I'm trying to figure out how to determine what power supply I should be using for different types of LEDs for this and future projects.
I have 2 x RGB LEDS:
Forward Current: 350mA
- RED: 6V - 6.6V
- BLUE: 9.6V - 10.2V
- GREEN: 9.6V - 10.2V
I want to run these in parallel with a power supply and was thinking something along the lines of using an LED Strip power supply as my main power source that is 12V - 2Amp - 25 watt.
I'm going to use an arduino and attempt to dim them using PWM with a transistor.
What's the best way to gauge a power supply unit for high powered LEDS including putting them in parallel?
My understanding is that if I'm drawing 20 watts of power, ideally a power supply should be able to output slightly more than you're drawing. The same goes for the amperage?
Is using this LED Strip power supply a bad idea?
