Resistor Question for LED Fan Project

post #1 of 2
Thread Starter 
I want to run 8 of these in parallel as a series configuration would be simply too messy.

I could run 2 sets of 4 in parallel if I have to but I don't want it anymore complicated if I do not have to.

http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=60_357_235&products_id=2545
Specifications:
Source Material:InGaN
Emitting color:Red
Lens Type:Water Clear
Luminous Intensity-MCD:4000 Typical/5000 Max
Reverse Voltage: 2.7 V
DC Forward Voltage:2.0V Typical
DC Forward Current:20mA
Viewing Angle:15 Degrees
Lead Soldering Temp:260o C for 5 seconds

What resistor do you recommend for this?
Tolerance, watt, OHM rating, etc.
Any advice would be helpful.

I figure I can buy them from digikey.com again.
