Released 2010-10
ETC intends this document to be provided in its entirety.
ETC has improved our lens identification and configuration method for assembling the lens
tubes of Source Four ellipsoidal spotlights. Our new system now accounts for Source Four
Enhanced Definition Lens Tubes (EDLT) as well as original lens tubes. All lens tube
castings are now manufactured to hold either original or Enhanced Definition lenses.
Lens Positions
ETC has added an additional position in the barrel casting for lens placement. We also
have added color-coding for all lens positions. For any lens position, only lenses bearing at
least one dot of the indicated color should be placed in that
position.
Lens position color codes are shown below. Beneath each color you will also find the actual
text as shown within the lens tube, indicating both the color and degree lenses that can
occupy that position.
(additional lens configuration information on reverse)
N o t e :
The information in this document supersedes information in the
Source Four
User Manual and the Source Four Assembly Guide. When assembling the lens
tube for your Source Four ellipsoidal spotlight, refer to this document for lens
identification and placement.
