Semiconductors calculators 
LED series/parallel array wizard
The LED series/parallel array wizard is a calculator that will help you
design large arrays of LEDs. 
LED series resistor calculator
Current limiting resistor calculator for Led's 
LED series resistor calculator
These calculators work out the values for an LED current limiting resistor 
LED calculator:
current limiting resistor value DO NOT use LEDS without a current
limiting resistor in series with the LED. The forward voltage rating is
TYPICAL and can vary from part to part, so while some LEDS may work fine
just connected to a battery of the proper voltage, others will be overdriven
and be destroyed 
LED candela (millicandela) to
lumen conversion wizard compare the light output of LEDs with different
beam angles
