hi everybody... just joined the forum as you can tell.
i have signed up as im starting to build a few projects and this looks like the site to help me out.
i have recently build a mood lighting panel using rainbow led's ( hxxp://www.rapidonline.com/netalogue/specs/55-1904e.pdf spec sheet)
i have 50 of these in series with a 11watt 4.8k ohm resistor. this in turn is connected to the mains via a high power bridge rectifier.
the leds all illuminate however some of them are not colour changing (the leds are fine as i have tested them directly with a 3v button cell).
this problem also seems to be a bit random as sometimes only a few will stay on red (the first colour they go) and sometimes it it other leds that stay the same.
i have also noticed if i switch on my soldering iron on the same 13a extension socket a lot of the leds reset back to red then go on with the colour change.
due to this a assume it is a power spike thats causing the issue but i have no idea on how to fix it, there is no need for the leds to change colour all at the same time however it would be nice to have them all change
thanks in advance
