 LightPointNode just states that it should be drawn well after the
 transparent bin.

 Can you tell me the reasoning for this?
 Is it acceptable to change the bin for the LightPointNode on specific
 geometries, or has anyone experienced problems with this?


It should be fine to change the bin number.  The bin number is simply a
choice based on what would work well for most common types of usage but
it's not failsafe.
