Core diameter, run length, color options, and choosing the right fiber for your application
Ellumiglow offers two distinct Laser Wire product lines: Standard Laser Wire and Laser Wire Prism. Both use light-diffusing fiber optic technology driven by specialty lensed laser modules, but they differ significantly in core construction, maximum run length, and how color is achieved. Understanding these differences is critical for selecting the right product for your project.
Standard Laser Wire uses a 170µm (0.17mm) core diameter light-diffusing fiber. The fiber itself is clear, and the color output is determined entirely by the laser module connected to it. A red module produces red light, a green module produces green, and a blue module produces blue. There is one exception, which is the ICE profile, which has a phosphor coated jacketing, and takes a blue laser and shifts it to the cool white (5000K) light spectrum.
Single-color modules (red, green, or blue) are the most cost-effective option. Each module drives one color through the fiber. If your project requires only one color per run, this is the simplest and most affordable approach.
To achieve colors beyond the three primaries (for example, cyan, magenta, yellow, or white), you need the DMX RGB module. This module combines red, green, and blue laser sources with DMX control for full color mixing. The RGB module is a professional-grade component priced at approximately $800 per unit, making it a significant investment for multi-color installations. The second option for color mixing is adding a different colored laser module on each end, in which we call, "DualDrive". This creates a beautiful gradient along the line, mixing between the two colors. For instance, a red and blue module place on each end produce a purple-pink gradient as it passes from one color to the other.
Our standard Laser Wire measures just 0.7 to 0.9mm in diameter, producing an incredibly thin yet impactful line of light. Each profile distributes that light energy differently. The Super Pop profile concentrates its output over roughly 1m, creating a narrow, high-intensity line that remains visible in most lighting conditions. The Pop profile spreads the same energy across 5m (16.4ft), trading per-section brightness for a longer, more graceful run of light. The Accent profile extends that length again by roughly double, at about half the brightness of the Pop profile.
Standard Laser Wire has a maximum effective run length of 10 meters (approximately 33 feet) when powered from one end. If the module is connected at both ends of the fiber, the maximum extends to 20 meters (approximately 66 feet). Beyond these distances, brightness drops off noticeably due to the 170µm core diameter and light attenuation over distance.
Key takeaway: Standard Accent profile Laser Wire is ideal for short to mid-range runs where a single primary color (red, green, or blue) is sufficient, or where budget allows for the RGB module for full color mixing.
Laser Wire Prism takes a fundamentally different approach to color. Instead of relying on the laser module to dictate color, Prism uses a proprietary powder mixed directly into the fiber jacketing. This powder converts the laser light into the desired color as it passes through the jacket, meaning the color is built into the cable itself.
The proprietary powder in the Prism jacketing acts as a wavelength converter. A single laser module (typically blue or UV) can drive any Prism color, because the jacket does the color conversion. This eliminates the need for expensive RGB modules when you want colors like orange, purple, warm white, or any other non-primary color.
Because color is achieved through the jacketing rather than the module, Prism opens up a much wider range of colors. Standard colors include amber, yellow, orange, pink, purple, teal, mint and more. Custom colors are also available for projects that require a specific brand color or unique shade.
Prism uses a smaller core diameter of 114µm (0.114mm). While a smaller core might seem like a disadvantage, it actually allows the same laser power to propagate much further through the fiber. The result is a maximum run length of up to 500 meters (approximately 1,640 feet). This is a transformative capability for large-scale linear installations like architectural outlines, building perimeters, stadium lighting, runway markers, and long-distance wayfinding.
Key takeaway: Prism delivers more colors at lower cost per run, with dramatically longer maximum distances. For any project requiring runs beyond 20 meters or colors beyond red, green, and blue, Prism is the recommended choice.
The core diameter is the single most important factor in determining how far light can travel through the fiber before brightness drops below usable levels.
Light attenuation in fiber optics is influenced by the core geometry and the scattering properties of the diffusing material. Standard Laser Wire's 170µm core scatters light more aggressively across a shorter distance, producing a bright and intense glow but limiting total propagation. Prism's 114µm core distributes light more efficiently over distance, maintaining visible brightness across much longer runs.
To put this in perspective: Standard Laser Wire maxes out at roughly the length of a large room or hallway. Prism can span the perimeter of a large building, an entire stadium fascia, or a 500-meter architectural installation, all from a single module connection point.
10m vs 500m: Standard Laser Wire reaches maximum brightness distance at 10 meters (20m dual-end). Prism continues with visible brightness up to 500 meters from a single connection point.
| Specification | Standard | Prism |
|---|---|---|
| Core Diameter | 170 µm (0.17 mm) | 114 µm (0.114 mm) |
| Max Run (Single End) | 10 m (33 ft) | 500 m (1,640 ft) |
| Max Run (Both Ends) | 20 m (66 ft) | N/A (single end sufficient) |
| Brightness at 5m | High | Moderate |
| Brightness at 50m | Not usable | Good |
How you achieve color is one of the biggest practical differences between the two product lines.
With Standard Laser Wire, the fiber is colorless. You select a laser module in red, green, or blue, and that module dictates the output color. To get any other color (cyan, magenta, yellow, white, or any mixed hue), you must use the DMX RGB module, which blends all three primaries. This module costs approximately $800 and adds complexity to the system.
With Prism, each cable is manufactured with a specific color built into the jacketing. You order the color you need, connect it to a standard module, and the jacketing does the rest. No RGB module required. This makes multi-color installations dramatically simpler and more affordable. Need orange and purple on the same project? Order one spool of each color and drive both with standard modules.

Important distinction: Standard Laser Wire with an RGB module can dynamically change colors in real time via DMX control. Prism colors are fixed at manufacturing. If your project requires live color-changing effects, Standard with an RGB module is the only option. If you need a fixed color other than R/G/B, Prism is far more cost-effective.

The right choice depends on your project requirements. Here are common scenarios and which product fits best.
Start with these three questions to narrow down your decision:
If any single run exceeds 10 meters (or 20 meters with dual-end power), Standard Laser Wire will not deliver adequate brightness. Prism is the only option for runs beyond that range, and it excels up to 500 meters.
If your installation requires real-time color transitions controlled by DMX, Standard with the RGB module is required. Prism colors are fixed at manufacturing and cannot change after installation.
If red, green, or blue is sufficient, Standard is the simplest and most cost-effective option. If you need warm white, amber, pink, purple, or a custom brand color, Prism delivers those at standard pricing without requiring an RGB module.
