The Vivid-R datasheet does not specify the size of the gel to use, in particular the R104 that ETC recommends in some cases. What are the gel dimensions for the 11" unit?
The datasheet refers to a spreadsheet where the link is broken:
http://www.etcconnect.com/docs/docs_downloads/techdocs/Selador-Lens-Photometrics.xls
What is the correct URL for this spreadsheet?
