This is our automatic photocell daylight sensing replacement 15-LED bulb, which automatically comes on at dusk, and turns off again at dawn.

It is a drop in replacement for your existing Aqua Signal, Hella, Perko or other anchor light or tri-color housing with a BAY15D bayonet base (double-contact, offset pins) socket.  No extra sensors, wires, or switches needed.

We have built all of the daylight-sensing electronics right into the bulb, so it is just a simple replacement.  The bulb still features the Marinebeam constant-current electronics, and 15 of the newest multi-emitter LEDs, so its output far exceeds all requirements for all-around anchor lighting for boats up to 20M (65 ft). Perfect for boats on a mooring, or for cruisers constantly on the hook.  Never forget to turn off your anchor light again!

Fits Aqua Signal Series 40, 41, 42,& 50 as well as Hella 2984 and Perko 200 Fixtures.  Replaces Aqua Signal Bulb 90002, 90003, 90005, and 90006 , Hella Bulb # 78290 and Perko Bulb # 037512V10W  Cross References to Hella bulbs: 8GA 003 488-121 8GA 003 488-301 8GA 003 488-131 8GA 003 488-311

  • Voltage: 8VDC - 30VDC Constant-Current Control
  • Wattage: 3W
  • Amperage: 0.25A at 12V
  • Lumens: 240
  • Dimensions: Dia. 28mm x 40mm (+socket)

Marinebeam bulbs feature a proprietary Constant-Current driver and high-output thermally-efficient multi-emitter SMD LED bonded to an Alumicore engineered thermal substrate. All our bulbs can operate on any polarity, and have a custom EMI suppression circuit to prevent interference with radios, GPS, etc. These features combine to give record setting output, superior efficacy (lumens/watt), and the longest service life possible in an LED cluster.

    With only 2.5w this tiny light is saving us lots of power as an anchor light on our boat.

    Works well

    You will need to provide the socket and a housing for the bulb. I use a CLEAR empty plastic bottle with a large cap, drill or punch a hole in the cap large enough for the base of the bulb, put the bulb on the inside of the cap with glue etc. with the pigtail hanging out of the bottle, screw the cap on and the bulb will be inside the bottle protected from the weather! Just mount the bottle somehow to any post on your boat where the light will shine 360 deg. circle, at least one meter above any other navigation light, should be legal anywhere. I have several and on three boats and they all work well, come on at dusk and off at dawn automatically.

    Works as advertised. Helpful that product lists anchor light assembly which support this bulb. Would have given 5 stars but don't know yet how long it will last.
