If you're comparing COB vs SMD LED strips and wondering what the fuss is about, here are the 7 differences that actually matter for your project.
1. Light Uniformity (The Biggest Difference)
COB (Chip-on-Board) packs 320+ LEDs per meter, creating a continuous line of light with zero visible dots. SMD strips have individual visible LED points, especially in bright conditions or reflective surfaces.
2. Appearance
COB looks like a linear light fixture - perfect for exposed installations like shelf lighting or cove lighting. SMD looks "dotty" when exposed, better hidden in diffusers.
3. Color Rendering
High-quality COB strips reach CRI 90+ (some up to 95), meaning colors look natural - important for kitchens where food should look appetizing.
4. Price
COB is generally 20-40% more expensive per meter. Worth it for visible installations, less so for hidden strip behind furniture.
5. Flexibility
Both bend around corners, but COB strips are typically thinner (4-8mm) making them easier to tuck into tight spaces.
6. Heat Management
COB distributes heat more evenly across the strip, which can extend lifespan in enclosed aluminum channels.
7. Dimming Compatibility
Both work with standard 12V/24V PWM dimmers, but COB tends to dim more smoothly without flicker at low levels.
Our Recommendation
For visible or premium installations (open shelves, kitchen under-cabinet, cove lighting), go COB. Our 12V COB LED Strip Light Kit delivers dotless 3000K light at CRI 95 with remote dimming.
