 Our Kr/Ar laser was replaced twice in three years, I feel this is
extremely good. The second laser was under warranty and lasted almost a
full 2000 hours, according to the meter on the laser.  I feel that BioRad
did everything that they could to speed along the process, from my
recollection ILT takes a long time in producing these lasers, and sometimes
does not produce them to the quality BioRad expects.
I called ILT in January they told me that the Average life of a Kr/Ar laser
is anywhere from 200-2000 hrs. They indicated that this number may not be
the case for use in confocal scopes but that the lower number was from
heavy industrial usage and that if used infrequntly the life would be
extended and possibly hit the higher number.
If you have to replace your laser I would go for a refurbished laser.
