Difference Between COB and SMD Strip Lights and Which One Should You Choose?
If you're planning an outdoor lighting project and considering LED strip lights, chances are you’ve come across the terms COB and SMD. Both are excellent choices, but they serve different needs depending on what kind of light effect, brightness, and budget you’re working with.
At Sun Bright Lighting, we want to make sure you understand exactly what you’re getting, so let’s break it down.
What is a COB LED Strip Light?
COB means Chip on Board. Unlike SMD, COB strips pack hundreds of tiny LED chips close together under a single phosphor layer — giving off a seamless, continuous line of light.
✅ Benefits of COB Strip Lights:
-
Dot-free glow: Perfect for sleek, modern installations where the strip will be exposed.
-
More uniform lighting: Great for under-rail, stair, or architectural lighting.
-
Slim and flexible: Ideal for tight or curved spaces.
-
Better light consistency: No hot spots or uneven edges.
⚠️ Things to Consider:
-
More expensive: Due to newer technology and higher-density chips.
-
Harder to repair: Not ideal if you plan to cut or modify frequently.
-
Fewer RGB options: COB is still catching up in the color-changing space.
What is an SMD LED Strip Light?
SMD stands for Surface Mounted Diode. These are the most common LED strips you’ll see, with visible individual LED chips lined up across the strip.
✅ Benefits of SMD Strip Lights:
-
Tried and tested: A long-time favorite for both indoor and outdoor applications.
-
Available in RGB, RGBW, and CCT: Great for color-changing features or adjustable white tones.
-
Bright and customizable: Different chip sizes and densities let you control output.
-
Cost-effective: More affordable than COB options.
⚠️ Things to Consider:
-
Visible dots: Unless diffused, you’ll notice the "dotted" light pattern, especially at night.
-
Less uniform glow: May cast uneven shadows or brightness across surfaces.
Which One Is Right for Your Outdoor Lighting?
It all depends on where and how you plan to use your LED strips:
| Situation | Recommended Option |
|---|---|
| Need a clean, modern look (no dots) | COB |
| Want dynamic color changes (RGB/RGBW) | SMD |
| Tight budget | SMD |
| Lighting under steps, walls, or rails | COB |
| Planning a DIY cut-and-connect project | SMD |
Our Recommendation
If you're looking for a premium, polished lighting effect, go with COB. It’s perfect for customers who want a clean, minimal glow with no visible LEDs.
If you want flexibility, color control, and budget savings, SMD is your best friend — especially for projects where the strip will be hidden or used with a diffuser.
