BAY15D 18 SMD 2835 Dusk to Dawn LED Replacement Bulb


SKU: 2130043-C08-BAY15D-OFFSET

Transform your existing anchor lights into a Dusk to Dawn light with our very bright LED anchor bulb with built-in light sensor and the latest 2835 LEDs.

On board voltage spike and excess current protection.

This replacement bulb automatically comes on at dusk, and switches itself off again at dawn. No complicated wiring modifications are required, it’s just a simple lamp exchange.

This BAY15D lamp fits most popular anchor light fixtures including Aqua Signal and Hella Marine plus many more and is ideal for both 12 Volt and 24 Volt systems.

The lamp has has our on-board PWM Buck-Boost constant-current controller and electronic light sensing control. These and our 15 high output, cool white, LEDs combine to give your existing anchor light a considerable boost in light output whilst minimising current consumption by automatically switching on at dusk and off at dawn.

Boatlamps recommend using Contralube 770 on all lamp holder contacts and other connections on your boat. This product will protect against contact corrosion which is the most common reason both LED and traditional incandescent lamps flicker or fail.

The light sensor on these lamps is very sensitive and reliable. Testing by covering with 'woolly hats' or woven fabric often allows just enough daylight through to keep the lamp off. So any testing of these lamps should be in complete darkness, to reflect the normal operational conditions.

We are able to adapt these lamps to BA15D (2 contacts level Pins) and BA15S (one contact level pins) for boat owners who have these lamp holders in their anchor light. This is a time consuming process so we have to make a small charge to reflect the labour cost.

Please regularly check that your navigation light fixtures are water tight. Gaskets harden over time and poorly sealed cable entries are prone to leaking. This is very important for bow mounted fixture that can be submerged occasionally in heavy seas. Our warranty specifically excludes damage to LED lamps due to salt water contamination.

These lamps are not polarity conscious, they are fitted with a 4 independent diode bridge rectifier and can therefore be connected either way without damage.

When mounting LED lamps adjacent to AIS and other sensitive antenna do try to separate the lamp as far as is practicable from antenna to minimise any interference issues.

Important: In common with other replacement LED lamps on the market, it is not possible to have any sort of marine authority certification for individual replacement bulbs. These LED lamps are easily visible at distances exceeding 3nm in standard fixtures and are the brightest replacement LED bulbs available. Given the vast array of navigation light fittings installed on marine vessels, it is the user's decision alone whether to use this product to retrofit any particular light fitting used for navigation purposes.
