DuraLED 36 Interior/Exterior Lamp - White/White ClamshellHella Marine DuraLed Heavy Duty LED Lamps provide powerful white light and a safe, energy-efficient, and reliable alternative to incandescent and fluorescent lighting. Purposely designed for engine rooms, storage lockers, and many heavy-duty applications where reliability must not be compromised. Advanced HELLA Marine lens and optic engineering ensure an ultra-wide spread of light without glare or harsh light points. The range offers three peak intensity levels, all with a very wide spread of light. Product reliability is second to none, proven worldwide in thousands of highly demanding applications. Each lamp is completely sealed, impact resistant, and shock resistant, ensuring an ultra-long service life. Each lamp is pre-wired with 2.5 meters of twin core marine cable for time-saving and completely sealed electrical connections. Hella Marine Multivolt circuitry provides constant illumination and circuit protection from 9-33V DC, even under severe voltage fluctuations. Spike protection, reverse polarity protection, and over-voltage protection are all built-in benefits of the sophisticated electronics inside each lamp. DuraLed lamps carry ISO ignition protection approvals for safe and certified installations when lamps are located near flammable gas sources such as machinery spaces, tender garages, and fuel storage areas. DuraLed lamps are surface mounted and feature a unique installation system where the fastening load is taken up by a heavy-duty nylon bush to eliminate possible stress on the lamp housing.
