Use ONLY Hard Coated filters on a Lambda XL!

I recently learned from Sutter that only Hard Coated filters, such as  Semrock or Chroma ET series. If you have already purchased a non-ET set for your XL remove it quickly! Here are some examples of what will happen otherwise…

Update – Some of my colleagues have noted there are Chroma sets which used mixed filter types. (Some ET and some normal) so – make sure to check that each filter installed into the XL is an ET filter, don’t just assume the set will include all ET filters!
