Colour frame holder
The colour frame holder is equipped with a spring-loaded retaining clip that prevents colour frames
and accessories from falling out. See Figure 2 .
Step 1: Release the retaining clip by pushing it sideways while gently pulling backwards.
Step 2: Insert the colour frame.
Step 3: Lock the retaining clip by pushing sideways while gently pushing forward.
For maximum gel life with specific lens tubes, refer to the tables below.
W A R N I N G : Make sure all colour frame accessories are locked in position with the
retaining clip before hanging the Source Four luminaire.
N o t e : The performance of saturated colours may be less than desirable in any theatrical
lighting luminaire, especially when equipped with a 750w lamp. For best results,
always use high-quality colour media rated for high-temperature use.
ETC’s optional Conical Gel Extender, part # 7060A1048, will provide maximum
colour media life. For 14° lens tubes, use part # PSF1029. Gel Extenders are not
recommended for 70° and 90° lens tubes due to the extremely wide-angle beam.
A variety of heat shield products is also available from many colour media
manufacturers. Follow the manufacturer’s instructions for the use of these
products.
