COB vs SMD LED Strip: Which Should You Specify?

COB vs SMD LED Strip: Which Should You Specify?

Quick Answer: COB LED strip provides a continuous, dot-free light line ideal for close-view coves and premium interiors; SMD strip uses discrete packages and is cost-effective when viewing distance is greater or deep diffusers hide pixelation. Many hospitality programs use COB in guest-facing zones and SMD in back-of-house corridors.

Introduction

“COB vs SMD” is one of the most common specifier questions on export RFQs. The choice affects guest perception, BOM cost, and whether millwork details need deeper diffusers.

Overview

Technical Differences

COB (Chip on Board) bonds many small emitters under phosphor on the PCB, blending output into one surface.

SMD mounts individual LED packages (e.g. 2835) at fixed spacing — each package is a point source until diffused.

Heat spreads across more junctions on COB at equal wattage; both technologies require profile mounting for long life.

Pros and Cons

COB advantages

- Smooth gradients in shallow coves - Strong CRI 90+ offerings for hospitality - Preferred for brand-critical public zones

COB disadvantages

- Higher $/m - Slightly lower lumens per watt on some SKUs vs high-efficiency SMD

SMD advantages

- Lower cost for long back-of-house runs - Mature supply chain and wide SKU range - Works well with deep aluminum profiles

SMD disadvantages

- Visible dots without adequate diffuser depth - CCT consistency requires reputable bin control

Best Applications

- Specify COB for: hotel guest rooms, restaurants, lobby coves, retail vitrines at close range - Specify SMD for: service corridors, high ceilings, indirect light with deep profile, budget phases

How to Choose

1. Measure or estimate viewing distance to the diffuser 2. Document CCT bin and CRI for both technologies if mixing in one property 3. Match dimming protocol across zones 4. Request run-length / driver maps per technology — do not assume identical electrical layout

Q: Is COB always better than SMD? A: No. COB is better for close, visible lines. SMD is appropriate when diffusers are deep or viewing distance is large.

Q: Can hotels mix COB and SMD? A: Yes, with matched CCT/CRI from one factory. Mihoray supplies both from the same production base to reduce color drift between areas.

Q: Does COB run hotter? A: Heat depends on W/m and profile, not COB alone. Use aluminum extrusion and 80% rated driver loading.

Conclusion

Specify COB where the line is seen; specify SMD where economics and diffuser geometry allow. Export documentation should state technology per zone, not only lumens per meter.
