Mars Dome™ Marine LED Dome Lights
Reliable Marine Lighting for 12V and 24V Systems
LED Dome Lights 5½" & 6¾" • U.S. Cree High-Power LEDs • Warm White • Red • Blue
Proven in Marine Service – Dr. LED Mars Dome™ lights have been reliably deployed aboard recreational, commercial, and government vessels for many years. Selected models have been specified for use on U.S. Navy vessels and are trusted by boat builders and marine professionals worldwide.
These lights are surface-mount fixtures designed for boats and other 12V and 24V DC applications. Their regulated 10–30VDC input supports consistent illumination despite normal voltage fluctuations aboard a vessel.
Choose from two fixture diameters, chrome-plated polymer or brass-plated polymer housings, and three lighting configurations: dual-level warm white, red/warm white, or blue/warm white. The ~2700K warm-white output provides a comfortable cabin-lighting appearance, while red or blue modes support lower-light nighttime use.
Whether you need a 12V marine dome light, a 24V marine dome light, a warm white boat cabin light, or a red and white marine light or blue and white marine light option, Mars Dome models are built for marine cabin and utility lighting.
The latest high-power LED technology provides excellent lumen-per-watt performance while using substantially less power than traditional incandescent dome lights. Internal voltage regulation maintains consistent light output throughout the 10–30VDC operating range, helping prevent flicker and protect LED life.
