Overview

The Hella Marine Sea Hawk-470 is a multivolt LED light bar that runs on 9 to 33V DC (12V/24V systems) and is used as a deck, spreader, or forward-facing work light. Output is a 5,000 K white light with 36 W power draw, and the unit is fully sealed to IP 6K7 and IP 6K9K for wet weather, spray, and washdowns.

This light bar measures 528 mm long and 57 mm wide, and weighs 950 g. It comes pre-wired with 2.5 m of tinned multi-core cable and mounts using a polished 316 stainless steel bracket that supports upright or pendant installation.

The lens is made from heavy-duty Grilamid and the housing uses a thermally conductive polymer that pulls heat away from the electronics while avoiding the corrosion issues that can show up with metal housings in saltwater use.

Key features

• Multivolt input for 9 to 33V DC systems (12V or 24V)
• 5,000 K white output with 36 W power draw
• IP 6K7 and IP 6K9K sealing for dust tight protection plus immersion and high-pressure washdown resistance
• Heavy-duty Grilamid lens with resistance to UV exposure, common chemicals, and impact
• Thermally conductive polymer housing for heat management and corrosion-proof construction
• Polished 316 stainless steel bracket with upright or pendant mounting options
• Pre-wired 2.5 m tinned multi-core cable for marine wiring runs
• Reverse polarity and transient spike protection

Variants

This range is offered with either a black housing or a white housing, and each housing color is available with multiple beam patterns.

Beam pattern is what changes the way the light lands on deck and water: a diffused lens spreads light broadly and evenly, a spread beam keeps the focus on close-range deck work, a spot beam pushes light farther ahead, and the spread and spot option combines coverage and reach in one optic.

Installation and setup

Plan the mounting location with the 528 mm overall length in mind and leave room to aim the light bar without the bracket binding. The bracket supports upright or pendant mounting, which helps when you are fitting it under a hardtop, on a radar arch, or on a mast spreader.

Route the cable so it is protected from chafe and standing water. On exposed runs, a drip loop and sealed cable entry go a long way toward keeping connections dry over time.

Electrical and system integration

The Sea Hawk-470 works on 12V or 24V DC systems thanks to its 9 to 33V input range. Wire it to a switched circuit with marine-grade tinned conductors and heat-shrink terminations, and protect the circuit with an appropriately sized fuse for the wiring run and load.

Reverse polarity and transient spike protection adds a margin of protection during installation and when the boat sees voltage spikes, but it is still worth keeping connections clean and tight, especially in high-vibration areas.

Use cases on board

Diffused and spread optics are commonly used for cockpit, aft-deck, and foredeck lighting where you are working lines, loading gear, or moving around at night. Spot optics are used when you want more reach for navigation markers and hazards, and the spread and spot option sits between those two needs.

This light bar is a good match for boats that want a sealed, hard-wearing deck or spreader light that can be installed on either 12V or 24V without adding converters.

Maintenance and care

Rinse the housing, bracket, and lens with fresh water after saltwater runs and check fasteners periodically. If the lens picks up grime from exhaust or fish residue, mild soap and water keeps it clear without attacking the material.
