Only problem is this driver is a 3 channel colour changer....Red, Blue and green, and each channel will vary to select intensity of colour....not really practical on a standard led
 
What about technically though? I have done disco lighting installs before so am familiar with that side. Along with the above controller I have the DMX link and a DMX controller which I will programme to turn the lights on and off when I want. I'm fine with the programming, and would save me having to buy a load of time switches and DC dimmers as could run it through DMX.

The only issue I can see is that the above driver only gives out 3x 350mA and the LEDs require about 900. Any way around this?
 
The reason they are 3 x 350mA, is each output is a proportional varied colour output, so by adjusting red, Blue and green give varied colours,
 
I know you can have each channel at whatever value at any time, i.e. ch1 (red) at 80% and ch2 and 3 at 0% and will just show red. I was thinking I could maybe have this as the three separate loops of LEDS that I need.

If I put a 3v 1000mA LED on 3v 1000mA supply it'll be fine. If it was on a 1.5v 1000mA supply it would be half brightness, but what about a 3v 350mA supply? Would that also give a lower brightness?
 
We have explained the principle of driving leds, and how they don`t work to voltage increases or decreases, we have also gone into pwm, pulse width modulation to control brightness by timing the leds on & off at speed. Now were going backwards...?
 
Ok Tazz, you're right, I don't quite understand it fully. Apologies. Don't worry, I'll just try my theories in practise and see if it works or goes boom.

Thanks for your previous advice
