Hi!
I bought some 3W RGB Leds, and I dont finish to understand their specifications:
product link: http://www.ebay.com/itm/1-100pcs-x-...hash=item33a6775a97:m:m7spR0mf9AScVUfLSqRkjRQ
Specifications:
LED Emitter: 3W RGB (Red,Green,Blue)
Lumens: RED:25-35LM,GREEN:40-50LM,BLUE:25-35LM
DC Forward Voltage (VF) : RED:2.3-2.6V,GREEN:3.4-3.8V,BLUE:3.4-3.8V
DC Forward Currect (IF) : 350-1000mA
Wavelength: RED:620-650NM,GREEN:520-530NM,BLUE:465-475NM
Beam Angle: 120 degrees
LifeSpan Time : > 50,000 hours
is it possible that the forward current for each led goes from 350 to 1000mA?
I would like to control their intensity using PWM with arduino, but I am not sure what to use for this. I´ve read that a mosfet is appropiate for this application, but I never used one, and I wouldnt know how to choose one for these leds.
Some guidance would be lovely.
have a nice day!
