Superyacht and Helipad Edge Lighting
Standard IP-rated products fail in marine environments — not immediately, but progressively. Laser Wire® embedded in structural resin becomes part of the vessel itself. This guide explains the method and the zones it applies to.
The Problem
Why Standard Marine Products Fail
The failure mode on marine LED installations is predictable: silicone sleeve delamination. The sleeve is the weakest component in any IP-rated LED strip, and a marine environment attacks it from four directions simultaneously — UV degradation, salt chemistry, thermal cycling, and pressure washing.
IP68-rated LED strip is rated for submersion — but the rating applies to the product in new condition, under lab conditions, without the chemical and UV exposure of a real marine environment. A superyacht's deck lighting experiences fuel spills, detergent cleaning, rotor wash on the helipad, and continuous UV exposure across every annual cycle. Within one to three seasons, IP-rated LED strip installed without encapsulation shows visible degradation — first as color shift and intermittent failure, then as complete failure at the splice points.
The solution is not a better IP-rated product. It is removing the silicone sleeve from the equation entirely.
Resin encapsulation: When Laser Wire® fiber is embedded in structural resin, the resin IS the housing. There is no sleeve to delaminate, no ingress point at splice locations, and no surface-applied component to be damaged by rotor wash, pressure cleaning, or chemical exposure. The fiber becomes part of the structure.
Product — Laser Wire®
Laser Wire® Systems
Laser Wire® is Ellumiglow's fiber optic lighting system driven by an LED laser source. The fiber carries light from the module to the point of emission with no electronics at the installation point — making it inherently compatible with wet, chemical, and structurally demanding environments.
The fiber itself is inert — it carries light, not electricity. There are no LEDs at the installation point, no PCB substrate to corrode, and no heat generation along the fiber run. The LED laser module that drives the system sits in a protected location — a cable chase, a below-deck compartment, or a sealed electrical panel — and the fiber carries light to wherever it needs to be.
For marine applications, this architecture is functionally superior to any alternative: the electronics are not in the hostile environment. Only the fiber is, and the fiber can be embedded in resin, sealed in gel coat, or run through structural channels that are themselves impervious to the marine environment.
Installation Method
The Embedded Resin Method
Embedding Laser Wire® fiber in structural resin is not a workaround — it is the intended installation method for permanent marine applications. The fiber is positioned in the channel or form, the resin is poured or injected, and when cured, the fiber and the structure are one component.
Channel or form preparation
Route or machine a channel in the substrate material — GRP, carbon fiber, aluminum deck plate, or custom-cast components. Channel depth and width are specified by fiber diameter and resin layer requirements.
Fiber positioning and routing
Laser Wire® fiber is laid into the prepared channel. Bend radius minimums apply — the fiber is flexible but not infinitely so. Corner transitions are made with gradual curves, not right-angle bends.
Resin encapsulation
A clear or tinted two-part polyurethane or epoxy resin is poured or injected into the channel over the fiber. The resin cures around the fiber, creating a monolithic sealed unit. The resin surface can be finished flush or slightly proud of the surrounding material.
Module installation in protected space
The LED laser module is installed in a below-deck compartment, cable chase, or sealed enclosure. The fiber run connects from the module, through a watertight penetration, to the encapsulated installation zone on deck or at the hull.
No exposed product surface: Once embedded, there is no Laser Wire® product surface exposed to the marine environment. The only exposed material is the cured resin — which is itself a structural marine material. The lighting system has no failure mode that the environment can access.

Application
Vessel Zones
Deck Edge and Hull Waterline
Continuous fiber runs along the hull-deck join and at the waterline. Embedded in the hull gel coat or deck edge composite. Visible at anchor and at speed — a continuous line of light that defines the vessel profile at night. Survives pressure washing and salt water at operating draft.
Gangway and Step Edge Lighting
Step nosing and gangway edge lighting is a safety application as much as an aesthetic one. Fiber embedded in non-slip step materials provides continuous edge definition without any surface component that could be a trip hazard or degrade from foot traffic.
Below-Waterline Hull Lighting
Laser Wire® fiber embedded in hull fairing compound at and below the waterline. No LED components in the water — the fiber only carries light. Visible above and below the waterline at anchor, providing a continuous lit hull profile. Survives haul-out and anti-fouling application cycles.
Superstructure Accent Lines
Horizontal accent lines across the superstructure, running from bow to stern along styling lines. Embedded in the GRP or aluminum panel joints. Provides the impression of a lit outline of the vessel at distance — visible in the dark from other vessels and the shore.
Specialized Application
Helipad Perimeter Lighting
The helipad is the most demanding position on the vessel for any lighting product. Rotor wash, fuel spill exposure, the physical loads of landing operations, and the requirement for consistent output make it an environment where conventional LED products are not suitable for permanent installation.
Laser Wire® embedded flush in the helipad deck surface resolves all of these constraints simultaneously. The fiber is below the deck surface, encapsulated in resin that is continuous with the deck structure. There is no raised edge, no surface component subject to rotor wash, and no electrical component in the exposure zone.
Perimeter definition: A continuous fiber run around the full helipad perimeter provides consistent edge definition from any approach angle. The fiber output is not directional — it is visible from all angles, including from directly above on final approach.
