• Tower Navigation Bayonet LED Bulb,Warm White Item:ILTW1157-SMW

This warm white version of our Tower Navigation Bayonet bulb is a better choice for use behind colored (e.g., red, green, bi-colortri-color) lenses as its full spectrum illumination more accurately produces the color that is desired for your running lights.

This is the highest output LED tower cluster available for marine use. It uses 18 surface mount cool-white (SMD) LEDs arrayed in 6 planes for 360° visibility. Proprietary PWM Constant-Current chipset results in high performance across the entire 10-30VDC range. This LED bulb product may be used in red, green, bi-color, or tri-color navigation light fixtures that use a BAY15d bulb (double contact, offset pins). For anchor or stern white light we recommend our cool white version of this bulb, See ILTW1157-SMC
