So, did you remove R2, R4 and R6?

I spoke to my supplier today and he waffled on about 'Current Limiting Resistors'.

Apparantly, since the board is designed for Red, Green and Blue the resisters are there to 'match' the power to the colour of LED. When you change to white (which has completely different electronic characteristics) you need to change the resistors in accordance ot Ohms Law in order to continue to limit the current.

I have an electronics genuius at work.. I am going to work with him to decide exactly whats needed in order to drive the LEDs correctly to get a near lifetime worth of functionality out of them.
