forward voltage of LED

post #1 of 3
Thread Starter 
so basically im about to order my leds and resistors, but i didnt know which ones to get. on the specs of the led, it has 3 different numbers for forward voltage.
this is what it says word for word:

1.9V-2.1V Typ, 2.4VMax

do i pay attention to the 1.9/2.1 or the 2.4 max?

luminousity doesnt matter to me because im stringing a good 16 of them together very close to eachother for my shogun mod:

1.9-2.1 is the typical running voltage. 2.4 is the max spike voltage. Running at 2.4v will significantly decrease the life of each diode. Go by the 1.9v, it is better to get too many in a string and undervoltage them than overvoltage and fry them.
