: Even light output, no visible dots
Certain requirements for CRI and long-term stability
I’m deciding between COB LED strips and high-density SMD LED strips, and would appreciate input from those with real project experience:
1.Is the difference noticeable in real applications?
2.Which option performs better in terms of maintenance and stability?
3.Are there any commonly overlooked factors during selection?
Looking for practical experience and decision logic, not just spec comparisons. Thanks!
We’ve used both COB and high-density SMD LED strips in several indoor commercial linear lighting projects, so I can share some practical observations.
Visual effect:
In recessed aluminum profiles, COB provides a more continuous light output with virtually no visible dots. High-density SMD can look quite uniform as well, but individual light points may still be noticeable at close range.
Stability and maintenance:
High-density SMD strips are generally easier to maintain, as individual sections can be replaced more flexibly. COB strips have a simpler structure, but if damage occurs, replacing a full section is usually required.
Selection advice:
If visual continuity and a premium look are the priority, COB is often the safer choice. If maintenance flexibility is more important, high-density SMD may be the better option.
Overall, there’s no absolute right or wrong choice — it depends on installation conditions and project priorities.
