NO, the rule is that is very unwise to connect LEDs in parallel.  There 
is no problem connecting multiple LEDs in series, contrary to your claim 
above.  LEDs connected in parallel must be very closely matched for 
forward voltage drop so that one LED will not hog the current and 
self-destruct.

Most IR LEDs have 1.6V drop.  Most modern red LEDs have 1.9 to 2.1V 
across  them.  Yellow and green LEDs have a higher voltage, up to 2.4V. 
  Blue and white are 3.4 to 3.6V.

BZZZT!  WRONG!  See above.
Sheesh!  Such misinformation!

----------------(from OED Mini-Dictionary)-----------------
PUNCTUATION - Apostrophe
Incorrect uses: (i) the apostrophe must not be used with a plural
where there is no possessive sense, as in ~tea's are served here~;
(ii) there is no such word as ~her's, our's, their's, your's~.

Confusions: it's = it is or it has (not 'belonging to it'); correct
uses are ~it's here~ (= it is here); ~it's gone~ (= it has gone);
but ~the dog wagged its tail~ (no apostrophe).
