Do I need to bring a half mile mains extension lead then Andy 

[wideawake]

£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.

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.

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

Yes, multi colour LED's, red green..... didn't notice the rest..... blue, white?

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.

Oh how very pretty, I found it very hard to look away and reply...

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...
