LED Converter bulbs for 12 volt bayonet berth lights

[pcatterall]

I'm trying to source some led bulbs to replace the 10watt bulbs in the for and aft berths. These have bayonet fittings similar to standard side lamp fittings in a car.
Possibly I am using the wrong search terms but I can't locate them on ebay type sites.
Can anyone suggest a source please?

Try these on eBay https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/253932523152 lots of different bulb bases to choose from. Measure the diameter of the base of the bulb in mm, stick a b in front of it and that’s the fitting type.

In my experience not worth the bother converting.
Did couple on my boat, precious little increase in light output.
Buy complete LED light.

I'm not sure an increase in the light output is the objective, isn't it more a case of reducing power consumption. It is much much cheaper to change the bulbs rather than the whole fitting. LED's are available in a wide range of light outputs. When I changed mine I bought some cheap ones direct from china on ebay and some more expensive ones from UK specialist firms - 3 years later all still work and give very good light output.

They will therefore be either b15s if they are single contact or b15d if they are double contact

Thanks all. Yes the aim is to reduce power demand. The two lamps in question illuminate the whole of the fwd and aft berths, the boat is in shared ownership with multiple users some of whom do not understand that leaving those lights on can bite into the battery capacity ( about 1 amp each)
The links have been useful, I will have to measure the height of the bulb as there is limited space between bulb and glass. I want to retain the old style glass to keep the 'classic' appearance!

There is some guidance on the Boatlamps website. Their 14 LED lamp replaces this type of bulb

see https://boatlamps.co.uk/collections...a15d-14-smd-2835-high-output-compact-led-lamp

and their 18 and 14 LED lamps replace thsi type

Lots available - you are probably looking for B15S in warm white. Avoid any lamp that says CANBUS - they are for cars and deliberately use more power than the LED needs to trick the car electronics into thinking an incandescent bulb is still there.

Almost every bulb on our boat (lots of interior lights) is now fitted with Ebay or Amazon LEDs, all work OK with no sign of radio interference. Brighter light for less power. For one type of bulb/lamp fitting I did have to swap round pos and neg connectors.

+1 for warm white bulbs from Boatlamps. I find the bluish tinge of non warm a bit harsh for me.
I bought some led bulbs from a boat humble and found they didn't work when installed so if you buy from this source insist that you see them working first. I chose to pay more from Boatlamps to ensure quality products and, as they last indefinitely, the extra cost is spread over many years and therefore insignificant.

Jumble not humble and forgot to mention that the energy saving was well worthwhile.

We have also replaced all our cabin lamp bulbs with LED ones from BoatLamps site.
Not necessarily the cheapest but excellent information for ensuring you get the correct bulb, and all of ours have worked flawlessly since installed 3 years ago. All simple swap over into existing lamp fittings, a very worthwhile upgrade.

2 x bulbs + postage and packing £17.50 ??? and the light output is only marginally better,especially if the fitting is old and internal reflector is tarnished.Do understand the wish to keep stuff original but if you wish to reduce current drain with the bonus of actually having useful light.Something like this this perhaps at a third of that price.

Ughhh its horrid! ( although to be honest I have them as 'overberth' lights but they are pretty well hidden!) but thanks for the suggestion!
We are not trying for more output just less amps for the same. At this time I am still struggling to find replacements with the same light output as was fitted ( tungsten 10 watts)

I purchased something like this for my reflector bunk lights quite a few years ago . Most impressed by the brightness.
