- Vendor STEDI
- SKU LEDMARINE-C4-DIFFUSE
The STEDI Marine White C-4 LED Cube Light (Diffused) is the ultimate near-field work light, designed to provide a smooth, edge-to-edge "cloud" of light. While the Flood version is built for distance and width, the Diffused beam is specifically engineered to eliminate hotspots and shadows, making it the perfect choice for deck work, docking, or illuminating a campsite.
Superior Near-Field Illumination
The C-4 Diffused light is all about quality of light over raw distance:
-
Homogeneous Diffused Beam: Features a specialized lens that creates an almost cloudy, ultra-wide light distribution. This is ideal for tasks that require clear visibility right in front of the light, such as baiting lines, engine maintenance, or boat ramp loading.
-
Giant-Slaying Output: Packed with 4 x 10W CREE XM-L2 LEDs, this compact cube produces 2,600 raw lumens (capable of up to 4,200 lumens in peak intensity).
-
5700K Natural White: The color temperature is balanced to provide excellent clarity and detail without the harsh blue tint found in cheaper LEDs.
-
Silent Circuitry: Engineered with RFI and EMI suppression to ensure your marine radio and electronics operate without static or interference.
Hardened for the High Seas
-
IP68 Submersible Rating: Fully dustproof and waterproof up to 3 meters. It features a genuine Gore™ breather vent to manage pressure changes and prevent internal moisture buildup.
-
Marine White Die-Cast Housing: The tough aluminum housing is finished in marine white, specifically designed to resist UV degradation and salt-air corrosion.
-
304 Stainless Steel Hardware: Includes a heavy-duty stainless steel U-bracket and an 8mm mounting bolt, ensuring a rust-free, secure installation.
-
Impact-Resistant Lexan™ Lens: A high-optical-grade polycarbonate lens that can withstand impacts from flying debris or heavy spray.
Versatility & Accessories
Every C-4 unit includes three interchangeable snap-on filters at no extra cost:
-
Yellow Filter: Cuts through heavy fog and sea mist.
-
Blue Filter: Reduces reflective glare off white fiberglass decks or choppy water.
-
Black Filter: A protective translucent cover for when the light is not in use.
