Shenzhen, China – September 2026
When it comes to RGB neon strips, the industry standard is typically 5050 RGB LEDs. But for projects that demand higher density, smoother transitions, and more vibrant effects, the 3838 RGB LED is an excellent upgrade – and it’s Drew’s favorite choice.
Drew recently approached us for a custom neon solution using the 3838 RGB chip. The result? A 12×25 round top neon strip that delivers exceptional brightness and color quality in a compact, durable package.

The Challenge: 5050 vs 3838 – Why Density Matters
Feature | Standard 5050 RGB | Upgrade 3838 RGB |
|---|---|---|
LED Size | 5.0 × 5.0 mm | 3.8 × 3.8 mm |
Typical Density | 30–60 LEDs/m | 60–120 LEDs/m |
Brightness | High | High (comparable) |
Color Mixing | Good | Excellent (smoother transitions) |
Best For | General lighting, standard strips | High-density, seamless effects |
The 3838 RGB LED is smaller than the 5050, allowing for higher density while maintaining excellent brightness and color saturation.

Why 3838 RGB? Drew’s Favorite Choice
Drew has consistently chosen 3838 RGB LEDs for his projects, and for good reason:
Advantage | Why It Matters |
|---|---|
Higher density (120 LEDs/m) | Smoother, more seamless light – no visible hotspots |
Better color mixing | Superior blending for vibrant, uniform colors |
Compact size | Fits into tighter neon profiles |
Excellent brightness | Comparable to 5050 despite smaller size |
Flicker‑free performance | Reliable for video and broadcast applications |
“The 3838 is my go‑to for high‑density RGB neon. The color quality and consistency are unmatched.” – Drew, repeat client
