S4 PAR Retaining Ring is Melting or Losing Integrity


There is a known issue with Source 4 PARs that were built before 2011 where continuous use of the unit would cause the retaining ring to degrade in durability due to the heat.

If you are noticing this behavior on your Source 4 PAR, please contact your local ETC Dealer for replacements parts.
