Hi guys, first of all sorry for my bad english. I'm also a noob so this makes an awesome mix.
I'm a bit lost in my project and I need some guidance.
I'm trying to control 5 x 50w RGB led.
I couldn't find the datasheet and the only info that I have is this.
50W:
Color: RGB
DC Forward Voltage (VF): Red 22-24V, Greed 32-34V, Blue32-34V
DC Forward current (IF): 300MA
Out put Lumens: Red 400-500LM, Green 600-800LM, Blue 200-300LM
Wave Length : Red 620-625nm , Green 515-520nm, Blue 455-460nm
Beam Angel: 160 degrees
Life span: >50,000 hours
What I want to do is to control each single channel (RGB) of each led (5x3= 15 in total).
I'm gonna use exactly this psu.

Input Voltage Range 90~132V AC/ 180~260V AC by switch; 254-370VDC
Out 32-36V,0-9.7A
I know that I will have to reduce the output voltage more or less for each channel, that's not a problem, the problem that I have is this one.
Will I be able to use PWM through a transistor (one per channel) to control the intensity of each channel? Will I blow up something?
Thanks for the help!
