Quick Answer
This custom 16×16mm neon strip is engineered for both horizontal and vertical bending, using an 8mm-wide PCB with 84 × SMD3535 RGBW (4000K) LEDs per meter. Operating at DC24V and 25.2W/m, it delivers high-density, flexible illumination with a 5-meter reel and 5 bare wires for input. The specification was developed for a UK client based on a long-term partnership and verified through sample testing — choosing 3535 RGBW LEDs over standard options to match the 8mm PCB width and achieve the required brightness.
The Story Behind the Spec
For clients who work with high-density LED strips, "standard" isn't always enough.
When Nathan from the UK approached us for a custom neon project, we already had years of experience working with his company. We understood their specific requirements for high-density lighting — and we knew that a standard 60 LEDs/m strip would not meet their expectations.
So we recommended 84 LEDs/m instead.
For this particular 16×16 neon profile, the internal strip needed to fit an 8mm PCB width. After testing physical samples, we confirmed that SMD3535 RGBW was the right LED to use — balancing brightness, color quality, and mechanical fit within the 8mm constraint.
This is how custom strip solutions are built: by combining material knowledge, application experience, and real-world testing.

Key Features
1. 8mm PCB Width – Engineered for 16×16 Neon
The 8mm PCB is the critical enabler for this 16×16 neon profile. It allows the strip to fit precisely inside the housing while maintaining the mechanical integrity required for horizontal and vertical bending.
2. 84 LEDs/m – High Density for Demanding Projects
We specified 84 LEDs/m rather than the standard 60 LEDs/m because we knew Nathan's company requires higher-density illumination.
Density | Brightness | Best For |
|---|---|---|
60 LEDs/m | Standard | General decorative use |
84 LEDs/m | High | High-density, premium projects |
The higher density delivers:
Smoother, more uniform light
Better brightness without overdriving the LEDs
Enhanced visual impact for architectural and display applications
3. SMD3535 RGBW (4000K) – Verified Through Sample Testing
The SMD3535 RGBW LED was selected after physical sample testing. It offers:
Dedicated 4000K white channel for clean, neutral white light
Full RGB color mixing for dynamic effects
Reliable performance within the 8mm PCB constraint
4. Horizontal & Vertical Bending – True 3D Flexibility

The 16×16 profile supports:
Horizontal bends — for flat curves and corners
Vertical bends — for changes in height and 3D shaping
This makes it suitable for:
Architectural outlines
Curved signage
3D displays and installations
Creative lighting designs
5. DC24V, 25.2W/m – Efficient and Stable
Operating at DC24V with 25.2W/m provides:
Reduced voltage drop over longer runs
Consistent brightness across the 5-meter reel
Compatibility with standard 24V power supplies
6. 5 Bare Wires – Simple Input Connection
The input side features 5 bare wires with clear color coding:
Wire | Function |
|---|---|
1 (Black) | 24V |
2 (Red) | R |
3 (Green) | G |
4 (Blue) | B |
5 (White) | W |
No output wires are included — the strip is designed for single-end power input.
7. 2 Clips per Meter – Secure Mounting
Each meter comes with 2 mounting clips, ensuring the neon strip stays securely in place along its run.
