Giant Slaying Performance.

Uncompromising power. Unmatched design. The STEDI™ C4 Marine White takes compact lighting to the extreme — engineered to be the most powerful cube light in its class. Equipped with CREE’s high-output XM-L2 LEDs, the C4 delivers 4,200 lumens of intense illumination, giving you daylight-level visibility long after sunset.

Born from a simple directive — hold nothing back — the C4 stands as the benchmark for marine-grade cube lighting.

⚓ Built for Marine Endurance

The Marine White C4 is designed for the harshest marine environments. A UV-stable, marine-grade white powder coat resists salt, corrosion, and fading, while an IP68 waterproof rating and Gore® breather vent guarantee flawless operation — even when submerged up to 3 metres.

With RFI and EMI suppression circuitry, you’ll enjoy powerful illumination without interference to your GPS, sonar, or radio systems.

🌊 Flood Beam — Total Area Illumination

The Flood Beam delivers smooth, uniform light distribution for near- to mid-range coverage. Ideal for deck lighting, dock illumination, or broad-area work zones, the C4’s homogeneous flood output ensures clear visibility with minimal glare.

Beam comparison:

• Flood Beam: Balanced illumination for general marine lighting.

• Spot Beam: Concentrated throw for long-range visibility.

• Diffused Beam: Soft, wide glow for close-up work or interior lighting.

• Dual Lens: Dual-mode with selectable red/amber diffused illumination for night-vision preservation.

Whether you’re navigating at night or working on deck, the C4 Flood ensures total visual control.

🧊 Coloured Filters Included

Every C4 Marine White includes a set of 3 interchangeable filters at no extra cost:

• Blue Filter – Reduces glare on reflective surfaces such as water and stainless steel.

• Yellow Filter – Enhances vision through fog, haze, and spray.

• Translucent Black Filter – Provides a sleek blackout look and glare reduction.

Snap-on fitment makes swapping filters effortless — perfect for adapting to changing conditions.
