What does wiring LEDs in Parallel mean and is it recommended?

A separate Q&A has dealt with when LEDs need to be wired in Series.

The video below will demonstrate what could happen when LEDs are wired Parallel.

If the LEDs are not binned/matched to be IDENTICAL, then the internal resistance of the LED will determine how the drive current is split between loads. 

For example, If you wanted to use a 700ma driver to power two separate LED modules with the goal of driving each at 350ma, this may or may not work out as planned.  If the LEDs are not identical, then it will not divide as planned.  It is possible one LED module would be driven at 500ma and the other at 200ma if they are wired parallel off the Constant Current driver.
