Overview

The Hella Marine 959700701 is a surface-mount interior/exterior utility lamp that puts out warm white light (3000K) on 12/24V DC systems while drawing under 2.5W. It has a compact footprint at 140 x 65 x 32 mm (5.5 x 2.56 x 1.25 in), making it easy to place on bulkheads, in lockers, or under side decks without eating up space.

This version is w/out switch, so it is meant to be controlled from your existing lighting circuit or a separate switch. The housing is IP67 completely sealed for wet locations, and it is ISO 8846 ignition protected for use in areas where flammable vapors may be present. Power comes in through a 500 mm pre-wired twin-core marine cable.

Key features

• Warm white 3000K output that reads comfortably for interior spaces while still working as a practical utility light
• Multivolt 12/24V DC operation with low draw: < 2.5W (< 0.20A @ 12V / < 0.10A @ 24V)
• IP67 completely sealed for damp compartments, washdowns, and exterior mounting locations
• ISO 8846 ignition protection for installation in higher-risk onboard areas where vapors can be present
• Surface-mount size: 140 x 65 x 32 mm (5.5 x 2.56 x 1.25 in); weight 115 g including cable
• Pre-wired with 500 mm of twin-core marine cable for straightforward hook-up
• UV-resistant, enhanced impact acrylic lens with a heavy-duty nylon shroud and white housing
• Low EMC noise to help avoid interference with onboard radio communications

Installation and setup

Mount the lamp on a clean, flat surface where the wide beam can spill into the area you are trying to light. The fastening load is taken up by the bush mount, which helps reduce stress on the lamp housing when it is tightened down on a bulkhead or overhead panel.

Plan your cable run before fastening the unit in place. The lamp is pre-wired with 500 mm of twin-core cable, so most installs will involve extending the leads with tinned marine wire and sealed connectors. Keep splices out of direct bilge water, leave a small drip loop when mounting under a deck, and protect the circuit with appropriate overcurrent protection as part of your vessel wiring.

Compatibility and fit

This lamp runs on both 12V and 24V DC systems and does not have an integrated switch. If you are replacing an older cabin or locker light that had a built-in switch, plan for external switching at the panel, at a bulkhead switch, or via an existing circuit.

Use the overall dimensions (140 x 65 x 32 mm) to confirm clearance where the lamp will sit and where the cable will route behind the mounting surface. The warm white 3000K tone is a good match when you want utility lighting that feels softer in cabins, passageways, and storage spaces.

Use cases on board

This style of lamp is commonly used for engine rooms, lazarettes, storage lockers, cockpit lockers, and under-deck compartments where you want broad light coverage without needing a recessed fixture. It also works well as a general interior utility light in cabins or under gunwales on fishing boats where wiring access is limited.

Maintenance and care

The sealed construction keeps routine maintenance simple. Rinse salt residue as needed and wipe the lens with mild soap and water to keep the acrylic clear. Periodically check the cable support and any extension splices to make sure they stay dry, supported, and corrosion-free.
