Overview
The Imtra DHR40 is a white LED masthead navigation light for 24V DC marine electrical systems. It delivers 3-nautical-mile visibility across a 225° horizontal sector, with IP66 protection against dust and powerful water jets. Its compact design suits masthead installations on vessels under 20 meters in length.
The fixture uses a black, hard-anodized aluminum housing, a borosilicate glass lens, and an epoxy-potted LED driver for protection in marine environments. Its LED technology provides a rated operating lifetime of 50,000 hours, while its serviceable construction allows individual components to be replaced during maintenance.

Both configurations share the same white LED output, 24V electrical requirements, 4.1W power consumption, 3NM visibility, 225° light sector, black housing, and IP66 protection. The mounting method is the distinguishing characteristic.
DH40030000: Base-mount configuration, with the fixture secured through its mounting base.
DH40030001: Side-mount configuration, with a side mounting interface for installations requiring this attachment arrangement.
Installation and compatibility
The fixture is intended for use as a masthead navigation light on vessels requiring a white 225° forward-facing light sector. Installation must maintain the correct orientation and unobstructed visibility required by applicable navigation lighting regulations.
Before installation, confirm compatibility with the vessel's 24V DC electrical system and verify that the selected mounting configuration matches the available attachment surface. The serviceable design allows maintenance of internal components without replacing the complete fixture.
