just a quick update, today I received a little parcel from the component shop full resistors and led's, I ordered what I thought was right, but just to be sure I emailed and asked them to check I gave them the voltages I work with, they were extremely helpful and told me I had got it right, I have tried a random sample and I am a very happy bunny, maplins are kicked well into touch, and if any of the component shop guys are on here many thanks and the same to everyone else who had an input, although we did wander a bit at the end, how we go from voltage reducers to Mike Ashley I'm not sure
