On my way to work this morning I was overtaken by a boy racer in a little wizzy thing, and that was all lit up underneath like that boat with pulsating green and blue led's...it looked bl**dy horrible.

Looks better on the boat tho...

They are currently looking at these for cruise ship applicatons as a security measure, i.e.protection from divers.

Yep, I once saw it going down the east coast of the States on a cargo ship about 25 years ago, absolutely amazing.

In the water it does look good.  A whole new thing for Venetian nights.
I do like to see this kind of thing on a car.  Forewarned is forearmed, and it is good to have all doubt removed.

Mmm be Ok for night sailing then {-)

Gib is quite nice (costly) no model shops to speak off UK is fine but I am working the daft hours so sailing in daylight is hard

Excellent indeed, dude.
Last January I bought a whole load of blue 5mm LEDs for the princely sum of £7.00. Each LED has a diamond-shape concave, as opposed to the usual round tops. The light disperses from the sides which gives a nice all-round glow, but without being too much in your face -- looks pretty much like the same effect as those in the above photos. I've been itching to give 'em a whirl but figgered it would kinda pimpy.
How wrong could I be?!

Now I've seen how they look on that Sea Walker, wouldn't them blue's look great on SunnyBob's cruiser!

Are you still doing it.?

I was in a local merchandising emporium yesterday and was drawn, like a moth, to the Christmas lights as usual.
I noticed this years offering was an LED multicoloured set but what caught my eye was the very wide angle of
light distribution, not the usual 60o, (which basically means you can only really see them head on).

The one I saw were clear plastic and I assume some sort of internal prism arrangement to disperse the light.
Ideal for model boats I thought but it says '24volts' on the little transformer..... is that right?

£15 for 80 LED, I'll wait till the sales I think!

In your local pound shops around this time of year,you can get around 30/40 bulbs (for mini xmas trees) for £1,
i got a few red and a few white sets and they run off 4 pencil batts

£15 is not a bad price for 80. Last year a set of eighty would have cost double that down our way. I paid £7.00 for 40 during the half-price sales.
Are the ones' you seen all the same colour?

24-volts is about right. No biggie, though. Each LED will have its own series resistor, so you only need to swap it out for whatever voltage you want them to work with.

Where did you see them? What is the name of your emporium?

Ask Bill, remember the fairy lights on his crappy plastic boat I had to tow around in Llanberis?

By the way it's not crappy now, but you''l have to wait for next Llanberis to see what he's done to it this time %)

That may be the way they're wired up but in practice I suspect that they'll be made up in series strings of as many as possible leaving a bit of a margin in 24 volts and then these strings will be paralleled.   Using a separate resistor for each LED is wasteful of components and power unless each LED needs to be controlled separately.    Given an average LED drops about 2 volts (ultrabright 3 volts) strings of 10 (7 ultrabright) sounds about right with a series resistor to drop the remaining couple of volts.   Each string will pass about 20mA so 8 strings of 10 will consume a total current of say 160mA.  For comaprison 80 LEDs each with a resistor and drawing 20mA would consume a total of 1600mA (10 times as much)

I think that's right anyway.

"I think that's right anyway."

Yeah, right!... you KNOW it's right. You're just letting modesty get in the way, is all.
The ones' I bought came with the usual 24V xfrmr', and you should have seen they way they were wired. Series, parallel, series-parallel, parallel-parallel... you name it. Why they stuck a series res' on each one - and all the same value - is anyone's guess.

Blimey, that's an unfriendly welcome page, for sure.
How do you get to the LED pages?

Got a set from B & Q in the end, about £10.50.

I paid 10rmb for a similar set a couple weeks ago.  Of course the UK plug on yours probably costs more that my entire set, plus you can't forget that B&Q markup...  :o
