How far away is the electric from the CYC?
The electric is about 8' from the Cyc now but we will re-position it to where it will work best for these fixtures. That is why I am also looking for that information, what distance from the Cyc they should the Source Four LED w/ CYC adapters be set up for them to give the best coverage from top to bottom?
Ideally you don't want to be more than 6 feet back for best results. I have found to 4 to 5 foot range works the best. At 5 feet back that is about 6 fixtures on 6 ft spacing. I would lean towards 7 fixtures at 5 feet back for the best outcome.
Thank you for this. We'll likely go with 7 then so there is an odd number with one in the centre. Should the Source 4's be hung even with the top of the Cyc or somewhat higher (or lower)? Does the app recommend a hanging angle position for this distance and Cyc height? ...or is that indicated on the Cyc adaptor somehow?
The cyc adapters work best when the top of the cyc is even with the top of the adapter. They don't work well if you have to tip the fixture down too much (you'll lose a lot of light on the floor since the vertical spread is very close to 90°).
