    This is the highest output LED tower cluster available for marine use. It uses 18 surface mount (SMD) LEDs arrayed in 6 planes for 360 degree visibility. Proprietary PWM Constant-Current chipset results in high performance across the entire 10-30VDC range. Choose the cool white model for masthead (anchor light) and stern lamp applications. Choose the full spectrum warm white model for red, green, or tri-color running lights. Both versions fit in fixtures that use a BAY15d bulb (double contact, offset pins).

    Cool White is recommended behind clear lenses because it has a higher luminous output than Warm White. Because LEDs have a narrow spectrum, using Cool White behind colored lenses is not recommended, as the colors will not be true. The Warm White version is recommended for use behind colored (e.g., red, green, bi-color, tri-color) lenses.


    • High output SMD LEDs
    • Exceeds COLREG 3nm visibility requirements
    • Meets visibility requirements for vessels up to 20m
    • Constant-current drive topology
    • Over-voltage protection
    • Thermally efficient design
