The 18 SMD LED BAY15d in Cool White or Warm White is suitable for masthead (anchor light) and stern lamp applications. Cool White is recommended behind clear lenses because it has a higher luminous output than Warm White.
Because LED's have a narrow spectrum, we don't recommend using Cool White behind colored lenses because the colors will not be true. Use Warm White for bi-color or tri-color lenses, and use 18 SMD LED BAY15d Tower Green Red or Green behind individual Red and Green lenses.
Fits Aqua Signal Series 40, 41, 42,& 50 as well as Hella 2984 and Perko 200 Fixtures.
Replaces Aqua Signal Bulb # 90005, Hella Bulb # 78290 and Perko Bulb # 037512V10W
