Michael DeStefano Posted May 5, 2016 Share Posted May 5, 2016 Maybe from cooling off too fast? If you are looking for a replacement for the M90 2-piece lens?, we can do $442.50 Quote Link to comment Share on other sites More sharing options...
Michael Pimentel Posted May 5, 2016 Author Share Posted May 5, 2016 Well there is melting in the middle of the lense, thus resulting in the lense cracking? Have you or anyone you know experienced this? FYI only on the M90 with an osram 9k hmi 1 Quote Link to comment Share on other sites More sharing options...

This for 6k/9k hmi Hi Michael, every time you turn off the light 1./ you have to dimm the light to the lowest, 2/. put the bulbs backward, leave lit light for 2, 3 minutes. then, cut off power. this will help. besides, as you did the above, it will be more safe when you start up the light next time as there will limit the surge of the power. hope that will help in the future.

Keeps the lens from cooling down to fast. Quote Link to comment Share on other sites More sharing options...
