Whilst at Port Vendre marina last week and during cofee on a boat the "Nellie Matilde" of (belgium origin) I saw some what looked like LED cabin downlighters (they looked like the small B&Q type of cheap light you retro fit into the ceiling) whilst I know that these (LEDs) are used on the rear lights of buses and in Traffic lights I have never seen them used in this application they were adequately bright (and the red one over the chart position was exactly what was needed, so as not to destroy night vision. with their record for long life and low useage, I want some!!!. Regrettably, The skipper had no idea where the owner obtained them from, but says he will try to find out. In the meantime does anybody know or has anybody any information regarding them. Oh! they were also used in a strip light form under the steps to the deck and at the base of the masts as working lights, I also believe that they had been incooperated in the compass but couldnt be sure.

How is this for service??

The reply from Holland -

They are made by Hella and marketed in UK by Aquamarine

I hope these are the type you want.

Thanks Philip, just what I need, but a tad expensive, I'll wait until they drop in price!

Some Cheap Ones

A google search using White LEDs showed up these plus loads more.
replacement bulbs for Cars - so they should be able to fit striaght in to the extinging bulb holders. They are made in clusters of 9

I beleive that they are subject to damage with too much voltage though whether or not 14.8 would be high enough to do damage - I don't know.

Re: Some Cheap Ones

If they are for cars, they should be able to take 14.7, as thats the voltage to charge a car battery.

Re: Some Cheap Ones

Thanks, the car ones are very useful to me, as My cabin lights are fine, but these bulbs will be just the job to replace the standard bulbs.

Make your own and save the labour charges. I made my own using high intensity three white LEDS in series with a 150ohm resisitor also in series. For more light you can make up many banks of the 3 LEDS in series and providing the resistor is heavy enough only one is needed in the supply line to the LED banks.

If you are careful you can mount the setup in an old bulb socket break the original bulb glass and epoxy resin glue the thing when you have soldered all the connections or in one case I have four banks [total 12 LEDS] in screw cable connector blocks mounted in an exisiting lamp making use of the old reflector and glass cover.

Re: Some Cheap Ones

LEDs are typically 3 volts - so either use 5 in series -or add a resistor. Can't help with what size - you probably need to experiment.

Can this really be true ( said Alice?) All I have to do to slash electrical consumption on my 29 foot sail boat to miserable porportions is to replace bulbs in the cabin lights with LED car bulbs? What about the navigation lights? This would stop me thinking about solar panels or a wind charger. Bring me back to reality, someone, but be gentle.

That should be possible very soon. Red and Green LED nav lights are available, and offer a significant saving in power consumption over conventional bulbs, but I'm not sure they are officially approved yet.

White light is somewhat harder - the existing "White" LEDs tend to have a significant greenish tinge, and consume much more power than the equivalent brightness red or green. However given the pace of change in this area I don't think it will be long (i.e. a couple of years or less) before this is a genuine possibility.

I did find one company in the US that was offering LED based replacements for the tricolour lights, but they were a couple of hundred pounds.

Thanks to a recent PM. Re my first question, I have just found out who made and fitted the led lights for the belgium boat in port vendre. It is Steve butcher of Rye marine Rye west sussex. He offers a very creative and reliable service, window lights, single wave led for night vision use. step lights for use on deck.
if you want his number please contact me by PM

Very disapointed with the L.E.Ds not a patch on the ones I saw in France, Whilst I guess that they are similar I suppose it is not only the manufacture it is the way that they are used that makes the "French ones" much better, and very thoughtfull and a creative use as well as brighter,

low useage LEDs for cabin and chart table

Anybody got any more comments on these or their useage. I have now spoken with steve who manufactures these in the UK (Rye Marine electronics) it seems that they don`t use hardly and battery at all (I haven`t had time to check mine as yet).

I am however hoping to be able to use one for a masthead light and eventually a cruising light without having to worry about starting the engines in the morning. I Have also spoken with him about converting my navigation lights. I will keep the forum posted
