This 18-LED bulb is available in a single-contact BA15S (1156/1141), or double-contact BA15D (1142/1076) base that is perfect for many types of 360° lamps, anchor lamps, sconce lamps, cockpit lamps, etc. that use a bayonet type bulb. 

For 2016 this bulb has been upgraded with the newest 2835 LED chips, which are brighter and use less energy than previous designs.  Because of this bulb's exceptional output, it is a great replacement for 10W to 25W bulbs. This bulb fits several types of All-Around Anchor Lamps including a Perko 374-001-CLR, and easily meets the visibility requirements for boats up to 60' (20M).

For our Ranger Tug friends: this lamp with the Double-Contact BA15D Base is a perfect replacement for a 20W 1076 bulb as found in your sconce lamps.

NOTE: This bulb works best for omni-directional applications where you need 360° isotropic output.  If your application is an overhead dome light or a bell-shaped reading light, we recommend our Matrix and Six-Gun products respectively.

    No RF Interference

    I had the TV on during a day-long project in the cabin of my Ranger Tug R27. During the day, reception was normal. After the sun set, I turned on two lights with LEDs installed by the previous owner. Strangely, reception on the channel I had on all day started to pixelate and drop entirely. I turned the lights off and reception returned to normal. I repeated these actions and established a direct correlation- lights on-TV off. On a hunch, I replaced the LEDs with ones I had purchased from Marinebeam. End of problem. The warm light bulbs I purchased provide a very nice light.

    Visually, appears to be as bright as the incandescent it's replacing.

    Excellent Product

    Marinebeam LED bulbs tend to be a bit expensive in my opinion, compared to competitors' prices. The quality of the Marinebeam product however, more than outweighs any cost difference. Bulbs are well constructed, robust, and will no doubt serve my needs for a long time. Marinebeam has become my supplier of choice as I continue to upgrade lighting on my trawler.
