Dual contact offset pin bulb fits in most Nav, Steaming, Anchor, and Masthead lights. 30-5730 LEDs provide 800+ Lumens – TWICE the Lumen output of the incandescent bulb you are replacing. 9-20 VDC will allow for large voltage fluctuations. At .125 amps or 1.5 watts, this bulb draws only 6% of the power of your existing incandescent bulb.

Red and Green bulbs available for faded nav light lenses.

THIS DOES NOT REPRESENT BRIGHTNESS.
3200K – Perfect for Nav lights because the warm white light output of this bulb does not overcome the green and red color of the lenses.4100K – This neutral white bulb is good for steaming lights, nav lights (if you have thick red and green lenses), and anchor lights.5500K – This day white bulb is perfect for bright stark white light output for superior visibility for steaming lights and anchor lights.For some of us that have older nav fixtures, the red and green lenses may have faded over time. Our red and green LED bulbs are the answer. They are just as bright as the white bulbs but enhance the colorless lenses of your nav light restoring to more than original brightness without buying a new fixture!

These RED and GREEN bulbs have the same dual contact base with the offset pins.

Typical Anchor Light Fixtures
The diagram below illustrates the way this bulb is designed. The sleeve with the offset pins does not conduct any electricity. Each contact on the bottom provides the + or – power to the bulb allowing your fixture socket to be wired without regard to polarity.


This bulb has been certified by the U. S. Coast Guard for 3 nautical miles.

This vessel has the 30-5730 LED bulb in its navigation and searchlight.

This bulb claims it is twice as bright as its incandescent cousin. My guess is that it is THREE times as bright! Joe was a pleasure to deal with as he guided me through the color choice for my anchor light. I ended up purchasing the 5500K for my anchor, and the 3200K for my nav light.I could not believe the difference. Coming back to my boat that night, there was no doubt which one of the 50 or so boats was mine.
I will be purchasing more of my replacements from Cabin Bright. My neighbors will be too. If you don't see what you need on his website, call Joe. He is slowly putting all the marine LED bulbs he has made on the Cabin Bright website.
GREAT products, GREAT Service,
