HI Thom,

Just read your e-mail relating to your lighting requirements, if you get in touch with Kyje at component shop

(Email Removed - PM Only) very helpful guy and they will make up any configuration you require 6v or 12v.
you can put a voltage reducer in the line so all your lights operate from the same battery.
If you have a smell space to fit your lights into try the altra bright micro LED's they are only 2mm in size,give more light than a grain of rice and use less power.
Good luck
Best regards
Den

HI Thom
I have successfully used LEDs in commercial fittings but it is quite easy to make your own from brass tube using a knife and file.
Be aware that the base of the LED has a wider platform that increases the diameter so you may need to put the lamp on a base to cover this - the light shines thro it otherwise.
Model train suppliers sell 2mm LEDS and you can get surface mount LEDS that are about 1mm square. I use doll house copper self adhesive strip stuck to cabin siedes/roof etc.
I use an electronic circuit to control my LEDS but you would need some experience of electronics to make your own. if you feel this is within your capability I can supply the circuit details etc. The benefit of this system is that you can adjust the LED brightness to suit different light levels. My RMS Olympic has a remote that enables this from a distance.

HI Thom
The sizes of LED's are 3,5,8,10 mm, if you work them off 6v. Red need a 200 ,om,yellow 180 om,all the other colours use 150. if you order them from components-shop they will advise you on them. the long leg on the LED is the positive. I hope all this helps you, the current drawn is very low,

Thank you and Mark for the great advice. I will be going with LED, however I want to make sure they fit into the lamps (lenses) I found for the lighting. I've asked a few ebay sellers for dimensions and hope to have an idea of whether the LED is small enough for this.

Thom
As Mark has indicated grain of wheat bulbs are heavy on current plus they generate a lot of heat and have a nasty habit of blowing and can be difficult to get at to replace.
However it seems like you have already installed the lights so we need to find you a suitable power source. You have mentioned small so I guess space may be at a premium.
If you have room and they will not be too heavy you could use AA or even AAA Alkaline batteries in battery boxes. A four box would give you 6v and if you add another two box this would give you the 9v plus the 3v. Rechargeable batteries will give slightly less volts but would still work and may help prolong the life of your bulbs.
Wiring Would be:
Negative A (Black wire) 4 box Positive B (red wire) 6v
Negative C (Black wire) 2 box Positive D (red wire) 3v
If you connect a black wire to the 4 box Positive B and the 2 box Negative C then the Negative A from the 4 box plus the Positive D from the 2 box will give you 9v.
If you are using a 6v main battery and space/weight is a problem then you could use it in place of the 4 battery box.
Battery boxes should be available locally.
Hope this makes sense and gives you some ideas 😀

HI Thom

The grain of wheat lights you are considering are very fragile, and use a lot of power, I would have a look on ebay, log into the uk site, there are a lot of different LED's out there.

Basicaly they work on about 2volts, if you put several in series you can use 3 - 4 volts, or get a stabilized reducer, this will power all the boats lights.

Mark

The lights I'm looking at are the 'grain of wheat' ones from modelling timbers. As for the search light, I'm looking at the ROB1641 for the boat. Are the grain of wheat ones LED?

I'm in Canada, so our selection of model boat fittings and lights isn't as good as the UK.

HI Thom
Are you using LEDs as the different voltages you quote suggest otherwise.?

Hi
Sorry l didn't say use LED's 😯 😯 😯

Hi
if you go to components - shop on the net, go down to Action, they do a distribution board. There's another way of doing it with resisters, different colours need different resisters, all on 6 volts. I hope this helps.
